screen pixelating - G4 Q&A, Help & Troubleshooting

I've had my Tmobile G4 for almost 2 weeks now and the screen pixelates every single day. The weird thing is it only happens on the bottom left corner of the screen and the size of the pixelation varies. It happens more often when I'm watching videos or playing games. I'd take a screenshot but it's almost impossible to capture because it happens randomly and so fast that I'd have to hold the power and volume down button before it happens in order to capture it.
Is anyone else experiencing these issues? I prefer trying to fix it than bringing it to the Tmobile store where I'd stand for 10-20 minutes waiting for it to happen so they'll believe me.

Power button issues

For the past couple days I've been having issues with my power button. It seems that, for about half the day, the power button will not work at all. I can't bring the screen back up or shut the screen off. Also every now and then the power menu that comes up when you hold the button down would just come up by itself. The other half of the day it seems to work just fine. For now I've just set it up so the screen never turns off, but obviously that drains power and will make me butt-dial everybody. I took it into a Sprint store but of course it started working like 10 mins before I got there so all I got was a "failed to reproduce problem" thing. After much haggling on the phone with them today I convinced them to send me a replacement, although it's backordered. Has anyone else had an issue like this with theirs? I searched around and couldn't find much. Does anyone know a way I can lock the screen without turning it off? That would come in handy while I wait for the replacement.

[Q] Anybody else's screen shut off randomly from time to time?

My screen will sometimes shut off after only a few seconds, long before the set timeout, and it doesn't seem to be tied to any specific activity. I could be browsing the web, on the xda app, sometimes at a menu screen of a game, it doesn't seem to matter. When this happens, the power button brings me right back to what I was doing, not going to the lock screen. I'd say it happens 5-10 times a day. It's not that big a deal to me, more of an annoyance than anything. Anybody else experiencing this?

Bummer! I've been fortunate with my device/roms, haven't had any problems except one week my notification light would shut off while charging for long periods of time. On calks 2.8.1

I figured out what was causing it- power saving mode. I turned that off, the problem went away.

LG G4 screen turning itself on after timeout

This issue started about 3 or 4 days ago for the record. I have been trying to find a solution online but I have yet to come across a real solution (other than sending it in to LG for 9 days (completely unacceptable)). It happens whenever I turn the screen off, either through the lock button or the double tap. The screen will power off correctly and then turn itself back on within the next second. If i leave the screen to timeout at 15 sec like I have it set to, the phone will dim and then the screen will close, only for the screen to immediately turn itself right back on. This is killing my battery life and making my phone constantly overheat.
If someone has found a solution please share it with me, I am reaching my wits end

Screen turning off when watching videos

I have had this phone for a week now and am finding that when I am watching videos in landscape mode that the screen will just suddenly turn black, the only way to get it back is to press the power button but then you notice that the video has continued to play so you have to keep rewinding a bit to see the bit you've missed.
Does anyone else have this problem, and if so is there a fix for this?
It is really annoying as you can imagine!

Display doesn't work. Changing screen to a new one do nothing

Hi everyone!
I have a problem with my watch for a while. A month ago my screen starded to flicker with yellow stripes and after couple of seconds it showed nothing. When I’m pressing the button I hear and feel wibrations from the watch, also Google Assistant hear me and speak to me. I thought that the display is damaged so I’ve ordered new one. New display arrived yesterday. I’ve put my watch guts to new frame with display and voila. I’ve press the button, watch is turning on and after about 1 or 2 minutes of joye yellow stripes appeard, screen started to flicker and then it stop showing anything. After that I rotated my watch in difrent directions and for couple of seconds screen starded to flicker and that’s it, dead again. Have you got any idea what’s going on here? What causes this?
Edit:
Strange thing. Last night (I don’t know why) I’ve press the button, and the watch launched perfectly. 5 minutes later screen started to blink and 15 minutes later screen goes off. I try to launch the watch today, I’ve heard and feel vibrations but screen show nothing
Regards
Peter
