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.

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

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

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.
I'm having an issue with my Nexus 5 after the 5.0 updates. I'm currently on 5.0.1 but had the same issue with 5.0. My device is completely stock. Just never felt like doing anything to the nexus 5. First phone I decided not to root. The issue i'm having is that every once in a while during a day I will try to turn on my phone to view any notifications or just refresh some news sites. Instead of getting the lock screen and hearing the unlock click to slide, i'm taking right to the home screen bypassing the slide to unlock. All applications at this point will glitch. For example, if i open hangouts, it will open but be blank. Spotify might open, or just be a dark gray screen. Other apps just behave very strangely. If I try to press the home button, it lights up and won't do anything. If i press the multi-task button it looks like it will show the running apps but then just shows a blank screen. If I press the back button many times, it takes me back to the home screen which might or might not be blank. The only way around this is to reboot my phone. But this is happening a few times a day. Often, i'll also see the home button and multi task button disappear. I've taken two screen shots of what it looks like. Has anyone ever seen this issue? I don't mind downgrading back to 4.x or rooting for a custom rom if that will resolve this glitch. I can also provide a list of installed apps if anyone wants to know. So what do you guys think of this?
Hi all,
When I'm using my month old Nexus 5 it will just randomly kick me back to the lock screen, sometimes I can just unlock it and keep on trucking but sometimes it will just immediately lock again or it will work for a couple of seconds and then re-lock. Once its in this state even a reboot doesn't always help and about the only thing I can do is get into recovery mode and re-flash it again. I used the Sensor Box app and have noticed that the light sensor is always reading zero, and I'm not sure if this is part of the issue?
This was happening on the PA Alpha, Stock 5.0.1 and since I was still having the issue I flashed back to 4.4.
The weird thing is that my phone had been fine for the 3 weeks or so I had it before hand. I flashed lollipop on it less than an hour after I took it out of the box and it had been running smoothly up until yesterday.
So a few questions:
Is there anything I can try to fix ir?
Can I use debugging to see what is causing the screen to lock?
Is this likely to be a hardware issue?
If it is, is there anything I will need to do to make sure I keep my warranty?
Any help is very much appreciated.
Bump with some other information:
I don't think its the light sensor, I tried using the phone in a pitch black room last night and the same thing was constantly happening, there was something else odd happening though.
From the restore of 4.4 I was on the "Select language" screen, whilst I could swipe and roll the various language options up and down the moment I presses "Next" the phone locked, if I left the phone on this screen eventually the screen would automatically lock and then it would keep locking itself constantly again.
Also, just for total clarification by "lock" I meaning "return to lock screen" not freeze up and become unresponsive.
Couldn't find any similar topic except in forums for s10+, OnePlus and other phones. Sorry if I missed anything.
As in the subject, after unlocking, approximately half of the screen flickers black and goes to the home screen. It takes less than a second. Always top half, bottom half shows home screen right after unlock. This does not happen on each unlock, but also, there is no pattern - it can be after 5 or 30 unlocks, it can be after 5 minutes or 10 hours of not using the phone. It started mid-July and not only annoys but is starting to worry me. Solutions from other threads didn't help. For example:
Fingerprint sensor problem - I don't use it, I have pin lock.
Samsung Pay issue - I don't even have it available, so, don't use it either .
Animations - setting them off did not help.
I cannot guess anymore what would be the cause, if it's some app which wakes up after unlock or what else. The only thing I've changed (except updating apps) was adding another sim card, but my tiny little brain cannot find connection. I didn't test removing it as I need this sim active and don't have backup phone right now. Also, I would really like to avoid resetting the phone...
Did you experienced anything similar?
Thanks a lot for any help or suggestion.
are using Samsung or some third party launcher. Did you wipe cache? Latest firmware updates?
Yes, I did both, firmware update and cache wiping, no change. I'm using stock launcher.
did you try in safe mode to exclude some app causing it
Yes, I tried safe mode without success.
i would take it to Samsung repair centre if pos
Thanks for trying and all the steps. There's nothing like that where I live, neither any advisory place except for hotline. I can drop it at their service but will need to wipe it down before, which I keep as the last resort. I'll keep waiting for another firmware update and if nothing changes then I'm willing to do the hard reset. I just hope it's not a symptom of some virus - I'm trying to be most careful, scanning device periodically, didn't root, so I naively count on being safe...
i don't think it's virus. fingers crossed it's just software issue
hi again, just to let you know, I think I know what was causing this flickering and now I feel silly . Home screen rotation. I had this option turned on, and it's possible that sometimes, when I put my phone on the table, home screen rotates to horizontal position. Of course it locks after few seconds. I've noticed it completely accidentally, because one time, when screen flickered black there was slow-motion rotation animation in the background (which I've never seen before). That's why flickering was completely random to me, not connected to any type of notification whatsoever. Well, it's not, it has a pattern . I've checked it plenty of times and each time I lock my phone with home screen in horizontal view, but unlock in vertical, half of the screen is flickering black. That's it, at least I believe it must be this, because it happens each time and never when I lock my screen in vertical position.
Once again thanks for all the help!
