Horrific Screen Touch Automation Problem - G4 Q&A, Help & Troubleshooting

Today my new LG G4 started behaving abnormally all o a sudden. It started showing self generated automatic touch responses. I have seen this symptom once before in my previous G4 which I eventually replaced. I had to pull off the battery twice to make it normal again. But it almost gave me a heart attack.. It is such a new device but what is this???

LG optimus 7 problems

Hi guys,
This is what has been happening to me. Last night while charging my phone, I noticed my phone was extremely hot and noticed the phone did an automatic reboot and it got stuck on the LG symbol, so I took out the battery, and put it back in after it cooled down. I turned it on and it seemed fine and since it had full battery I left it on my desk without charging.
Today I was watching a video on lazy worm youtube app and it did a restart and I got an error message that stated something about my sim card or memory card malfunctioned (sorry can’t remember) and gave me an option to turn off or another option which I can’t remember. Then after restarting it worked fine and went back into the app and in the middle of the video the same random reboot happened but this time it didn’t give any error.
Just right now as I was syncing my phone on my pc everything was fine and i left it tethered to my pc after syncing and continued with my work then ANOTHER random reboot. So I’m wondering if anyone else is experiencing this. Is there any solutions, or what should I do? Thanks.
Your mainboard is dying. This is a relatively well documented issue on the LG Optimus 7 forum (scroll down a bit, eh?)...and the most likely fix is to send it in for service.
ah thanks! will check it out

screen not responding to touch inputs? (not sleep of death)

anyone had problem with the screen not responding after waking up?
There's no way to turn off the phone / make it respond unless to unplug the battery and plug it in again. Had this problem on the first GN and my second replacement GN.
Yep, happened to me the other day as well. There was a crash right before which made the phone reboot. Once it came back, the hardware buttons responded fine but the touchscreen was dead until a battery pull.
Hasn't happened since though.
Had this at lunch today also had it a few days ago.
When returning from sleep the touch input seems to be completely unresponsive.
I left mine for a while to see if it recovered, it did, it came up with the crash report for "System Process" The screen was then responding fine.
Weird. This is indeed different to the sleep of death, because the screen comes on.
Although maybe it's related in some way?
This just happened to me, and so I googled to find an answer. It thankfully led me here. It's like you guys described: I just tried unlocking my phone, but the screen was completely unresponsive. Not a single touch would register, even when trying to touch the Power Off option.
I read robaldred's comment, so I decided to try the waiting game. Thankfully, after a few minutes the screen just came on and the device was ready to use. I don't believe I saw a crash report though.
I hope this won't become a serious issue. I'd hate to be stranded at a point when I need to use my phone.
I had this problem too. have you guys used custom notification sounds?
Sent from my Galaxy Nexus using XDA App
I had this exact problem and I found it was due to Juice Defender (I have the Ultimate version as well). It kept happening after I installed and but since removing it over a week ago no problems.
Just had it happen here, had to pull batt. Using BatteryXL but will keep it on and see if it happens again.

[Q] lg g3 touch screen troubleshooting

Hi guys question for you. Ok I have an lg g3 about 2 months ago I dropped it and the screen shattered so I got a new LCD and digitizer. I installed it and it was working fine until about a week ago. The center stopped responding to touches unless I pushed a little harder and now yesterday the phone became almost unusable. I can hardly open the lock screen and to to open an app is almost impossible. Anything I can do to resolve this problem. I have rebooted and cleared cache and also done a factory reset. I have also unplugged the LCD and digitizer and plugged them back in still nothing.
I know this doesn't help but I am having the exact same issue.
For me I had my screen replaced and notice deadspots from time to time that would go away if I locked/unlocked the screen. So I did a little research and everyone was saying how I should do the touch firmware upgrade in the hidden menu so i did, and that killed the touch completely. Same issue as you, I can barely enter through lock screen. I even tried restoring to stock through .tot that didn't help.

D850 Screen unresponsive randomly HELP!....please?

Hello everyone, I just recently got a G3 and it was working fine for the 1st 2 days, no issues. I was sending a text to a friend earlier today and after it sent, it completely froze. After doing a soft reset it took forever to boot up. Once it booted up, it seemed to be fine. about an hour of operation, the screen looked as if it was freezing because it wasn't recognizing any of my touches. i decide to flip the phone sideways to see if it was actually frozen but it changed to landscape just fine. Sometimes it comes back to life then goes off again shortly after, and other times, i have to soft reset. I've tried the following to no avail.
Took the phone apart and cleaned both connectors.
Re-flashing the rom.
Trying 4 other roms.
Returned to lollipop stock.
I can't figure this out for the life to me and worked my ass of to be able to buy this phone. Any help would be appreciated as I can't afford to spend any more money on it!
I also have this issue, it's been ongoing for a few weeks. There will be short periods where it can work just fine, then it just freezes up and does not register any inputs. The content on the screen continues to run as if nothing happened (videos and games keep playing). Turning the screen off, waiting a couple minutes, then turning it on can sometimes give me another minute of use until it freezes up again. Also of note, when the screen is unresponsive and I press the power, it will dim to very low levels for a few seconds before going fully black. When the screen is being responsive and I press the power, it goes straight to black, as is normal and expected. From my testing, I've concluded:
1. This issue is not app dependent. It can occur at any time, and is not caused by alarms or overlays, such as blue light filters.
2. The issue is not from the specific battery I use. I've switched out between multiple batteries and used different chargers, none seem to affect the frequency of freezes.
3. Temperature may have something to do with this. When waking the phone after it's been sitting out in the cold, there seems to be a higher likelihood that it will be unresponsive. This is not always the case, which makes concluding that the issue is hardware related difficult, but some correlation seems to exist.
4. This issue started occurring shortly before I began having the popular "SIM Card Removed" issue, which I've yet to resolve (though can sometimes get the SIM card to work)
I am running stock 6.0 D85030p AT&T. I will post here again if I figure something out, but I have been trying for weeks without much success.

Lg G3 brickeD?

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.

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.
