Less responsive touch screen at random times

It seems the touchscreen of my Desire gets less responsive at random times. Anyone else who has this problem as well?
The touchscreen of the Desire is very sensitive in most cases. But it sometimes (randomly) becomes less responsive. I have to give more pressure for the screen to register the touch. This is especially annoying when typing an e-mail or text message.
But for example: when sliding between the screens at the homescreen (Sense), you have to barely touch the screen to slide. When my 'problem' appears, I can actually feel and slide on the screen but nothing happens. When applying more force it does work, but is not as comfortable...
When I reboot the problem seems to be gone for a while, but at some point it becomes less responsive again.
Obviously I have tried uninstalling apps and widgets and see what happens then. But the problem remains. Hard reset/factory reset appears to be working at first, but again after some time the screen becomes less responsive again. This can be after a few minutes or after a few hours. The only way to 'solve' this is to reboot the phone again.
So! Is there anyone who is experiencing the same problems? Because of the factory reset (and obviously not installing any apps after that reset) it seems to me this is some sort of hardware problem.
Any takes on the issue?

I only get such a problem when my hands are sweaty or sticky and when the screen is smudgy. I'm a cleanliness freak though so I naturally keep my hands and the screen very clean avoiding this problem. Otherwise everything is pretty darn consistent on my side... except for one oddity.
I struggled with this phone for months and then gave up trying to type or even just use the touchscreen while it's laying flat on any surface. Most of the touches just never registered, honestly. Even when applying a lot of pressure. Until last week, quite unexpectedly, the touches started registering perfectly. Just as good as when holding it vertical. I was quite amazed and baffled at how something just changed automatically to improve it significantly. The only other observational change in sync was that some apps that kept changing the phones layout based on the way I'm holding it even when I had disabled this feature (like the Tapatalk XDA app) have started working correctly as set now. Just all of a sudden.
I haven't made any setting or config change. I did root a while back but unrooted very soon after by flashing the stock T-Mobile ROM and things were still as bad as the beginning. That's something like 2 months back.

Ok, weird!
Since I am able to reproduce this with and without installed software (hard reset, no sim, no sd, no nothing) I can only assume it's some sort of hardware problem.
So off to repair department it goes! Thought I'd post it here and perhaps someone would have a solution saying:"Oh! That's this or that". You never know

What I found is sometimes it's unresponsive but it's *puts on black roll neck and jeans* the way that I'm holding it.
I think if you squeeze the phone too much it registers a touch on the side of the screen. Also so times when I'm using it one handed the ball of the bottom of my thumb touches the screen and this is registering, making the rest of the screen unresponsive.
I'd consider this to be the problem first (as annoying as it is). I used to have the 2nd problem on the iPhone, but not the first. It's a bit upsetting but I got over it.

Are you using a screen protector at all?
Since you have the same problem after performing a hard reset, maybe you should consider taking it back to the vendor for a warranty repair or replacement as it could be a faulty digitizer.

hardware problem?

hi, had my desire z about a year now, since ive had it, quite rarely ive had a problem of it seeming to have a mind of its own, for example, icons may be selected, or the home screen will slide accross by itself etc. ive always put this down to a trackpad problem.
the other day (after having a miui rom installed for about 2-3 weeks, which was fine untill now), it started acting up strangely, the above problem started happening, but more severe, also the touch screen and softkey buttons would stop working for periods of time (or stop completely untill reset), but screen rotation etc would still be working, which shows that the O/S has not frose and is still working behind the scenes (making me think its a hardware problem).
now, i think ive worked out that this seems to be triggered (mostly) when i open the keyboard. (as also, when the touchscreen stops working etc, sometimes, sliding the keyboard open and close several times, will sometimes seem to unfreeze the touchscreen etc, and will be back to normal, for a while). ive tried doing full wipe and reflashing etc, but i still have the same problems mainly when using the slide out keyboard, which again, makes me think its hardware (possibly keyboard ribbon cable?)
i really dont want to send it off as that means getting it all back to stock etc, and last time i needed the screen replaced, took 6 weeks to get it back!
if anyone could pinpoint the likely source of the problem, id rather replace the part myself..
would anyone have any ideas, as they would be very much appriciated... Thanks...

anyone at all?

I got 2 Zs meanwhile but dont have any problem with the keyboard.
But sometimes when its charging i got the same issues like you - no touch is working and the screens are sliding nearly automatically.
I think this has nothing to do with the keyboard...
Hope this had helped you a bit

thanks for the reply, unfortunately im still no closer to finding source of the problem, its intermittant, happened lots yesterday, not so much today, maybe the digitiser? its like there is another invisible finger touching the screen..

This would happen when i was on stock froyo, like it would cause the home screen to hang, but if i was ion an app it worked fine. I would use it to refresh of sorts when my phone was hung up or i need to reload my apps from sd lol. Sounds weird I know, but even with stock froyo i had problems with my keyboard but with the prerooted GB its as smooth as butter...

still going on, and getting more frequent, i dont think it is to do with the keyboard anymore. im now guessing it is the digitizer, its like someone is pressing an invisible finger on the screen, roughly in the center. it comes and goes, it happens for about 3 days, then goes away for a couple of days etc.
also there is very little info anywhere on the net that can help, including replaceing the digitizer itself
anyone ever replaced one on a disire z/g2?

[Q] Touchscreen Issues

So for the entire year and a half I have had my T-mobile G2 (aka HTC Desire Z) my touch screen has had issues.
It seems to happen mostly when I am doing something memory intensive, but not always.
My screen either goes completely unresponsive to touches or acts like only 1 touch is performing “pinch to zoom”.
To remediate this issue I have to hit my top power button to turn the screen off and then back on, but this is just a temporary fix.
It does seem to last a little bit longer before starting this behavior if I do a complete reboot.
My phone is still usable but this is an ultra-annoying issue that I believe should be able to be fixed. I have used task killers and messed with the performance options in cyanogenmod to no avail.
This has happened on the stock ROM and every other rom I have ever run. I am currently on Andromadus Alpha (http://forum.xda-developers.com/showthread.php?t=1349864).
Thanks for any help in advance.

I have the same problem since its new.
It does it when the screen is dirty too.
Makes a huge difference when I'm using my old moto milestone, the screen is more responsive.

[Q] Screen lost sensitivity until lock/unlock phone

Hi All,
Just got my One X and I'm quite impressed. Sadly, I discovered an issue with the phone even after having done factory reset.
While using the phone with any application, it will randomly loses the sensitivity. What I mean is that no matter what I do on the screen, nothing will happen - I can't drag, I can't click, the buttons don't work etc. However, if I lock the phone and then unlock it, the screen will work again, the sensitivity is back.
This problem occurs very often but at different point in time. Sometimes it would happen right after I start using an application. Sometimes it doesn't happen until I have been using an application for a good while (5mins+).
I plan to return the phone for repair/replacement. However, before doing so, I would like to check if anyone has experienced similar problems previously and if it is indeed a hardware issue. It would be great if I can have some insights, so that I can describe to the customer service assistant who is (more often than not) clueless about what I'm talking about. Also, since the problem doesn't seem to occur with a pattern, I am wondering if/how the engineer will be able to detect the issue and provide a fix (or even better to offer a replacement).
Thanks guys

this happens to me too not as often as you describe and not as severe but even yesterday i was in twitter suddenly touchscreen loses sensibility and for example scrolling takes me 5 swipes to move a tweet off the screen but usually restarting the App fixes it

Did you use it while charging?
sometime the bad power supply will make your phone freeze

I think it's a Tegra 3 issue, because my Asus Transformer Pad 300 does this sometimes, aswell.

Touchscreen issues VZW M8

My wife and I both have the VZW M8, hers is stock and mine is stock rooted. A lately we've both been having issues with the touchscreen getting crazy.
While texting, the gesture typing trail will show up on screen when we aren't using it. Easily fixed by turning that off. However both phones are having issues with phantom touches or complete unresponsiveness. Turning the screen off and then on after a few fixes it briefly, rebooting and letting it sit off for a bit works as well. Just trying to type this up I've had to continuous issues.
Can't do my daily crossword puzzles because it jumps around the board constantly and that's bull****. Anyone else having problems or ideas as to how to fix this?
