Hello, my first post!
I won this phone on eBay for 23 dollars. Seller mentioned that it is fully functional but screen flickers.
I tested the phone and is fully functional. The phone is in pristine condition with no water damage.
I tried everything to try to get rid of the flickering.
-Updated it to stock Marshmallow. Still flickers
-Unlocked bootloader & flashed a custom kernel/PEXO ROM by EHSAN™. Still flickers
-TWRP wiping didn't help
-Disabled HW Overlays in Dev Options. Doesn't help
Here's what I found out though. The phone doesn't flicker when it is only displaying text, ex. Settings menu. It'll only flickers when it begins to display images such as when I'm in Chrome or changing wallpaper.
WHEN NAVIGATING ON PHONE FLICKERING IS TRIGGERED BY IMAGES, PHOTOS BUT NOT WHEN DISPLAYING TEXT ONLY
It isn't random at all its being triggered by something
Does this have something to do with the hardware itself? Can it be fixed?
I had same problem with you

Hello,
the following problem appears when i try to unlock the phone after some hours: i can see my home screen, but the screen stays extremely dim. When i try to start an app (e.g. browser) the screen turns black. I can unlock it again, but the screen stays dim. after some unlocking the screen becomes normal (normal brightness) and also the apps are startable.
i am using autobrightness, the stock firmware, 4.1.1 (i9300xxdlih) power saver is not turned on.
thx, i hope you can help me solving this problem

i updated mobile phone to android versiopn 4.1.2. this morning. Unfortunately the problem still appears.
Maybe its a hardware defect?
Try to disable somehow light sensor and change settings to non auto brightness.

i disabled auto brightness and set the brightness to the highest level. But its still same: very dim and after a while a black screen; after a few times of unlocking, the display works normally
I have just seen the same issue on a friend's S3.
Anyone else? I feel like this is a very big issue that is still lurking in a lot of devices.
I tried it myself and I toggled the power button to turn the screen on and off.
It doesn't take long but sometimes when the screen turns back on, it's super dim and you can faintly see the lockscreen image.
You have to cycle the screen several more times to get it to the 'correct' brightness, and no it is NOT a brightness setting.
It's some hardware issue in the phone.
Sorry for the necrobump, but I only found this thread. I have this problem too since about a week back. It makes my phone useless at times. I first thought it was a software issue. I have an app (called Twilight) for dimming the screen more than normal settings and also toning it, for nightime use, and I thought that was the culprit first, but nope. I have flashed rom, recovery, wiped all caches I can think of. Still happens, just now I was in the middle of installing android revolution hd, and the screen ultradimmed on me so I can't finish the process
Thing is, a few months ago I managed to crack my screen by way of gravity and concrete. I let the samsung brand service centre in Stockholm repair it for me (it is out of warranty) and this issue with the dimming never happened before that. Then again, it didn't happen directly afterwards either... but still. So, I am thinking: either me dropping it caused more damages and this is because of that. Or the service center did a bad install of the new screen. Or, the replacement screen that was installed has a defect in itself. I am leaning a bit towards the third explanation... maybe different batches of screens?
Does anyone have any ideas? If I am to contact the service center and complain about their work I would like to be able to point towards a "known problem"...

Take it back, if it didn't happen before then the new screen is most likely.
It isn't a common problem
Hi, I have an xperia sola with ultimate rom v10 and experimental kernel v7. I just noticed this issue so I don't know if it's related to them or not.
I don't know quite how to describe it but I'll try. When my phone is booting (the sony logo) and when I'm in CWM, I see the ghost image of my phone's homescreen on top right and left. It's a silhouette of the time, the battery percentage and the notification icon. The image always changes to the last state when I experience it (for ex. if the time was 17.12 before I shut down, the silhouette says 17.12 too).
There is no ghost image whatsoever after the device boots though. I've carefully checked it only occurs when booting and when in CWM. Is this an issue or I'm just making a fuss over nothing?
Hi dnilbia,
I noticed your problem on my Sola with stock not rooted 2.3.7 GB! I can see the time and avast antivirus logo on the right and leftt top off the screen (where notification bar is),when my phone is booting or is charging powered off!Moreover on the left and right bottom of the screen there is a blurry small black "triagnle" (the edges of the screen).
Well seems like a problem of old lcd screens with lcd persistence image but maybe it is caused from moisture and low temperatures!Well mine disappeared some days ago,boot per boot it was disappearing a little bit til it was gone.I left it in dry environment and avoided using YT cause screen is always on!
Hope it is nothing
Hi, recently i faced with weird graphics problem - when UI loading there is two screens and they in pink/purple colors. It seems like GPU problem but recovery and native boot screen (When Samsung galaxy s3 text) all is good. But after beginning of CM loading and further there is two same load images in two top quarters of the screen, other two quarters in bottom is black. And such strange behavior continues even when phone fully loaded graphics UI.
Anyone faced this Issue? How to fix that?
PS: Touchpad is working even on black empty bottom half of the screen
PPS: I've wiped data and all is going fine. But reason of this bug remains unclear. Question is closed
For a week or two now,* I have been having some funny things happen with my Redmi Note 4 (Qualcomm, Global) phone.
Before that it had gotten water in it and basically shut down entirely, but they fixed it and got it up and running. When I picked it up they showed me watermarks on the screen, saying that the screen had frozen only once but that it may just be lagging.
Since then I have had a few symptoms of an issues, perhaps hardware issues, but potentially something that I can fix without paying more for parts.
Here are the things that happen:
- Music stops suddenly (screen on or off) and the music app has to be reopened (DoubleTwist, Miuiu's Music app, etc); Somes while in Doubletwist, if I click to visit home screen (square button) than the music stops. (this is the first issue that I noticed).
- 1-2 seconds of white screen before already-open apps appear after selected; Sometimes problems with apps loading or screen goes black when loading
- When closing apps or returning to home screen, it looks like the desktop(?) background comes up and then a second after is is re-populated with icons as if system is refreshing the home screen
- Once any of these issues begins, it usually worsens and the cell phone gets slower, behaving more and more strangely until not even useful to me; Reboot clears it right up for an hour or two or whenever this wierd stuff starts to happen again
-It seems like if I make a point of using the phone modestly, slowly, I can avoid these issues from starting up
- Sometimes reboot rometimes hangs on initial black loading screen
- Sometimes if I hit the power button to turn off the display, I can not turn it back on with that button (neither does the battery-dead orange light flash), so I have to reboot.
-When I turn the phone screen off while it has been working fine, I come back later, turn on the screen to find that it is now on the boot logo screen and it stays until I hard-reset the phone.
So, these are potential issues I have guessed at:
* Screen damaged? So far, other than watermarking at the top and some backlight bleed, sensistivity is perfect on the phone, and symptoms involving screen always seem to be triggered more by apps or pressing buttons.
* Apps or Android corrupted/internal memory damaged? I backed up via Settings and did a Hard/Factory Reset, then restored from backup. I still have the problems.
* RAM partially damaged? I test RAM with two apps and none of them showed issues. Namely my available RAM and used RAM reported always add up to the 4GB my phone has.
*Other Hardware Components failing? I used 3 apps to check all of the hardware devices and sensors that I could think of. Vibration is the only thing that does not work, and honestly, I don't care much about vibration.
Today I have suspected that settings may being at fault, and/or battery savers turning off my audio. Battery savers often identify my music apps as using "excessive amounts of power," perhaps because the speakers at involved, but it does make me think... I removed any battery-related and security apps, then turned off all battery saver options in settings earlier today. In 2 hours of music listening after that, I have not had any shutdowns, but I am not convinced I have solved the problems. In the weeks after this, the issue is back and the audio issue is always followed by the phone operating very sluggishly.
I have done a factory reset and restore, and the issue persists. Do you think there's any point in trying to do a clean reflashing of MIUI? Could it be a software issue or definitely hardware?
What advice can you give me?
Thank you for reading.
You can try booting in safe mode and then check if the problems still persist. Other than that, I suggest you to get advice from senior members of the forum.

Miui 9 does not have safe mode to boot in.
Hello,
Please watch the short video.
I got screen flickers over every app. Sometimes when scrolling, sometimes by itself.
My device is rooted and unlocked BL, latest miui 9.
When I enter TWRP the flicker is gone completely, even when scrolling through logs. I figure it is not a hardware issue.
Tried flashing everything from zero with MiFlash but the flicker remained.
Any ideas?
