Hi,
I have a touch screen problem with seems like if the screen "feels" a non-existing touch so that when I actually touch it with my finger it activates pinch-zoom mode.
The problem appeared after I left a phone on a shelf switched off for about 1.5 month waiting for a new battery to arrive. When I switched it on with a new battery the mess started.
Tried the old battery, factory reset. The problem persists, sometimes right after boot, sometimes 1-2 min after boot.
From searching the forum I understand the most common problem with Hero screen it bottom freeze, but that's not my case and I couldn't find problems similar to mine.
Thanks for help in advance.

I have a T-Mobile Pocket Phone Edition,
It's had a rough life but as kept going for over 3 years now.
For the last year I would have to realign the screen 2 or 3
times a week but over the last few months it keeps getting worse.
Sometimes the screen won't respond to anything anywhere,
then after I tap it a few times boom works fine.
Sometimes I'll tap on the “Ok” and the “Start menu” will activate.
Sometimes drawing a line up the center of the screen will end up
shooting all over the screen.
And sometime it will work perfectly!
I thought the problems were to erratic to be hardware so
I hard set after awhile it started again,
So I hard set and installed a different ROM after a coupe hours
the problem was back.
Also sometimes the align program will get stuck in a
loop that doesn't end.
I've searched but can't find an answer? Anyone have an idea?
I've already taken it a part once but couldn't see how to get
any further after I toke the back panel off? Please help!
WOW nobody? So no one was heard of this problem before?
Can anyone direct me to directions on taking apart the Wallaby?
Thanks <><
It's a problem with touch screen. You should check (and fix) it.
Maybe it is necessary to press well screen to the motherboard. (Sorry my english).
Ok, Can you tell me where that connection is?
Thanks
Toke everything apart, found the connection, cleaned everything (w/ screen wipe)
put it all back together. Still have the touch problem and now the backlight won't work!
I've found if I press the unit in my hand the touch panel works right,
I don't think it's a lose connection to the main board so I think it must be
one on the main board.
If anybody thinks they want it for parts let me know! :?

hm... try hard-reseting the phone. but back up your data first using some backup software like sprite backup
Tried that as well no luck any other suggestion guys
Sent from my HTC HD2 using XDA App
I had the exact same problem, and I had to hard reset everytime, but as soon as I would press the end key it would be unresponsive. What I learned is that right after you hard reset you should only try waking pressing other keys than the end key and let it go to sleep by itself. Also did you use any EVO android builds, or Android at all, not sure if it's relevant, but that's where it all went wrong for me with the EVO build. I do find it quite odd that quite a few people are experiencing the same thing with the touchscreen and it also seems that there really isn't a solution to this. I had to send it in for a repair, and it got fixed pretty quick. Perhaps this needs to be investigated more.
i have same problem with my htc hd2
it is so annoying. i will send to repair service too..
hey i have the same problem too ! did you installed the new c0okies home tab ? because i did and after that it start it messing up.. well i did a thread yesterday about this.. the only responses i got was to send it back to repair. I just did not turn off the screen for nothing today during the whole school day it almost finisihed the whole day, it last it me about 6 hours without turning off the screen, otherwise the touchscreen becomes unresponsive.
Temporary fix/test
I just fixed it temporarily, i fixed it by taking off the battery cover and pressing down on the htc logo (below lcd) and pressure on both the front and back of the phone where the htc logo is.
if you do this and it fixes it, you most likely have a dodgy lcd/digitiser flex ribbon cable.
My brand new unbranded Mozart has terrible lock screen lag issues. Phone was perfect to start with then after the usual updates and 2 days later, is proving very hard to release the lock screen. I need to wait at least 5s until the phone starts responding. I have noticed it does the same when on the phone (i.e when the screen senses proximity and goes blank). anyone no of this phone having wake up problems etc.?
Quick update - if I swipe up the left hand side of the screen the lag seems to vanish! (for that unlock only).
i.e swipe with index finger from the bottom left above the back arrow upwards and the Mozart seems to respond better!
Wierd but true. Just wondered up this works for anyone else experiencing the same problem.
The lock screen hasn't been responsive on mine. Strangely, once passing the lock screen, the screen is responsive, so shouldn't be a hardware problem right ?
Then I installed the new update and I can't get through the lock screen anymore. It responded to some flicks, but never completely unlock. But the rest of the interface (after doing a reset) is responding as good as always.
A test using the camera button, the screen needed two and a half minutes before responding. That's more than twice the time needed to response from a reboot

i having the same problem...
Huhhhh
same TT
http://www.youtube.com/watch?v=SsRtofL9DQA << That's mine.
i have a tmo_de mozart, and when i flashed it with an unbranded rom, problems with the screen lag appeared, now i flashed tmo_de back and its as good as its supposed to, after 1 month
Had all kinds of touch screen lag problems with my friends Mozart, but lastnight i flashed the stock ROM again and it seems to have VASTLY improved it!
It was like the above video, but now its a million times better, but still misses the odd first swipe when unlocking.
Hi all,
I have a little strange problem...
I've read threads people report they have a problem with the touch screen calibration (gets jittery, activates parts of the screen without touching them, etc.) when they charge their SG2, but when they disconnect it the problem is solved.
Well, I have it all backwards.
When my phone is charging, it acts fine. When I disconnect it, the touch calibration gets all funky.
Any ideas on what to do?
Some specs:
It's a I9100G, and I recently went to a phone lab and changed my screen (got broke). Running CM10.1 latest nightly.
Thanks in advance!
Hello mates.
I've got some issue with my desire x touch screen. It is becoming unresponsive.
The whole thing started like 1 month ago. I've noticed that as my phone gets hotter (playing games, using internet) my touchscreen was slowly becoming unresponsive. Firstly I was unable to scroll down my notifications (only the narrow bar at the top was not working) and then it came to a random places of screen, so I couldn't even write sms message. The thing is that it is not unresponsive at all. When I press certain unresponsive area it finally detects the touch. I tried everything, from wiping my screen with a soft tissue through removing battery and sim and sd card to wiping dalvik and cache. I've noticed, that after night the problem was almost gone. And again, after using phone for some time issue occured again. I figured that flashing a new kernel might be a good solution. And it helped and I was happy.
Unfortunatelly, yesterday problem returned. But as you probably suppose - flashing kernel ain't helping. I've also tried other methods mentioned above, but the only thing what helps a bit is leaving the phone unused for like 1 hour or so.
Do u guys have any ideas, what can I do to repair it or to fix it? Any help will be strongly appreciated

I have a similar problem after replacing touch screen. I have found the source of the issue, it could be similar to yours.
My touch screen at the bottom was glued to the LCD in a short line and the adhesive was probably touching part of the LCD cable that goes underneath. I used a hair drier to warm it up and lift off the touch screen. That way there is no bad interaction between the touch screen and the LCD. Haven't had this problem since but my touch screen is unfortunately a bit lose this way. Even now, whenever I push the navigation part of the touch screen too hard, the problem comes back. I will need something to isolate the bottom part of the touch screen from touching the LCD. I will keep you updated if I find a final solution. In the meantime, it could be worth trying it on your phone too.
I think I will just get S-OFF, revert my phone to stock and give it back for warranty repair Anyone of you guys did this? Did 7 vibrations at boot void your warranty?
I'm thinking about warranty repair, cause my bro has the same phone, but full stock, not even rooted. And he got simmilar problem to me, but with less intensivity (it just comes and goes once in a while). Also recently I got this phantom touch problem (after enabling show touch in options I saw my phone is detecting some touches in specific areas) So I think warranty will be the only option :/
