Good day XDA peeps! I have a problem with my S6e+. Sometimes the screen just randomly shuts off but I can still use the touchscreen. Example is if someone's calling me i will just swipe the screen to the right even if I cannot see anything because good thing I got the commands memorize in my head. It does that randomly.
It started doing this problem when I was using the fast charger. I noticed that when using fast charger my screen is just black, but I can use the touchscreen. It will light up around 80% battery (maybe when my phone is not hot anymore from charging). But when I untick the fast charging option, it doesn't make my screen black. But now, the problem is getting worse and worse. It sometimes shut off by itself. I need to try around 10-20 times by pressing the power button until it shows me the display. I've tried doing a clean install in Odin by flashing a stock MM 6.0.1 but the problem still persists.
What could be the problem of my phone? Any help would be appreciated. Thanks!
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.
Today my V20 H910 died on me in a rather strange way.
I've been running it on rooted Oreo (older version, not sure which specific, I know I had a made up LG logo to cover that strange "security breach" warning that usually appears after rooting) for the last 8 months or so and it worked flawlessly.
Today I started playing some game and noticed that phone had 6% battery left I plugged it in. After 15 mins or so, my game froze and screen started fading in whitish color. At this point it also became nearly unresponsive to on screen and power buttons. I ended up pulling the battery and once reinserted the phone vibrated as usual on start, however there were only black backlit screen instead of usual LG logo. Further down the road I heard AT&T ringtone, meaning the phone has booted, but the screen remained black. Eventually the phone rebooted and repeated all this a couple of times, after what it stopped going further of couple of backlight blinks. It also would get quite hot while charging.
I tried using an older charger (from a Samsung phone, that does not provide the fast charging), and it appears not to get hot while charging and after some time I could get a vibration after pressing the power button, but still black screen and it wouldn't load any further. Also I measured battery voltage before putting it on the older charger and it was around 2.7 volts. After about hour on that charger it came up to 3.4 volts. After attempted power on with charger plugged in it got hot again and reduced the voltage to 2.9.
If somebody had a similar issue, please share how did you tackle it. Thank you.
Well, answering my own question just in case it would help someone else. A gentlemen at my local repair shop told me that it was a screen issue and quoted me $140 for a repair...
I have a G900V and it's rooted running Magisk. Previous to last month, I was having no issues with my phone. I've been having issues with black screen of death (captive buttons work, phone sounds, vibrates) but screen wont turn on. It then vibrates twice and I have to battery pull to turn it on. Leaving battery out doesnt help nor does keeping power button pushed in and released for any amount of time. It has rebooted once, and a few times now screen glitches or freezes. I've tried 4 different roms now Lineage 14.1 / 18.1. I did recently update TWRP to the newest version and Magisk 21.4 from 20.3. Otherwise I have kept the same apps and everything else the same.I've also installed brand new batteries, thinking that could have been the cause. My phone charges fine. Any ideas?
