Problems with lock screen after sleep - Nook HD, HD+ Q&A, Help & Troubleshooting

Having a problem with the lock screen in CM10.1 that is happening more frequently.
It seems it happens after I open the case lid and the Nook HD+ wakes up. I use pattern lock (but it's happened in the swipe lock also), and for a moment, it looks like it's unlocked. The desktop or app that was up when it went to sleep is there, but only for about 1 second. It goes right back to the lock screen. It repeats over and over. At first, I thought only a reboot would fix it and allow me to unlock it, but I found if I hit the power button to put it to sleep and wake it up, it typically unlocks. Sometimes it might need me trying that a couple of times, but it usually works.
Ideas? Anyone else having a problem unlocking after sleep? So far, I'm not sure if it's just lid-induced sleep or if it would happen after I use the power button to sleep it.
Again, it doesn't happen all the time, but i'm finding it happen more frequently.
Thanks!

I have heard about this problem from several people, but usually it is on an HD+ with the cover that wakes up the tablet. However, I just experienced this a few minutes ago and my Nook has never had a case on it, let alone one that wakes it.
It happened when waking it with the n button but after turning off the screen with the power button and back on with the power button, it worked. (not turning off the Nook, just screen off and back on)
So it appears that it is not only the magnetic wake up that causes the issue.

Mine does that too. I thought it was a hardware defect, but I tried another one and it does exactly the same thing.
So far it's only happened with a case-induced wake for me. It happens regardless of whether I sleep it using the case or the power switch.
The lockscreen loop stops if I sleep/wake it using the cover consistently, but it doesn't go away if I sleep/wake it using the power switch, oddly.

same problem with no known solution

I have the same problem and no solution. I wonder if a newer release of CM would help.
Also, in regards to temporary coping, when this problem appears is there a method (besides reset) to deal with the problem. I noticed that sometimes I can eventually get past the lockscreen without restarting, but I'm not sure what causes that. The best solution I have for my wife at this point is I delayed locking-after-sleep to 30 minutes.
Two-user set-up (my wife and me). I am fairly new to the scene--first time I ever loaded CM on any device. I recently bought the HD+ from Best Buy for $150. I tried to follow the verbatim instructions from e.mote titled "[NOOK HD/HD+] Installing CyanogenMod 10.1 for Dummies." I haven't used custom ROMs much since my heady days with my Palm Pre.

I'm in the same boat. Hd+ running CM 10.1.3. I wonder if this still happens on the 10.2 builds...

While on 10.1 this happened to me every time after charging (well, maybe not every time, but that's when it happened...), but if I just turned off screen and then back on I was fine until next charging.
I put on 10.2 earlier today (from Iamafanof site, so not from here). Will be interesting to see if the problem is till there, but I won't know tat for a while yet.

Im seeing this on both 10.1 and 10.2 on my nook HD no cover.

I'm seeing this even without a lock screen. The screen turns on for a second, after that turns off. After many tries it works or after a restart. With lock screen it is the same as above.
Happend on CM 10.1 and CM 10.2 with a cover

So there's no solution to this problem and you just have to reboot it?

You just close and open the cover again

I'll try that again but I don't think it worked.

I have been having the same issue as well with mine. Just curious if really has been a solution to this?

No it is a hardware issue. There are two options close and reopen cover or cut magnets out and turn on manually. I don't think anyone has tried more powerful magnets if you want to test that it would be helpful.

I kinow its an old thread, but I Fixed it by closing and opening the magnetic cover, rather than using the power/off/on screen button and it worked.

Only fix is to do one of three things. Remove the magnet from the cover, remove the cover is self, disable the lock screen. It's because the cover and lock screen confuse each other and it has the cover wake it, then the lock screen sleep it, then it sticks. It's very well known, and nothing to panic over, just really freaking annoying.

[Q] My screen taps/touches/clicks itself

as the title says i was reading when the menu started showing and hiding again and again i tought was some book issues but when i got to the homescreen it began to run apps i had on it, i have no idea of the cause of this problem
I've had this same problem. I believe it's just the software and not a deficient screen. If you look over on the nookdevs website, there's a page about recalibrating the screen. I've tried it a couple of times and it's definitely improved it. Every now and then something wacky happens, but I guess that's to be expected when you let B&N develop for Android.
I had this happen myself once, and it was pretty annoying... If I didn't have adb available I don't think I could have fixed it until I did. I wasn't able to tap the screen myself, it was taping all over the place.
I did manage after a few minutes to get multitouch paint installed and it was drawing weird dots, lines, angles, etc...
I now have the recalibrate command in gscript but not sure I could run it while it's acting up. Luckily it's only happened once, and it happened while plugged in but never seen it happen again.
Happens a lot on my NC, and I think every time its because my kids touch it with dirty fingers (sweets, chocolate etc), smearing small amounts of dirt on the screen.
The screen goes nuts within few seconds, thinks its being clicked etc...
Wiping/cleaning the screen helps to resore normal behavior, btw - while the screen is moist it does not work for me at all...
Ordered screen protectors, lets see if it makes a differencel
My screen randomly goes nuts as well. It seems like a sudden, rather than a gradual thing. The screen sometimes gets pretty dirty, but cleaning it didn't seem to make much difference. Odd thing is, what DID make a difference was taking it out of the aftermarket case. I have no idea why this would work, but it does. One thing this case does is that it pushes the power and volume buttons in, as it uses four elastic straps at the corners. Maybe holding these buttons a certain way recalibrates the screen, and if you're touching it at the time, it freaks out?
I've noticed my screen only bugs out when I have it plugged into the charger.
As long as its unplugged, its fine. As soon as i pop in the cord, the screen goes haywire.
Only the wall charger though, not when its plugged into the USB on the computer.
My screen was doing that until I got a screen protector.

Also, if you lock and unlock the NC it should stop acting funny.
I noticed that too. Mine hasn't gone REALLY nuts since I took it out of it's case, but sometimes when playing angry birds, it freaks out to the point where I can't play. Hitting the power button, and then hitting it again, and unlocking makes it normal. Wouldn't that indicate it's software instead of hardware? Maybe there's more than one problem?

Mine does the same thing every now and again. And like you, locking the screen and waking it back up fixes it every time. It's definitely software related.
Do your cases have a latch? With a magnet? Because I'm starting to think that may have something to do with it.
My case has a latch, but the magnet is not against the nook when I'm using it..

Heh, I've considered that.. Also considered the mystery sensor to the left of the Nook button too.. Nook is afraid of the dark.
Seriously though, with the CPU guvna' set to ondemand and wifi turned OFF before I power it off I haven't seen it reboot yet. It rebooted once yesterday and I know it had wifi left on as I had just been using it and didn't turn it off before it went to sleep.
So totally making up numbers here....
Default CPU governor + wifi on = 30% chance it's gonna reboot when it goes to sleep..
ondemand governor + wifi on = 20% chance it's gonna reboot
ondemand govenor + wifi off = <10% chance it's gonna reboot (not gonna even say 0 here.. heh)

I tested this theory. When the Nook is in the case, I get crazy screen taps when i try to type something. Out of the case, its perfectly fine.
When I just rest the Nook on the open case (not inside the straps/holders), it will also get crazy screen taps.
One thing to note is I also did not have any problems before updating to 1.0.1. Not saying the update is the cause of the problem but its one of the variables.

Weird glitch

I just recently got an HD + and put CM 10.1 on it. Every once in a while I get this weird glitch when waking it up from sleep. I get the home screen with the unlock button in the center per normal, but when I try to swipe to the right for the desktop icon, the screen flashes once then goes back to sleep. No matter how many times I try to wake it up this way it just goes back to sleep. I fixed it the first few times by rebooting but this morning when it did it, I tried swiping to the left to the browser icon and it worked. It brought up the browser and I just quit out of it to get to the desktop.
Anyone else have this happen?

Lots of folks see this. It is usually caused by your case with a magnet in it to turn the screen off. Just open it twice.

Thanks Leap. Didn't even think of the case being the culprit. Thanks for the info. I didn't even know the case had the feature until I got it.
I was thinking the Nook had a photocell that was reacting to opening and closing the case but it's a magnet that does it?

Anyone have screen flickering issues with their HD?

My HD (running 10.1.3 stable) has just started behaving strangely when I wake it up from sleep. The screen will flash then go black. Whether I push the Nook button or the power button, the same thing happens. It may do it 2 or 3 times before it comes on. Started doing this yesterday. Just now, it would not come on at all. I see the screen for a half second, then it goes black. Just wondering if it's already toast or if this is a known problem with a remedy.
Probably software issue.
If your using a magnetic case (problem)
You could try disabling the lockscreen if its enabled.
Daydream could in my theory affect that time frame.
The backlight should last years longer. The gpu should as well. I can't think of any other hardware issue.
If you have an sdcard try cm11 [or the bn rom] and see what happens. OR full backup of current rom in cwm and flash cm11 to internal. Clean and restore 10.1.3 and be back to right where you left off.

Yes I have the same flickering issues when trying to wake it up from sleep. I would have to press either button numerous times to get it to stay on and not black out. I'm on the same 10.1.3 stable. I am using a magnetic case but it happens without it. Before this happen, my slide to unlock screen would act up by not unlocking when I slide to unlock; it would just go back to the initial lock screen. Slide to unlock would not work so I turn off the lockscreen, now experiencing blackout screens when I try to wake it up by pressing either buttons. This problem happens infrequently but it is annoying.

I learned from another post that if it does not awaken when the magnetic case is opened the first time, close and open it again. This works for me 95% of the time. Sometimes there's 2 or 3 second lag but it almost always comes on.

Works like this on my HD+, too. Sometimes requires opening case cover twice, but the screen always comes on.

[Q] nook hd+ turns off after long period of sleep with magnetic cover CM 10.1.3

I have the same problem as others that sometimes after sleeping with the magnetic cover, even with the correct password I could not log in. I have delayed the screen automatic lock to 30 min and usually have to fix it with a restart if it happens.
I have another problem that if I have the nook covered with the magnetic cover for a time period longer than 2 hours. It seems to have been turned off. I have to try holding the power button to turn it back on and it will go through the nook splash screen and then the cyanogenmod start animations. Is this something expected with cyanogenmod? Has anyone else experienced this?
If it's a bug, I am wondering whether updating to CM 10.2.1 will fix it. I have read the first problem cannot be fixed and it might be hardware related. Is the second problem hardware related too? Thanks,

You need to open and close the cover twice. It is a known bug on all CM versions.

Hum, I can't seem to reproduce my second problem for the last two days. The symptom was that when I tried to press the nook button or the power button to wake it up, nothing happens, it stayed at the black screen. I guess basically what I did was holding the power button to shut it off and then turn back on. I guess it might have needed a second time of opening the cover. I will keep watching and see whether this is the case.

**HELP**Lock button permanently locks

I have a strange problem, well a few. If I lock my phone (C6903) using the physical button I can't unlock it again. I try for about 5-10 minutes sometimes and it just wont work. If I hold it down I can feel it vibrate as if it's bringing up the power menu but the screen just stays black. Eventually it will randomly wake up then I can play around as normal. If I leave it to lock itself I can unlock every time, fist time no worries. This is what pointed me to it being a SW problem rather than a hardware problem.
I also noticed that when I do have the screen turning off in the dark, I can see that the screen is still lit up! Just it is black, not completely asleep. It's really quite bright when I have it next to the bed. Also when I am outside I can't see the screen at all really, even with the brightness turned right up.
It's really strange all these happened about the same time. I figured maybe it was a ROM problem and a fresh install of stock ROM would help. Tried it and at first most of these problems went, just the fact I still couldn't really see the screen in the sun. I tried another ROM and at first was just the same but then these problems started again.
Has anyone had any or all of these problems or got any ideas what it could be? I am left thinking now that the problem is more likely hardware related as the problems are so sporadic and happen whatever I have installed.
Any help / suggestions would be appreciated but I have the feeling I will have to just admit the phone is dogged
You say that most of the problems desapararecen to install a new ROM, it is likely that installing something extra to be the cause, I was introduced me something similar with Expoxed Notifications Module.
Try a clean installation without installing test applications to determine if the problem recurs.
Thanks, yes I guess I will try that, bit of a pain having to reinstall apps after every install and restoring messages etc so I might just put up for now.
I also have realised that the screen not turning on and the screen staying on but black happen at different times. i.e. I can now randomly turn the screen on and off no problem (don't think I have installed or deleted any apps or changed anything), but the screen stays awake when off. When I was last not able to turn the screen back on after turning off the screen actually went to sleep. Very strange
