Slight display flicker - screen bad, connector or motherboard? - T-Mobile LG G3

Purchased a "used" D851 on eBay - received it today. Physically the phone is perfect - no scratches or marks of any kind, zero bad or stuck pixels and the screen's background is white with zero yellowing. The only issue I can see is when the display is turned up it has a tendency to slightly flicker - like its adjusting brightness but the setting is not set. Does this sound like a cable problem, motherboard chipset or problem with the display itself? Understand that there have been issues where the screen fades to black but I have had this issue.

Check if display is ok

Hey,
I got my Galaxy Nexus and want to know, how I can check the most common issues with my screen? Which are the most common issues? Which issue say that my screen is defective? Which "issue" is rather normal.
(I see little lines in grayer background, is that normal?)
Defective would e stuck, dead pixels on full screen colors brighter darker dots, but with this DPI you would need to strain a little to see one and one issue that I have seen from a friend is the screen started to peel off (I guess the digitizer from the LCD)they replaced his phone
Normal would be the persistent image that AMOLED has go to the market for example wait a little then scroll to the right and you can see lines on the screen for 0-2 seconds
Hope this helps

[Q] New Note 3 has discolored corners at high brightness

I just received a new T-Mobile Galaxy Note 3 and I'm wondering if there's a problem with the screen. As you can see in the attached photos, when the brightness is high (about 50% or higher) and the background is white (or other light color), there is significant and noticeable discoloration in all 4 corners of the screen. The second photo also shows that there is an area that is slightly darker (grey color) that persists constantly.
I've read through the forums and don't see any specific mention of this issue with the Note 3, so I'm wondering if anyone has any idea if it's a bad screen, or do all Note 3's display this behavior with high brightness and light backgrounds? If anyone has any thoughts, please let me know. Thanks!

Do you also notice the discoloration when using it with Chrome or the Internet browser? If so, replace it.
is this a NEW one or a refurbished replacement/exchange? seems like the screen is bad. mine doesnt look like that at all. if its a replacement have them send you another one. could be previous water damage
do you have a screen protector on it? maybe its polarized film and causing that effect?
Yes, the discoloration is present in all apps. The seller told me the phone was brand new (not refurbished) and there is no screen protector. Thankfully, he has offered to take it back and give me a refund. Thanks @Limeybastard and @rlee008 for the help!

LCD ripple on sharp, medium pressure touches at bottom of screen

This video popped u on /r/android on Reddit.
Tested the same thing out on my device (using any completely black background), my device seems to be affected by this as well. Are there anyone else experiencing the same issue? Want confirmation before I decide to get my device exchanged. Mine has a Tianma panel.
EDIT: To test it out you can just download Backlight Bleed Test because it starts off with a black background to tap on
I have the same thing, this is just the way the screen is. That ripple is technically all smart phones and even tvs that have flexible screens. It's because the panels layer is very thin and connected to the LCD panel

Black Bleeding on Screen

So my screen is having issues when I scroll and I know this happens on this device. The question is do all the devices do this or is this just an issue with certain ones. Is my phone broke or will it be fixed with an update. The smearing is pretty bad and I notice it even with the brightness turned up.
Every OLED device I have has done it, but I haven't had an LCD device for a while. So I don't know if it's a characteristic of OLED screens or all screens. My last device was Samsung and had it pretty bad.
I'm having the same issue,
It bleeds/smears with dark/black color when used in dark i.e no light in the room.
I think it happens all the time, just that its visible and annoying when we use it in dark.
What did you do? Did you get it replaced?
Hi!
Same here... It seems normal, anyway with two years warranty if something is wrong with screen (black bleeding, burn in, ...) Google have to repair it or change the smartphone.
Regards!
It should only be visible in low brightness. It's normal for oled but the pixel 2 XL is a bit noticeable because Google set the gamma to high. So it can actually be improved through software.
If you see black smear etc during the day and any other time than maybe at night when the screen is at low brightness I would rma it
Seems like sensors are causing problem if move phone around in dark it will go away I have a case and tempered glass on phone

yellowish tint/tone on screen,known issue or?

Well,this frustrates me a lot,I'm just uploading video so you can see and compare to some cheap other chinese phone.
I'm noticing yellow tone all over screen,kinda like there is a night filter on with very low bright nightlight settings.
I increased brightness all the way to 100 % didn't help.
I also removed plastic cover from phone,nothing, still present.
I even switched to Vivid display settings before that and reduced RGB (R channel all the way,G to middle and Blue increased all the way) and set tone color to cooler slider all the way,no difference.
So,since I purchased using phone,is this some software bug/issue or I got faulty screen (maybe some kind of damage from sunburn),or this is just how this display work?
I'm uploading video and will post link soon...
So anyone else having same issue,and what to do,be sure I can not RMA the phone since I purchased it used.
I'm also anxious that the screen might die on me soon.
But this yellow tone frustrates me a lot,colors are not accurate at all because of it.
does it show in safe mode? what happens after reboot, goes away and come back later or...?

Hmm,why would I want to access safe mode,I don't have issues with phone except bad wifi and this issue.Mostly it's noticeable while watching vids (youube),look here if you can see the difference...but maybe it is suppose to be like that.
I set color mode all the way to cool tone and no difference to my eye.
I called a friend on a drink which has N10+ too,then we put 4k Nature video on each of the phones at same time and same screen lightning intensity.
No diference,between them...so now I'm confused totally.
Are my eyes cheating on me,is it possible that there is slight yellow tint (like light night light filter) or something is wrong with my eyes?
Is it possible that maybe screen adapts it self based on ambient light so I'm seeing yellowish tone...who knows,but I do trust my eyes,though picture was the same color accuracy on both phones...
I'm totally confused now...
I have currently 2 note 10+ phones. One which still has the original display while on the 2nd I installed a new display with frame. Comparing both these phones now, the older display - about 1.5 years old with light screen burn on the bottom is more yellow than the new one. The new one is very white compared to the old one. Maybe your display is showing its age?
damn...it was a damn mask/cover with yellow tint over it,not display...how was I stupid.
Some weird posts here, didn't you say you removed the film earlier ?
