Today I noticed, that my touch screen behaves very stangly. I used Multitouch visualizer and it showd, that sometimes two close points are detected instead of one. Very similar to yhis video: http://www.youtube.com/watch?v=LL_kubZ4ENc but points are in different places.
I made a full reset and formatted /system, but problem still here. Is this software or hardware bug? Does anyone have this problem?
EDIT: I found that whole line form top to bottom doen't responce. I think my warranty is just out ((
EDIT2: Magically this big disappears. The reason is unknown.

Hi,
I've just received my TyTN today and I'm not very satisfied concerning the touch screen.
I don't know what is happening but the touch screen does NOT respond properly. I've tried to clean it a bit, but the result remains the same.
When I want to use the screen keyboard, it's horrible. I point the letter A and the screen understands that I'm touching the letter under or the letter just near the "A". It's pretty impossible to write a text properly and very hard to open programs or browse with the touch screen.
Of course I've tried to align the screen. It's working without any problem then.
But after some times, opening apps, closing others (using normally the pda inf act), the problem comes back... the TyTN does't really understand where I'm touching the screen.
Then I make a screen alignement, and it's working back... It's just amazing
I don't think it's a hardware problem because the alignement is working after an align screen.
Maybe it's a known error ? Has somebody the same problem ??
Is there a rom update to fix that ? Or is it a problem of my own HTC ?
Thanks !
Can you help me please ?.
Hi,
I don't have this issue with mine...
Check the "TnTN/v1604 problem" topic maybe
I had the same thing, once, with my variO. Probably I pushed too hard onto the screen while cleaning.
Actually, this is a known problem with some of the first shipment devices. Look at the other TyTn topics i this forum.
A friend brought me a good one today. He has an AT&T Touch Pro with a touch screen issue.
He brought me the phone months ago and I flashed the ROM. All was good. He then deleted a bunch of files one night accidentally and hard booted the phone in an attempt to get the files back. Upon hard reboot the phone hung at the calibration screen and he could not get past that. To describe, the screen calibration works on 3 of the 4 corners, if you hold the press the stylus to the screen quite firmly, but the top right corner will not calibrate however long I told the stylus to the screen.
He brought it to me today and I figured that a fresh ROM would resolve the issue. So I loaded a new ROM and the phone hung again at screen calibration. So I did some research and found a "welcome.not" work around to get us past the screen calibration issue. This was successful and I was able to get us to the home screen.
The issue is that the screen is very unresponsive and I have flashed the device so it's not a ROM flash issue. Is there a driver he might have accidentally deleted that is not reinstalled on a ROM flash? I know I am probably grasping at straws here but I thought this community might have some insight to what the issue is.
I have also considered the idea that I may need to replace the digitizer for this phone if that is the issue and am prepared to do so but thought I would throw this question out to the community for any tips/tricks or ideas you may have before cracking the case on this thing.
Thanks for your help in advance.

Oh and I forgot to mention that sometimes the screen works if you tap it continuously but most times, there is no response.

Hey Mike,same issue over here.I couldn't find any solutions so far.By the way,what's that "welcome.not" thing?
Well,after some google search i ended up with this.http://bittangents.com/2008/10/28/removing-welcome-message-doctors-appointment-on-pocket-pc-2003/
I suppose that you were meaning that...right?

The calibration of the screen
IWPantel - Thanks for referring to my blog
To stop the welcome message, you need to put the Welcome.NOT in the root of a sd card or of the device. I don't believe this is your issue, however.
There are typically three reasons why the screen will become unresponsive.
#1 You have a bad touchscreen. Assuming that the screen was working perfectly, I highly doubt this is your issue.
#2 You are calibrating the screen with the stylus straight up. Believe it or not, the touch point changes if you are straight up and down, or if you have the stylus as if you are writing. The angle will affect the touch point.
#3 You have a conflicting .reg file in the Application or Platform directory of the handheld. The calibration settings are stored in the device's registry and they need to be updated. If you did a persistant registry tweak (where it exports the registry into NV ram, the calibration settings will overwrite the calibration settings you create on system startup.
Feel free to contact me with any questions.

Brent, I had the same problem here! My Fuze simply stopped responding to my touchs....
#1 Taking this as true
#2 I tried a hard reset, but nothing happens. I can not touch the screen to calibrate
#3 I just can not understand what you proposed.
Please, help me!
I don`t know why, but my cell just back to normal!
Now it's everything working!
@brentblawat - How come you are a Junior Member when your answer is so hardcore.
Anyhows, I have the same problem with my phone, I have tried all the software tricks I could think of. I guess your point 3 asks us to manually enter the calibration data in registry. Have tried it doesnt work.
I cant replace the hardware as I have Tmobile MDA and I dont get the spare parts for this here. the digitizer is different from the one in Touch pro.
Hello there,
I have problem with my screen alignment.. ASUS P535. It repeats again and again.. I updated my ROM and nothing happend. Then I've changed digitizer on my LCD. It worked, but for 1 time. When fresh copy of ROM started. Screen alignment was correct. When I've got loaded my WM device restarted and asked to align screen. And nothing happend. And it again repeats.. What should I do now? Maybe is there a way to upload screen align file direct to my ASUS P535? Or any other suggestions..
This happened to my bother-in-law on his omnia. he had it replaced 3 times. 3 devices, 3 bad screens after a few weeks each. The alignment was way off, and if he hard reset.. he got stuck on the alignment screen and could not go past it.
Tapping all 4 corners and then the center should all line up perfect or it will repeat until it's right. If the screen is messed up.. (Not registering the taps accurately) this would cause your problem.
I know you replaced your digitizer, but I think you have bad hardware.
did you notice the screen was not accurate before this happened?
Yes. It was not accurate. Half screen from top was accurate, but other half not.. I had to tap screen ~1cm lower to hit correct 'button'.
Ok.. If hardware is broken. So then which part? Or just I'll take my device to pro to fix it.. If it will be possible..
I also used Remote Screen Alignment software. It solved align problem, WM is working, but everywhere I tap, it taps bottom right corner.
I got nexus s (i9020T) recently and found the touch screen unresponsive sometimes. I've already tried several launchers(adw, lancherpro, go launcher ex), and it seems not launcher's problem. I've also tried to flash different ROMs, including CM-7rc2 and stock 2.3.3, and the problem remains.
Later I tried to bind Multi-touch Visualizer 2 to long pressing home button, and found the when screen is unresponsive, it can still detect press near edges very well, but not the center. While I press at the edge and drap across the center, it keeps tracking my finger correctly. In addition, Locking and unlocking the screen can solve the problem temporally.
I'm confused by the strange behavior, anyone experienced similar issue?
more info from test,
I connect my phone with adb, and tried to "cat /dev/input/event0"
The behavior confirms what I see in Multitouch Visualizor 2: the when the center of screen is unresponsive, nothing can be read from the device node.
I read the mxt224 touch screen controller doc, and it seems the chip features self-calibration, and thus I believe the "lock & unlock" will trigger the chip to tune it self in some way. I don't know kernel very well, so I cannot find the source code Any help please?
FYI. we are not alone.

I got this problem too whenever my phone is in my pocket facing inward.
I have tried to open the calculator to see which part of the screen having problem. Mine is usually the "8" and "5" location unresponsive if my phone stayed in my pocket facing inwards for a certain period of time.
The problem will goes off after couple of mins when i can feel that the phone is cooler than my body temp.
I knew this happens to the Dell Streak as well.
So, have a bit of a situation and not sure what to do.
My touch screen is working, but only to a point. Only the top status bar and bottom about the same size does not respond at all across.
I've attached a picture as an example of which part of the screen highlighted in red does not respond at all to touch. Everything else not highlighted in red works fine.
Have used my mouse to access boot recovery mode, reinstalled hal 9k mod rom, wiped cache / data and it made no difference.
Even updated my MCU to the latest version available for HA unit, and attempted to re-calibrate the screen via extra settings.
Not sure if original factory rom will fix this, but would like some opinions.
maybe take it apart and check the screen connector is in correctly, sounds like a hardware not software problem.

Hi,
I have similar problem on my px5 seicane unit. the bottom part touch screen won't response or acting without touch after wake up from sleep. restart the unit would result the issue.
wondering if you have resolved the problem? If so is that hardware issue?
just realized the touch screen issue I have on my headunit is probably hardware issue.
in the past I have to re-start the unit, that actually fixed the problem, don't know why. but now I just push the touch screen with my palm firmly. that would fix the problem as well, and last much longer (3-5 days). haven't get chance during the weekday to open up the unit. but at least it worked. and probably proofed this is hardware issue.
I have a Joying unit with a PX5 board. I also have the same issue as the original poster.
I would also say this is a hardware issue. Mine was fine with both the original PX3 and PX5 for a while. Now it is increasingly getting worse. Resets do nothing to solve the problem.
I live in a hot environment. Maybe that is a contributing factor?
