10:01 No, what's happening is that those phones are able to format a drive using an out of (strict) spec FAT32, not exFAT (also called FAT64). FAT32 is limited to 32GB by MS for practicality reasons (and also to push NTFS), but it can actually access a drive up to 2TB using 512KB (yes, kilobyte) sectors or 16TB using 4MB (yes, megabyte) sectors, which is fine for large files, but then any file smaller than the sector size will always take up an entire sector EACH (until you defrag the partition). Also, any file which takes up a full sector, plus 1 byte, will take up 2 full sectors. so, if you have a 4MB (4,194,304 bytes) sector size, and you have a file which is 4,194,305 bytes, it will physically take up 8MB of space. MS is limited to 4096byte sectors to limit that fragmentation. Any device which correctly supports FAT32 will read the out of spec format just fine, including Windows XP machines (not older, though), you just need a formatter which will create an out of spec partition.
Really informative video, but a simple illustration or table or graph that says what format works and what doesn't work will be much easier for people to grasp, instead of pure listening. I watched twice to fully understand this video.
Jason K I agree with you.A table would be much better, although I understood what he said the first time. Maybe because of my previous knowledge of this subject.
No Name In short: All cards work, though in some phones/devices you’ll have to format them as FAT32 and consequently won’t be able to store files larger than 4GB.
Finally a guy who's capable of explain such an important issue in an understandable way, congratulations Gary, and looking forward to see the logical lecture: How FAT, FAT32, NTFS and ex-FAT handle the file sizes in the same pedagogical way you made this one.
i study computer science and what i can tell you is that FAT32 will and should work well with sd cards up to 500gb max as what my teacher told me. just because it's called FAT32 doesnt mean it can only handle 32Gb that's a load of bull. 32 was meant for 32bit if im not mistaken and it will very well support drives higher than 32gb. limitation: -file size creation (like videos and so on that's why it's only 2 hours max in some devices for videos and so on) -the amount of sub folders that you can create within them. (i forgot how many but its not that much) -get's fragmentation problems and becomes inefficient with bigger drives (if its more than 500gb or more than 320gb stick with NTFS or extendedFAT) -security: if you have lots of data on a drive that is bigger than the said drives then you might run into some problems like lost or corrupt data. that's why microsoft made the NTFS because it's safer more efficient and is quicker.-less fragmentation on hard disks. ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- advantages: -compatability -simpler ---(i think)--- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- -FAT32 is ideal for small drives as they need less tables to operate them from what my teacher said its great for small memory devices like sd cards and flash drives. -note: i formatted one of my extra drives with FAT32 that's a 320gb drive and it works FINE. no problems just defragment it when things start to slow down. i did it for funziez -extra note: playstation3's uses FAT32 from factory and works fine and you see those sporting 500gb these days. well this is a long comment.. *drops virtual potato* :D
Very informative. I searched all over the net and couldn't find the answers I was looking for in regards to how much expandable memory my phone could expand to until I watched this video .
Off topic slightly here but isn't it amazing how much flash memory fits on something as small as a microSD card the literal size of my fingernail and how cheap it is (256gb for ~$22 in 2022).
To enable exFAT support on Linux for distribution that use apt as package manager like Ubuntu you can just open a Terminal and give this command: sudo apt-get install exfat-fuse exfat-utils Reboot the system and you're done, you now have full exFAT support on your Linux system and you're able to mount, read and write removable drives. You're welcome
Yep, the Linux foundation can't quite include exFAT and NTFS support built in for legal reasons, but of course people have reverse engineered drivers for those filesystems
Bought the same for my z5, sadly with the marshmallows update they stripped the function to adopt the SD as internal. thankfully there I was able to adopt it but it is a little complicated and officially not supported
, as of a few days ago, for less than $20 & in a non-open market country (meaning, different from america), i was still able to get a 128gb micro sd sanDisk. for $60 i'm now seeing deals for a half terabyte..
This video was really informative! Been a while since the last time i saw such a straightforward, simple and valuable video in just under 15 minutes! Great work!
You've only done half the job here Read off and Write to these SDXC cards that have been reformatted and tell many if you get any failures. Also, do you get full storage as shown on card?
I lost 3 hours of footage because I didn't know my old camera didn't recognize exFAT from my 64Gb card and kept writing over older files. Very sad, but now I am improving my knowledge about that. Going back to my 32Gb card. It should be noted that sometimes it appears to be working, but it is in fact doing something strange, like overwriting it's own data over and over, so from now on I always follow the manufacturer's advice.
but did you test if those phones with 32GB limit will write any data when the that limit is reached despite the card being formatted has more capacity. i remember vaguely an mp3 player, back when mp3 players were a thing, when i bought a higher capacity storage it just never read the songs beyond that or when it did get to a song that just passed the threshold, the player just crashed. it was a phillips or sandisk player.
What I don't understand is why the Android phone manufacturers simply didn't go with an open format such as ext4 for the larger SD cards; it would have been *free* for them to do so. Ditto for other equipment manufacturers, such as TV, photocopiers, etc. The only roadblock would have been Windows' current inability to recognize this filesystem, but AFAIK, with the right driver added, Windows should be able to recognize it as well as exFAT.
That's the most useful video I've seen in years. I couldn't read my 128gb card from my phone in my win XP PC. This explains everything. I hate the fact that everyone has to pay Microsoft though.
No, it's not just not to confuse customers. Samsung actually restricts the size of the cards you can put into their phones for some reason. My last phone could read a 256 GB card but not a 400 GB card. Which is incidentally the limit of my current phone, even though 512 GB cards were already a thing when I bought it.
It is best to format micro sd card in FAT32 format before using. I current having problem when I transferred videos/pictures from internal storage in my phone to the external micro sd card.Some of the videos/pictures are corrupted. Do you know why? It is because I dont format the SD card correctly?
I'd like to see an informative video about sd speeds too. How important it actually is on a smartphone if i am going to use it only for photos and music or if its going to be used for apps too. do the apps run slower in a slower sd etc .
Is the writing speed the most important factor when looking for my first SD card for my smartphone (Nokia 7+) I want it for saving video files, ie from the camera app. Currently it seems the maximum film(s) I can save is about 30-40 minutes only .... Perhaps made up from 10 short clips. If I am near home I can easily transfer these to my computer then start filming again, but if I am further away I'll need more memory. Have you are preferred card for early 2020 please ? Thanks !
Nice video. I thought I'd share my experience. Now I have no idea if this works for exfat but I had a usb drive formated in ntfs. While android didn't show it as recognized, I was able to read and write to it using es file explorer.
Am I right in assuming that even though a FAT32 card has a 4GB limit on the size of a file stored on it - if a file that you want saved is larger than that size the card will still save the data, but it will store it in multiple files?
I have a Maven 2 (ZTE). Since I had problems understanding you, you said I can get a micro card of 64GB but will have to reformat it when I try to use it in my phone? The phone will do this automatically?
Interesting theme. One more thing is that you can't store file bigger than 2GB on FAT formatted storage. Regardless all that said in this video, what should I do with (e.g. HD or 4K video) single file which is bigger than 2GB and I must format my SD card/USB flash drive into FAT32 so it can be recognized by my tv?
Hi Gary. Could you please tell me if there is a way to get a custom rom (especially cyanogenmod) for unsupported phones? I have a Chinese phone. Like are there any processor specific roms available? I'd really appreciate your response.
"... Compression wrecks performance." Depends which CPU you use. Input-Output is faster; smaller file sizes. Using a fast, multi-threaded CPU, makes things faster again.
Hi Thanks for the video. I just bought a samsung evo select 128GB MicroSD in Green colour from USA, when trying to format it, I see exFat as file system which makes sense but I not sure if the default file allocation of 128 kilobytes is correct? any advise?
I bought a 32gb microsdhc. for my camcorder made a video but when I install it into my phone there's no sound but sound when I play it on the camcorder I have a android Samsung prime so I can't send it anywhere cause no sound could you help me
So, you can only format it to FAT32 on a phone? I got the gyst of it early on, was waiting for you to show a link on were I can format the ExFAT to a FAT 32.
+Gary Sims yeah! it is available. very expensive though. Will the pricing be by the same norm? I mean will 200gb become cheap when there is 400gb available in the market?
I once owned a parrot bebop and if the video file size went over like 4gb or something the files would not transfer at all on to my Mac. I wonder if it was the android holding back or if I had used a Microsoft os if it would have worked. Either way, from the sound of it, I'd prefer to have a device and card that work with xfat based on my past issues.
Can you help? Why does my Samsung SkyPro wipe the micro SD card when I power down EVEN when the card has been unmounted first? Have not been able to find answer on Google.
MY Samsung MicroSD 256 GB does not take large files. For instance, instead of copying a large music file from my PC to micro SD with many albums in it, I had to do one album at a time. Even then, many times the PC would show that the files were being copied to the MicroSD, but when I opened it, the file was empty. It's very frustrating and time consuming.
Great tutorial but I now need HELP PLEASE. I have an android tv box the Minix Neo U9-H but wish to increase the (internal) storage a little with a micro sd card my help is please can you tell me what 32gb (fat32 I guess) make and model of card the box will accept preferably without having to mess about formatting it. I have just corrupted 2 scandisk extreme pro's 32gb and blown £40.00. TYIA.
What about the new PNY 512gb micro SD card... do I have to format that as FAT32 to make it run in a phone like a LG v40 which is rated at 2tb capacity? It seems like a stretch since there's a big difference between 512 and 32
I once plugged in a normal USB hub connected to a power bank (just to power the HDD), a 2 TB NTFS HDD, mouse and keyboard and it all worked on the stock ROM of my S4. Though the screen broke later, so I sold it. I also just used Paragon for it. Now I have an S9+ with
Great Video and information, I agree with Jason K about how a graph would certainly expedite the knowledge crystallization. I have never had any issues with swapping in higher capacity cards in my Motorola Droid2,, Droid4 and Wifeys SG5. Until I upgrade my phone again I have been granted a temporary reprieve with the Droid Turbo (64GB and sans MicroSD slot).
I'm just a bit confused. If FAT32 functions with max file sizes of 4GB then how can you use a 128GB USB? That is beyond the working range of FAT32. Shouldn't any device formatted in FAT32 be read as 4GB storages?
I've had bad luck with cards over 16Gbytes. They seem to be corrupted by the device. I've had two 32G cards corrupted to the point nothing could read them or even reformat them. With 16 and 8Gbyte cards the card has worked well. A few APK files got corrupted but the card remained usable. I've never tried any bigger than 32Gbytes. It seems the curruption is related to the battery running down the the point the device shuts down. When this keeps happening the card is damaged beyond formating eventually. Is there something I'm doing wrong or is it these powerdowns.
I bought a mini usb style mini pc which runs on android its got a usb port so i put on a 128 gb mem stick and i also got a micro sd card at 16 gb both memory thing get read but not at the memory they are the stick reads at 11 mb and the sd reads at 3.5gb what can i do to get the full memory. Can you please advice. Do you think i should format it using the mini pc as originally i did it on a windows pc. Many Thanks
I have a 32 gb card and I formated it with exfat because I have to save files larger than 4 gb but files seem to corrupt very ofter . I am using huawei honor 8 lite and it does support upto 128 according to huawei. Can it be something with the filesystem.....? Please explain......
@AndroidAuth sir, I had a usb storage of 8gb frm Sony.Once I formatd it in COMPUTER running Linux Os..afteron usb drive didn't work for me.Windows didn't detect that usb drive.. can u suggest a solution to recover back my pendrive to original working condition.
I bought a brand new 2021 android radio and for sum dumb reason it wont read a flash drive larger that 32, is there anything thing i can do to circumvent this??
I have a strange issue. 128GB Samsung Evo plus runs good on PC with exFAT (92R/65W). But on Samsung S20 (78R/35W). If the phone's uptime is more than 1Day then speed drops further to (22R/16W). Tried formatting inside the phone which makes it ext4 and it doesn't change anything. Yes speed increases a little bit but after 1Day same drop. I have a Android One device with SD Card support which doesn't have this issue. The android One device doesn't support exFAT though. Moreover another SD Card with 16GB SanDisk Extreme FAT32 on S20 never drops in speed even with multiple days of uptime.
Yes, and it does when you select "expand internal storage" in the phone's storage settings (note that doing this deletes all data currently on the card), well, either ext4 or f2fs by default. Sadly there is no option to just normally use ext4 without rooting (at least wasn't on Android 8.1.0 where I tested), even if you would know you would never need to use the card in Windows. I think it's stupid that Android artificially limits what file systems you can use, even when there is support for a whole host of them in Android.
That was quite an informative video!! But had a query to make. Will putting a card bigger than 32 GB in a phone that officially supports only 32GB of external expandable storage affect its performance in any way? Like R/W speeds or lags?
I had a 32 GB PNY Micro SD card in my Galaxy S4 and I even day I woke up and the phone acted as if I didn't have an SD card. I put it in an SD adapter and went to the computer and the computer didn't read it either. Nothing reads it!!!! Any ideas on what might of happened? or if there is a way to recover it?
can someone explain to me why on the older android systems writing to a USB flash drive via micro to USB female adapter was snappy and efficient. now however on Android marshmallow (what im using now. not sure about the latest ones) it literally takes several hours for a few movies. ive scoured the Internet with no understanding at all.
When I connect my Action Cam's Micro SD card to my Galaxy S7 using an OTG cable and reader, somehow different files get added to the Micro SD card automatically. Seems like some Android files or something. What are they? and can I stop them being added automatically?
What would happen if I put a 64gb card in the Samsung S7, which I formatted on my computer in FAT32, would the card be returned to exFAT if I format it in my phone?
Why does the SD association define what filesystem I can put on my sdcard? Am I forbidden to put my own onto it? Do they license filesystems as "SD card compatible"?
Actually The original SD could support up to 4GB as well As there being SDHC 4GB cards. The SDHC format phased out the SD format while the 4GB SD theoretical maximum was reached. Also SDHC has a naturally higher transfer speed VS SD so that was another factor why you almost only saw 4GB SDHC cards.
you seems like a teacher and I wish all teachers were like you..... great video man
Same🙈
+ziad ahmed I wish my teacher will never be like him, He should get a real job, that old hag

10:01 No, what's happening is that those phones are able to format a drive using an out of (strict) spec FAT32, not exFAT (also called FAT64). FAT32 is limited to 32GB by MS for practicality reasons (and also to push NTFS), but it can actually access a drive up to 2TB using 512KB (yes, kilobyte) sectors or 16TB using 4MB (yes, megabyte) sectors, which is fine for large files, but then any file smaller than the sector size will always take up an entire sector EACH (until you defrag the partition). Also, any file which takes up a full sector, plus 1 byte, will take up 2 full sectors. so, if you have a 4MB (4,194,304 bytes) sector size, and you have a file which is 4,194,305 bytes, it will physically take up 8MB of space. MS is limited to 4096byte sectors to limit that fragmentation.
Any device which correctly supports FAT32 will read the out of spec format just fine, including Windows XP machines (not older, though), you just need a formatter which will create an out of spec partition.

Really informative video, but a simple illustration or table or graph that says what format works and what doesn't work will be much easier for people to grasp, instead of pure listening.
I watched twice to fully understand this video.
Jason K I agree with you.A table would be much better, although I understood what he said the first time. Maybe because of my previous knowledge of this subject.
This is all so confusing, fat that works and fat that doesn't work. Instructions unclear, going on fasting diet to lose all fat.
No Name In short:
All cards work, though in some phones/devices you’ll have to format them as FAT32 and consequently won’t be able to store files larger than 4GB.
I got it the first time through and found the details interesting.
I thought it was fine, but maybe I'm too well versed in formatting and filesystems.
Finally a guy who's capable of explain such an important issue in an understandable way, congratulations Gary, and looking forward to see the logical lecture: How FAT, FAT32, NTFS and ex-FAT handle the file sizes in the same pedagogical way you made this one.
I use exFAT on all my internal and external hard drive, simply because NTFS Security/Permission screwing up when standard user vs admin user profile.
i study computer science and what i can tell you is that FAT32 will and should work well with sd cards up to 500gb max as what my teacher told me. just because it's called FAT32 doesnt mean it can only handle 32Gb that's a load of bull. 32 was meant for 32bit if im not mistaken and it will very well support drives higher than 32gb.

well this is a long comment.. *drops virtual potato* :D
he didnt say that . dont waste potatoes real or virtual.
Very informative. I searched all over the net and couldn't find the answers I was looking for in regards to how much expandable memory my phone could expand to until I watched this video .
gary and juan (from pocketnow) are the 2 best techies imo
Agreed.
Very hard to argue with that.
Agree :)
Agree!
Yes they are, but you missed Captain2Phones ;-)
Off topic slightly here but isn't it amazing how much flash memory fits on something as small as a microSD card the literal size of my fingernail and how cheap it is (256gb for ~$22 in 2022).
I really like Gary's clear, concise teaching style. I hope he keeps adding content.
i love this man ! he is awesome, the best in android authority team 👍
watching this 10 months later and it made me learn new info, thats when you know how good the video is.
It's good to see you again, Sir. I always learn something useful from your videos. Thank you.
Or just format as ext4, most Android phones use that as their filesystems by default.
To enable exFAT support on Linux for distribution that use apt as package manager like Ubuntu you can just open a Terminal and give this command:
sudo apt-get install exfat-fuse exfat-utils
Reboot the system and you're done, you now have full exFAT support on your Linux system and you're able to mount, read and write removable drives.
You're welcome
Yep, the Linux foundation can't quite include exFAT and NTFS support built in for legal reasons, but of course people have reverse engineered drivers for those filesystems
I can't get enough of these videos. Keep it up Gary!
your explanation is more clear and easy to understand than my computer science professors.. And it was actually interesting :)
F*** patents ... I wish all systems had native ext3/4 FS support at bare minimum, opensource and free, not mentioning that it is faster than exFAT.
I wish systems actually supported GUID partition maps, but legacy software is everywhere. :/
Your videos are brilliant Gary, you teach me with patronising me or me losing interested.
interest *
and he makes me feel emotionally secure
You just clearly answered several questions I have been asking for 10+ years. I thank you sir it means alot
You know it's a good video when the opening line is... It's simple, but it's not... Love it
Congratulations, this is the best explanation I've seen on the subject. Great video!
I've got a SanDisk 200gb in my Galaxy s4. Works like a charm. Picked it up a few months ago on Amazon for sale price of $60.
Bought the same for my z5, sadly with the marshmallows update they stripped the function to adopt the SD as internal. thankfully there I was able to adopt it but it is a little complicated and officially not supported
, as of a few days ago, for less than $20 & in a non-open market country (meaning, different from america), i was still able to get a 128gb micro sd sanDisk.
for $60 i'm now seeing deals for a half terabyte..
This video was really informative! Been a while since the last time i saw such a straightforward, simple and valuable video in just under 15 minutes! Great work!
update from the future! march 2019 the 1TB sdxc card has come out :P
You've only done half the job here
Read off and Write to these SDXC cards that have been reformatted and tell many if you get any failures.
Also, do you get full storage as shown on card?
If a 128GB thumbdrive were to be formatted as exFAT, will I be able to use just 32GB or the entire 128GB of it?
I lost 3 hours of footage because I didn't know my old camera didn't recognize exFAT from my 64Gb card and kept writing over older files. Very sad, but now I am improving my knowledge about that.

You're simply the best Gary.. I'm watching all your videos as if I'm in a lecture.. (y)
When you insert a fast (class 10 U1) micro SDHC card into an old device (it accepts SDHC) can it complain about the card being too fast ?
What I don't understand is why the Android phone manufacturers simply didn't go with an open format such as ext4 for the larger SD cards; it would have been *free* for them to do so. Ditto for other equipment manufacturers, such as TV, photocopiers, etc. The only roadblock would have been Windows' current inability to recognize this filesystem, but AFAIK, with the right driver added, Windows should be able to recognize it as well as exFAT.
Great info. *Thx* !!!!
I wonder what if the card formated as ext4, as all new Android device have ext4 support.
Is this an option formatting within Android OS?
Must have Extreme to 4K ultra not read 4K sizev
I love you Gary. Not only you are excelent at explaning how technology works. You also make this very entertaining.
+NinjaAlbertoSan no homo tho
great video, very informative.
does formatting the 128gb sd card to fat32 reduce the 128gb usage capacity of the card?
Excellent presentation. I like this guy's explanations of things. He keeps things simple.
Very nicely explained. Easy to understand. Now those formatting formats make some sense. Thanks Gary
This guy Gary, does some of the best android rewies. Awesome!
What do you mean the card worked on the Note 5? (around 9:20) There is no expandable storage on the Note5.
That's the most useful video I've seen in years. I couldn't read my 128gb card from my phone in my win XP PC. This explains everything. I hate the fact that everyone has to pay Microsoft though.
Thank You! I'm new at this, I didn't even know what format to my camera meant and I now know how easy it is to format thanks to you.
No, it's not just not to confuse customers. Samsung actually restricts the size of the cards you can put into their phones for some reason.

Didn't hear about the command prompt format when things go really wrong with the card or usb stick by not been recognised by any os.
Doesn't the maximum storage limit also depend on the processors data bus size? Or is it just for the RAM?
Hi Gary. Could you please tell me if there is a way to get a custom rom (especially cyanogenmod) for unsupported phones? I have a Chinese phone. Like are there any processor specific roms available? I'd really appreciate your response.
I seriously stayed through the whole video and now, i am a wise learned man. Peace.
Guru Gary does it again! Amazing video as usual.
but what if you pass that 32GB. does the R/W speed slows?
+orestislef Nope!
I meed in fat32...
+orestislef nope
"... Compression wrecks performance."
Depends which CPU you use. Input-Output is faster; smaller file sizes. Using a fast, multi-threaded CPU, makes things faster again.
*multi-threaded CPU*
...um...CPUs aren't "multi-threaded"...

I bought a 32gb microsdhc. for my camcorder made a video but when I install it into my phone there's no sound but sound when I play it on the camcorder I have a android Samsung prime so I can't send it anywhere cause no sound could you help me
So, you can only format it to FAT32 on a phone? I got the gyst of it early on, was waiting for you to show a link on were I can format the ExFAT to a FAT 32.
You can do it using built-in software in smartphones and windows.
Great stuff. A question though, are there 200 gigs or more SD xc cards available in the market?
+Ankit Kothari I think you can get 200GB at the moment, but I am sure the sizes will keep going up...
+Gary Sims yeah! it is available. very expensive though. Will the pricing be by the same norm? I mean will 200gb become cheap when there is 400gb available in the market?
I once owned a parrot bebop and if the video file size went over like 4gb or something the files would not transfer at all on to my Mac. I wonder if it was the android holding back or if I had used a Microsoft os if it would have worked. Either way, from the sound of it, I'd prefer to have a device and card that work with xfat based on my past issues.
One thing that I've noticed on my LG G3, is that the phone will recognise exFAT when it's booted up(Cloudy G3), but TWRP will only recognise FAT32.
Can you help? Why does my Samsung SkyPro wipe the micro SD card when I power down EVEN when the card has been unmounted first? Have not been able to find answer on Google.
MY Samsung MicroSD 256 GB does not take large files. For instance, instead of copying a large music file from my PC to micro SD with many albums in it, I had to do one album at a time. Even then, many times the PC would show that the files were being copied to the MicroSD, but when I opened it, the file was empty. It's very frustrating and time consuming.
Thanks Gary! Well Done! It is one thing to know this stuff, and quite another to present it in a meaningful way in a video. Awesome!
Gary how can your Note 5 recognise the Micro SD Card if HELLO it doesnt have a micro sd card slot?
Great tutorial but I now need HELP PLEASE. I have an android tv box the Minix Neo U9-H but wish to increase the (internal) storage a little with a micro sd card my help is please can you tell me what 32gb (fat32 I guess) make and model of card the box will accept preferably without having to mess about formatting it. I have just corrupted 2 scandisk extreme pro's 32gb and blown £40.00. TYIA.
So if I put a 2Tb SD card in my phone pre formated to FAT32 will I be able to use the full 2Tb space ( I mean the available space )?
What about the new PNY 512gb micro SD card... do I have to format that as FAT32 to make it run in a phone like a LG v40 which is rated at 2tb capacity? It seems like a stretch since there's a big difference between 512 and 32
What happens to the extra storage that is formatted in FAT32, ie., 128GB formatted in FAT32?
My Galaxy S4 can read NTFS file system with a custom kernel😀😀😀
+Dewang Patil But Ext4 and F2FS are significantly more performant / customizable.
+landwolf00 Ya but i just wanted to tell that android supports NTFS too
I wish I was exfat 😭
I once plugged in a normal USB hub connected to a power bank (just to power the HDD), a 2 TB NTFS HDD, mouse and keyboard and it all worked on the stock ROM of my S4. Though the screen broke later, so I sold it. I also just used Paragon for it. Now I have an S9+ with
Great Video and information, I agree with Jason K about how a graph would certainly expedite the knowledge crystallization.
I have never had any issues with swapping in higher capacity cards in my Motorola Droid2,, Droid4 and Wifeys SG5.
Until I upgrade my phone again I have been granted a temporary reprieve with the Droid Turbo (64GB and sans MicroSD slot).
Awesome video as always. Quick question, is there a W/R speed difference between the different file formats?
+Jules N. Yes there is, there are some performance reports out there... Google something like, "fat32 vs exfat speed"
I'm just a bit confused. If FAT32 functions with max file sizes of 4GB then how can you use a 128GB USB?
That is beyond the working range of FAT32. Shouldn't any device formatted in FAT32 be read as 4GB storages?
I've had bad luck with cards over 16Gbytes. They seem to be corrupted by the device. I've had two 32G cards corrupted to the point nothing could read them or even reformat them. With 16 and 8Gbyte cards the card has worked well. A few APK files got corrupted but the card remained usable. I've never tried any bigger than 32Gbytes. It seems the curruption is related to the battery running down the the point the device shuts down. When this keeps happening the card is damaged beyond formating eventually. Is there something I'm doing wrong or is it these powerdowns.
You can use diskpart to format SDXC as FAT32. The filesystem is the only difference between SDHC & SDXC.
I've read a lot on microSD card but listening to your history lessons on it was way better... Thanks... Now we know why Microsoft is so rich. Cheers!
I bought a mini usb style mini pc which runs on android its got a usb port so i put on a 128 gb mem stick and i also got a micro sd card at 16 gb both memory thing get read but not at the memory they are the stick reads at 11 mb and the sd reads at 3.5gb what can i do to get the full memory. Can you please advice. Do you think i should format it using the mini pc as originally i did it on a windows pc.
Many Thanks
I have a 32 gb card and I formated it with exfat because I have to save files larger than 4 gb but files seem to corrupt very ofter . I am using huawei honor 8 lite and it does support upto 128 according to huawei. Can it be something with the filesystem.....? Please explain......
@AndroidAuth sir, I had a usb storage of 8gb frm Sony.Once I formatd it in COMPUTER running Linux Os..afteron usb drive didn't work for me.Windows didn't detect that usb drive.. can u suggest a solution to recover back my pendrive to original working condition.
but formating a 64Gb to fat 32, you will lose access to some of the space right?
so there no technical advantage of FAT over ext4 or journal fs on sdcard?
I bought a brand new 2021 android radio and for sum dumb reason it wont read a flash drive larger that 32, is there anything thing i can do to circumvent this??
good vid, do you have a recomended tool for formatting?
I have a strange issue. 128GB Samsung Evo plus runs good on PC with exFAT (92R/65W). But on Samsung S20 (78R/35W). If the phone's uptime is more than 1Day then speed drops further to (22R/16W). Tried formatting inside the phone which makes it ext4 and it doesn't change anything. Yes speed increases a little bit but after 1Day same drop. I have a Android One device with SD Card support which doesn't have this issue. The android One device doesn't support exFAT though.
Moreover another SD Card with 16GB SanDisk Extreme FAT32 on S20 never drops in speed even with multiple days of uptime.
So for a device that doesn't recognise exFAT, if I reformat my 64GB to FAT32, will the device be able is access 64GB? Or is it limited to 32GB?
Would it work being formatted in Ext4?
Yes, and it does when you select "expand internal storage" in the phone's storage settings (note that doing this deletes all data currently on the card), well, either ext4 or f2fs by default.
Sadly there is no option to just normally use ext4 without rooting (at least wasn't on Android 8.1.0 where I tested), even if you would know you would never need to use the card in Windows. I think it's stupid that Android artificially limits what file systems you can use, even when there is support for a whole host of them in Android.
That was quite an informative video!! But had a query to make. Will putting a card bigger than 32 GB in a phone that officially supports only 32GB of external expandable storage affect its performance in any way? Like R/W speeds or lags?
It is all dependent on the Smartphone
For example my Samsung Galaxy A12 supports up to Micro SD Cards as big as 1 Terabyte
I had a 32 GB PNY Micro SD card in my Galaxy S4 and I even day I woke up and the phone acted as if I didn't have an SD card. I put it in an SD adapter and went to the computer and the computer didn't read it either. Nothing reads it!!!! Any ideas on what might of happened? or if there is a way to recover it?
can someone explain to me why on the older android systems writing to a USB flash drive via micro to USB female adapter was snappy and efficient. now however on Android marshmallow (what im using now. not sure about the latest ones) it literally takes several hours for a few movies. ive scoured the Internet with no understanding at all.
When I connect my Action Cam's Micro SD card to my Galaxy S7 using an OTG cable and reader, somehow different files get added to the Micro SD card automatically. Seems like some Android files or something. What are they? and can I stop them being added automatically?
Does android recognise SD cards formatted in ext3, ext4, or JFS? That would completely solve large SD cards and large files for me.
What would happen if I put a 64gb card in the Samsung S7, which I formatted on my computer in FAT32, would the card be returned to exFAT if I format it in my phone?
do you know anyway I could format a USB drive from a Android phone to set it up to Fat32? any app I could use on the phone
Why does the SD association define what filesystem I can put on my sdcard? Am I forbidden to put my own onto it? Do they license filesystems as "SD card compatible"?
Actually The original SD could support up to 4GB as well As there being SDHC 4GB cards. The SDHC format phased out the SD format while the 4GB SD theoretical maximum was reached. Also SDHC has a naturally higher transfer speed VS SD so that was another factor why you almost only saw 4GB SDHC cards.
