[Q] peculiar touch screen problem - Defy Q&A, Help & Troubleshooting

hi,
My motorola defy[mb525 w\o motoblur] is six months old[so its under warranty].it has android 2.2.2;
The phone is "not rooted" or anyway tampered.
Now the problem i am facing are:
1:both the touch screen and soft keys becomes "touch insensitive" frequently
2:while watching videos in landscape mode, again the touch screen and soft keys becomes "touch insensitive" and sometimes the keyboard just appears and keys gets touch by itself.
I have to each time off\on the power switch to get the touch back
and there is no need of rebooting.
to solve the problem i have done the following
1:format the sd card
2:cleared the cache partition
3:did hard reset.
but the problem is still there.
Is this a software or hardware problem?
Is the problem due to any apps directly installed from sd card?
what should be done to solve it?
appreciate any help

The symptoms you describe sound quite familiar to me (although for me, the behaviour of the phone has been bad enough that I accept this as a lesser problem that I can just about ignore compared to some other aspects).
I believe it is a software problem, or if not then almost certainly not directly a touchscreen problem... What I mean is that I'm pretty sure the sensors of the screen are sending the appropriate signals in a timely fashion, but some aspect of the software is held up (by something that could be related to an underlying hardware problem elsewhere) causing the response of the system to be erratic.

Is there a solution to fix it?
or
Should i take it to motorola customer service\repair center???
and i thank you for your input

I'm afraid that I don't know a solution, and my experience of sending it to be repaired is that they are very likely to hold on to it for a few weeks and then send it back with a note that it has been tested and works fine...

Joypad and Softkeys not responding

I just flashed my girls 8525 and her joypad, softkeys, phone keys aren't responding anymore. They were responding at first, so I just figured a hard reset would do it. But it's still not working. The top message and IE button works though. Also, when I slide the phone open the softkeys there work. I can't even hard reset the phone.
Can you Reflash the phone? Maybe just a bad install.

Did that already...still not working
I think my phone is having the same problems as yours.
None of the physical buttons on the bottom of my phone are working. My scroll wheel works fine, as do the Power, Comm, and Camera buttons, and all on-screen "buttons" work, but it's like the bottom group of physical buttons on the phone are not responding. It's been somewhat intermittent, but now they're basically not working at all. I can't even hang up the phone with the End key, or activate the dialing pad with my Phone key.
I had done all of the WM6 Cingular upgrades from the Cingular website, and it seems my problems started shortly after that.
Just this morning, I ran the "Clear Storage" command, and now my system is running WM6, Build 18128.0.4.4, ROM version 3.62.502.3, ROM date 10/11/07
Have you tried flashing back to the ROM you had before that was working?
If it is not ROM related.......I would fear some hardware issue exist.
Can you go into the button settings under settings and reassign the button functions?
I'm downloading the ROM from HTC right now @
http://www.america.htc.com/support/8525/software-downloads.html
Will see if that fixes it, then I guess I will have to figure out where the previous ROM versions are archived, and download/install previous versions if this doesn't fix it.
Under the Button settings - the only 4 buttons that it allows you to reassign are all working fine. It's only the buttom cluster of buttons below the screen that are being "tempermental".
Oh - I'm fairly certain it's not hardware related because I can reset the phone, and push the Phone button, but then it quits working. It's like the buttons aren't being released / activated after the first time they're used.
Hopefully the ROM reinstall will fix it...
I'm having the same problem. All soft keys work for a sec after SR but go dead. I don't think it's rom based because I have HTC WM6 Rom, and all my troubles started after I put Pointui on my TYTN. I've Hard reset once already, might have to do it again. Anyone have any ideas why this is happening. I also get occasional white screen, again none of this happened before Pointui.
I get the occasional white screen, and I've never installed the Pointui that you mentioned.
Well, I just reinstalled the current HTC official ROM for the 8525, and without installing anything else, my buttons are still intermittent. I think it's the version of the ROM since the device is essentially "clean", correct?
The buttons seem to consistently function properly ONLY after I roll the scroll wheel. It's most definitely a software glitch.
edit to add: while randomly navigating around, I got the White screen.
Well, I've been on the phone with HTC, and AT&T's warranty department, and was basically told I could shove the phone up my a$$. What a POS operation.
Since my phone is out of warranty, they said if I wanted to do an "Out of warranty exchange", I could politely hand them $497, and they will joyfully ship me a replacement REFURBISHED phone. WTF!?!
In speaking with the warranty repair department, they said they would be HAPPY to take a look at it, and evaluate the problem, and call me with an estimated cost of repairs, of which the absolute minimum cost I would incur would be to the tune of about $129 - I was so appalled, I didn't write down the exact price. I told them I am 100% unwilling to give them money to fix a problem that I feel their software created, politely said goodbye and hung up the phone.
So, I'm essentially stuck with a phone that HTC / AT&T broke via their WM6 ROM update, and they're not willing to do anything (for free) to fix their mistakes.
My phone has suffered NO water damage, and no physical damage.
I did a ROM reinstall this morning, I did a hard reset (pushed the two dash buttons on the bottom cluster and held in the stylus reset button), and the only way I can make the cluster operate is to roll the wheel a few times, and then the buttons work (at least for one or two clicks, and then I have to roll the wheel again).
What a joke.
So, I guess I have to figure out how to revert to a previous WM5 ROM. Is this possible?
Everyone here is getting the same errors as me...the occasional white screen and so on. I've never tried scrolling the wheel to make the buttons recognize. I just hit the power button -> sleep mode -> power button and the buttons work again for a short time. LUCKILY phone is still in warranty and AT&T will ship me a new one <3 Buisness care...I'm thinking it's not software related because I installed schap's windows 6, on every last one of the hermes I've came across(About 10). Something might just be wrong with these hermes.
I have same problem with TYTN.... and what to do???
Okay - I bought a new phone over the weekend. As a last effort to fix the phone, I decided to google my problem, and I actually found the solution in the first link I clicked on. I feel pretty stupid, actually.
Slide your keyboard open, and look at the backside of the screen. The phillips screw at the bottom left of your screen - try loosening and/or tightening that screw. Mine was loose, so I had to tighten mine. My wife dropped my phone a week after I bought it (well over a year ago), and I guess the screw eventually worked itself loose.
My button pad now works like it should.
Guess I'll be taking my new phone back to the store and just keeping the 8525.
Did someone knof will that repair if i downgrade WM6 to WM5?
same thing is happening to my X01HT, wheel then it works for a few times and then it stops agian, wtf!?

I have had the same problem for quite a while now. I upgraded from the official WM5 that came with the TyTN to the official WM6. After a while the buttons on the front started to be intermittent. As well as the memory card "disappearing" and QWERTY keyword randomly dying (resulting in display fixed to landscape mode), both resulted in a hard reset to resolve. Anyway, to cut a long story short I contacted HTC who said they would repair the problems under warranty (as it was still in warranty) but due to my very misfortune the device suffered liquid ingress THE DAY BEFORE I SENT IT OFF!!! Thereby voiding the warranty (as notified by HTC after inspecting the device).
So, I would have to sort this out myself. I tried various unofficial ROMs, all of which work "for a while" (maybe a day or two) and then go back to being intermittent, and then not working completely. I have also used a WM6.1 ROM which seemed to work for a lot longer, but then stopped working just like the rest.
As of today I finally downgraded from WM6.1 as I was reluctant to do so before as I love some of the new features of WM6.1. But I took the plunge to see if it would resolve the button problem, as it was becoming a pain not having those buttons working. And the answer is........NO! After just a few minutes of me setting the device up the buttons ceased working.
I find the problem quite strange. I am a computer professional with an electronics background, and I am not convinced the problem is either software or hardware related (i.e. I am not convinced which is the problem). I have dismantled the phone on two occasions and all connections are connected perfectly. I have changed the ROM numerous times and tried different version of WM but all to no avail. One of HTC's solutions is to check whether a button is stuck, but all buttons are fine.
I have recently purchased Tomb Raider for Pocket PC, and within that game I have on numerous occasions "lost" the front buttons (on the occasions that the buttons were working). I happen to play about with other buttons, and after pressing the Comm Manager button all the front buttons returned to working order (but then they would stop working again shortly after). I tried this numerous times in Windows Mobile (6.1) when the buttons ceased working and it did not resolve the problem, however it still does in Tomb Raider.
After downgrading to WM5 I have noticed that with every power on and power off all the buttons and lights works correctly (in WM6.x if the buttons had ceased working then the lights would remain on even when in standby). So, it would appear in WM5 you can restore the buttons functionality by pressing the standby button twice (once to turn it off and once to turn it back on).
So, I am puzzled. Is it hardware or is it software? Any ideas? Is it a driver issue? Is it not informing a chip somewhere to power up the buttons? Is it a loose connection? Who knows? HTC certainly will not tell me (obvisouly because they want me to pay for them to repair it).
So, any ideas?

BTW the memory card problem and QWERTY keyboard problem were resolved by using an unofficial ROM.
Check that the "ok" button next ot the jog wheel is not stuck. Seems mine is, need to open the phone up and fix it.
I actually do not have problems with the D-pad but I'm getting problem with the Answer(green) and Hang Up(red) button...
Anyhow... anyone has a solution since then?
similar problems
hi i thought i would join this discussion as i have been having similar problems with my tmobile vario 2. i had it for a year with no problems and then the day i upgraded it to an orange tytn II the bottom buttons stopped working. i have taken the whole phone apart to check connections and everything seems fine and when i put it back together the buttons work fine for about a minute and then stop again. i have been tearing my hair out, i still have the original wm5 installed that came with the phone and before it stopped working it had been kept very well and not been knocked or dropped or anything. All the buttons on the top and side and the control pad and center button at the bottom work the only buttons that dont work are the 6 at the side of the control pad which pretty much renders the phone useless as a phone.
IF ANYONE SOLVES THIS PROBLEM OR HAS SIMILAR EXPERIENCES PLEASE CONTACT ME!!

Touch Screen Calibration Troubleshooting

The touch screen alignment on my Diamond occasionally gets misaligned and inadvertently aligns itself without warning. When I tap in one place, it registers in another. It is a really big nuisance especially in circumstances where I need to quickly input data into the PPC.
I was hoping that somebody had a solution for this?

have u tried realign???
I had that problem on my 2nd Diamond. Tried different version of ROMs but the problem still there, so I returned it and get a new one. My first one had a problem of self-restarting. Finally, now I'm happy my third Diamond
So ask if you can get a replacement, otherwise send it for repair.
Probably worth mentioning. I had a similar problem and it was driving me mad.
I was about to return the device for service, then I discovered it was a result of installing the GSen screen rotation program. I'd installed it to try it a few weeks ago and forgotten about it.
It turned out it that was switching the digitiser orientation without rotating the screen.
Uninstalled GSen and it's all fine now.
I'm hoping that uninstalling GSen will do the trick. Will give it a try tonight.
GSen was uninstalled and the problem still exists. Does anyone know if there is a firmware upgrade that handles this problem?
Have the same problem...
The touchscreen decalibrates itself.
2 minutes after calibrating it changes everything again. And just randomly.
Seems to be a hardware mistake, because even a hard reset didn't bring any help.
Anybody a solution?

Touch Response Problem

I have a Sprint Touch [Vogue]. It has served me very well up until recently.
One day, I was using my phone normally when the battery died. No big deal right?
Well, I charge my phone and reboot it. For some reason, Windows is EXTREMELY slow and unresponsive. I figure that something vital had been corrupted by the battery's death, and that it was nothing that a hard reset couldn't fix.
I performed a hard reset.
I let the utilities for the first boot run to customize the phone. Everything seemed pretty much normal. I configured my settings, re-added my contacts, etc. Then I turned the screen off [with the power button].
I turn it back on later to do something. I touch the screen. It immediately and accurately detects the touch's location, but it continues detecting a touch. For 20-30 seconds, after the input has stopped.
It was strange, so I soft reset the device. It booted, with the same problem. So I performed another hard reset. I did some configuration [the response acting normal at this point], and then turned the screen off. Turning it back on brought the same problem back.
This problem still exists on my phone, even after numerous hard resets and even ROM flashes.
A better description of the problem: When the device is first turned back on [meaning brought out of standby], its touch response is messed up. It will immediately and accurately detect any touch input, but it will continue to detect the input for up to 30 seconds AFTER it has been released, as if you were holding it the whole time.
WHY is this???? My phone is almost unusable because of this!!!! I can still place/ receive calls, using the navigation buttons and the red and green buttons. But the touch response is screwed!
Can someone please shed some light on this problem I'm having?
Phone specs: Windows Mobile 6.1, HTC / Sprint customized. Minimal third party software is currently installed.
[I've already determined that third party software is not the problem, because i haven't installed any!]
Possible solution
Hi,
today I experienced something similar to your description - no touch response when I tried to pickup a call. The strange thing is that last night everything was working and no settings were modified nor programs were added/removed. The screen suddenly 'died'. At the moment I am using it through a program MyMobiler which brings the mobile display to the PC and I can use the mouse to control the phone (it is like VNC for the phone screen, the phone is connected with ActiveSync).
This is temporary solution untill I finish my backups of files, programs, settings. I didnot performed hard reset yet, hope this will solve my problem
In the following link there is a 'magical' solution - to remove the screen protector:
http://www.htcwiki.com/thread/1112981/LCD+or+Touch+screen+not+working
P.S. I had removed the screen protector and voilá - the screen is now touch responsive. The root cause of the problem obviously is the dust between the screen and the protector which results in constant screen pressing - and as a result no accepting my finger presses.
I hope this will work for you and others with similar problem.
I had a similar experience with an old Vogue.....In my case, there was no battery death precursor, but it just started acting up. Not too long thereafter, I noticed the screen/digitizer was forming what looked like an air bubble between the digitizer and the LCD on one place of the screen. The screen was becoming defective. I eventually had to buy another Vogue from a friend who didn't have a clue of the 6900's potential, and didn't want his anymore, so I got it cheap.
Sounds like your screen/digitizer may be on it's last leg.

HTC dealers acknowledge touch screen problems

Don't know if this has been posted before, but it's something you should know:
http://www.unwiredview.com/2010/06/...ted-in-the-uk-htc-hd2-has-digitizer-problems/
http://www.htcphones.net/htc-hd2-problems-with-touchscreen/
I'm having hardware problems too and I guess I have to take my phone back and wait longer than 2 weeks for it to get back
Most issue with the screen have been covered already on XDA, before sending you phone back flash back to your latest stock ROM and try the new Touch dll screen fix posted the other day, this transformed my phone completely.
Thanks for pointing me to this hotfix, missed that. Just installed it, but to be honest, I think my device has a hardware problem, because the accuracy isn't the biggest problem, it's the complete unsensitive screen that is every now and then. Then when I press hard on the htc logo the sensitivity is back, so I guess it must be a hardware problem.
But I'll be testing it the next days.
Now this is weird; the fix didn't help. But I put off any lock screen (Windows standard, Windows classic and CHT lock screen) and now I don't have any problems with hanging screen.
So is this a hardware problem or isn't it? Maybe one of the techies here can explain why I'm having screen problems with the lock screen set to on only and tell me if it's hardware or software related (because when locked pushing the screen helps)? The question is: what exactly does the lock screen option do, technically?

S8 Touchscreen Issues

So my touchscreen is acting really weird and I can't pinpoint exactly what the problem with it is. Im planning on just sending in the phone for repairs, but wanted to post here as a sort of "last-ditch effort" to see if there is anything else I can do.
I've already done a factory reset of my phone (and it seemed to work a little bit better) only to start acting up again like 10 minutes later. Safe mode doesn't resolve the issue. I can't swipe to unlock my phone and pressing once either doesn't work or registers as a long press. Everything is telling me this is a hardware issue, but it started happening randomly with no screen damage and there seems to be a pattern to when the touches register and when they don't, so it might be a software problem albeit a very weird one.
This is what the touchscreen input should look like: https://i.imgur.com/qhTNgq9.gif[/url]
This is what the touchscreen input actually looks like: https://i.imgur.com/DFtMVSz.gif[/url]
Any help is appreciated. Ask me anything, ill try to get back as soon as possible.
Also, if this is the wrong place to post this, please direct me to the correct place.
I think really the only thing you might be able to do is reinstall the firmware, if that still doesn't fix the issue then it probably is some sort of hardware issue
Things you can consider
- After a Factory reset, try using your phone without installing any "other" Apps except the ones from Google. / or / using it in Safe Mode ?
- I am sure you might have already tried removing the tempered glass
- Did you try the *#0*# and test Touch ?
