SO Sunday morning I wake up and my phone has been on charge all night, its 100%, I unplug the phone and about 10 minutes later its very hot and at around 60% battery. So to stop this I go to turn it off and start seeing these red "bubbles" under the screen like water but its the LEDs turning red. I have never dropped the phone or put it under water. Its a hot day as it is and about 5 hours later I turn the phone back on and its fine for around 15 minutes watching youtube videos, it then starts flashing black, like the whole screen shuts off for half a second and comes back, still sound playing, about 5 minutes later the phone starts glitching out and the pixels on the right hand side start turning red (no link) like so. Then the phone starts jumping between that and this ( no link ) which happened for around a minute and since then the phone screen is just black and doesnt display anything but the phone is still active and had feedback on the screen such as touch vibrations. Really want to know whats happened and why if anyone can help
Probably a hardware defect that will be covered under warranty. But possibly a software problem that's causing the cpu and gpu to run really hot. You can try booting into safe mode to see if that makes a difference:
Shut the phone off and let it cool down.
Boot into safe mode: https://www.google.com/search?q=gal...rome..69i57.3932j0j7&sourceid=chrome&ie=UTF-8
Use the phone for a while, and see if the problem reoccurs. (Your 3rd party apps will be disabled, so you won't be able to use them, but you can do other things.)
If this seems to solve the problem, delete any recently installed apps, or factory reset the phone, and see if the problem stays resolved. If so, add your apps back in a few at a time, so if the problem reoccurs you'll have an idea what caused it.
If none of this solves the issue, it's a hardware problem.
My wife had EXACT same problem. Backup everything while you can as my wife's phone died few hours later. (no display at ALL - digitizer was working fine though - so could shut down, etc). Symptom also was that when you reboot, it will display the boot up screen just fine, but as soon as all white screen was able to display, display will just die, etc. Pressing power button repeatedly would eventually turn on the screen but color would be off and simmering, etc.

History:
Phone was warrantied after it locked up during KK update. LG Canada replaced the board.
Current:
Had it for a day, loaded everything back on (apps, photos, contacts etc..) and in the middle of uploading my backed-up videos the screen goes black. I can hear the tap/swipe noises when I touch the screen, but nothing brings back the screen. I try turning off/restart, holding the power button for 20+ secs, and confirming that it's not just in lockscreen. When turned back on, I can hear the LG splashscreen but the screen is still black.
Later that evening, I planned to set the phone to charge for the night and see if it was a battery issue. With the phone completely shut down, I plugged in the micro-USB quick charge and to my amazement the charging battery graphic appeared. I powered the phone up and everything was fine.
It has happened a few times, and all around when the battery reaches the half-charge level.
Anyone else experience this? Any way I can troubleshoot?
Should I just warranty the phone again - or get it replaced?
Thanks.
I'm having the same problem right now
Did you figured out what was the problem??
Do you have any solution?
Tonight, my turbo 2 started acting up. I pulled it out to make a call, and the top 1/2 inch of my screen was flickering purple. That went away after about an hour, but then the whole screen went black and unresponsive. After trying to shut it off and reboot for a bit, it just randomly started working again. Full battery. Everything works, except the top 1/2 inch of display is completely black, every now and then, it will be green. If the phone sleeps, even for a second, it won't come back on, for about an hour, then it will randomly start working again. Never got wet, or dropped. Any body had an issue like this?
There's a known issue with a green line on the screen, I believe the speculation is a bad batch of screens got out, you're gonna have to exchange it for a new phone.
I am currently having this same issue. Going to VZ today to see about resolving it, as really hard to do anything when its doing that. Top 1/2 or more of the screen is flickering purple, then the screen will not let you turn up the brightness, all programing in the back works, just a LED issue. Restarted and same thing, let it charge Off all night, and back to normal after a few minutes using it. Very odd, not sure what is going on.
I have a similar issue, and I am trying to recover some data from mine. It seems booting into bootloader mode and using ADB yields nothing
I also cannot use MTP, as when I plug my phone in it's not in MTP mode for some reason, and i Can't see how to turn it on (screen is black). Digitizer still works. Does anyone have any suggestions? Can someone here maybe take a video of themselves plugging the phone in via USB and then selecting MTP on the phone? perhaps I can do it blindly...
Really don't want to give this phone back to vz until I get my data off of it.
About eight hours of pissing and moaning and I finally figured out:
Using the replacement phone, I just mimicked every movement on the one with the dead screen. I hit the "cast" button on the notifications panel and casted the screen to my chromecast, which in turn allowed me to set up MTP mode and/or anything else I wanted.
Cheers, hope this helps someone
My S4 keeps rebooting and I think it's a hardware issue but I do not know exactly which part might be the problem. It did slip out of my hand and dropped on my desk (not that hard) but it did not show these symptoms until a few days later so I'm not exactly sure if the drop is the cause of this issue.
It does not necessarily reboot at the Samsung boot screen all the time. It sometimes reboots at the Samsung logo screen or after 1-2 mins at the home screen. It has also frozen at the Download mode screen, so I don't think it's an OS issue or a bad app.
I've already tried a different battery (new one I just bought recently) and I don't think it's a Power button issue because as I initially thought it could be problem with the Power button so I had removed it and had planned to solder a new one. Without a power button, it still freezes/reboots. I did notice sometimes after it has frozen, when I try to charge it nothing happens (no red light) but once I pull the battery out and put it back in, it charges again. Also sometimes when it freezes, I have lines on the screen, but once I take out the battery and restart, it's ok.
I would hazard a guess that the LCD or digitizer might be the problem (but I don't to waste the money if it ends not being that)? The only reason why I say this, is because I managed to get to the home screen and enabled USB mode (screen was off after) and it did not reboot or freeze for more than 5 minutes (longest so far) until turned on the screen and seconds later it rebooted.
Can anyone advise whether it is likely the LCD that is the problem? I plan to get a new phone soon but wouldn't mind fixing this if the parts are fairly cheap.
Any help would be greatly appreciated!
Answer me this: If your computer freezes, would you suspect the screen? I mean, the screen's sole purpose is to display stuff. So why would the screen cause the computer to freeze?
Same story, different device.
Your issue will most probably require a motherboard replacement, as I don't think you can find the faulty parts separately. I suspect either CPU or GPU.
Hi, I have a Moto G4 XT1621 bought almost 6 months ago. Never had any type of problem, but two days ago I woke up, saw the hour just fine, and five minutes later I grabbed it to check notifications, and it was dead. The only sign of life the phone gave me was the blinking of the charging LED and the phone vibrating randomly when I pressed the power button. That night, the phone turned on, but the screen was always black, no backlight. I heard the boot up animation sound (the classic "HELLO MOTO!!!"), but the screen wasn't turning on.
Thinking it was a software failure, I've flashed the stock rom via fastboot (the phone connects in bootloader mode, but I can't see the bootloader screen), but the problem was the same: I can hear the boot up sound, and if right after the phone boots up I press the power button, I can hear the lock sound about 5 or 6 times, but apparently it turns off itself.
Sometimes, it can't boot properly; the boot up sound is cut before it ends, mainly in "HELLO MO...".
I really need help, I've tried everything: leave it charging for hours, tried a major amperage charger, pressing the power button + vol down for 2, 3 and for 5 minutes, disassembling it and reconnecting the battery, tried to turn it on without the battery, flash stock ROM, all kinds of wipes, etc.
The phone hasn't suffered from water damage, I didn't dropped it or anything like that. The screen connections nor the motherboard connectors does not presents any damage.
Any help is welcome .
PD: Sorry for any misspelling, english isn't my main language :silly:.
Could have been the screen or the GPU

It seems weird because the phone didn't have any issues, it just turned off and bye bye. I'm running out of options
Edit: needless to say that the phone don't stay that much powered on (5 seconds aprox. for the sound that the lock screen do), so I don't think this is a screen problem. If it was a screen failure, the phone will stay on.
Bad/good news?
Almost five minutes ago, I noticed that the screen on the phone is on, but slightly visible, almost impossible to see: you have to be in a fully darked room, and its backlight it's on, but it shows no sign of letters on the bootloader or boot animation whatsoever, it's just backlight.
Any ideas of what could it be? I'm almost decided that I need a screen replacement, but any ideas will be welcomed.
Awhile back I dropped my phone & cracked the screen. It worked fine for months then the screen began flickering and within a few weeks began turning off frequently (even though the phone was on and functioning). It became unusable and I had the screen professionally replaced. It worked fine for several months, now is malfunctioning again. If I charge the phone, the screen works fine while the phone is fully charged and plugged into the charger. It will continue to work for a while if I unplug the charger, but once my battery level gets down toward 90% the screen starts flickering, then soon begins going black when I try to use it. It may turn on for a second or two, but the screen goes black almost immediately. The 'always on' clock and date work all the time. Like before, the phone still works even though the screen won't stay on. Does anyone have any suggestions? I haven't dropped the phone or damaged the new screen to account for it, and I wonder if there is some other problem that might be the cause.
