Hi guys,
when I try to unlock my device by fingerprint, when it is on lock screen, all the screen increase luminosity with a green light sometimes.
I don't remember if it's normal, because some days ago I got my display replaced... I also watched some videos and I didn't notice the increase in luminosity when they try to unlock the device in the lock screen.

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.

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
Hey guys, I got my phone last Saturday and have been playing around with it ever since.
I noticed that I had the night clock bug (whole screen is lit up) and as far as I know it's already a confirmed software bug. What I also noticed though was that my lock screen is also lit up. I'm using a pure black wallpaper which works well when the phone is unlocked (appears pure black) but the black is lit up when the lock screen is shown. It's almost like there's backlight bleeding. In the home screen and lock screen preview though it shows that it should be pure black
Here are screenshots of the "bug". I'm actually thinking it's a software bug since it was captured by the screenshot. http://imgur.com/a/p5maP (Take note the the blacks on the first image is different from the other 3)
Was wondering if this bug is related to the night clock bug or a defect with my unit.
If anyone is willing to help, kindly try changing your wallpaper to a solid black color and check if the blacks on the home screen and lock screen is different.
Thanks! (I have 4 days left until I won't be abe to replace my unit so I'm trying to make sure everything's good)
Bump. :crying:

They're referring to the Night Clock alone. I have that problem as well as a lockscreen problem. Haven't seen anyone reporting if they have the lock screen problem so I'm trying to figure out if it's a software glitch or a bug with my unit.
Basically the lock screen preview when applying a new wallpaper shows that the lock screen should have super amoled blacks but when I lock the phone the black is lit up.

If there's any consolation I experienced this very problem. Were you using fingerprint to unlock? I hadn't seen it because I had swipe to unlock.
I still haven't figured out how to fix it.

That's normal. This happens because the lock screen puts a slight filter on your wallpaper. It de-saturates the image. You can try with a solid red color, it might be easier to see.

Not, really. This only happens when you have Fingerprints/Pattern set up as your Screen lock type.
If you set it to Swipe, with the water droplet effect, there's no "filter."

Yeah it's clearly a bug, but OP thought it might be a defect of his phone. I was just reassuring OP that the problem exists in my phone as well. Thanks for that link. I did try the solution they proposed but it didn't work for me either...
Solution not working...plz another fix?
I have the same bug on my Galaxy J5 (super amoled), I use pin to unlock it. It is pretty annoying. I use the same black picture for both lock screen and background pic, and after unlocking the phone, black backlight turns off. Swipe to unlock solves the problem, but I have to take one of the disadvantages : either backlight or not locked phone.
Download "klwp live wallpaper maker" from playstore and make a all black wallpaper . Save it go to settings ---> background/wallpaper, set KLWP as lockscreen and wallpaper/background.
Not solved? are u using xposed? if so, download Bright Lockscreen and see if this helps.
Can I fix this? Thanks

what do you mean by "very dim"?! too much brightness or too less?
i see mine get like "auto brightness" like see the screen set itself more brightness and less when in direct sunlight with auto mode disabled...
thats what i know so far...your problem will be like the same i think?!
Too dark, it doesn't change to brighter as it did before

but in your brightness slider you can go to 100% brightness or you only can go to 90?%?
If you can go to 100 and anyway is too dark aybe you need to replace your screen because is faulty.

ah ok, fine...only now i see what your problem, i think is the screen itself and not the second screen, if the second screen is too dim is because the sensor on the side of the top speaker can be dirty on it and it doesnt detect the light trough it...
if this happen again to see if they are some dirt on it simple with your phone locked put it under direct light above that sensor and if the second screen gets brighter then is ok, if not clean the sensor.

You are right, it happens all the time, when I move the phone away in a call, the screen doesnt light-up, I had to press the power button, until I found that whiping that sensor lights it most of the time, must have very little sensitivity

for sure its the sensor...my second screen have a delay maybe 4/5 seconds when put in sunlight to be more bright and its clean! but this second screen in V10 arent too bright like in V20.
Also my call screen doesnt show up too when i need to end a call, i need to click on power button to wake the screen but i get used to it now.
when the phone's screen is off and locked, press power button and tap once on finger print logo (without unlocking), my screen start to blinking, it's like night mode on/off rapidly and goes away after unlocking

It's a camera under the screen. The reason the screen flashes is to take a picture of your fingerprint. It's not a hardware or software problem it's normal behavior.
How does your device take a pic of your fingerprint if it can't see it coz it's too dark

there is no problem with finger print flashes and I know how it works
but there is color distortion after touch and flashes and same thing happens when i use oled saver app as mentioned
see these 2 screenshots before/after (it's not that much dark on my screen but you will get the point)
Flashed Ace2 to OxygenOS A.08 and updated to A.10, problem still persists.
Happens both with auto brightness enabled and disabled.

Was this issue also present on ColorOS?
Disable always on display
Any unlock securities
Fingerprint, pin, code etc..
I haven't encounter any screen flashing
I have same issue, tried turning all off, did help, but i need fingerprint unlock... Autobrightness does not work at all, just dimms the screen a bit when turned on, and goes bit up when turned off, no changes in light or dark room
So i believe i figured it out, it is connected to always-on display features, which includes animation for fingerprint unlock. There is an option to turn off animation for fingerprint when display turned off, but then you have to turn on the screen before using fingerprint...
Also this phone gets pretty warm when only looking youtube or browsing, when on 120Hz refresh rate. I used setedit app to reduce it to 90Hz, much better battery life and no heat...
One last solution for the screen flickering, turn off always-on display, and turn off fingerprint animation only, it is under security/fingerprint/fingerprint animation setting, just choose none, it still litghs up the fingerprint, but has no animation, and most important, no screen flicker...
The same problem, flashing, removing the fingerprint, and using the pattern, the problem is gone
Yeah, it started again be me, so no lighting for fingerprint, and then works fine... Just turning off animation did the trick for short time

Yes, I had a region lock, after contacting the seller. It was opened with TeamViewer, now 3 weeks. There are no region lock messages.
So the seller could remove it? Mine keeps saying only oneplus can remove it. Did you what he did? I am nit sure if it completely removed or just blocked... The bigger issue is these software issues, especially flickering which could damage the screen... I wonder if these issues exist on all oxygen os phones, or only on these flashed from color os

So turning off lighting for fingerprint fixed the problem for good?
Yes, turning off any always on display features, which includes animation and lighting for fingerprint does eliminate the problem.. i suppose it is some drivers for AOD that are incompatible. Same goes for light sensor, if you test it with software the problem is obvious, light sensor does not work at all, it is recognized, but it does not react to light changes.
Hi All,
Could anyone comment on the minimal requirements to avoid flickering and potential random restarts? At this stage I turned off AOD, turned off fingerprint for locking/unlocking (only use pass + face recognition) and turned off the auto brightness. With these settings the flickering/random restarting problem is gone. I just wonder whether there is a solution with potentially fingerprint for locking/unlocking off, but with auto brightness on and with at least basic AOD on. Thanks in advance for your help!
Hi I have the same issue screen flickering and diming after turning one the screen with in addition and the most problematic the call is blocked by a message concerning the region.
If I make a factory reset the calls work work a time then the same problem comeback
i fixed screen flicker... show fingerprint icon off, Finger print animation off, AOD off. Auto Brig off
