Touch Screen Problem

Hi All,
I am using an IMATE Pocket PC 2003 since the last 6-8 months. Over the last few weeks I am facing a problem with the Touch Screen. ALl of a sudden the Touch Screen fails to respond although the buttons are still working.
Sometimes after several reboots, the Touch Screen responds sometimes it doesn't. Sometimes I just keep it IDLE for 2-3 Hours and the Touch Screen starts responding. There is no fixed time of the error also the error is random. Sometimes everything is normal for one week and there is no problem at all. Sometimes the problem persists continously.
I have Hard Resetted it atleast 4 times but the status still remains the same.
If anybody has experienced this, do share your thoughts.
Regards
Jinesh

I read somewhere that if you re-align your screen it may help.
Do your hardware buttons still work? You could try mapping tpenable.exe to a hardware button and select this when the screen locks up.

Touch screen problem
Jinesh,
did you ever manage to fix this?? This is exactly the problem I've been having on my MDA Compact (Magician) for ages: screen unresponsive, buttons still working. I started a thread on this topic as well and got some suggestions, but never managed to sort it out. I'm a bit wary to resort to flashing a new ROM or something like that since it seems to open up a whole new set of potential problems and will cost me my warranty with T-Mobile at the least (Not that they're much help, but still)...
Thanx,
Joost

Maybe the cover
The Qtek9090-screen is sometimes locked (e.g. when it's in a car holder which causes too much pressure on both sides of the display.) The same happens sometimes without any cause - pressing on both sides unlocks the screen.

Hi,
I am using an O2 Mini now and have sold off that Imate. But what I came to know that the touch screen problem was due to the irregularities in the network. The screen stops responding fast when network is weak and the device keeps on searching the network.
I have faced this problem once or twice in my O2 mini also.
Regards

Jinesh, I don't know if you checked out my thread on this, but indeed this is the conclusion I've reached: bad network causes the unresponsive screen. I think it might have something to do with the priority windows gives to the screen routine compared to (searching for) network. As of yet I have been unable to find a way to increase priority for the screen or lower it for network, though I browsed through the registry pretty extensively. Suggestions from anyone on this would be most welcome.

Touchscreen problem with WM6?

Hi, to all!
I have a problem with the touchscreen of my hermes alias O2 trion.
When starting from cold state the touchscreen works normal. After some time the screen reacts not allways and shortly after that it does not react at all. Reset does not change anything.
Is it a upgrading problem or is it a hardware problem?
Here the hole story:
I bought a used device with Win Mobile 5 on it. At the first try out it worked, but afer some time the screen did not react to my stylus at all. After a reset it worked again so i dit not pay much attention to this and upgraded to official Windows mobile 6 (which was downloaded from O2). Update worked fine.
Then i ran a rom update on the computer to change the start screen. The tion disconnected (update stopped at 0%). Little shock, but the trion still worked. The program and radio versions did not change.
First thought: this was no official update, so trion did not accept it. Was something installed or was everything blocked?
Could this make problems?
What do you think?
Thanks

Did you try to re-calibrate your screen? It could be a question of the screen loosing calibration so bad that when you press it, it works but you are not HITTING any buttons, because the calibration is off...
I have that problem with my Hermes, I need to recalibrate several times every day, especially after sliding out the keyboard (since the screen flips then) .
There's a very nifty short-cut to the calibration app: press the middle button on the D-pad while pressing the messaging button to go to the calibration screen, then press the middle D-pad button to launch the calibration (same as pressing "calibrate" with your stylus).
There seems to be a lot of Herms that have serious calibration issues. I'm personally so tired of it I am thinking of buying something else.
Good luck,
Laz

It's KNOWN hardware issue where the processor heats up and *somehow* transfer heat to the digitizer which make it unresponsive. I got a Hermes just like that laying around. Can't fix it.

Thanks!
Today the touchscreen worked good. Even playing spider solitair was possible. Then i pluged it into power supply and the device got slightly warm. The touchscreen did not work any more.
Could be a heating problem of the prozessor like Mikro_ Tech described. Thanks by the way
How can i be sure it is this problem and not something else?
@LazPL: That was one of my first thoughts as well and i did.
When the Touchscreen works, it works just fine and accurate. Then it behaves strange (sometimes not corresponding to touches, programms close all of a sudden) and shortly after that it doesn not work at all.
@the_passenger: The Hermes Version is HT 626... Anything special to this, because the link just lists screen allignment issues for this modell?
What do you think of the solution from the link LazPL posted?

6.5 official upgrade issue? (phone turns off when openning the keyboard)

hello
i've upgraded my tp2 to the official 6.5 yesterday, and i found that when i open the keyboard the phone turns off!!
anyone had similar problem?

No,I have not such kind off problem.

Only thing you can do now is to flash again. Looks like something went wrong by the instalation... Will work for sure.

may i suggest re-flashing the rom or doing a hard reset? This is the first I have heard of such a problem, my one runs just fine.

I have this same problem. I believe that it is a problem with a slider connection being loose or something. I discovered that if I slowly slide my Touch pro 2 open, the phone would not power off or restart.

i had the same problem from time to time with my htc herald. On the TP2 i didn't watch this behaviour. i think it has something to do with a loose connector of the keyboard inside or something else

i did a hard rest but still the same & the problem happens every single time i open the keyboard...
re-flashing at the moment, I'll report back

everything seems fine after flashing another rom
thx all

screen is not responding, help needed please.

my tp2 touch screen is not responding suddenly!!! the problem started only after i answered some call through the screen slider, however, the touch screen is not responding to my fingers ever since !!!!
now i'm operating the phone only through the buttons !! but as if it is not touch screen!!
anyone have a clue about what the problem can be?? please help me. my device runs wm 6.5 and this is the first time to have this problem, i did soft reset many times but no imrovment!!
I had SOD this early morning and it was my first, do you guys think there is a relation between these events???

I have the same problem.
Just happened this morning.
I was able to use my mobiler to access the screen.
Tried several hard resets. No luck.
Tried re-installing energy Rom (4.1)
Then tried the new Energy Rom (4.11) still no luck.
But then I got the big idea to go back to the stock ROM. Now I cannot use the on screen prompts to access "my mobiler"
Anybody have any suggestions or is it back to AT&T for a new phone?

so whe you back to the stock rom, did u get ur screen working again??

No. no workey
Now that stock rom is on. I keep going back to the "Sim Card Changed" screen. I can not tap "cancel" or "Next". I can use the hard buttons so I am able to get to the phone and then use keyboard to dial.
Still no touch screen. And no work around with keyboard to get to screen. need a "Tab" button. then might be okay.
this sucks.

Just a quick bump before I go to AT&t in the morning.

Try running task 29 and then flash back to a stock.
And have you tried taking your sim card out of you're phone? Maybe that will avoid the message.

i'm buying a black berry

Does your screen look as if an oily residue is under the touch screen part?
My screen stopped responding a few weeks after the appearance of the 'oil' and Vodafone swapped it with no problems. It seems like a fairly common problem

yes, I've got that oily spot and somehow i managed to relief the problem only for minutes when i raised the digitizer carefuly which got me the screen working for few minutes untill it went unresponsive again after while. I'm looking forward to do alcohol swab to this oily spot and will see weather this will solve the problem..

Samsung Galaxy Grand I9082 Safe Mode problem after changing the touch screen.

Guys i just got problem with my Mobile i have changed the touch screen few times from repairing shop but every time it comes with a new proble. i just bought a new touch screen from the hardware shop and replaced it by myself. now touch is working fine but there is another problem it just starts in safe mod. i have restarted it many times but the problem remains the same. i checked it with the old touch panel and mobile starts in normal mod with that. can you guys help me out with this? I will be thankful to you guys. Sorry for my English.

I think you have bought an incompatible screen. try connecting older ones or buy a new one

While rebooting the phone keep tapping the left most button (what ever that is called). There is a Youtube video too.
I too faced a similar issue after replacing the screen and happens when you fiddle with the buttons when the phone is booting up.
