Hey guys,
got my new s2 yesterday. But experienced a strange effect when waking up the phone from standby (black screen) by clicking the home button - when the phone then goes into lock screen for a short time. the point is, before the lock screen appears (after clicking the button), the display first gets grey/slighty lighted (for a real short time) and not till then the lock screen appears. it's sth like an intermediate step (for a trickle of a second) before the the lock screen appears. it seems as if the display have to lighten up first a bit...not really bright. as if it's dimming up..
how is that with yours? as i remember, my previous s2 went into the lockscreen directly (of course with the usual delay).
you can see this behaviour the easiest when you're in a darker environment.
thanks for your feedback!
btw. fw is kg1 with root-kernel. but already tested other fws..
flo
That's the way it is. No firmware has fixed the issue. Some users say in the latest KG1 the problem is gone but some says not. So don't worry.
u know what i mean? i dont mean the delay..im speaking of that little "pre-flashing" in the display...but its no real flashing cause its not very bright.
checked it again right now. that pre-flashing has some vertical stripes in it which descend to the final lock screen. looks like the lock screen pic would build up a little slower..
anybody know this effect?

Started this thread just to have idea about different versions of black screen bugs. Do we all have a specific definition or everybody has different experience and termed it as a black screen bug.
For me, when I used Paolo & Rome kernel with Adfad's N1 ROM, my screen went black whenever I tried to unlock and this was 'black screen bug' (for me).
hit button to wake phone to unlock screen laggs for 5-10 sec, with live wallpaper 2 sec.
when i get an incoming call..screens black, sometimes touching it lets me see whos calling.
when in call, i pull phone away from ear to see screen, ie call waiting, use keypad,ect. black screen, again touching it sometimes brings it to life.
those would be my 'BLACK SCREEN BUG" term assumptions

An easy way to recreate it is to simply turn your phone off and on real press power button the second it goes black press it again it will stay black when it is actually on
I have Speed Rom 5.1 on my Amaze. When I am finished with a call, the screen stays black. I try to hit the power button, but nothing happens. I have to remove my battery in order to reboot. Can someone shed some light on why this happening? I am thinking that it may have something to do with my CPU Tuner settings, but I am not sure.

Probably that or a bad flash, just reflash, see if it solves the issue.
Most likely it's something simple, like an issue with your proximity sensor. I know there was an app that could calibrate that but I forgot what the app was.
Stock Rom - Black screen while phoning
There is a similar problem on my wife's phone with a stock rom (not rooted Amaze from T-Mobile). When making or accepting a call, the screen will instantly go off even without leaning the phone against anything and won't turn on unless the power button is pressed. Sometimes the screen would turn on by itself after a while after the other phone was hanged.
I've downloaded AndroSensor app: the proximity value does't change even when touching the area near the earpiece. It keeps showing ( 0.5mA ) 3.5 in.
I've found a thread which is there since april 2012 and describes quite a similar problem.
okay.. i just the original post date for this thread.. please don't bring back threads that are 6 month's old which issues might have been solved already since no ones been posting in it for 6 months...
(anyways) this is what i was gonna say
on my current s3 when my phone is placed to my ear it cuts off the display.. and if you pass your hand anywhere near the sensor's to the top near the camera it cuts off the display.. maybe there's a feature like that enabled on the stock rom also.. or you could possible check with the system settings to see "screen" on/off settings in display or power saving mode.. or something...
Thanks for the answer. I didn't notice that the thread was that old. I think I will keep up a newer one. But the current issue isn't likely to have been solved.
The problem doesn't seem to be triggered by wrong sensor measures (because the screen will go off even after disabling the sensor) nor does it depend on the rom version (same thing on the CM10).
Resolved:
It will sound stupid but I have found a simple solution:
I have just wiped the screen in the upper left corner where the proximity sensor is located and it started behaving normally. Though I don't use any protection tape on the screen it seem to have become less sensitive because of mud or sweat.
Hey
Since ics, multiple one touch lock screen widgets dont work properly. The led will flash and the it goes to the lock screen and times out with some, and with others it stays on a very low ambient type mode. Any one else? Any suggestions, i love one touch to lock the screen, damn first world problems

The widgets support ics?
fixed
I just turned off the lock screen, hardly needed since there are only soft buttons on the front of the device, and it's unlikely the power button would be accidentally pressed in one's pocket. Then i used a cool app called screen off and lock, it even has crt effect.
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)

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."
Someone found kind of a solution to this, but it didn't work for me: http://forums.androidcentral.com/sa...t-rid-dark-filter-lock-screen-wallpapers.html

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.
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)
