[Q] 5.1.1 Lock Screen Not Appearing or Locking Consistently - Nexus 5 Q&A, Help & Troubleshooting

Prior to 5.1.1, every time the phone was idle for a short period of time the lock screen would appear and, when I was home, SmartLock left it unlocked, most of the time, but it always appeared. Since upgrading to 5.1.1, the lock screen rarely appears anymore and, when I’m away from home, since the lock screen rarely appears anymore, my phone is often unlocked and unlocked without a lock screen and having my phone unlocked is a big security issue . I don’t know if this is related to 5.1.1 or, perhaps, a recent Google Play Services update (since Google Play Services is responsible for so many things nowadays, I assume it’s suspect).
Anyone else have this issue/know of a possible fix? Thanks.

Bump. Is no one else having this issue? The lock screen for everyone works perfectly on 5.1.1?

Yes, since 2 weeks ago. Any solution?

None that I know of—I still have the problem.

Just chiming in to say this issue appears to be largely resolved since Android 6.0.

Resolved? Apparently not that largely. Such issue started 24 hours ago on my 6.0.1 device. Unable to lock screen despite pattern (or whatever chosen) is correctly set. No "smart lock" option is used, BTW; Though lock screen often appears but only when shutting down and restart the phone, not by rebooting it. Looked exhaustively for a common fix, but everyone suggests the same old, clear caches, credentials and device administrator thing.That is NOT working here. Safe mode says nothing's wrong with apps causing the flaw either. Yes, I'm rooted, on Xposed and all that stuff, as always. Probably it is related somehow; however, issue has never ever showed on any other device I had, and I had two previous on 6.0.1 as well. If anyone has a different hint on the subject, well it'll be well appreciated.

Random reboots mostly after unlocking, am I the only one getting them?

Sometimes I unlock my phone and the screen remains black, then the phone reboots but weirdly it doesn't ask for the SIM pin number. Other times I notice the phone reboots by itself and I notice it because obviously the screen lights up during the boot animation. This happens very rarely, so far it has happened about 3 to 5 times in a couple of months but it's still mega annoying when it happens.
Does it happen only to me? Is there any way to troubleshoot this issue?

If you provide some logs then maybe someone can see what is happening....
Or even basic information, like the configuration and setup of your device.
Right, forgot my configuration. I have an unbranded Z3 on latest Lollipop (but I recall I had a reboot also on Kitkat), no root, no weird apps like task killers or antivirus or anything like that. Sometimes it just does a reboot by itself, but doesn't ask for pin number so it's not a full reboot.
How do I provide logs again?

Factory Reset can solve ur problem /based on personal experience
I did that already less than two months ago and I refuse to believe I have to factory reset this thing every month to get stable operation. Also I'm not even rooted and I haven't messed with the system itself so why would I need to factory reset? Factory reset implies that there is something that has changed and needs to be re-set, and I haven't changed anything special that would require such a drastic solution. Not having done anything special, the issue would come back sooner or later if I don't spot the real cause.
Anyway, in diagnostics I have 21 application incidents for systemUI... Could it be caused by a bugged theme? Does this happen to anyone else?
Today I had two and I had another one last week. A off these were weird half reboots like I described above. I only noticed one because I was at my desk and the phone lighted up for the boot animation.
These reboots show up in diagnostics (phone info menu) as system events. Can you please check out if you have any system events and post here? I want to know if this is a widespread problem. Post here if you have any and also if you have a solution or way to troubleshoot.
Nobody at all? Really?

Screen time out not working

has anyone run across this issue when you set a specific time out, the screen dims after the specified time but does not lock, it stays on?
my phone was working just fine, stock not rooted, took the latest update and after that i've been having nothing but weird issues, the other day the notification area at the top was not working, i had to basically check every app, messages etc manually to see updates, had to factory reset the damn thing, now this screen issue, the phones is only 1 month old.
any input?
thanks
I'm having very weird issues with screen lock. I'm be on the phone and the device will randomly lock and not let me unlock it without restarting the phone.
The new update is when it all started. I don't want to do a factory reset, but it's looking like I might have to?

Hey Chavalier
Thanks for your reply.
I can do that but is there any alternate solution available to avoid formatting my device?
Same Issue
I'm not sure what carrier that you are with or if that even has anything to do with it. But I am with T-Mobile and I initially received the update a couple of weeks ago and right after my phone updated I noticed that my messages would no longer appear on the edge screen. Everything else worked just fine except for that. I called T-Mobile and they had me do a factory reset (which always sucks). After the reset the phone worked just fine for a couple of hours then went right back to experiencing the same issue. I called in again and this time they suggested sending me another phone because it sounded like a hardware issue and she also told me that no one else in her department with the same phone had any issues with their phone after the update (how true that was or if she really even asked anyone I don't know). So I called back in yesterday and the guy suggested that I do not install the update and just bypass it (I didn't like that idea at all but I figured I would give it a try). So now the update updates on it's own and I can't even bypass it. So after a new phone, 5 factory resets and plenty of frustration I still can't receive my notifications on my edge screen.
Please someone help!!

"Hi guys. First of all, i registered specifically to tell you of this solution. It's a very frustrating problem, im not sure if it's a bug too...
Ive tried factory reset, clearing cache (all three times, though it's probably a bit useless considering I'm not rooted/flashing custom roms).
As most people realize, this works until you restart the phone or randomly in the middle of the night as the phone goes into deep sleep mode.
I've tried disabling, enabling apps to no avail.
This is the solution my friends...
Go to settings->sounds and notifications -> notifications on lock screen change to show contents.
You may need to restart the phone.
And notification is back.
Im not sure why this is the case (i have fingerprint lock enabled), but i think this is done for privacy purposes. It will be silly if you had notification hidden then it comes up on the edge screen. So when you have notification hidden, the bug is probably that ALL notification is hidden.
Let me know if this works for all of you!"
It worked for me! Hopefully it works for you too! The only drawback is now everyone can see your messages on your lock screen. But at least it's back (sort of).

So do you guys prefer 5.1.1 over 4.4.4 despite the issues? Are you have any issues anymore?

Hi
I am still facing a small issue with the phonebook as if I am scrolling through the contacts for quite sometime, the screen refreshes suddenly and take me to the Homescreen. Other that this no issues at all.
Since updating my Edge 915S ota to 5.1.1 I don't get LTE connection anymore, it only shows 3g.
Can you please advise how I can get LTE/4G back?
Many thanks.

Marshmallow problems with spontaneous launching of Google Now, taking over device.

My phone has been misbehaving since it upgraded the OS to Marshmallow. It was primarily occurring with the Google Now app and it would take over the phone and flash up and off the screen and whilst this was going on, the phone is busy vibrating, the screen became unresponsive and generally I couldn't do anything with it during these episodes. I stopped it sending to the screen and then it was the Google app that kept flashing up, starting with a round circle coming from the app drawer icon. It has got worse over the last few days to the point that it might take me ten minutes before I could get access to the caller to make a call and even trying to shut down the device was near impossible because the confirmation box never stayed on the screen long enough to answer the question and then it didn't come back. Yesterday, after many tries to restart, it finally restarted in safe mode. If it was related to an app that I downloaded, it should have stopped then but it didn't. When I was able to get into settings, I then went to apps and then disabled google app as this was the one starting up and flashing the screen non stop. I was then asked if I wanted to replace it with a factory version which I did but I also left it disabled. The problem has continued but not as ferociously with the screen becoming unresponsive at times while the buzzing from the vibrate still occurring. I have looked up various forums but haven't found any that have similar problems described. I checked the screen overlay settings and they are enabled and that seems to be the main problem with marshmallow. I'm looking for some advice but realise that this might be too basic for this forum?

When you updated to Nougat, what method did you use to update? Did you update via OTA? We're you rooted when you did it?
Have you tried booting to recovery and factory resetting and wiping cache then rebooting?

It was an update that appeared on my notifications and I thought it was a small bug fix update and didn't realize that it would replace the entire OS. I just allowed the update and then realized what had happened. I think it is Marshmallow that it updated to but originally the app drawer was paginated and accessed by side swipes whereas the system now is a long page of apps moved up and down. I don't know if it was rooted and I assume that that means it wasn't.
I was trying to avoid a factory reset but I did wipe the cache and rebooting. When google apps is disabled, the interruptions are less often and not for as long but it still went into a complete meltdown of a screen appearing and disappearing at such a rate that nothing can be done with it. It won't show a video because of the interruptions.

Unfortunately, I think you're gonna have to factory reset in stock recovery because there's obviously a conflict with something you already had on the device and it isn't playing nice with something that was in the update.

Thanks for taking the time to respond. I have resigned myself to that although it does not seem to be anything that I downloaded to the phone as it occurred in safe mode too. I was just hoping that there was a fix out there but obviously it is not a widespread occurrence.

It could have been something in system that got changed during the update but the data from before the change is still there and conflicting with whatever changes were made. Some kind of saved system data that can only be wiped by factory reset or reflashing.

I did a factory reset, lost a lot of photos that had started being saved on the phone and not the sdcard after the upgrade to Marshmallow. Have had to accept that but unfortunately the bizarre behavior did not stop and it continues on and off, sometimes so bad that I cannot dial a number on it and other times it happens but I can get in between the action and dial or send a text etc. I have gradually been stopping things like notifications from google apps and traffic reports from google maps (this may have had a good effect) and anything that might be doing constant checks. It seems to have quietened down over the last day or so and I even got to play a game on it but the next option is to send it away to an engineer. I just thought that I would let you know the outcome of the factory reset.

Lock screen issue post Oreo update

So I have updated to Oreo through the OTA update.
Essentially no issues except...
Intermittently the lock screen actually locks up or when you wake it from black and locked the screen just keeps flashing up and off making entering my PIN impossible.
The only solution is to restart the phone. Then maybe 8 to 10 or 15 unlocks later and it does it again.
I'm on Vodafone AUS Galaxy S8+ (SM-G955F)
Samsung was like oh we have to either do a reset or uninstall every app one by one to work out which third party app is the problem. Surely there are logs they can look at. Language (or script issues) meant when I called they got me to boot into "Safe Mode" and said if you can log in here without issue then it's a third party app issue, despite me saying it was an intermittent problem and despite the fact that the problem is before logging in past the lock screen.
Is there logs I can get/look at that can help determine the actual problem?
Anyone else had the problem and know a fix?
