You have a defective screen, this problem will get worse by time and the only way to fix it is by getting a new screen.

Lock screen flickering, is this normal??

Greetings XDA'ers, i have a Galaxy S II (international) and it's running stock ICS (XXWLPG) and the "problem" is that right before the lock screen comes up there is some screen flickering, black and white lines flickers vertically across the screen in about half a second before the lockscreen comes up. Its very hard to see this. But its easy to see it in dark rooms, like cinemas and such.
I have already returned the phone to where i bought it, the first time they changed the front LCD panel. and 2. time they didn't fix anything. And here in Norway the third time can get my money back for the phone if the same problem exists for 3 times. And if i do that then i can get the money back. And buy a S III ))
But anyway is this normal, they said they discovered the problem when i send it in the first time. and its still happening. so is this happening to you guys??
-Thanks for your helpfulness
Anyone???
I've not seen it, and you may need to wait longer than 2 hours to get a response from someone who has. This is a forum, not your personal instant messaging support client.
no it's not normal, pretty obvious

[Q] touchscreen calibration(?) issues on new screen

Hey guys,
I recently replaced my lcd ips screen on my Canvas HD after it developed some nasty cracks. As the cost of replacing the screen in an authorized service center in bangalore is quoted at around 6k, i thought of getting it replaced elsewhere. The guy claimed to have used an original screen, by the way. It came to 1.5k or so. However, I am now facing an issue with the screen at least once a day. The screen doesn't seem to be as accurately responsive to my touch as before, making things like messaging extremely annoying. Also, the screen goes crazy. At times, the notif bar with slide up and down involuntarily. Or, an application will close on its own even without pressing the home button.
I suspect it is a calibration issue. I tried looking up some applications to calibrate the touchscreen as the ROM I am using does not seem to have one. Also, I tried reinstalling the ROM. But, no change. Please help me.
ROM: CM11 (11-20141004)
Kernel: KashKernel (3.4.5)
Happy new year.
Thanks,
Suraj
damn
U should have go with 6k btw change the rom

[Q] Screen unresponsive

I just got my Xperia Z4 Tablet. I realized that the screen is not as responsive as the Z2 Tablet or even Tablet Z. And the thing that really bug me is that it is not always so >>> it is kind of "random" = end up may be 1 in 4~5 times I have to go back to repress - sometime even repress twice!
Do any one have the same problem?
I experience the same problem with myz4 Tablet. I don't have the comparison to a Z2 or Z-Tablet. But from time to time touching the tablet is not recognized. This is not limited to edges of he screen but also happened to me for buttons in the middle of the screen.

That's right! You know exactly what I am experiencing! Initially I thought is may have to do with the launcher - I am using Apex >>> so I try to revert back to sony's original one. But the problem is the same. Then I reboot the tablet and it seems to solve the problem for now. At least it seems to be a software issue not hardware - what a relief...
Let me know if you try any other method.

[HELP] Screen leftovers from other apps, (lcd image burn)?

So recently my phone has ghost images, leftovers from other apps on the screen. (eg. The top bar showing up ghostly when it shouldn't, controls of a game showing up on home screen after closing the game in a ghostly effect) It is not a software problem. I know it goes away on its own after some time, but it's very annoying and its freaking me out. Anyone else got this problem? How do I fix/prevent it
i got it to.not know hot to fix it
Very disappointed from xperia screen
I have also the same problem and it looks like a hardware issue. It's very noticeable when you increase the screen brightness. Notification bar icons/time appear all time against any dark background. Very annoying, even cheap phones don't have that problem.
Example I found online -> lnv.i.lithium.com/t5/image/serverpage/image-id/79782iF19656F933D1C741

I read that certain types of screen cause it, and it cannot be fixed except wait, which sucks, but I can't say for sure
Screenshots showing problem
I took these photos from my phone to show you how the screen retention problem looks like in Sony Xperia X.

Yes, thats exactly my problem. I noticed that it gets worse if the device is overheating
Sorry for the bump, but is any else having the same issue?
Mine seems to be getting worse and worse over time, to a point that it can literally retain half way up the display.
I use to have the same issue with my iPad Mini Retina until I took it in for a replacement and it hasn't happened since (2 years ago).
Any experiences with Sony replacing the display under warranty?
Thanks,

Not really. After buying the phone, I used it for two months without having this problem, then rooted, so no warranty

Wow, yours got on the next level. Mine isnt so bad. Actually , I rarely have the problem lately. Do you run poison 7.1? That particurar ROM I was using was problematic, causing the phone to overheat and the lcd problem was present all the time
Mine is completely stock and unrooted.

running completely stock & unrooted. Mine has this problem too. However, the image disappear after 10-20 minutes :|
I had this problem on my unit as well. Tried to adjust the white balance and it seems the issue was barely noticeable on the status and navigation bars.
The good thing is that screen retention falls under manufacturing defect and you will get a new screen.
Mine got replaced with a brand, spanking new one, but the issue has started to creep in just a little bit after a few months, but its very faint.
