[Q] Touchscreen not working on lock and reset screens

[SheenaIsAPunkRocker]

In the last couple of weeks, when the pattern lock screen is displayed, it intermittently doesn't accept touch input. If I power off and on the screen quickly, it then accepts touch input fine.

Similarly, if I press and hold the power button (with the phone on), it brings up a "Phone Options" screen, with options for Silent, Airplane, Profile, Reboot and Power Off. Touch input does not work at all on this screen. I'm working around this by using the Quick Boot app.

Otherwise, touch input works fine, so I don't think it's a hardware problem.

I've seen something similar when Google Nav gets in front of the lock screen. Touch doesn't work until I power off and on the screen, and enter the lock pattern. Could something invisible be getting in front of the lock and power screens?

Using Pongster's HyperDroid-GBX-v12 (2.3.3).

Hey there,

Maybe the ROM h doesnt function properly on your device. Try shifting to another rom. All are equally amazing. If you do not want to shift, try running task29 and start the process all over again

Have you read the thread about the unresponsive touchscreen, where pressing hard on the end call button fixes the screen touch? I assume your problem is in essence the same; once you press it hard enough to actually unlock the screen the touch works fine.

That probably is what the problem is. Btw to everyone, I haven't noticed a difference in pressing it really hard, I noticed that pressing it a lot of times does the trick

Thanks for the feedback. I don't think it's the ROM, been using GBX-v12 since it was released, and previous versions before that.

The symptoms do seem similar to the other thread, but others report it on many screens. I only get it on the lock and reset/power screen. Otherwise, it works fine. However, those screen are brought up after pressing the power key ...

I suppose if it is hardware, then it's likely that cable issue. If it's software, then a reset should clear it, so I might try an ICS ROM from scratch first.

I guess i shoulda commented that how my digitizer began acting, it only did it while in the power menu but after a couple days it started doing it while just hitting the power button to put it to sleep, so i remapped my green phone key to be the power button

Thanks for the tip. You're right about the symptoms getting worse, it now occasionally stops working on other screen

I'm using any button but power to turn on the phone. To turn it off I've added "Go to sleep" to the notification widget bar, which I assume is the same as pressing power??

Not quite as user friendly and sometimes I forget not to use power off, but it'll do for now!

Yes that will work! I used it cause I got lazy and didn't feel like changing the key file but it's much easier to use the green call key instead of the notification power widget

Try this:

Lock the screen normally, screen turns off.
To turn it on again by pressing any other screen buttons other than the power button.

I found that if I do it this way, the screen runs normal.
