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

Few days ago my phone began to shutdown either immediately or after a short freeze of the system. This happens in many situations, although mostly outside/when I'm on the move (I tried disabling GPS but it didn't help). Usually when I switch it on again it either shutdowns just as the lockscreen appears or doesn't work at all until I remove the battery for at least 10 seconds. The latter sometimes helps and the phone works properly for a couple of hours and the whole thing start over. I tried clearing cache, restoring factory defaults, changing the software completely (Fullmics, LineageOS) but nothing helps. I made sure that this is NOT battery related - I have a spare one and it's all the same.
I'm not sure whether the issue is hardware or software related. Here are my suspicions:
Why it might be a software issue:
- Just before the phone shut down for the first time I noticed that the upper part of the display stopped working - I simply could not pull down the notification bar. I rotated the screen and noticed that the same thing happens to the menu buttons which obviously replaced notification bar in the upper part of the screen. Eventually it turned out that this is not a defect of the screen and that part of the screen simply froze. After reboot it worked normally for a while and then froze again. After changing the software the problem seems to be gone.
- When I'm in recovery mode (TWRP) the phone usually is stable, it shut down only once or twice
Reasons for hardware:
- For a couple of months now the Wi-Fi is not working properly. It disconnects and whenever I try to reestablish the connection it goes into "Saved->Connecting->Saved". Maybe this is just the next step towards the graveyard?
- It's about 6 months since the warranty has expired
Have you experienced this and/or have any idea what's going on?
EDIT: With time it was more and more difficult to turn the phone on and keep it running and right now it's not turning on at all.
EDIT 2: I made it run again. TWRP works perfectly but once I reboot to System it shuts down almost immediately.
Nobody has any idea?
I'd guess it's the battery.
When I bought my G3 in Oct 2015, I had random reboots aswell, nothing helped (turning off mediascan, restore kdz via LGFlashtool 2014 etc.).
So I went ahead and bought another battery (7000mha) from ebay.
Never again suffered from those annoying random reboots
(Inserting the old battery, makes the reboots reappear, so that is postivie proof for the battery thesis).

As I wrote above, I have two batteries and the problems exists with both of them.
In that case try this:

Regarding your battery: You didn't only get "original" batteries ? I have a third party one... All original ones I had so far failed me...
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 ?
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.
Weird thing happened to my lg suddenly
1) Touchscreen totaly unresposnive
2) Pressing power button brings up the power options with a huge delay (about 5 seconds), cant choose any of the power options because touchscreen doesn't respond to touch.
3) Hard restarting the phone with battery out, reboot takes forever (around 7 minutes) end up on the login screen with error codes "service is disabled" and "process system isn't responding", cant choose to terminate the option because touchscreen still is not responsive.
4) Did a forced factory reset. The reset menu seemed fluid and the reset itself seemed fluid enough, but when i got the setup the phone screen (get started screen) i was hit again with the "process system isn't responding" error. Also the huge lag of the OS and power button delay came back. Touchscreen also didn't work
Tried to take out sim and sd card, same result.
Funny thing: screen flipping is totaly fluid and flips on the fly.
update: The touchscreen suddenly started responding, but after about 4 seconds it became unresponsive again. Seems to be a hardware related problem.
After some extensive search i finally found a forum where similar symptoms exist:Google: "screen_becomes_unresponsive_after_5_10_seconds_of"
Gonna open her up and try the foil trick when i have time.
I can't really say but my original G3, from 2014, started behaving similarly last August. Screen was fine but I believe the emmc was failing. I remember going through batteries while trying to get the phone to boot fully. It would get so far and then restart itself. Before it got that serious there were errors, unresponsiveness, and lag.
Did full wipes, reformats, flashed different ROMs, to no avail. With older ROMs (Lollipop f.i.) the phone would constantly power off during boot. Always had to pull and reinsert battery. With newer ROMs it was better in that I got reboots instead. After awhile the phone would shut off or reboot even in TWRP.
Eventually I administered last rites. It had a good run.
LG G3 D851, AOSP-CAF 6.0.1, NanoDroid, MultiROM, XDA Legacy
Yeah i guess so, i assume the problems mostly came because of the overheating issues over the years, just like gpu has, constant temp changes on demand. I wonder would a oven trick to the logic board do something useful?
I baked my old gtx 780 and it has been running like a champ for almost 5 months now (Y)
Anyway i noticed that if i put my G3 in the freezer for about 10mins, the phone is alot longer responsive then just mere 5 seconds. Maximum i got was about 3 minutes lol. Guess i gotta carry a mini freezer with me from now on...
Update: After doing a 10minute bake @ 185C to the motherboard, the phone has been working fine. Will let you know if this problem comes back. If not then the bake did the trick.
Hello, I have an a5y17lte with latest official LineageOS 18.1 build which yesterday started exhibiting an issue with the screen where when waking it up the screen stays black. I was able to fix it by force powering it off, but soon it happened a couple more times, one time the screen not turning on after the 1st force reboot and thus requiring multiple force power offs to start working again. Later on during that day there were no issues with the screen, but since this morning this happens constantly and regularly and it always takes more than one force reboot to fix it. I have tried reflashing the system image, which worked for a bit before it started doing the same thing once again. Does anyone have a clue what could possibly be causing this?
