Having problems with the touch screen on my sensation and this has now happened on my secound phone! both phones were ok out of box but after a few days first noticed problems from lockscreen as phone would not always unlock when draging app icon into circle then slowly geting worse until would take several swips on screen to even unlock! then started noticing similar problems in norm opperation? sometimes works ok but some times freezes up have tried factory reset and no differance. very strange having this problem on two phones?
Does the touch screen stop working completely?
Mine did that on Monday, had to get a replacement.
it seams to stutter once awake works slightly better? but still not responsive
I've noticed that the proximity sensor and gyroscope are being used aggressively to filter accidental screen presses.
For example, if I place my sensation flat on a table, the lock screen is very hard to unlock. If i place my other hand near the proximity sensor at the same time (or tilt the phone towards me) it unlocks easily. Until I identified this functionality I was beginning to think my right index finger was unsuitable for touch screens (since when placed on a table I tend to use my right hand, but otherwise use my left to unlock).
Hopefully this will be tweaked with future updates.

Many thanks I hope itd that simple?
I am having the exact same problem, for example on the lock screen I would swipe up but the ring will move slightly, and one icon I.e the camera icon will move towards the ring, another grip which is buggin me is that it will miss screen taps, I.e when texting or clicking an icon one tap will go unnoticed by the device resulting in either a missed letter, or the app not opening. This also goes for the 4 command buttons at the bottom, it happens on these too. I also get the occasional lock up.
Factory reset did not work
All of you are you using Sense, and no other launcher?

Had the exact same issue on my first phone but i was using adw launcher, not installed it on my second phone and had no issues at all

I am currently using launcher pro, but even using the htc stock launcher the problem still arises. When I did a factory reset, the problem was still apparent when entering my pin number for the first time.

As I stated before, I experience this problem but it only occurs when the phone is laid flat and my hands are well away from the proximity sensor at the top left of the screen. I can say that the part you are describing with the lock screen is 100% the same problem I come across in certain situations.
Please test to see if the problem is still present when the phone is tilted in your hand and, if you are laying the phone flat when you experience the problem, try putting your other hand near the proximity sensor when you try to unlock.
If this happens as I describe then it is most likely a software bug which only affects users who have particular phone use habits.
Saying that, as you are having quite severe symptoms, during general use, it may be that you have a faulty proximity sensor in your phone - leading to missed screen taps when the phone thinks you are not touching the phone.
Well I laid the phone flat and unlocked it no less than 20 times, each worked flawlessly no problems at all..... Seems to have me baffled
Yes I've been having the same problem. First noticed it when trying to unlock it (phone was lying down), couldn't get the circle to move. Have had one complete touch-freeze. No input possible, however volume and power button worked. Took the battery out, restarted, and it worked fine.
I notice that input can be difficult sometimes, hit and miss or just have to push harder. Strange. Seems like a software issue to me.
edit: just had the same issue - circle wouldn't move. After picking the phone up I was able to unlock it, however still not as easy as it should be, a bit jerky.
Both my evo and my g2 had a grounding issue, for example if I had the phone laying down on the couch or bed, the screen would not respond to touch but if touch the phone with a finger and try to unlock it with my other hand it would work normally. So it seems to be a common problem with some HTC devices

The wildfire (my friend's got one) has this problem too. You have to keep touching the metallic housing for it to detect any taps.
You are correct, aim1126. I never considered grounding to be the cause but after re-testing it clearly is.
I guess it is a side effect of having a conductive unibody. So basically there will be no software fix, we just have to keep constant contact between our hands and the unibody. I wonder whether a rubber bumper would actually make this problem worse?
Edit:
Actually, the screen seems to adapt to not being grounded properly after a couple of presses. It works fine for me by the third time I touch the screen - weird. Well at least it is only a minor annoyance!

My wife uses a G2 and I wouldnt call it a grounding "issue" honestly seems like more of a feature to make sure you ment to engage the screen.. Its kinda cool IMO
As far as the screen being laggy this sucks since I wanted to upgrade from my Vibrant to the Sensation.. I also am not sure its a software issue you guys are having.. I am running Sense 3.0 with gingerbread on the G2 and it is very smooth.. The option to silence a call or tirning on speaker phone by turning the phone over is neeto torpedo..
I'm having the same issue, from lock screen I drag the circle up and it just stutters. After a few tries it usually works, once unlocked the touch screen appears to work fine. I'd expect the issue would continue after unlock if it was a hardware issue.

I made a video about the issue here, where you can see that the touchscreen problems do indeed persist after unlocking. Especially when typing and scrolling.

That's very bad. Flaky lock screen is not good, and the example of not being able to scroll through apps without it running one is a killer. There are many times when scrolling through a list of selectable items is necessary.
Are you going to exchange the phone?
Have my hopes set on the Sensation, so would really like to find out what the resolution is.

My G2x screen has been very jumpy. It's been registering touches on its on. Pressing button randomly, typing random letters on the keyboard, and jumping around the screen. I have been having the same problem this guy has been having.
http://forums.t-mobile.com/t5/T-Mobile-G2x/My-G2X-is-HAUNTED/td-p/865881
I wanted to know if this problem hardware or software related. Because I think I am going to send it back for a replacement. I don't wanna be out of my grace period to find out this Where's Waldo-like Gingerbread update didn't fix this big problem of mine. =(

Do a factory reset to rule out software issue.
i would say it's probably a defective touchscreen.
lol @ at the guy in the first reply who tried to blame it on a task killer
Oh no.
Well, I did a factory reset to see if it would stop but it's still there. Still selecting things randomly and jumping around the homescreen. I downloaded multitouch tester to see what the problem was. In the upper left corner of the screen, that's where it registers touches by itself. When I place my finger on that part of the screen, the dot moves around erratically. But when I place my finger on another part, the dot stays in place.
I guess this might be hardware related. It's just odd because I haven't even dropped it or damaged it. It happened out of the blue. Oh well, time to return it.
Mine does that when its plugged into incompatible wall chargers.

Issues with touchscreen being unresponsive.
Important Isuue usually appears at least after a week of owning the device
Quick test:
Lock device. Unlock, launch camera app in the lockscreen, take picture, try pressing back button, see if it responds straight away or with a delay. Test it with all apps on lockscreen.
Issue unlocking ? I.e dragging circle to the middle?
Bottom of a screen not responsive sometimes.
Back button slow to respond.
Apps launching when you try to change screen, i.e. phone registers swipe as a press.

CAUSE Grounding pin not touching back cover, which causes (by the looks of it) build up of static which messes up touch screen.
FIX Best to use in conjunction with fixes below.
POSSIBLE FIXes if above doesn't work, which it should, but don't expect immidiate results.
1.Shut down phone and pull battery out for at least an hour (i recommend overnight). Press power button as to turn phone on, which in theory should discharge all the left over current in the hardware.
Give it a go and let me know if it works.
2.Letting battery discharge till phone turns off,put on charge and don't touch it till it's full.
I want to thank abrown0809, eliteone, stuart0001(legendary patience ), zmfl, maschenazi, nugzo and all other people i forgot to mention for sticking with me while trying to work out FIX. Thanks to all the posters too.
I take NO credit for the fix.
Poll is here to show how many people have this problem to HTC, not to work out what percentage of users have it, as it will definitely be incorrect.
Vote yes if you EVER experienced touchscreen problems, even if its gone now.
PETITION for HTC to admit that there is touch screen problem.

HT157V No issues
HT15HV80XXXX 6/1/2011
HT15BV80XXXX 6/8/2011
HT15EVXXXXX 6/13/2011 Current Device
Had big problems with the first two, both returned... Third is an improvement, however:
Seems to be a problem with the application data screen (where you can move to SD etc...) all of the data goes mental and the buttons flash sometimes causes a crash that only battery removal cures...
Back button seems to forget to work when the screen unlocks, normally returns to normal after several actions
Unlock screen is hard to unlock sometimes... helps if you are holding the device...
Screen is sometimes slow to respond
SD app icons on home screens do not regenerate after reset...

Edited first post
HT15JV - no touchscreen or lockscreen issues so far
Only real bug is that non HTC widgets sometimes get flickering rainbow coloured stripes but they are strictly attached to the widget and vanish once I replace the it. So this should not be a display problem especially as the HTC widgets are never afflicted.

HT15RT, may build and ship date
all of the above in terms of problems. unlocking problem, bottom of the touchscreen not being responsive, swipes registered as taps fairly frequently, issues with wifi cycling and never connecting, and it has ruined the SD card it came with (do the point that it gets detected by my win7 computer but crashes explorer, and on my mac it just isn't detected) as well as the 16GB microsd I foolishly swapped in from my DSLR.
Did I mention that I still am absolutely in love with the phone?
Hmmm, still a bit random.... We just need to find a common factor. If anyone spots anything in common, just mention it, even if you are not sure.
I appreciate this thread. I am still considering purchasing this phone but the two major hold backs are the wifi signal deathgrip issue and of course the touch screen. I kinda went through this debacle with the mt4g and don't really want to go through the hassle again of finding a working model.

Did those with or without problems use a screen protector?
I left the stock screen protector on my unit and it works beautifully. Maybe because the touch screen unit is slightly displaced, static build up on the gorilla glass causes issues with some unit?
HT15RT works perfectly
Hello!
A few days ago my desire s started acting very weird. Sometimes the four buttons don't work (home, back, etc.) and sometimes my finger gestures aren't recognised. For example if I want to call somebody and then click on the home button my device thinks I pressed on the call button instead. Or if I am in some menu and I click on some of the four buttons, my desire s thinks I pressed the display somewhere else on the screen. Sometimes it helps if I turn the display off and then immediately on. But after a few clicks the same behaviour again.
I wanted to install a custom rom anyway, so I did a full wipe and installed Fallout. But nothing changed. Do you think my device is broken?
Ive had this top my screen was replaced under warranty mine was stick at the time

Your phone has somehow been exposed to high temperatures?
Not that I am aware of. Though these things happened when I was out in the garden playing with my phone while the weather was pretty hot (about 30 degrees). But I don't think that you mean that with high temperatures, do you?

Excessive heat can lead to detachment of the adhesive that is bonded touchscreen, it's not making edge contact. It happened to my ex HTC Hero on a sunny day (the phone was black)

It happened here sometimes with gingerbread stock while on *charging*! Only when charging. It's not happening on ICS RUU update.
I had the same problem a fortnight to a week back... exactly as OP describes (phone 6 months old from new). I've factory reset and changed ROMs, the problem remains.
But since 4 days now, my phone has become completely unusable.
The back and menu touch buttons don't work at all now. And some area's of the screen are dead, and brown coloured.
It's a PITA every time I have to type anything as my keyboard keys don't work at all (and other area's). Then, randomly, after 2-10 seconds, none of the keys or phone touchscreen will work until I off->on the screen.
Anyone please any idea of a fix (to me, it looks like hardware)?
If not, anyone ANY idea how to add a back button somehow? Or even assign the search button the back button function?
I desperately need the back button working. TIA!
I have exactly the same problem with my Desire S (stock ICS). Anybody of you solved this?
Thanks.
I have a strange occasional problem with my sensation, sometimes very stubborn and persistent. While unlocking the phone, i don't get the lock screen but a snowy white screen (as on old tv when there is no signal) The phone is not frozen though, it reacts to finger movements and i can unlock it, i could even execute operations if i knew where the icons were, but the screen remains that white. Only after some locking unlocking, or pressing the soft buttons (no rule) i get the normal lock screen or home screen. Sometimes i have to turn the phone off/on.
Does anybody have similar experience, is it a hardware issue or could it be some app issue or what else?
It could be a hardware issue. I've never seen that with any rom or in any situation! Have you by chance tired flashing a different rom to see if the issue goes away? I'd do some experimenting and see if the issue continues on different roms. If yes it's likely a hardware issue. It does look like it but it wouldn't hurt to do some experimenting. Is your device still under warrantee ? I might look into replacement. Has the issue gotten worse? Sadly it seems to be hardware related but it wouldn't hurt to experiment and see if issue still persists. I wish you the best and hopefully you can get a repair or replacement to solve this problem. Best wishes.

The phone is under warranty and it is not rooted, so, I would not experiment with other roms. Several months ago I had the phone's mother board replaced under warranty because the first one died. The problem described above started after the mother board replacement but not immediately, it happens occasionally and not related to any special condition. It does not happen when the phone is unlocked and I work on it, it happens only when it is locked, i.e, when i try to unlock it and press the power button to unlock, it is then that this screen sometimes appears.
