I recently got Xperia SP (less than day old) and upgraded it to Jelly Bean 4.3. However due to issues such lag and such I decided to install customs rom. I chose MIUI. Unfortunately due to my newer status I am not directly able to report this issue in the orginial SP MIUI dev thread
I encountered a problem with screen on MIUI build 4.3.7 installed from imanesaurus . I have attached a video file which shows the screen flickering issue. It is not really a whole screen-wide flicker, it's just localized flicker with varying magnitude of flicker. It seems this only happens on grey color as white and black seem to be fine. I do not know if this is a bug or hardware issue. From experience, I know cheap TN panel do this primarily on screen when it's producing grey color.
Has anybody encountered this issue? Is this a hardware issue or bug? I will also try different rom (FXP) and also see if going back to stock rom makes any difference.
Model Number: C5303
Android Version:4.2.2. JDQ39E
MIUI Version: 4.3.7
Thanks in advance guys.

hey buddy this bug is widely known it seems to be a hardware problem but it is not as it is not present in 4.1.2 hope sony will fix it in the new version that has been certified ! :fingercrossed: so if sony will fix then developers will fix it to
Are you using auto brightness? If so then this is the cause. On stock Sony 4.3 and even in 4.1 I have this problem. Sony has to create a fix for this

I just bought my Note used and found out theres a big problem with screen black and grays.
I've done some search and found that black clipping issue : http://forum.xda-developers.com/showthread.php?t=1559800
But I think my problem is not that or its much worse. I'll attach a photo of my Note with that same gamma test pic as in the above topic.
When I bought the phone it had stock ICS installed. I installed first GB and then paranoidandroid JB That's when I noticed the probem. (Not earlier, because JB backgrounds show the problem better.)
I tried everything in settings but nothing helped. The oddest thing was when I one time opened the lockscreen, suddenly the screen was normal. I was happy with that but later the screen went bad again and nothing seems to help. I've tried different kernels and different roms (stock ics&gb, custom ics and jb).
It is so bad that no way i can watch photos or videos with my Note
Is there anything I can do?
just unroot back to stock n then take it to the Samsung ppl
hi my friends
look at this :
http://www.xperiablog.net/2014/04/15/some-xperia-sp-owners-report-of-flickering-screens-after-update-to-android-4-3/
we need help :crying: can anyone help me to fix this bug ?
The 4.3 update has two big problems:
1: Screenflickering (according to parasense and some others it is a kernel issue?)
2: RAM
Both problems are in some way software related. However I never encounterd the Screen issue ( :angel: ) so thank God for that. I believe this is more of a hardware issue but I am not sure......
The RAM issue is a bigger issue and Doomlord is trying to fix it (see his DoomKernel thread) We are forced to wait until Sony pushes an update.. Which will be here soon see this thread: http://forum.xda-developers.com/showthread.php?t=2516663

we can only hope the sony said on its website "Under Investigation

I encountered display problems on my LG P880 when I updated to 4.1.2. I'm talking about these stripes on the screen like on this photo http://dl-1.va.us.xda-developers.co....jpg?key=uMRwlyKpJI8r3P5w_Li2bQ&ts=1412951971.
The issue goes away when I downgraded to 4.0, but I need a newer version on the phone, so I decided to try a custom ROM. I installed the official CyanogenMod 11 M10 snapshot, and I keep getting this problem, thought not as severe (I am getting the black stripes across the screen but not the "noise" elsewhere on the screen).
Is there a known solution to the problem rather than downgrading to 4.0?
Having tried a few LP roms (loved them all) missed some of the Sony stuff mainly the camera I reverted back to 4.4.4 and I'm still having screen issues? Which makes me wonder if the problem lies outside the ROM and is hidden the boot.img? and because its newer when you flash an older ROM it doesn't update this, I'm no dev and was wondering if this could be the cause of the problem, like back when unlocking boot lost the camera. But this time its a screen bug. Has anyone else who have reverted back to KK from LP still got this problem?
Update, I think the problem lies in the .157 update as I updated to this before LP. I'm also wondering if phones affected by the yellow tinge are affected more by touch screen problems? As I have a yellowish screen. Any feed back would be greatly appreciated
Hello everyone
I new in the forum and I wish know if someone else has had the next problem. Recently I replace the display and touchscreem from my xperia z1 and everything is perfect until after a while running a horizontal flicker begins to appear in the areas where there are lots of color or contrast between letters and background color , when I stand in a dark screen the words are more clear but flickering too.
Rule out that it may be the display because already tested with other display and the problem continues . Besides as I read on different topics all seems to indicate a problem with the operating system or overheating and video.
I tried several versions of KitKat and lollipop both for the device is C6902 , and all the fault persists, a similar experience and has had success in solving ?? I tried the thermanager solution http://forum.xda-developers.com/xperia-z1/general/flickering-brightness-charging-t3128804 but I do not know if I was right or I need something to work properly ...
I link the problem in video. https://www.youtube.com/watch?v=GghgVRy91aY
This is the same problem in other video with a better resolution https://www.youtube.com/watch?v=lOklu9z-vg0
Thank you for your help ...
