screen flickering when on white background

is this just something that shows on white screen as it seems ok on a dark screen
Screen shouldn't flicker no matter what. Maybe some settings in Oxygen? Or a faulty screen? See what HTC has to say about it.

[Q] Flickering when showing gray images

Greetings.
The screen of my Desire Z seems to be acting weird when displaying certain shades of gray and transitions from black to gray. Gray that is near black becomes much lighter than the rest of the image, although the color should stay the same.
I did a test with an LCD test image to see if I could find out what was wrong, and I discovered that displaying the image in vertical position gave quite a lot of flickering in the middle. Could someone download the picture on their phone and see if they get the same result as me? I get flickering when displaying it in vertical mode all zoomed out, but when I turn it horizontaly everything is fine.
Bump. Also, 10 characters.

Screen flicker test

Hello. Since getting my new HTC M8 the other day I noticed that the screen can flicker for a fraction of a second when in the setting menu.
The issue really comes to light when you use a screen filter, I use the app that is literally called screen filter. If you set the app to about 20% and then you go into the settings menu you start seeing microsecond white flashes when backing out of and entering new menus.
Does anyone else experience screen flicker on there M8. I like to know if its my phone thats the problem or the screen filter app. If someone wouldnt mind testing my steps above out, it also helps if you have the screen filter on in a dark room as the flashes become even more pronounced.
Thanks

Video lockscreen is black sometimes. Why, and how to do I fix it?

I'm not talking about the AOD. When I press the power button (or double tap the screen), it gets brighter as expected but the background doesn't show up. It just stays black, but the screen is brighter.
Why is this, and how do I fix it?
Only happens with video wallpapers on the lockscreen. Sometimes it's black, sometimes it shows the video. I feel like this only started in the last day or two, and it worked fine for the past week since I got the phone.
Anyone?

Question Screen issue or software bug?

Hi!
I have received my Red Magic 8 Pro and immediately noticed something. The selfie camera is visible if the background behind it is simple. For example just a simple white or gray background. Depending on movie sometimes it also becomes visible under cartoons like Rick and Morty, however during normal movie I cant see it.
Is this normal for this phone?
Also, the software which handles the pixels in front of the camera sometimes can become bugged and a visible line is displayed. I can reproduce this issue by pulling down the notification bar and holding it at 1 spot.
Does everyone experience these issues ?
That's normal, especially if the screen is on 120Hz, and at low brightness. It's the so-called green tint issue.
