Been noticing it on all variants of JB ROM: rasbean jelly, AOSP, OTA. When you lock the screen and expect it to turn off, it goes blank then flashes on just a sec before finally turning off for good. It doesn't matter how you lock it: could be using your power button, screen off and lock app, or the sleep button in notification widgets.
Any of you guys experienced this and figured out a way to solve it?
it happens all the time since the days of 4.0.4, the lockscreen flicker, there are ROMs out there with patches, and CNA doesn't have the problem, at least with my phone. it's absolutely normal, just a small software glitch, so nothing for you to worry about.

Has anyone else had issues with waking up the phone?
Every so often when I hit the power button to wake the phone, the screen turns on but looks super glitchy for a second or so, then shows the normal unlock screen.
When I unlock the phone, it instantly turns the screen black. The phone is still "on" as I can push icons, etc. If i push home the phone still vibrates but the screen will not "re-awake" unless I push the power off and on again. This has been happening quite a bit and is annoying to say the least. I also seem to be having in phone calls with the light sensor as the screen goes black just as I am about to push push buttons while I am in a call.
Is this just me or are others affected by this. I didn't see this issue discussed within all the other reboot/glitches threads.....
Mine is a little lagy when unlocking and occasionally I get a weird squiggly looking screen for a moment, then it is fine.
I assumed it was because I have a SetCPU profile set to 216 with a priority of 100 when the screen is off.
Mine when I unlock it it stays on the lock screen. The phone is still "unlocked", but it shows the lock screen and it doesn't change no matter how many times I lock and unlock. It is very annoying. I got it on CM7, Bionix, and the GB leak. I went back to stock 2.2.2 just because of this reason. Anyone know what it could be?

Click to expand...
Click to collapse
I just went back to 2.2.2 for that and many other reasons.
Working great

ok i can reproduce this on multiple roms on multiple phones,
symptoms: when you press the unlock button on your screen it flashes whatever you had on your screen prior to you locking it
how to reproduce
step 1: open up any app
2: lock the screen with the physical button
3 unlock the screen with the same button and it will flash the last thing you had open prior to locking it, then show the actual lock screen
4 without unlocking the screen, turn the screen off by pressing the lock button
5 unlock it again, this time because the last thing that was on the screen was the lock screen itself, it wont flash the apps screen, and the lock screen actually performs faster due to this.
ok, so here is my point, if there was a script the told the system to display the lock screen before turning the screen off and lock it, the wake up time would be significantly decreased. any thoughts or input?
what roms have you seen this on?
im on mosaic and cannot reproduce that. its the lockscreen as soon as i press the button.
on the captivate, stock, cm7, serendipidy, and andromeda,
on htc inspire, stock and rcmix3d, cm7
and it does it on nook color running cm7
Yeah, my stock rooted 2.2 does this.

I cannot reproduce on the Paragon ROM either.

cant reproduce it on Serendipity 7, I am using the SGSII lockscreen
seems like it comes and goes. does it some times, usually when laggier, but sometimes doesnt...not all the time though...
That's just the last image left in the static screen memory. It would probably take more time to clear the memory than to leave it there. It doesn't happen for me but I have the CRT anim installed, so it blanks it out before shutting off.
doesn't happen
on Nostalgia 1.5 with Glass unlock
Over this past week the back light for my Nexus S 4G appears to randomly shut off. Right now it has happened about 5 times and when I need to use it right then, preventing me from just stopping to investigate what may be causing this. The screen still comes on allowing me to quickly unlock using the pattern and then restart by holding down the power button. The one time I was able to investigate a little I was navigating into the settings menu when the screen just went blank. I pressed the power button a few times and could see the hardware buttons below lighting up as if the screen was on but that was it.
I'm currently running Slim Bean (Android 4.2.1) Beta and will be trying another rom but wanted to see if anyone else may have encountered this issue before I bring it up with that thread.
Yeah experienced this too in most 4.2 ROMs that I've tried. Some people say it's a bug with the auto- brightness settings but I don't buy it since I don't really use auto-brightness but still get the error. I'm back to 4.1.2
Glad to hear. I was becoming worried I had some hardware that was failing.
I will turn auto brightness off and see how it goes.
Thank you
So it has happened quite a bit since my last post. Even with auto-brightness turned off. I'm blaming this bug for my alarm not continuing after I snoozed it a few times. (I know they are unrelated but its just really annoying).
It happened again about ten minutes ago and I managed to output a bug report feature on 4.2.1. Not sure if it is of any use to anyone. Message me if you would like it.
While the phone is powered on, randomly the screen will not turn on for me. This has been happening for at least a week yet the only thing I can really recall doing with it is turning off some default apps recommended in another thread here. sometimes the screen goes completely gray as well.
anyone else having this problem? Ive been taking the battery out to resolve it thus far. I'm rooted with 4.4.2 installed (no roms)
Just installed Santod's NuSenSeven Marshmallow ROM and I'm not sure if I'm missing something with the security settings or it's just the way it is.
In older ROMs, I've setup the pattern screen lock to lock after 3-5 minutes of inactivity. If in between those 3-5 minutes I put my phone to sleep using the power button and press it again to wake it up, the standby screen appears and I just swipe to unlock it without inputting the pattern.
However, when I do that in this ROM, there is no standby screen but instead I get the page I was on when I put it to sleep.
It's not a deal breaker because I'm loving the ROM but just wanted to know if it's possible.
Bump. I am having the same problem.
