H815P with Crazy display or Phantom touches.
Buy an old LG G4 H815P with a broken screen and put its motherboard in my H815 TW case.
In principle it worked well, but when the hours of operation passed I noticed the odd ghost touch. At the end of the day the ghost touches have already become a crazy screen and the phone cannot be used.
I got a second screen, this time an H818P screen, and the same thing happened, it worked a few hours well and then a crazy screen.
flash android 6.0 kdz V20P and unlock with UsU and put LINEAGE 16, android Pie 9.0 using V20p modem.
Now the screen is much more responsive and the phone instantly goes crazy. Impossible to use it like this.

What could be the problem?
failed motherboard?
Old faulty batteries?
Any solution to try?
I can not test new batteries because the COVID19 quarantine my country is blocked and battery prices rose to ridiculous values.

So my Gnex went black over a year ago, I tried all the guidance at the time with combinations of plugging and battery pulls. It just plain would not respond in any way to any stimuli. I got a new Nexus 5 and lived happily ever after until the discussion of Lollipop on Gnex resparked interest.
So, I gutted the Gnex, everything looks good, but that little tiny button cell battery on underside of mainboard screams guilty.
BUT the little bastard is SPOT WELDED in its holder 6 places. 3 on top, 3 on bottom. Really? Yeah.
I manage to carefully sheer the welds with a tiny flathead. It reads ML414H.should be 3VDC, It tested out at 2VDC. Enought to keep phone from booting? Charging?
Anyway, I'm over here in Norway, and lets say getting on of these tiny batteries would apparently requires some creative logistics. (They dont even have Radio Shack )
I need help tracking down one to see if its a legit fix.

This battery is simply a backup battery for the system clock. The problem is not with it.

I've read about there being touch issues. I've noticed it on my lg g4 too. It's not bad enough to not like the phone but I do notice it from time to time (try to open an app and it does not register the touch). I'm hope they will send out an update to fix the issue.
Facing an issue where am unable to pull down the notification bar when the mobile is placed over some soft surface. Even multi touch app does not detect any taps. Sometime when swiping the notif bar, it recognizes that as double tap and locks the screen. Anyone facing such an issue?
With the G2, it would develop a "bar" that wouldmt recognize touch. Open a drawing program and draw all over your screen to make sure there arent any bad spots. Sounds like your g4 maybe defective.
Hello everyone!
So the top 3/4" of my HTC 10 stopped working about 4 months into owning the phone. I tried getting HTC to replace/repair my device, but I forgot to reset it to stock before I sent it in and they decided my warranty was now void and the logic board replacement would run me $350+. I've been using the device for over a year now by using gestures as a workaround.

I had been researching ways to change the positioning of the screen down so I could use it more or less as normal.
I came across the overscan command in ADB. I shifted the screen down to 0,300,0,0 and to my surprise the screen did the exact same thing as it was before I added the margin, just lower down the LCD.
With this I figure the problem must be a software issue instead of a hardware issue as HTC originally implied.
I am currently running ResurrectionRemix 5.8.3 although I have tried several roms and they all produce the same problem.
Is there a way to adjust the digitizers margins so that my touch will line up correctly?
It may be worth noting that when I touch the "dead" area, it does register the touch just under where I'm actually pressing.
Any and all help will be very appreciated.
What is happening to my phone!? I dont even know how to search for this. The LCD still works fine. Touch works fine. Its almost like something is separating internally causing a contrast difference in this odd, blotchy pattern among the pixels. A white screen shows the issue the best. Less back light makes it harder to detect. It was just slightly noticeable in the upper corner 24 hours ago.... now its 20 times worse! I got this phone from Verizon the day it came out. It is unlocked using Sunshine and running Viper10 and has been since I got it unlocked. Cant imagine that has anything to do with this though...
Has anyone else ever seen this or know what it is or what causes it??? I am at a loss here.

Wow, not one response in almost 2 weeks... Has no one ever seen this before on any device!?
As strange as this was, whats even stranger is that the phone has healed itself! The screen is now 100% back to normal. I have no ideas what happened, but ill take it!
That's awkward
Have a look at this ...
scary :laugh:

My 835 did something similar the first "real" restart after Android 10 got installed, went on for ~20-25 seconds I would say, then I pressed the screen on/off button twice, all came back and I could unlock the SIM and continue ... hasn't happened since ... but was indeed scary
Marcher
I had the same problem too. Another reboot cleared it.
Didn't have this issue. But I noticed new battery settings and turned on the "protect battery" feature and now seemingly my sot has improved by a crazy amount I'm not sure if it's a bug.
The feature basically just makes it so your battery won't charge higher than 85%, and then when it says 100% after restart, it's the same as just 85% before. I can't post image for some reason, but I'm currently at 53 minutes of SoT and I'm still on 94%..

Got the same issue randomly (twice since Update), thought itˋs Hardware(GPU) Problem. Iˋm going to do a Clean Android10 Install if i have the time to.
