Hi, from last six months my Lg G4 h815 started showing random black screen. Meanwhile the screen is black the phone keeps running (music, leds, messages). Sometimes I lock the phone, then I unlock and display turns on, sometimes not. I face this problem only in stock MM fw, not AOSP or LL. What can I do? Thanks
I have exactly the same issue... I returned it to LG (it is still on warranty time), but with a random issue, I think I'll have a random fix lol.
Did you found any solution ?

Is anybody have the same problem? Screen on my 5X sometimes goes black, its still working but its completly black. It is happening when Im using apps like snapchat, facebook, or sometimes i don't even need to do anything, it just go randomly black and after couple pushes of power button or even several restarts of phone screen back to normal. I tried factory reset but it doesn't work.
You should return it for warranty replacement (if you have not installed any custom ROM or modification...)
It happened to my wife's 5x, the replacement phone is just fine

Are you rooted? This happened to me yesterday twice. I'm on MDB08L, rooted with classic method and xposed installed with gravitybox....
Also, I was low on battery, around 15%
I've had it happen a couple of times too. Seems totally random, doesn't appear to be linked to any particular app, process, or battery state in my case.
I have installed Chroma rom this morning. No black screen since then... I'll update tomorrow.
UPDATE: Second day with chroma, no black screen so far.
Update 2: still no black screen...
I'm experiencing two kinds of crashes with my LG G4 H815 (EU) with V20d firmware (was happening with V20a too). Bootloader not unlocked, phone not rooted, full stock.
-Freeze only: I can go for days with the phone behaving normally, then all of a sudden it decides to chain-crash wildly. When it crashes the screen freezes and the only kind of response I get is the screen dimming after the two minutes screen timeout (it just dims, does not turn off). After pulling out the battery to reboot it, it boots normally to home screen and then crashes again after some time (varying between 30 seconds to 2 minutes after hitting home screen). Rinse and repeat until it decides to stop (could not figure out what causes it to stop).
-Freeze and automatic reboot: this rarely happens during the chain-crash madness; the screen freezes but this time there are graphic artifacts on the screen. Then after about 10 seconds the phone automatically reboots (only to probably crash again with 1st type of crash).
Should I try a factory reset before sending it to assistance? Is this kind of behavior known?
If it's s/n 505 most likely it's hardware. Problem appeared only after update to mm? do you get overheating warnings?
Yes it is S/N 505. I didn't use Lollipop that much and this problem didn't arise the moment i updated to MM (almost a month after) so I'm not sure. Didn't get any warning, is there any way to actively check for overheating issues?
Definitely an hardware problem: re-flashed V20d kdz (data wipe). Phone froze again during initial setup.
If there's warranty, use it
About 3 weeks ago my D855 running stock 6.0 30b flashed with lgup (phone had worked perfectly for 8 weeks with no issues) started to shut down randomly. Upon rebooting the phone would not pick up a cell signal at all, rebooting the phone would just cause some sort of shutdown loop where the notification light would pulse blue green and the backlight would remain on but the phone would not shut down. only a battery pull would get the phone back on.
I sent it back to lg and they just sent me a new battery, this made no difference.
I have installed stock lollipop via lgup and then updated to v20n with lg software update tool and it has stopped the shutdown and loss of cell signal issue but its still experiencing random reboots. Not as frequent but usually once a day. Not app specific either.
The phone was repaired because of the crack at microphone area issue, about a month before the problem started occuring.
Im on 3 network.
Its booked to go back to lg on monday, anyone else had this problem ?
Hi guys,so i have a problem with my Lg g3 d855,for some time everything works fine and than randomly when i try to call my call window freezes,and it stays frozen.Then when i try to restart the phone it goes into reset screen and than just stays on black screen with green/blue LED flashing.I try pulling battery and puting it back in,phone boots,but i have no service,and my IMEI is Null,and baseband is unknown.I have tried many things,none of them seem to fix my problem,replaced the battery just in case cas i also get random restarts from time to time,didnt fix anything.Tried flashing custom Rom,flashing Modem,etc..nothing fixes the damn thing.
PS: I menage to get it to work after reseting few times with battery pull/insert,but than it randomly happens again.
If anyone has any suggestions they are welcome,also its out of warranty so taking it to repair is not possible,and im out of cash,so i kinda wanna see if i can work something out and use that as last option.thanks!
Hi there, first of all I've seen some other threads which kind of have the same problem but not quite. So here is my problem my touch screen isn't responding most of the time, it started happening like a week ago when it froze while trying to send a picture in messenger, after 1-2 reboots it started working again but after that the same thing happened while I was typing in messenger, so I thought it might be software problem and made hard reset and installed new stock android(that didn't help). The last couple of days most of the time it's not working and I'm using it with a mouse, but there are periods when it works for some time. I've entered the hidden menu(without updating the touch firmware because I saw that it might kill it for good) to try and test it and had 2 different results
- The touch screen firmware version on my phone is -1
- And the one from the photos that I've attached(obviously during this one it actually worked for a couple of minutes)
Something else I've noticed while the touch isn't working when I turn off the screen from the power button first it dims the light for 2 seconds before really turning off.
Other things that I've tried are changing kernel, opening the back of the phone and reconnecting the screen to the motherboard(which helped the first time and it worked for 1 day or so but doesn't help since then) .
There is one more strange thing for some time now may be 3-4 months the phone has problems connecting to WiFi)
And one last thing after the screen problem the phone started booting quite slow some times and showing "Process System Not Responding'"
The phone is running on Stock V30b MM and hasn't been dropped for a long time
The problem is that I don't know is it software problem, screen problem or motherboard so any Ideas will be appreciated.
