[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.

Touch screen going crazy

The random bottom part of the phones touch screen starts to be randomly pressed,
It’s like the phone has a mind of its own, sometime is a few phantom presses and others it’s a full battle to keep the phone from random opening apps and calling people till I hit the lock button or pull the battery.
I have seen a few post about the phone over heating causing this, at 1st it seemed to be my issue, but now the phone does this while feeling relatively cool and right after removing the battery for a bit.

Nook touch misbehaving and pages turning on its own

Hello guys,
I am having this more than an year old Nook HD+ .It is rooted but on stock rom. From past 2-3 weeks i am experiencing problems with it.The pages are turning on its own in Epub and automatically randomly the applications open without even touching the screen.An i observed on left side near the corner of the screen the touch isn't working.My password has the letter P in it and that side the touch isn't working.Sometimes during random moments it works.
Really annoying. I disregistred the device and registered again....Same problem persists.
Any solutions ??
Thanks.
Do you use any screen protector on it? Did you try cleaning the screen?
It looks like a defective digitizer.

Touchscreen goes crazy at random times

Hi guys,
So I had to replace my broken screen.
I replaced and everything was working fine until one day, after 1 month, I start getting some ghost touchs in my screen.
There are some spots that triggers the touch at random times and keep pressed.
I've attached a screenshot showing one touch, that of course it is not mine, but keeps pressed for some reason.
If I press that region very hard sometimes the ghost touch disappear which leads to conclude that something is wrong with the screen that I bought, BUT if I reboot the phone it also fixes it, and that is what bothers me the most, I think it is not a physical problem but a software thing.
Can anyone help me break down this problem?
solution?
Do you had any solution for that?
Was it a hardware or software problem?
Best regards,
Spasshawwe

I have some issues with my Nubia red magic 3 and I need some help!

1) The Nubia 3 trigger pads stopped vibrating. i'v be using this phone for awhile and every time I turn on "gaming mode", the trigger buttons on the side of the phone would vibrate. One day, i was playing and the trigger buttons stopped vibrating. I'v tried everything to turn it back on and i couldn't. I would like some help to figure out if theirs a way to turn it back on.
2) The screen blacks out. The game I play is Call of Duty mobile. Nothing happens when I play multiplayer, but most of the time when i play 2 matches in Battle Royal, half way through playing, the phone starts to overheat quickly and around 37°C (98°F) or 40°C(104°F) the screen turns black. From there, i have always have to get out of the app and re-enter the app to work, but it keeps doing the same thing. I know it has to do with the temperature, but is there a way to fix it. I don't know if its the Performance Mode or do I have to lower the quality of the game, do i have to remove some space for it to work properly?
I would be happy for someone to help me resolve this issue
Try factory resetting your phone and make sure you've updated it to the lastest update V1.2
That's not suppose happen 37°+ and 40° is not heating near overheating 45° is. it could be the game one I left my phone under a pillow with game mode on with call of duty it didn't black out but it was 49° most likely you have to reset your phone. It looks like a software issue.
Can anyone help this boy please?
I also have same issues and sadly they cannot be solved I hv tried everything.
COD has this problem my many friends have the same black screen issue and on different phones
Also 40 C is normal +42 C is overheat.
my touch buttons also don't vibrate but that is perfect.
