Note 8 phone screen glitch - General Questions and Answers

My screen has been glitching recently as if it's broken but it happens randomly and for varying periods of time. Also gets better when the brightness increases. Anyone seen this before and know an easy fix without replacing the phone?

[Q] Random touch Screen clicks when phone isn't operated!

I'm using Fallout v5 ROM from a month without any problem, but lately I have seen a really irritating touch screen glitch which I know is not ROM related.
Problem:
I'm seeing some random screen clicks and swipes (as though a ghost is operating my phone) and during this my phone touch screen becomes un-responsive. But I can turn the screen off using the power button and after turning the screen on sometimes the problem does reappear. I did some googling for this problem and found that many android users have seen this but none have a solution or know the root cause of the problem.
The guesses as to the Root of this problem floating around are:
1. Caused by erroneous charger (I charge from PC or from htc charger only)
2. Caused by high temperatures or humidity (I have seen this problem other wise too)
Lately the frequency of the problem is increasing and sometimes the phone is unusable. My theory for the behavior is that the battery needs replacement as my phone is already 1.5 years old. Willing to try any suggestions you guys suggest. I have already done a full wipe and tried 2 ROM but the problem re-appears.
Any help is appreciated.

[Q] Screen Issue? (XT926)

I received my XT926 as a refurb and I have been experiencing a strange screen issue.
I will often have my phone on a dock, charging and sometimes I will notice the screen is black like it's off, but the touchscreen is responsive. Hitting the power button does nothing but it makes the sound as if I had locked the phone. Hitting the power button a second time will turn the screen on like normal operation.
Very rarely I have noticed the screen will turn off while I'm actually using the phone and it's a weird effect. The easiest way to describe it is that it looks like entire lines disappearing randomly over a period of 1-2 seconds, going from all visible, then to all black, kind of like slatted blinds being closed, but at random. After this, it displays the same symptoms as if I had found the screen off while in a dock/charging.
Now, I don't want to say it's related, but I first started experiencing this on the Stock KitKat update from Verizon. I am currently using Cyanogenmod 12 nightlies and I am experiencing the same issue. It seems to be happening with greater frequency.
I have also experienced the blue screen effect when certain animations/elements/apps are up on my screen, but I think they are unrelated.
Also, there is a faint discoloration bar about 2/5ths of an inch thick uniformly vertically from top to bottom of my phone on the righthand side (just under where the notification bar would be if turned horizontal).
I've tried to find more information about this but my search results have been relatively lackluster (90% of the results are trying to sell me the phone or specification pages)
So I'm breaking down and turning to here. Does anyone know what's going on here? My current theory is that my screen is going bad. I have no intention of replacing the screen on this phone (would rather just buy a new one), so any suggestions that don't involve physical hardware repairs would be appreciated.
I thought i was the only one experiencing it.
The screen turning off with a weird effect happens rarely but yeah it happens. And the blue screen effect, i noticed it only happens when im on the youtube app when the video stops working because of my connectivity issues.
Im not rooted nor is my bootloader unlocked. On the latest system version. Sounds like a software problem but hey im no expert.

i also have this with my referb i made moto give me my money back and they let me keep the phone for me it was very rare but my new phone also had a really bad screen all yellowish and bad white balance in low light if you are unhappy with it call them and say you are unhappy with the replacement here is the white glove number 800-653-7185 they are more understanding and nice but you may lose you ability to unlock your bootloader on the new phone if it comes with the latest software just a warning
I have that screen off with lines slowly disappearing thing, too And, yeah, it's also a refurbished one, bought from one of the sellers on aliexpress... I thought Lollipop was the culprit or something like that. Oh, well... It rarely happens. And luckily I only have that, not the second issue you mentioned
I am having this exact same issue. The weird lines-to-black screen thing, and the flickering blue screen when watching video. Are you saying the solution is to call Motorola and ask for a new phone?
The blue flickering can be prevented by going into Developer Options and checking "Disable HW Overlays".
The discolored stripe on the screen sounds like burn-in; these AMOLED screens are much more susceptible to burn-in than the LCD screens used in older phones. Whomever owned the phone before it was returned to Motorola probably had something running on their screen continuously with a bright-colored bar at the top, likely in a car or desk dock. The screen is very easy to replace yourself with an eBay part, if you're inclined; it involves 2 screws and 2 connectors.
I've seen the lines-to-black thing exactly twice since I got this phone refurb two months ago. Sorry, I don't know what causes it or how to avoid it, but the workaround is quick and simple enough that I'm not worried about it, yet.

Nexus 5 Black Screen Issue

Hey, I m facing problem of nexus 5 black screen issue it turns on but nothing shows on display...(display tested works,and flex cable also replaced)
Can anyone help in this??
There is no display in fastboot mode either?
If you are sure the display connecting cables work, sounds like a motherboard problem.
I'm not trying to hijack the thread, but I thought it would be easier to post in here since I seem to be having a similar issue. I can't figure out if it is software-related or hardware-related.
I recently updated my Nexus 5 to Lineage OS 14.1 (11/7/17) and my screen began glitching. After an indeterminate length of time, my screen starts bugging out - the touchscreen won't register any touches, pixels get glitched and then it usually goes black. Sometimes the display will reset itself, and other times it will stay just black. Now the odd thing is if I force a reset by holding the power button down, I can get it to reboot and usually it fixes the issue... briefly. I've noticed sometimes however that even the boot animations will glitch out too, but by the time it gets to my home screen it's just fine, again for an indeterminate amount of time
The phone was bought used from Swappa probably almost a year ago now. Worked great up until now, I'm sure it's been dropped before both by me and the previous owner, but the screen itself from the outside doesn't show any signs of damage (No cracks, scratches).
I've since gone back to an early October build of LOS14.1 that wasn't giving me any issues like this, but I'm still getting them. So I'm leaning towards it being a very odd hardware issue or maybe I need to Factory Reset and dirty flashing updates is catching up to me.

Screen burn

Hi guys!
Anyone else experiencing screen burn? The image of the AOD is still slightly visible after unlocking, it lasts a few seconds, I've seen that when happen with other stuff too like YouTube when not on Fullscreen, the part below the video leaves a trace for a few seconds after I leave. I've had the phone for 11 months only so it's a bit disappointing. Now I'm wondering, has it always been there but I just started noticing lately?

My Huawei mate 30 pro 30 keeps flickering on bottom screen before switches off

Anyone encounter the issue with Huawei phone that flickers non-stop before switches off ? This happens when the phone has been in use for longer than 15 min. Quite annoying as it really pains the eyes. The phone was purchased only end of 2019 and I'm considering of replacing it because of this issue.
Make sure that your phone is fully charged. If the battery is low, this could cause flickering or other strange behavior. You should also try restarting your phone by holding down the power button for several seconds until it turns off. If neither of these solutions work, you may need to take more drastic steps such as resetting your device or seeking professional help from a technician.
In any case, remember to always back up your data before attempting any fixes in order to avoid losing important information. While dealing with technical difficulties can be frustrating at times, don't give up hope – there's always a solution out there!
replace it huawei phone is not worth the effort. most likely part of the diode in the screen died or something worse. when things shows up on screen most likely that is hardware issue
