What ??

When phone boots up it gets as far as the android 'welcome - lets get started' screen. The touch screen is unresponsive so i can't select 'lets get stated' the after a few seconds it reboots going into same cycle.
Vodafone said it was the screen however after a replacement screen it is still not resolved. I've tried software fix through phone pc companion but no luck.
Vodafone won't look at it again so I'm stuck with it.
I just wondered if anyone had a similar problem and if it easy a fault with a small component that could easily be replaced.

You should send it to Sony, but you will pay for the repair...

Why is it not under warranty with sony?

S6 Freeze/bootloop out of the blue

So had this phone for a while now and no problems, been running nougat for the past few months, this morning took my phone off charge and placed in pocket. A bit later I checked my phone, it was not responsive a black screen, did a hard reset does the samsung logo then gets stuck either flashing blue or pink. So leave it until I get home, flash latest nougat with odin installs fine, reboots and does same thing freezes at boot samsung flashing blue. Flash it again and now its froze after its said erasing...
I think something has failed hardware wise, any others had this issue?.

Just install "CPU awake" from play store, this will help you keep the device working, this problem is very common in each & every Samsung flagship, starts after 2 year use(won't ever buy a Samsung flagship again), no fix for it, if you don't believe me, check Evey flagship forum q/a section.

That app is useless, in that case completly useless. That app just won't allow CPU's get to deep sleep. But in him case that looks like just next S6 who get hardware broken from unknown reasons

Really? I have a note 4 , exactly same problem, that app gave it new life & not just mine, many note 4 users are using it who are facing the same problem, so, next time instead of just posting nonsense, do some research.

He even cannot turn on the phone, maximum what he can see is SAMSUNG logo so what the **** you are talking about turning on some app on working system?

That's a nand problem, if the device is cooled (I hold mine in front of AC for 5min.), that will help it to turn on & once it's on, install the app & it will work fine but it shouldn't be allowed to shutdown or it has to be cooled down again, it's not a new problem, thousands of Samsung mobiles which ship with faulty nand face the exact same problem, I know it sounds silly, it is what it is & it works(for thousands users)

rifek4 said:
Never before heard bullshits like that. Can you give some link to any information which will confirm that what you told so that a CPU Awake app will fix broken Samsung device? Please about it.
P.S.
I could'nt find anything about it :laugh:

Enough with your bull****, here, take a look...
https://forum.xda-developers.com/note-4/help/note-4-freezing-restarting-t3348821
Read it, on almost every page someone recommended using cpuwake, it's not my problem that you are such a fool who instead of trying to help someone with some advice, would just bash other people who have faced similar issues & maybe know the solution. You can go **** yourself for all I care.

Rishi is correct about cpu awake on the Note 4. It is commonly viewed as a means of extending the life of the Note 4 but eventually the phone will fail.

S7 non responsive screen but leds and charges ok

Hi I have just bought an s7 which turned out to be a Korean G930L but I cant get any response out if it apart from the 2 bottom leds and and the blue one. No response from trying to get into recovery or download mode, basically a black screen though it does vibrate on what i think is start up. It is found by pc and Odin and charges ok, I can tell as I can see properties on pc. But no other response. Is it possible that the previous owner tried to root it using non korean rom or TWRP? Any advice on how to fix either getting TWRP on or screen to light up. I am sorry for being so vague I have pulled it apart and checked all of the connections, screen, motherboard etc but nothing. Odin sees the phone but I am not sure if I am in Download mode so wont flash, as cant see screen.
Or chuck it out or put back on eBay.

Your phone's display screen has a problem , sadly you have to replace the display screen. Go to the nearest samsung service center.

Thanks it isnt worth it I will just sell it on ebay. I have been able to get to some of the screens [though still black] as it talks to me in Korean and the screen is giving haptic feedback so aspects of it are alive still. I am wondering now if someone has tried to ROOT it and semi bricked it or turned off the display internally. The other night night no matter what I pushed it vibrated and answered me with the same korean statement. I am trying to get into Recovery Mode without a screen and flash it without a screen but proving frustrating, maybe samsung dealer can reflash it with needing a screen.

It's not a software issue, there must be water damage or display is broken/went off for some other reason.
I had this same issue with my note 5, I was able to hear everything, touch key and notification lights were on too, that time my note 5 was accidentally dropped by me. So 99% your display is broken. Simply go to service center and get a quote, but display will cost same as used s7. Try to get after market screen.

ok thanks for the advice, i will head to them after the xmas break

Froze and then won't boot. Is it dead? :(

Hey guys.
I was browsing the web using Chrome on my Galaxy S6, until it suddenly completely froze, a few seconds later white LED went on while the display was on on the frozen, halfway loaded Chrome page. I did soft reset (volume down + power button), the screen went black with only the white LED being on. Upon retrying sometimes it would display the Samsung logo (static, not animating and not progressing) and would be stuck there. I allowed the battery to die, plugged it in and I had a fully functional charging animation. After it reached 20% I tried to turn it on but now nothing is happening at all - just black screen, LED is off no matter what. I tried power + volume up + menu and nothing is happening, just black screen. Charging does nothing now, and when I plug it into my PC the PC does nothing (as if nothing was connected, not even unknown device).
Is there anything at all that I can do? What could this be?
Additional info:
It's the international version, running it's official software, I never tinkered with it in any way. I have no idea what is the bootloader status but it was not altered from factory (it came from Orange Europe).
I replaced the battery last year at an official Samsung service center and never had any prior problems.
I would really appreciate your help, guys, as I have no idea whether the phone's time has come and there's nothing I can do (and should go and purchase an S7 or something), or if there's anything that I can still try, or maybe it's some trivial problem?

Try disconnection and re connecting the battery. It may be a hard job but that's the only thing I can think off. If that doesn't you may have to replace the logic board

Thank you. Since I'm not savvy enough in regards to opening it up and re-sealing (and don't have any of the necessary tools), I guess I'd have to do that at a service centre, and considering it might not even fix a thing, do you think it's worth risking and spending money on? My alternative is getting a used S7 for $220, and any cash I pour into fixing this one could go into the other phone instead.

Nope, get the S7. Samsung quoted way too much to fix my S6 as it needed a new logic board. They said it you may as well buy a new phone

Even if you wanted to repair the s6 it would be too much work and you could risk breaking something else. I saw a guide on YouTube and you have to remove the screen assembly to get to the logic board. Older galaxy devices aren't like that and are much easier to repair

Need help with "dead" blackscreen

When I turn on phone it shows boot logo, but then black screen appears. Sound and touch work but screen is "dead" (only when system is running).

hardware problem, replacement of the motherboard or display
Is there water in the device?
if not, did you install modifications in the system (gsi, custom firmware, custom boot, etc.)?
(Google Translate Russian>>English)

Привет. No, It just suddenly went black after reboot¿. For no reason.

flash new rom if not fixed you should change your display hardware

Everyone who had this problem either got wet (the child licked the phone, etc.), or dropped it
There are a lot of such killed devices in Russia, and almost all of them had water. They were helped by the replacement of the screen

That sounds weird to replace screen if it works. Recovery, boot screen etc show up with no problem but when soft is running it turns black. I've been trying hard reset, reinstalling software etc but It doesn't work. Even guy at local repair service can't do anything about it.

only replacing the display, this is a hardware problem, it cannot be solved by software.
for those who had such a problem, only a replacement helped them (in some cases, it only helped to replace the motherboard)

me too
I have the same problem with a customer's a51, it's very strange, I did hard reset, flashed a new firmware, but when it turns on it stays on the boot logo and then when it enters the os it remains the boot logo and if I press the lock screen button remains black, I also activated the voice assistant for the blind and it actually says "screen off" "screen on" etc ...

For those who have this problem, one of my family member A51 was dropped in water and had this problem. I tested every software reset factory and reinstalling official ROM. but the screen went off but voice assistant could be heard. screen worked properly in recovery mode. I gave it to unofficial repair center. after a lot of tests they said mainboard must be changed and LCD had critical issue. both of them must be replaced. Somebody say that Samsung mobile quality is better than Xiaomi !! )
