Samsung A71 Black Screen of Death - Samsung Galaxy A71 Questions & Answers

Hi I have a problem with this phone and it started a month after I updated it to Android 12. Everything goes well at first but suddenly my screen went black but the phone is working because I can hear the sound when I turn off my phone. So I tried ALL the solution in youtube, it works but after a few days the problem is still occur. I tried factory reset, wiping data and cache. One day I decided to downgrade my phone to the last update of Android 11. It works! but sadly after a few days the black screen is on the run again. Is there any way to fix this guys? I certainly didn't drop it or accidentally squeeze it. Help me guys please!!!

xperia screen stopped working

hey
i have been using my xperia for 7 months now, but 2 days ago my screen just stopped working. the phone still works, only the screen doesn't display anything. i know its working because my alarm still goes off. and it vibrates when i start it up. i tried soft reseting, hard reset, update to a different custom rom. so im kinda stuck here, hehe.
any help?
thnx
Hi.
Realise this is quite an old thread but, incase you haven't found a fix; this has happened to my X1 twice now. The first time, I sent it off repair but forgot to put the ROM back to the factory one so they told me it wasn't covered. Anyway, I got it back and to my delight...it just worked!
In summary, the fix for me has been to leave the battery out the phone for a long time. On the second occasion it was about a week before it started working again but it did work. Hope you got yours sorted.

[Q] Phone powers off and resets

Hello lads! The last few days I have been trying to fix a huge problem with my Galaxy S4 i9505. I had been using the Google 4.4 rom for almost a month without any problem. One day, when my phone was low on battery it shutted down and I plugged it in my charger to power it on again. When it turned on I was prompted to the screen you see when you use the 4.4 rom for the first time. I had all my apps but everything was resetted. Every setting, all the app data, messages, etc. I thought this was a one time thing so I used about an hour to get everything back to normal again. Then the next day, same happened again. Phone turned off because of low battery, and everything was reset. I tried to google it but with no luck, so I did a factory reset and flashed the newest Google rom (4.4.2) with a new kernel called Ktoonsez. Got everything back to normal again and used my phone for a couple of hours before it just suddenly shutted down once again, but this time with almost full battery. When i tried to turn it on I was stuck on the Google loading animation and had to reflash 4.4.2. It turned back on and this time I decided to let the phone stay stock to see if any of my problems was caused of my apps or settings. It lasted for 2-3 days before the same thing happened again... I tried to flash different modems, other roms and firmwares but nothing have helped so far. I am also prompted with a message each time I turn the phone on which tells me that com.android.phone has stopped working. I have tried several factory resets, wiped dalvik, wiped cache, but still has the same problem... I have now given up trying and wonder if anyone of you know what I can do to fix the problem? Any tip is much appreciated and I hope to hear from you! Thanks!
edit: figured out I posted this is the wrong forum as this is for s4 active and i have a i9505. Sorry! Anyway, please comment if you know how to fix it. Thanks!

The smartwatch turn off in version 1.5 and 2.

First of all, I want to apologize for my English.
I bought the LG whatch R second hand and at first it went perfectly, But then in an update (still in 1.5) the smartwatch would start to shut down continuously, if I gave it to start it started but did not start the system and it was shut down again, Until after some time could not re-ignite and have a use (for a short period of time).
With the update to version 2 the problem persists and I no longer know what else to do. I have returned to version 1.5 in a tutorial of this forum but the problem persists, I do not know if it is a kernel problem or that, but I no longer know what to do with the smartwatch, since it is impossible to enjoy it and it goes out to Little use it.
Someone knows how to solve this problem. And many thanks for your attention.
Hello, I recently had a similar problem after downgrade to 1.5.
Whenever I got the update to 2.0, I restarted my watch and when it switched on, the display was black in about 2 minutes and I had to turn it on again, this was repeated 2-3 times. Now I've done a full wipe and disabled update to 2.0, so I'll see if it's okay?

Jumping Screen After Nougat

Hi all,
I am completely running out of things to try and do now.
After installing Android 7 on my Note 5 I had the strangest issue that i in general have never seen on a phone. The screen is simply black (which isnt that strange) and the phone is fully functional. Bare with me, after reseting it multiple times so it would finally come on the screen goes crazy and turns goes into so many colours (if it turns on that is). Its either that or jumps all around the phone, quite literally it glitches out completely. Its like one of those virus cut scenes you see in movies, it goes different colours, glitches out, jumps around and completely misformats.
From the beginning i knew this was not a broken screen.
So far i have tried.
1. Factory reseting the phone. That gave me about 5 minutes of normal use until i locked the phone and it wouldnt unlock again.
2. Factrory reseting multiple times... again to no avail, it would work for short periods of time and glitch out again.
3. Reflashing stock Android 7 in Odin. - No avail.
4. Flashing Dr.Kretans Rom... worked for 1 day which made me so happy and think that the problem was solved but then the same problem persisted.
5. Installing Arters Kernel.. (arter97-kernel-n920cig-22.0) Nothing... literally did that today and still NOTHING
6. Re partitioning. Quickest process and no avail.
In more detail, if the phone does sucessfully boot, and bare in mind sometimes it takes more than 2 hours to get ANYTHING on the screen (including recovery which doesnt boot up either until the initial apperance of something on the screen)
I tried taking the phone to a phone shop before doing anything myself and since in England this phone was never released theyre refusing to touch it. I tried calling samsung and they dont want to do anything either cause its not a UK variant.
Could someone please tell me anything else i can try. I feel like im totally running out of options here.
My phone details are as follow
Galaxy Note 5
SM-920I Singapore Singtel Variant
Running on 6.01 (i downgraded from Kretan)
And the kernel is the one previously mentioned v.22.0
I would appreciate anyone's help or suggestions so much at this point. All these problems started since the 7.0 update a few weeks back :/
Oh its also running TWRP recovery (arter97-recovery-n920cig-22.0-twrp_3.0.2-0.tar)

Self Restart

I have got my Asus ROG Phone II for about 8 months and I have recently got some problems with the software. The phone suddenly turns off on it's own, when I am using it and stucks at the restarting process with Asus Logo and the loading bar on the lower side but doesn't open, even if I wait for a full whole hour. I have to press volume down + power off button to make it work again. I wanted to ask if any of you guys have got the same problem, or any clues how to solve it?
Well I had rooted my phone after a month of it's use and unrooted it. For about 2 Months before, my charging port stopped working and Asus Service Center fixed it, and I guess they somehow flashed my Phone, as I not don't have to download and install the new firmware. It was good in a way but I feel it is getting some lag during the use of certain apps and the problem which I mentioned earlier. I would be thankful and grateful for your replies.

Don't know what the problem is, but you've posted this in the wrong section!
I think I am in a similar situation. My phone's problem is that it kind of crash while booting up (stange lines shows on the screen like some glitch) , it doesnt boot up normally and it loops 3 to 4 times until it's left on a black screen. I am not sure of its status at this point for it is not responsive even to force restart (Vol down + Power) but it does work only once in a couple of minutes and proceeds to bootloop and back again to the black screen. I haven't rooted it but i did flash it from CN to WW which was successful and was using it perfectly for 4 months up until this situation. I dont know what exactly is the problem. Can anyone help me?
Same with me bro... Mines already bricked because of flashing it to the original version
Same here
