Screen flickering

hi!
I recently bought a xperia and noticed that the screen is flickering when you turn off the automatic adjustment and turn the screen to maximum. Is this normal or should i return it? its very innoying. It's the light in the bottom of the screen that flickers.
I would return it. Mine does not do this, so I wouldnt consider this "normal"
seems that you have a defective retroillumination led... return it
yeah, definately not normal - mine doesn't have this issue
I also recently received my X1. I also note that the light of my screen flickers but only with certain software. It vibrates on the left when loading windows, and on the black bar in touchflo3d between the start menu and the clock ... I can't see if it is a hardware problem and therefore if I should get the guarantee

[Q] Sudden screen black out but phone is on

I am having a problem with my Galaxy SI-9000 screen. It suddenly goes black and have to pull the battery to get back the screen. However when the screen is black the phone is still working because if I give a call the phone rings but the screen is black and can't see any thing? This started happening from yesterday, since then it has happened twice what may be the problem?
I am testing an application I have written(for battery use) and it is accessing the GPS and the MIC every one min.. can this have any relation with the sudden screen black outs?

screen flickering

Hello guys, have any of you noticed this? Will try to post a video later. But the screen on my one plus 6t screen will change its color to somewhat like a screen on a night mode when you pull down you notification on the lock screen?
