Hello,
I'm posting this for a friend, because his phone is "dead" and he is unable to post himself.
Earlier this year he brought a Galaxy SII from a second-hand phone shop, and it's worked fine up until now. He updated the ROM to the official 4.1.2 and since then it's had issues connecting to his home WiFi (unrelated, but it lead me to suspect the ROM) but it connects everywhere else. Then yesterday his phone just went blank and turned on again - the boot sound played at the touch buttons lit up for a moment and then faded as with a normal boot. But the screen was blank apart from several white spots, and a load of coloured pixels. I saw it myself today, and the colour of the pixels is random, although usually red or green, and the phone gets incredibly hot about a minute after turning on.
Is this a ROM fault, or could there be something more serious to it?
Just a shot in the dark, as I've never owned a Samsung, but could it be the "sudden death" bug that they allegedly have?
Thanks
Does it go to recovery? Factory reset. If not does it go to download mode?

I'm not sure - I think I managed to get it into the bootloader, but there's no way to tell because there is nothing on the screen but the white dots and random pixels. All I did notice was that when I removed the battery and turned it on again even more pixels appeared. We only went by the sound and touch lights, so it appeared to boot, but we don't even know if it switched straight off again

you are not sure ? did you try to go into recovery or download mode ? shutdown the phone first
Recovery = Volume up button + Home button + Power button
Download mode = Volume down button + Home button + Power button
Press vol+and home button and power button till it boots to recovery. Keep them all pressed down till it boots. If not try vol- home and power till it boots to download mode. Has he dropped it?

We tried that, and the touch lights came on but with no boot sound. The screen didn't change, just white dots and pixels, but it was working fine the day before.

Tried both, the screen just did the same thing and the phone got very hot very fast, and he said he hasn't dropped it at all, but that someone in his family may have, he's not totally sure because nobody admitted to using his phone.
Screen is prob broken. Pixels on it..not good. No recovery or download mode..really bad. For it too get really hot really fast may be a mb problem. Send it to service centre

Okay, thank you! He tried calling them and getting a quote, but the guy on the other end didn't seem to know what to do, and the man who owned the shop he brought it from offered to repair it, but for almost double what it cost him to buy the phone.
Thank you!
No problem mate. Get a second hand one. Prob be cheaper to do that now the s4 is out. Mb cost alot.

please remove the battery for like 10 minutes, wait a little bit, then try to go into recovery or download mode,
if that doesn't work, try this:
1.Press the key combination for recovery
2.Samsung logo appears - hold the buttons pressed.
3.Prompt disappears shortly - you still hold the buttons.
4.Samsung logo appears again - hold the buttons still pressed.
5.Count to 3 & let go, dont press the buttons anymore.
After 1 - 2 sec farther the Samsung logo disappears and the recovery starts maybe, i did that on my old i9100

Thank you, but that hasn't had any effect. Still a blank screen with white dots and thousands of coloured pixels. Thank you for all of your help though!
I'm having a really strange issue with my gear fit:
1. Screen is black
2. Screen responds to touch(!) - I unpair the device and pair it again, when i press the left(top) part of the screen (confirmation button) it stops vibrating...
3. I am able to turn it off and on but the screen is still black (Samsung logo does not appear)
4. Bluetooth works fine
5. Kies3 also recognizes the device
6. It happened randomly a few times - the screen turned on and was responsive to touch but when i try to do anything it freezes and goes black again. I noticed that I can even change the wallpaper and clock through the Gear Fit Manager. I thought that it could be just the screen issue but I've never dropped it and as I mentioned - it responds to touch.
This problem appeared out of nowhere - I've left the watch (turned off) for a month on my desk, the battery was at 40% today, tried to turn it on and...
Due to the screen failure I cannot put it in the download/recovery mode. Is there a way to do it with screen off?
I know it's stating the obvious but have you done a full reset on it? (Hold the button down, a good 8 seconds, until it forces it to reboot)

Just my 2 cents,I had to hold it down more like 20 seconds, way more than seems logical.
From my Galaxy Note 2
Has there been an answer to this because I've been having the same issue with mine for about 4 months. As stated before, it turns on but screen stays blank but I know it's working because it vibrates after I turn it on. Mine is a international one.
possibly a screen defekt? was the same thing with my when i rip it apart
I picked up my v10 (LG H901 unlocked) and tried unlocking, the screen was completely dimmed out. I could hear notification sounds and had the haptic feedback when unlocking with fingerprint but nothing could be seen. I took out the battery restarted the phone and the screen booted up into the home screen but dimmed out completely again after barely 3 secs. It's continued till now, I hear notification sounds, the vibrations work but the screen is completely blacked out.
Taking out the battery and reinserting starts the phone normally but goes blacked out again after it loads.
I'm on Android 7.0. Help pls

Power off the phone...hold down the volume down and power buttons at the same time....when you see the lg screen appear briefly (1 second) release the power button while keeping the vol down pressed..then re-press the power button....all this in the end should boot you into recovery...it will ask you a couple of scary questions which you can say yes or no to....the bottom line is this...if you can see fine in recovery then you've set the brightness way to low and/or installed an app that's done that to you in your ROM. If recovery is to dark to read then it's a physical issue with your device. About the only thing that's gonna undo the rom issue if it's that is a factory reset (which you can do from recovery). If you were using auto brightness then make sure when you get back into your rom that you disable it until you can figure out what you did that caused it to get so dark you can't read it.

Thanks for the response.
I have the same problem. Did you find any solution?
After splash screen, screen blank but phone sinks with BT & capacitive lights active
Today I tried to update my phone to the newest firmware (I think it was .210, but I know it was from August 5th on firmware finder...I know its a long time to wait to update, but I started a new job, moved to a new city, etc. so things have been super crazy). Unfortunately, after flashing with EMUI Flasher, the phone rebooted and then got an update failure. I restarted the phone and waited but the screen was black. However, my smart band paired and if I press the power button, the capacitive button lights turn on, but the screen is blank/black. I have tried rebooting, both regularly holding power for 20 seconds as well as holding the power key with volume up and then volume down. I can reboot into a recovery of sorts and tried to wipe cache and restart, as well as boot into safe mode, but both result in the black screen from before. I can also boot into fastboot, but don't know what I could do to fix this.
Any advice as to how I can save my phone would be really appreciated. I'm really hoping I don't have to wipe the phone.
Please help me!
Description
Sometimes, apparently in a random manner, after a period of time being idle (in my pocket or on the table) the phone becomes unresponsive to any inputs (power button, fingerprint reader) and the screen stays black.
Symptoms
Black screen, no response to input on physical buttons.
Only one way to get out of this is, hard reset using volume up and power which will eventually reboot, but it'll give me Sony logo then a black screen with white wrench triangle then powers off then on again and directly to boot animation then it's on and working again.
Any ideas why it keep doing this ?
