Weird Screen Behaviour - G3 Q&A, Help & Troubleshooting

I've been a happy fulmics user for a while now and had my G3 for a year and a half.
For the past few weeks, I have been experiencing a weird bug: On swiftkey, while typing, sometimes the keyboard closes, like when you press the "back" key or tap outside of the keyboard. I thought it was just swiftkey, so i tried erasing all the app data and starting over: No luck. Then I realized something similar happens when playing ingress, a location based game: Sometimes the screen would flicker like if another app gets the focus for a split of a second, then the game goes on as usual. Sometimes, while on a menu, tapping on buttons would be very hard: It almost seems like ghost screen touches. Finally, today I was trying to take a picture and noticed the same was happening, like screen flickering and some all getting focus for a brief period of time. The flicker effect is almost like when the screen is going to go to sleep mode when you press the power button or the screen timeout is reached.
When I first found out, I had my rom installed from scratch and only some apps (none of them system) restored with TB. Then, I tried with different config combos while installing: Stock clock speed, overclock, stock sharpening, no sharpening..... but I still have the same problem.
Does anyone else have the same issue or am I the weird one?
No Xposed whatsoever.
Thanks

BUG: screen lock does not kick in

first i thought it was launcher pro's fault, but after changing launcher and rom release i'm pretty sure it's something else i haven't tracked down yet.
just after a reboot phone works as usual: screen lock runs after 30 seconds or by clicking the power button
after a while (days or even hours sometimes), the screen lock does not kick-in anymore: the screen just turns off and when you press the power button the phone is already unlocked.
i noticed that when the phone is in this "lock-bug" mode the notification led constantly shows a faint red light (you can barely notice it in the dark because it's really faint).
tested with:
launcher pro
go launcher
factory rom 2.21
blurless 2.34
I used to have the faint red light on after flashing a new rom.
It disapeared after I changed display setting to not automatic brightness.
It seems that the faint red light is the light sensor.
But I know nothing about your screen lock problem.
I have run into the same thing. I have not yet noticed the light, but I've had the screen lock stop working on my phone twice (I bought 3 phones 5 days ago for work). Like you, a simple reboot fixed the problem. I also tried toggling screen lock in the settings, and setting up a lock code, to see if the screen lock would start up. Both of my times, the first I noticed the issue was when I received a phone call and didn't have to swipe to answer, but that could have just been coincidence.
It isn't really a big deal for me or the employees, but it is a nuisance.
Happened to me as well, twice. First time it was just annoying that I had to reboot, second time it drained the s**t out of my battery in three hours.
So it's a bug allright.

Inverted Screen...Possible Fix...Works for me

When you push the power button and see that your screen is inverted, then.... with the screen still on, hold your phone tight and give it a hard flick of the wrist. This has worked twice for me.
Running Calkulin's 2.6, Overstew's ICS AIO, Launcher Pro
Is this working for anyone running different setups?
can anyone verify that I wasn't drunk when I wrote this? The wife says I didn' t do anything today but get ripped. I told her I helped a lot people...just not her.
I have had the screen invert once... I just rebooted...
I have also had my entire screen go magenta for some strange reason...
The screen "appears" to be inverted... but it isnt... at least not to the phone. unlock the screen with the same manner you always would even though the visual cues are wrong. What ever lockscreen you are on, just do the same motion again. then once in the normal home screen, rotate it around a few times and it corrects itself.
I know exactly what you are saying about being inverted but still fully functional....giving a shake a shake with the snap of the wrist solved the issue without playing games.
Download Spare Parts from the market and set "Window Animations" to "Fast." Haven't had the screen inversion problem since.
i had it one time and and using adw pro all i need to do is rotate my screen and it resets the orientation

[Q] Variety of strange screen issues occuring

Apologies if this has been addressed before, but I searched and couldn't find something exactly like this...
Randomly one of 3 screen issues seems to be occuring on a daily basis:
1) Auto-Rotate stops working. Cannot get screen to rotate without reset (Yes, I've made sure auto-rotate is on in settings)
2) Screen will not Auto-Off. Even if I change settings to 15 secs, screen will not turn itself off. I have to manually turn it off. And, if I receive a text or any kind of notification it will light up again and stay on indefinitely.
3) Screen will not turn back on when trying to wake up device. Hitting the home button and power button both have no effect. Although the LED is usually blinking, and it seems the phone is still on.
For all 3 of the above issues, manually pulling out the battery and reseting the phone that way seems to always work. But, this is an annoying process to have to go through on a daily basis.
Also, I've noticed that these 3 symptoms don't occur simultaneously. For example, yesterday it wouldn't auto-off, but rotation would still work.
Not running any custom ROMs either

[Q] screen flickering

Hi guys,
anyone had an issue where the screen flickers really badly? Mine has been working great then today it did a weird glitch where the button bar at the bottom went halfway up the screen, and the screen flickered really bad, like a tube light starting up. Ive reset it and now its flickering like a fluorescent tube light. everything still works, but im on the phone to three now organising to get it returned.
cheers
Ray
ok, so an update to this. after leaving the phone on all day the flickering screen stopped flickering, however now i have an issue where plugging my ear pollution headphones causes the phone to now show as a headset with microphone, and the voice assistant to appear. It is also now getting really hot on charging where it didnt before, so my returns envelope arrived today, and its off back to LG for a repair. Seems very strange how its happened after a month of relatively light use, where my 2 htc phones were working great after 2 years of use?
anyway, lets see what rubbish comes back from LG
Home screen Magnifies
I have a weird problem with LG G3 screen
When i double tap to lock the screen .....Home screen Magnifies and if i double tap on that again it goes back to normal
I dont understand why .....can anyone please suggest me if any option to be tweaked under settings
Thanks

Always on display "flickering" when activated (on tap)

Hey everyone!
As the title say i'm facing a issue with my always on display.
I'll try to make it as simple as possible:
When I set the always on display to be always active it works flawlessly.
When I set the always on display to activate on tap (and last for 10 seconds according to the settings) it appears for roughly 3 seconds and then disappears for 3-4 and reappears flickering for 2-3 times sometimes showing the desktop wallpaper between each flicker.
Did anyone experience the same issue?
What I did to try and fix it was:
- tested both on battery and while charging
- factory reseted and then restored backup (which was stupid, that lead me to the second point)
- start in safe mode (to check whether it was an app causing troubles) but no such luck, problem still occurs.
- uninstalled "nice lock" apps
- changed some settings under the always on display tab
- cleared cache of the always on app
What you should know:
- I'm running android 9, not rooted and have nova launcher as default home
- After I factory reseted the phone I wanted to stop always on display from updating to test whether it was a new version issue but I forgot and didn't make it in time so I'm currently running the latest version
Does anyone have any idea as of why it's behaving like this?
edit: just wanna be a little more clear, flickering is not meant like a lightbulb it's more something like it turns off and back on after a delay (I'm sorry english is not my native language I can't really explain it any better)

i also experience the same.
this phone has many strange bugs.
when i restart my A70, tap to show always on display works for me for 2-3 times.
after 2-3 times working correctly, the bug starts.
after i tap the screen, it shows AOD for 2 seconds. then turns the screen off and then at the end of the 10th second, screen just flashes itself for the last time and turns off completely.
i think it is related to the fingerprint scanner.
because after i registered my fingerprints and turned on unlocking the screen by the FP reader, this bug ends.
after i tap the screen it shows both the clock and fingerprint icon at the bottom of the screen.
after 2 seconds fingerprint icon disappears. and the clock is continued to be shown until the end of 10th second.
but there is a minor issue, when the fingerprint icon disappears, the AOD screen brightness changes. dims or brighter slightly.
can you please try tap to show AOD, by enabling the fingerprint unlocking?
samsung ?

Hey! Thanks for the answer, I can confirm we have the exact same issue. I also have the same brightness issue you described
Anyway, I have always used fingerprint unlock though so I don't know what to answer you.. I only recently noticed the weird behavior. I did a couple things to test and I found out that enabling the "fingerprint" icon showing in the always on display seems to "fix" the issue of the flicker but not the one of the brightness change (after enabling it i've yet to see the problem occur), you should try it and let me know if you see any improvement. It's probably on samsung's end though and hopefully we get it fixed with android 10 or earlier
I'll take this chance to ask you another question; two weeks ago I received a software update and ever since that day I noticed my battery to be lasting waaaay less than it used to, did you update your phone as well? Did you notice a battery drain?
I have the issue both of you talking about.
hello, I had this same issue and what I did was turn the phone off, and booting it up while pressing "Volume Up", after entering a black screen with many options, I selected wipe cache. It has worked without a flaw since then. There's lots of bugs with this phone. I recently had a problem where the USB port will detect a device and "plugged and unplugged" it, making my phone unable to dim. Thankfully I was helpful.
