touch screen not responding

[Joost]

lately the touchscreen on my T-Mobile MDA sometimes stops responding, sometimes after slowing considerably. Up till now I have been able to get it going again after (several) soft resets, turning it on and off and fiddling around with it in general. There doesn't seem to be much of a pattern to it though.

Does anyone experience the same problem and/or know what might cause it and how to fix it?

Thanks!

Too many programs running? X doesn't close programs, it just minimises them.

U need the file tpenable.exe (you will find it in external rom package)

I'll give that a try. I assume it will explain itself as to how to use it.
Thanks a lot!!!

Nope. I checked and once or twice even a soft reset didn't fix the problem, so there weren't any programs running at the time. Thanks for the suggestion anyway, though; I'm pretty new at this XDA stuff, so you never know :D

Hi,

Man I know how frustating that is. I had a similar problem a few weeks ago where the touchpad only worked when I used my fingers, it didnt' respond to the stylus at all... I was *this* close to hard resetting or sending it in for repair, but a friend of mine suggested re-aligning the screen. Worked like a charm. Give it a try. I'm bogged down at work so I dont have time to look at where it was, but I think its in settings > screen somewhere.

Good luck!

Yesterday i cut a Screen Protector from an Ipaq hx 4700 to fit my Qtek S100, i cut it a little bigger so that it would fill the whole screen and be under the edges, what happened was that i couldn't tap anywhere, i did a Hard Reset thinking it was a bad configuration or something i did wrong, but the problem was the screen protector...i removed it and know it works just fine! I used Xbackup to restore my data and everything now is right!except i don't have a screen protector...

Yeah, I read about the screen protector issue before. That wouldn't explain why it is working fine most of the time in my case though. About your problem, the general consensus seems to be that the problem is the screen protector touching the sides. You could try again but cut it slightly smaller.

What's for this one?

I've tried running this on the device but it doesn't seem to do anything. What am I missing?

I've even removed the screen protector, but that didn't fix the problem either. Right now it is part of the screen (lower left) that is not responding. It's starting to get pretty annoying, but I'm reluctant to have T-mobile send the device off for repair. Since there's no fixed pattern to the problem I expect some repair guy is probably just going to hard-reset it anyway, try if it works for 5 seconds and send it back :(

Joost, let me know if you managed to resolve this... I have the same problem:

Will do, but it's not looking good. I can't seem to pin down a pattern, so it's hard to try and eliminate possible causes. I'm 99% certain it's a software problem; it comes and goes and I'm not even using a screen protector that might cause it. It seems to have something to do with calibration/alignment, because usually it's only part of the screen that becomes unresponsive (bottom left or bottom right mostly)...

As you can see (in the thread linked above), I managed to solve it -- it seems like there was a registry setting (in my case).

[Joost]

Did you ever manage to pin down what registry setting was responsible?

[frax]

no, I didn't spend any time/energy on it -- but you can follow my steps if you want to try that route.

But I am not sure it is the same in your case, for mine it was constant after the ROM upgrade, not something that would come and go...

[Joost]

I think I've got it!!! Bad touch screen response (and general slowing of the device) seems to be related to weak/no network reception. Probably Windows Mobile gives priority to reestablishing network connection over some other processes, amongst which is screen response. This would be ok if the network routine only tries at intervals, freeing up time for other stuff inbetween, but it seems it just keeps trying continuously.

The way to solve this is probably to lower the priority of the network connection routine. So far, so good... Does anyone know if this can be done, for instance by changing a registry setting? If so, which one and what value?

I had the exact same problem of non-responsive touchscreen once i installed the protector which came with the device. After reading thro this thread, i slightly lifted the protector from the bottom edges and VOILAA!! the screen works again.

Strange problem this !!! Thanks for all the help. :D
