hey! my phone antenna lines which is connected to the middle frame was ripped and the bluetooth and wifi doesn't work, if I buy a replacement middle frame would that fix the issue?
It should work with a replacement...But this is a shit move from Samsung to put those lines on the frame,especially outside where you use a tool to open the back. It just happened to me now and i will have to do the same as you,buy a middle frame. The phone is not even mine but definetelly not buying a Samsung product...Apple neither nor i recomend any of the two.
I thought the back was made out of glass, but it turned out to be shiny plastic. Tbh I prefer it that way, since plastic doesn't shatter nor dent.
Ya it has its benefits
scratches like a mf though
@@dendethegrey I use mine with a case so it's protected it a lot, only has some slight scratching from all the dirt and stuff that got in between the phone and the case. Nothing major though, for 3 and a half years of use I think it still looks pretty good.
its still shatter and dent. its just not as bad as glass
This is easy compare to other phones, thank you sir
You're welcome, and yes its pretty easy. :)
This video is going to be my reference one day once I mod the phone's heat spreader to occupy most of the back and also swap out the thermal pads they have for copper shims and some thermal paste.
Good, easy to understand. I followed it ,and ,waaooh,I made it,thanks
bro I have a question. 1:00 what will happened if the untenna line are cutted off? this previous technician put a lot of black glue to it, when I try to open the back cover some of it sticks to the cover.
It will cause the antenna not to function properly, so won't give you the best signal.
@@PBKreviews so the signal won't completely gone right? its just weaken the signal
@@eddieazhar5185 I have the same problem
That extension ribbon is soooo pretty!
@yousef banat cook and tech diary its a half colored extension cable, I have never seen that before
@yousef banat cook and tech diary true, the frame is the most dinged up part of a phone, easily replaceable
@yousef banat cook and tech diary true, unless you are really skilled, just get a new battery. Its really not worth the risk
Thank you for the lesson.
You're welcome!
Does this phone get water damaged easily if it is fallen into water bucket for 15 seconds ? Or it can withstand and we can use that phone for long term ?
thanks for the video got my a31 lcd replacement.
No problem 👍
I have a device that fell into the water.
Now it works.
Glad you got it working. Just make sure once you clean out any liquid inside, you also brush off any corrosion from chips or connectors with a old tooth brush or similar brush to prevent any shorts in the future.
Very good

Hi, and thank you!
*I am using my Samsung Galaxy A31 to watch this and also my back is blue too*
Nice :)
Just one question: what is the correct type of glue to be used to close the cover, or what size and type of adhesive tape should be used? It certainly need to be removabel again with thermal treatment.
AND most important: where to buy it?
Thank you for your help !!
Hi, here are two links: www.ebay.com/itm/203131770722?hash=item2f4b98d762:g:oIIAAOSwO7dffXLm and www.ebay.com/itm/154787197779?hash=item240a093353:g:uvsAAOSwgfBgrl7E
B-7000 glue or 3M double tape...
I got this phone, the main rear camera is so blurry like it's out of focus all the time, is the sensor broken and I need to replace it?
The ultra wide and micro camera work fine
Might be, or maybe there is moisture or debris over the lens that needs cleaning.
what does the flex cable do ?(the one that have main bus and octa)
I have a samsung a31 and there is no screen response except the power and volume buttons... all the connector seems fine. But can you tell me the parts that relates to the screen?
Did you replace the screen? You might need to update the phone software to the latest software. I know without a working screen will be hard, you might need to use software on the computer and flash firmware onto the phone. Or you would need to use the previously broken screen if it works to software update the phone. If that doesn't fix it, then you might have a damaged connector for the screen on the main board etc.
Why it’s not working when close the cover with screws and when I remove the screws and remove the cover it starts again charging, please reply
Blz, me ajudou a abrir com segurança
Fun fact. All these phones use the same LCD. OPPO A11x / A11 / A8 / A5 (2020) / A9 (2020) / A31 (2020)
How do I take out SD card?
what do you mean? you use the sim ejector tool to eject the sim/memory card tray
@@PBKreviews i mean, my phones battery is dead and I cant charge it but I want to move my photos to a pc without buying extra parts. How do I do that. I found that I can buy a sd card reader.
do you guys have a flat back of Samsung A31?
what do you mean?
@@PBKreviews mine is like it doesn't have a flat back. It's like it has a bloated part, it's in the upper part of the cable after you plug out the battery cable the one that has "MAIN" word in it.
I bought an LCD, the phone went 2 months without Charging or anything cz it was dropped and turned out black the whole screen, After Changing it the Phone didn't turn on!!
Whme charged like a whole day, but nothing happened.
What is you take? You advice on where to check, because the tech tried another 2 LCDs and didn't work, He checked the battery which has Power, But still can't turn on.
Advice Me Please.
Maybe the display connector or a chip on the board got damaged from the fall, not sure.
I need a video on how to replace/ fix the connection of the power and the volume.
The connector for the power button and volume keys is on the back housing. That back housing needs to be screwed down properly so that flex cable touches the contacts on the main board to give it a connection. So if you're back housing is lifted up say from a drop or the screws are loose etc, it can cause an issue with it working.
My board is heating up wickedly and the speaker doesn't work. Eep. I already replaced the charging port board and the ribbon cable has a jumper on it. I think it's time to let go. I already paid someone $140 to try and fix it.
Can i use that blue wire cable 1:43 (antenna flex) on galaxy a7 2016?
Im not sure if lengths are the same but if its long enough, you should be able to use that coaxial cable.
@@PBKreviews 👍👍
mine dosent charge how can i understand if its a problem of the motherboard or only thew charging port ?
if the batteri is charged the phon work propretly
Not sure you would have to test it out by replacing the charging port/sub board to see if it fixes the problem or not.
Fun fact: Im watching with Samsung A31 xD
Nice :)
Team A31 for the win! 😁
Is it waterproof?
No, its not waterproof but does have some water resistant features like gaskets around connectors and some rubber gaskets around components but probably just minor splash proof. Would probably not survive being dunked into water.
@@PBKreviews ok thanks
@@Kajetanpsikuta you're welcome
When i touch the back of my A31 i feel the shape of the battery. Is that normal? Or my battery is bloating
Bad! What happened with that in the end?
Bro I have my phone's back a little lifted from the power button side.can you tell what's happening to my phone
Hi, it can be two things. Either you dropped the phone and the housing clip has come undone (which you can press down and click back into place) or the battery is bloating and going bad and its pushing the housing outward.
Is there any parts that cools the phone?
Just has some graphite film to transfer heat but no special cooling
Nice
Thanks!
@@PBKreviews What's a good adhesive should i use on the back plate? Also is that a guitar pick your using? Thank you.
I don't know why there are videos where they show that the samsung galaxy A31 cell phone is submersible to water and in the user manual they prohibit it
Reason might be that it may be splash proof but there are no official ip ratings obtained by the manufacturer so the manufacturer can't advertise it as being water resistant because it won't be allowed to unless it paid for special testing to obtain ip ratings.
@@PBKreviews you certainly can't submerge in water. Mine fell into a storm water drain and now all it does is constantly reboot. I did take it to a repair shop, but they made it worse. now the touch screen doesn't work either :( They stated it cannot be repaired!

저 플라스틱 뒷면의 도색은 벗길수 있습니까?
Hi, I'm not sure since its been a while since I did this video. Some backplates which are plastic have a laminate print layer over it which can be peeled off but usually plastic backs have the paint directly applied to the plastic so its not something that can be peeled off. However on most glass backplates, its almost always laminate layers that can be peeled off.
Sir Samsung a31 sf 128 main bord Price websites name
how thick is the "shell" of a samsung A31
I'm not sure, I don't have it with me anymore to measure.
My phone dropped 5 feet on the hard ground and I am so worried that it might have an internal damage
As long as its working, you should be fine :)
Can it carge wirellesly?
It doesn't come with wireless charging as a feature for this phone. You would need to use a third party wireless charging coil which connects to your phone via the charger port if you really wanted to use wireless charging. Sort of defeats the purpose though.
If i replace the screen of my samsung a31, do i need to replace the lcd too? Or it was built with the screen?
glass and screen should be one piece, you can't replace just the glass.
In your opinion, is this phone durable ? Not easily bendable?
I am it's durable but not as strong as phones with a one piece aluminum frame which are stronger and more reinforced.

Fun fact im watching on my samsung a31 and it needed life support

Одно не пойму, зачем отсоединял камеры?
Samsung galaxy A series is 💯 % better than J series

I have this phone but its not charge :(
Can be a bad charger port or battery.
@@PBKreviews I too have this problem. Took to two different phone shops and they said it may be a motherboard problem as the charging port, ribbon cables and battery were fine and tested with a new charge chip set, ribbons etc. but still wouldn't charge. So a disrupted connection somewhere from the charging part to the motherboard. Both shops didn't specialize in Samsung android motherboards to replace or repair, so they gave back the phone free of charge.
