Did you ever resolve this? My dad just gave me his tablet, and it has like a 2 inch wide column in the middle of the screen where a bunch of flickering black lines jump around. It only happens on white backgrounds, and the more white there is, the worse it is. In the settings screen, it's bad, but on the blue background home screen, they aren't there at all.
It's not a solid black bar like yours, but a bunch of thin, horizontal lines about 2 inches wide down the middle of the screen, almost on the mirror side of where your bar was showing up

Screen starts to glow on it's own???

Hi,
I don't know what's going on with the screen of my one-v...
well I press lock button, so screen goes dark, but after a while it lights up for few seconds showing me lock screen... then it goes dark, and after few second it does it again.
after 2 times it stops, but it is annoying when you put phone on the desk, that it glows so you start to think about coming call or text.
what's going on?
lolsss..
haunted maybe

haha well hopefully not
I thought at beginning that it could be caused because of apz running in background but I have double checked - there are not any

have you tried factory resetting?
Are you using an app like Keep Screen?
My friend had a similar problem when she used the Keep Screen app.
Have you received an update?
Try using another locker like GO Locker or Magic Locker. Inform if it happens again.
strange thing, but it magically stopped happening
That may due to your brightness settings which is set to "Automatic" by default.
well it was too early for me to say that problem is gone... it happens again today ;/
I have fixed level of brightness, no apps except battery life working in background... all newest updates installed.
any ideas?

[Q] Horizontal lines: hardware defect?

All of a sudden my screen looks like an old interlaced CRT. Fine print looks jagged and I can see an irregular pattern of horizontal fine lines, especially on a white background. Those lines do not turn with screen rotation.
I rebooted several times with no effect. The lines appear on the recovery screen, as well.
I should mention that my phone dropped on a tiled kitchen floor this morning, but the lines only appeared at noon. Everything else works fine.
Has anybody had this problem and managed to get rid of it?
Got it repaired under warranty.

Note 2 sometimes has a yellow tint

When i look at my phone on a white screen , sometimes it appears to be quite yellow while at other times it doesn't. Can anyone explain this and could it be caused by the lighting in the area I am using it? Thanks.

[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

LG G3 screen slowly turning white when screen is turned on

Hello, so I am experiencing a huge pain in my butt with my LG G3, the issue is that whenever I press the power on button to turn the screen on my screensaver pops up and looks completely fine, after about 5 seconds a white shadow starts to appear in the background and slowly starts to make certain parts of my screen invisible, but as soon as a lock my phone and turn the screen on its gone but the process starts again. May be a possible led problem or something else? I would appreciate any help I can get before I go and take the phone back to Verizon and see what they say.
What screen saver are u using? Have you tried hard reseting the phone?

Just a normal picture from my gallery nothing extravagant or anything, it's strange there are like dark streaks going down my screen, I cannot capture it on a screenshot so I'd have to post a picture of it.

Hello,
I have exactly the same problem. I am able to use the phone in all his features, but the display presents stripes of shadow white. These shadows disappears when phone gets locked and appears when unlocking after few seconds. How did you solve? Will the guarantee cover this problem?
