Hi Guys i hope somebody who knows about capacitive touch screens can help me! I have taken my HD2 apart to fix a smashed camera lense. On removing the back cover i used a small screwdriver to prise off the back case and unclip it all round. It came off with no problem, i fixed the camera and put it back together. When i turned the device back on the touch screen isn't responding to my finger on any screen. Like i turned the touch screen off! The hard buttons still wok but nothing from the screen. Nothing looks damaged (I.e the glass isn't smashed). I seem to think i might have damaged something when prising the cover off with the screwdriver. Please, any suggestions would be really helpful!!!
Can anybody out there help with this? I am currently without a phone :-(
I have exactly the same problem, but it happened from nowhere. I didnot unscrew anything. Please Help
Check the flex cable.. this part are very delicate.

same problem
ive got the same problem, mine just stopped working, i performed a soft and hard reset, removed the battery still nothing. it worked for a moment but once locked it stopped working again, only the hard buttons.
same problem but it works on and off. basically the screen will respond until the phone is put into hibernate. the after that id have to push the phone button and end button back and forth until it responds
Same Issue independant of ROM
Same issue here.
Funny thing is it started a week or two ago randomly out of the blue.
Same scenario:
lock the phone can't get touchscreen to respond for unlock
Judging by these posts everyone started seeing this about the same time, maybe it's a software issue or background app .
Help!
I have same problem. It can work for a couple of hours or in 1-2 days then just stop responding, almost every time when in hibernate. Lets just hope it's not hardware failure.
This started happening to me this morning. Out of 50 tries, managed to unlock the phone three times only. This happened out of the blue, right after i removed my phone from the charger.
Have soft reset, hard reset, reflashed ROM, but the issue still remains.
I really really hope this is not a hardware issue.
Does anyone out there know how to solve this? My phone is virtually unusable right now...
Same problem here, I've been testing for about 2,5 months now and today I've sent mine back to HTC . I think it's a hardware problem, tried everything from hard resetting to reflashing. When I press the HTC logo and keep it pressed the screen does respond again. Conclusion: hardware problem.

You're probably right.
I've also tried everything. But kind of strange that if I lock when not on home tab it seems to work. And the screen, almost always, reacts as it should as long as I just dont' lock it.
I just started to get this issue. touch screen works fine until it hibernates. reflashed, still happens. found this in my search:
htcphones.net/htc-hd2-problems-with-touchscreen/
just got off the phone with tmo. they are sending me a new one.
Yeah, it happened to me as well. I opened a new thread like a month ago explaining the problem: http://forum.xda-developers.com/showthread.php?t=710282&styleid=15
and I contributed in another one concerning the same issue here: http://forum.xda-developers.com/showthread.php?t=708530
Summing all up, it ain't caused by a software or a ROM of some kind (at least in my case) because soft and hard resets didn't solve it nor did the flash of a stock ROM. The most probable cause is a digitizer (touchscreen) defect that appears randomly and totally out of the blue. The only thing to do in my opinion is to send the phone in for repair, which I did. It came back with a check mark on "calibrated screen" checkbox. As of now phone's working fine and I hope they solved it even though I read of other people who have had their leo's screens completely replaced..
A curious side note: htc care reset to zero my phone's call duration timers..
I'm not sure if it's the screen. In my case I think it's the connector from the screen to the motherboard, because pressing the housing seems to help.
But let's see if HTC is able to repair it, I hope they are, because the problem is so random they might not even see it
After losing functionality on my touch screen for a week, finally decided to send it in. Took the trouble to revert my HSPL to original and Stock Rom.
Repair should take about a week. Now I'm stuck with an ancient Nokia 6230i for this week. I feel so lost without my ppc. Have had one for as long as I can remember.
Hopefully the phone comes back okay...
I've had so much problem with the screen not responding so I did all backup then reflashed, hard reset to put the device back to stock. Did this during the weekend, I even fired up my old iphone 3g to have as backup phone.
All set today to go to the store and have it repared under warranty.
But since Sunday evening it works perfect. I've been testing it a lot and the screen has not stop responding even once.
This might be just temporarily but does anyone else experienced something like this?
Mine sometimes worked well for hours... days... but eventually the problem came back.
Mine died on me when I was actually out of the country (stuck in Vietnam without a phone). It would work for 5 minutes, then stop for hours. I would have to switch my phone on and off for a couple hundred times before it worked for another 5 minutes...
Got so tired of it that i sent back my HD2 for warranty repair. Expect it to be back tomorrow (or Friday at the latest). Hope there's no further problems with it.
I hate to say it, but the HD2 is known for its highly defective touchscreen. Even when it's working, a lot of people experience strange and bothering events, such as the touchscreen "touching" itself, a very high/very low screen sensitivity all of a sudden, the tilting of the screen to one of the four corners of the device and so on and so forth.
With a device so expensive one would expect it to work flawlessly. Seems to me that HTC doesn't think the way we do...
I have been using Ultimate Droid 3.2.5 for a couple of months now and a few days ago i pick up my phone to make a call and the screen doesn't respond when I touch the screen. Only the bottom buttons and volume buttons work. At first, if i I play with the buttons at the bottom i can usually get the touch screen to repond. I tried to wipe data/dactory reset and reinstall rom but now I cant even get it to work like before. Only thing I can do now is answer calls and call back the last person that called me. Has anyone else had this problem?PLEASE HELP!!! Thanks!
Did you eventually find out what cause this issues?
I think my phone is behaving similar, I'm using different Android ROMS for quite a while now, and suddenly without any apparent reason the touchscreen isn't responding very often after waking up the screen. It won't happen if the screen is on and the touch screen is working, only after a wakeup..
Sometimes it's just impossible to get it working again, and I'm forced to wait a while until it decides to respond again. It kinda feels like the phone is forgetting to wake or initialize the touchscreen properly.
ROM and Kernel changes didn't solve this so far.
I think the issues originally started with Typhoons CM7 NIGHTLY 3.7.1 / tytung 12.4v3 for me.
Actually I never found out what the problem was. I just flashed it back to stock and had T-Mobile send me another one. That was in May and actually a few days ago it happened to my phone again. So this time they sent me an HD7. It really sicks that they dont have that phone anymore. Cant do sh*t with this HD7!
Same here the Power Button is the problem, you just have to train yourself not to use it. I use Button Savior and Button Remapper. On my second HD2, luckily T-Mobile sent me a HD2, but that was in like March, right before my one year was up.
Make sure you keep this one working cuz there will be no more HD2! I may find one on Craigslist or something. This HD7 and Windows 7.5 really sucks monkey nuts!!!

Yea I played around with WP7 on the HD2 when it first became avaliable and wasn't really worth the time and trouble it took to get it on there. One month later I went back to NAND and haven't looked back.
Same here! Registering Zune was a problem at first.
Thanks for your quick response! Yeah, seems to be a problem with the end button / flex connector of digitizer
I found another helpful thread about this issue: The Infamous Unresponsive Digitizier Screen Possibly Solved!
Obviously you need to replace the digitizer to fix this problem.
I'm sticking to the solution of not touching the button at all, there are apps to turn off the screen and shutdown the phone. At least waking with any other buttons works most of the time for now, but it's not really a long-term solution.
Wish I would have saw that thread b4 i sent my phone back!!!
Hi there,
Just wanted to run this issue past you guys with my htc tattoo. Basically, sometimes my touch screen just doesn't respond to touch input at all, the phone still woks using the buttons but that's all. its random as to when it does it and it can go a week or so working fine.
I've tried re calibrating it (when its working) but the problem still comes back. I didn wonder if the screen was faulty, but its not all the time?
Its still on the original (orange)rom, ive never put an unofficial rom on it.
Could it be a loose connection inside the phone,ive no other screen issues.
I have reset the phone back to factory defaults before but this doesn't stop the issue from coming back
Any help/advice would be great
Regards, Chris
The problem began randomly while using CM7 Barebone. Upon boot, the phone works as usual. However, it would stop responding to my touch when I would try to slide the unlock screen. I would have to turn the screen on and off a couple of times and finally it would respond again.
I assumed it was a ROM issue, so I switched over to Paranoid Android, however the problem is happening on this ROM as well. Initially, I assumed it was a hardware issue, but the phone works perfectly fine right after I boot it back up.
Does anyone have some idea as to what could possibly be happening? I'm worried that this will just get worse and I'll end up having to purchase a new phone.
Search for unresponsive screen, your issue is likely to do with the digitizer. When you Held down the power button to reboot the phone this temporarily fixed it (it's a known temporary fix). Install some sort of lock screen widget so that you don't have to use the end call button too much, and unlock using any of the other hardware buttons.
Folks,
I recently bought i9505 international version (software version 4.2.2) and it worked fine for just over 2 weeks. Couple of days ago the two capacitive (back & menu) keys began behaving strangely. They randomly stop detecting the touch and therefore stop working. Sometimes both don't work, sometimes just one of the two while at other times both work normally. It's really frustrating to use the phone as back key is not working 80% of the time. Menu key seems to not work around 40% of the time.
I tried factory resets twice with no positive result.
Has anyone else had this issue? Does anyone know why and how to fix?
Thanks in advance for all replies.
Cheers
same here ...
but i can solve my problem,
while screen off, touch and hold the touchkey while you turn on the screen and unlock.
so i think its not really a HW issue,
any one can give me permanent solution ?
