It is a hardware problem

I'm 100% sure it's a hardware problem. I got mine repaired after a shattered glass, and after repair this issue occured. Repair guy can't find anything, but it voided my warranty so I can't get it back to HTC.

A good way to test is by installing Touch Test from the market.

If I run it, lock the screen and unlock, I immediately pull 4 fingers over the screen and see some spots were the screen is not responsive. After some seconds it's responsive everywhere.
[HTC Sensation] exb0:
I think this issue varies from device to device.

My problem has been solved by a wipe.

[HTC Sensation] abrown0809:
I have used the foil trick for over a day now and the problem hasn't some back. I've even gone back to using stock charger.
[HTC Sensation] stuart0001:
It definitely varies from unit to unit.

I'm on my 3rd now and whilst it has intermittent screen issues, when it does manifest it's nowhere near as bad as the previous 2 where I would have problems even slow swiping, having to repeatedly press an icon before it recognizes and missing letters on the keyboard when composing SMS etc.

With the current unit the worst I've had is not recognizing fast swiping only.
[HTC Sensation] zmfl:
I believe you are both incorrect, or actually, both correct :)

It seems there are at least two issues here, both manifested similarly - touchscreen unresponsiveness.

One is a software issue, solved by restarts, wipes, new ROMs, apps. The other is hardware related (grounding), solved by messing with that grounding pin, or by discharging and not interacting with the phone while charging.

Someone might actually have both of these...

I for example have the hardware problem, and no amount of restarts, entering bios, new apps or ROMs does a damn thing. But hardware related fixes helped every time.

Now, I don't know how to fix the software issue permanently, since I don't have it and can't test, but I believe that aluminum foil solves the hardware problem for good.

Has anyone that solved their problem with foil had the problem come back?
[HTC Sensation] stuart0001:
Just a thought on those where the holding the phone without case method doesn't work. It may be due to the shoes you're wearing or the floor you're standing on preventing the static from discharging/grounding. Try again but at the same time put the other hand on a radiator or something else that is definitely grounded.

It's ridiculous that we have to do this but hey-ho, if it works it's worth doing :)
[HTC Sensation] Caspertje19:
I say it's hardware: will get my device back in the next days from HTC repair and they reported that a part of the phone has been replaced and that a software update is done (1.35).

I hope i get to know wich part has been replaced when I receive my phone. I will report back within a few days
[HTC Sensation] someonewhy:
hmm sounds interesting..i got my device over 2 weeks and no problems at all
[HTC Sensation] emzed:
Aluminium foil trick seems to work here (for now...)

OMG!

I had given up already but I tried the aluminum foil trick and it seems to work here!!

Those who want to try:

cut out a small strip of alu foil (about 3 x 1 cm)

fold it (you now have 1,5 x 1 cm)

place it on the inside of your back cover. About halfway, on the right outerside there is a contact

make sure it sticks out about 1 mm

place your phone in the back cover

check Touch Test app for the results

On my phone, this was the only thing that worked. Improvement is 90% here. Let's hope it stays this way.
[HTC Sensation] cdeeee:
Even worse

Still no luck using any of the solutions provided. Unfortunately I am stuck here on this forum hoping something changes.

I went to the HTC service center with my phone today and they said I have to pay over USD$ 300 to have the phone repaired even though it is under factory warranty. I live in China but the phone came from Taiwan and I don't have the warranty card so they won't cover it.

Unbelievable - I am losing serious faith in HTC and am out $700 and have a broken phone.
[HTC Sensation] stuart0001:
Did you give my suggestion a go? It's not in the op so you may have missed it :)
[HTC Sensation] cdeeee:
I actually tried placing a wire from the grounding wire on our radiator directly to the tin sensor and then the sim card cover and nothing. Well it seems to temporarily improve the scrolling and smoothness of the screen movements but does nothing with the screen alignment problem (push a spot in one place but chooses about 5mm higher than the place I touched). Thanks for your ideas - I will keep watching for new ideas.
[HTC Sensation] stuart0001:
The alignment issue sounds like it might be a separate issue to the responsiveness problem.
[HTC Sensation] Towle:
Couldn't this be something as little as having to recalibrate the touch screen?
[HTC Sensation] stuart0001:
That was my initial thought but I couldn't find where to do it in settings so I'm not sure you can.
[HTC Sensation] nugzo:
That sounds crazy. I would try again. THese phones arent even close to being a year old yet, dont they have a 1 yr manufacturer warranty? Maybe just call them and try that way. Good luck.
[HTC Sensation] idavid_:
How about touchscreen booster from the market? And if you tried it, did it solve your issues?

[HTC Sensation] GabrielSousa:
i can confirm this after install the 1.45 RUU, i get better battery life
[HTC Sensation] boostedb16b:
Solution works but as I think its still a temp fix... The real issue I believe is drivers... Just my 2 cents
[HTC Sensation] maschenazi:
Today I got a surprising call from HTC who just wanted to assure me that my call has not been forgotten. After 6 weeks since I logged it I filled in their satisfaction survey and gived them low scores. Looks like the right person has seen it. They don't have any more info yet, but apparently they are working "hard" to fix it. :) What a joke ! You guys should do the same when you got 5 minutes. Give them hell !! :))
[HTC Sensation] stuart0001:
Problem came back about an hour ago so I've tried putting foil between the metal plate and the white pad and so far so good. Screen is perfect again. Hopefully it'll last.

One thing I did notice was that the metal plate is a little loose. Is anyone else's?
[HTC Sensation] undercover:
Here is reply i received today to my FIRST conversation with them, which was about 2 months ago

Thank you for contacting HTC.

Recently update 2.3.4 has been released. If you have not received it yet please check it in Settings - About Phone - System software updates.

If you have received update but issue still occur please contact us back in order to arrange inspection in repair centre.

Thank you for contacting us.

Lol, ok, and that is after telling them problem disappears once you turn phone off for a few days....

Let's wait for another on, more recent.
[HTC Sensation] undercover:
Nope, haven't noticed. Glad it helped you.

Any failures with tin foil fix yet?
[HTC Sensation] idavid_:
Yeah, I have creaking on the right side, but I don't have touchscreen issues

[HTC Sensation] nugzo:
How long have you had your phone? What are your charging habits? Always charge same way/place? or wherever you can find a micro usb? If always charged in the same place, what charger and what surface does your phone rest on? Do you ever use your phone while its charging? Thanks for your help..

OP what do you think....maybe we should make a questionnaire like this or similar for people who do NOT have the problem..? Of course you must have the phone at least 2 weeks (1 week possibly) That is the strangest part of the issue.. I dont know of anybody who has had the issue out of the box... /shakes head
[HTC Sensation] idavid_:
Ok. I had the phone for 2 months. I usually charge it during the night and also during the day (I use it a lot). I use the phone while it's charging pretty often. It rests either on a wood table or the bed. I charge it the same way all the time, except last month, when I was charging it on a car charger for 3 weeks. During these 3 Weeks I used it much less. Otherwise I use the HTC cable with a Sony Ericsson adapter for charging. I actually had touchscreen issues twice (for few hours) but a quick battery pull (battery was out for some seconds) fixed it. No issues since then.

Some extra info:

My serial number starts with HT15

Under the cover it says 2011/05/03

I also remove the cover pretty often

Mine is pretty stiff, that's when I decided not to pull it out.

Also my screen creaks too.

The foil fix has been working for me. My sensation is back to being sensational.
[HTC Sensation] eliteone:
Just out of curiosity have any if you flashed the official eu 1.45 update? Any differences
[HTC Sensation] nugzo:
Thanks for the detail. That basically shoots all my theories down lol. again thank you.
[HTC Sensation] Gobstop:
unfortunately joining the club

Picked up the sensation on Aug 6 for my wife

SN: SH17ET

2011/06/27 on backcover.

She was complaining about the phone hanging up on her, unlocking issues etc about 1-2weeks after we got it. I just started playing with the phone and most of the symptoms from the OP are present. I have gone through the suggested solutions but nothing seems to work. I did the OTA upgrade, but didn't help at all. Today at least she reported that it didn't hang up on her, but it can take 5 or 6 tries to unlock, no carousel effect(ends up opening an app if I try to swipe fast). Also no longer getting a 4g signal(only 2g icon shows). I just tried the foil trick and that didn't seem to do too much either.

Anyhow, since I live in California, I have 30 days after purchase to still return the phone. I'm really not sure what to do. Should I try another Sensation or return it completely? What's a current T-mo USA phone that is known to work well without many problems?

thanks

Gabe
[HTC Sensation] emzed:
Well Gobstop, I see many people here with the touchscreen pb, but I know 3 people myself that have the phone without the problem. Myself, I would go for the Samsung Galaxy SII or even wait for the Nexus Prime. But that's just me, being a phone geek who eventually root the phone anyways.

Many people tend to favor the HTC Sense interface over Touchwizz (samsung) or the butt ugly russian-cold-war-style vanilla Android interface.
[HTC Sensation] divadiow:
this is balls. this just isn't good enough
[HTC Sensation] mert_im:
i tried all to solve that problem.. but no way! its hardware problem.. i ll send my phone to htc :(
[HTC Sensation] maschenazi:
Just got off the phone with HTC (they called me again today:eek:). They asked me if I have the latest update (2.3.4) and they told me they have fixed the touchscreen issue with this update. As far as I know, as yet, UK unbranded Sensation didn't get the OTA, but yesterday I had enough of waiting and installed the 1.45.401.2 RUU. Anyone with the latest update still has the problem ?

I will get back to stock charger and try to play with the phone while charging to see if the issue comes back. Anyone knows a better way to re-introduce the problem ?
[HTC Sensation] stuart0001:
I'm running that RUU and I think it may have improved the issue but it certainly didn't fix it 100%
[HTC Sensation] what9000:
I just gutted the phone again and tried to bend the contact points for the case to the grounding pin a bit more. I also tried the tinfoil trick. I am not sure which if any is changing it, but I can unlock the phone with only minor issues if I use widgetlocker and it is on the left side of the screen. the right side is a wash. Nothing works over there. Additionally, once unlocked this way it seems to be responsive enough to carousel instead of being an unresponsive waste of money.
[HTC Sensation] aliensmille76:
2.3.4 doesnt solved anything!!!
[HTC Sensation] Bastaerd:
Used to have the touchscreen issue as wel, but flashing Leedroid's ROM solved it for me.
[HTC Sensation] GabrielSousa:

[HTC Sensation] Vipeout:
I've had the Sensation for 2.5 weeks and no issues so far... until now. Today I wanted to try for the very first time a custom ROM. So I backed up all my data With Titankum backup. THEN in did a factory reset via the SD Card Menu. Well as soon as the reset was compete I noticed my carousel wouldn't work anymore. Also the screen got less responsive, swipes were recognised as taps.

I still flashed two different custom roms and thought the problem was on the. But retuning to me stock Rom didn't change things. So now I have this drwaded issue as well. In my case, it happened RIGHT AFTER factory reset.
[HTC Sensation] nugzo:
You're just over the normal failure time. If you had the phone plugged in and were transferring files, wiping, resets etc while plugged in then you gave it the out it wanted.Has happened to most of us. Now just ride the train. Find out what fixes it the quickest for you then use some tips in this thread to keep it from coming back. For me its never charging unless in dock in car. I keep extra batteries charged and replace them when needed. I know its a pain in the ass but when this phone runs right its freaking amazing. When the screen is jacked up its not worth owning. It will continue to mess up unless you find a routine that works, and stick to it best you can. Good luck!
[HTC Sensation] undercover:
I've been trying to reproduce issue for four days now, and here is result. Let's see if it comes back after a week or so. Worst part, if it doesn't come back,I've no idea what fixed it.... Let's wait and see.
[HTC Sensation] umd:
Did you flash full RUU? Because with 2.3.4 custom ROMs you miss some chipset drivers.

Flash 2.3.4 full RUU, run Revolutionary then flash the custom ROM you want.
[HTC Sensation] WarlockW:
Yeap .. Mine does the same thing .. just like the videos ..

I was gona make a vid of this too ..

People with a cover / case or like me a leather case

this maybe the problem why your phone isnt working right

This freaking phone has more bugs . then my basement!
[HTC Sensation] nugzo:
Playin tricks on you tinky1 lol. You know just as soon as you think its right you wont be able to answer a call lol :) Good luck! Have you tried the full RUU?

Anybody tried the full RUU ?
[HTC Sensation] undercover:
Yup, full RUU yesterday for a different reason though.
[HTC Sensation] umd:
So are you saying that it solved after flashing RUU?
[HTC Sensation] dragona:
I am on my THIRD Sensation in a fortnight, had to keep swapping them out as my first and second handset had peculiar display glitches And it happened on HTC widget.http://www.youtube.com/watch?v=RADIEB_d8-E
[HTC Sensation] Tirozz:
Small question; how did you get the transparent Apps-Phone-Edit(?) bar?
[HTC Sensation] undercover:
No, I've been struggling ( can't believe I'm saying that ) to reproduce issue for while now. And I don't know if its temp or permanent fix, and I tried so many things that I don't even know what fixed it.
[HTC Sensation] Vipeout:
That`s what I`ll do. And when somethig new comes out I will have it replace through warranty! Gonna have to send it in 3 times but well..

I just noticed it works again. I connected it to the USB 3.0 Port of my notebook, had it mount as as external HDD and now it works again, even after disconnect.
[HTC Sensation] cristy7610:
i don't know what cause this problem but my phone have this issue for about 3-4 days and after that the issue gone for good...the only thing i do is that i never use me stock charger and i flash the rom with leedroid 2.2.0....
[HTC Sensation] abrown0809:
I've been using the foil trick for about a week now and the touchscreen issue has never come back. Maybe some people should try it for an extended period of time. Maybe trying it for a hour or two isn't enough.
[HTC Sensation] undercover:
Willing to share a how to with pictures?
[HTC Sensation] stuart0001:
It's been working for me too. All I did was tear off a bit of tin foil and folded it a couple of times to give it a bit more thickness and placed as shown in the photo.
[HTC Sensation] invisiblebm:
The folie trick did it. I did not saw my carrusel turning like this since I bought my phone. Everything is perfect now. This is the exactly solution, no kernels , no updates. Thanks !
[HTC Sensation] zmfl:
If messing with the grounding pin in any way solves your problems, there are several ways to fix the phone permanently. Putting the foil in, like stuart did, is one of them.

I've been preparing a thread on this for a while now... Here it is:

[HTC Sensation] undercover:
Well, if it works for.you, then it is a FIX LOL. So all it was is just misalignment of body and cover. ****, you got to be kidding me, that simple. I reckon we should claim money from HTC for testing and finding problem. Imagine how much they would have to spend by testing it themselves. :) E-mail to P. Chou anyone? :p
[HTC Sensation] kefflar:
In my case I'm not sure what helps, but I do two things:

1. I Let battery discharge till phone turns off, then I remove battery for a while(couple minutes), after that charge the phone while it's turn off until its full, but screen was still unresponsive.

2. Second thing what I start unlock phone with cover proximity sensor (not fully covered) only near by. After I do this couple times touchscreen starts response normally.

Now I'm charging the phone everything available methods. Stock charger, USB cable from my printer, laptop, friends stock Wildfire charger, no changes. Everything works perfect since 5 days.
[HTC Sensation] undercover:
Fair enough mate, but read 2 last pages and you'll see the FIX. You won't have to bother with proximity sensors and such...
[HTC Sensation] kefflar:
Perhaps You right - but now I don't need to touch the phone. Only one finger is needed to unlock the phone. Without static field issue.
[HTC Sensation] eliteone:
The, tinfoil fix will do the same thing ;) I can unlock the phone with one finger while it sits on the counter. Try it, it works well and is a simple fix :)
[HTC Sensation] stuart0001:
4 days with the tin foil and my screen has been flawless. I'm going to give it another week then remove the foil to assess if that was definitely the fix.

I've been trying all the things that may have previously caused the issue so it's starting to look like a solid solution. Thanks again to those involved in coming up with the fix :)

PS. Am I alone in finding the carousel a little therapeutic? I guess it's born out of the frustration from when it hasn't worked :D
[HTC Sensation] eliteone:
LOL! Ya i was entranced by the carousel for the first while after fixing the screen :)
[HTC Sensation] Gobstop:
seems to be fixing itself

I posted last week about the errors I was having with the touchscreen. I just now saw that a fix had been posted, but I was going to report back that after doing the complete discharge and charging(but not touching) the problem seem to be getting a lot better(I was going to go return in on Sunday, but by Saturday it was mostly behaving). It's odd, it has been a gradual improvement. The only time the lockscreen does not work quite right is when the phone is not being held(e.g on a table or other surface). Otherwise, it seems pretty good. I can even get the carousel effect going most of the time(not that it's useful, but sure is pretty). I had tried the foil trick, but it didn't seem to help at the time.

thanks to tinky1 for setting up this thread, it has been a lot of help.
[HTC Sensation] zmfl:
It's good that the problem is going away, but unfortunately, it will come back... It always does. We all went through your troubles and we were just all as puzzled as you are, or more...

If discharging works, the problem is down to static electricity. And if it's down to that, the fix in the other thread will work permanently :)
[HTC Sensation] bigstevo24:
Several weeks ago I reported the touch screen problems. I also mentioned I changed my charger to the htc desire charger. Since doing so, I never to this day had another touch screen problem. The phone works amazingly well. All issues are gone. Problem solved.
[HTC Sensation] Gobstop:
argghhh

@zmfl,

how right you were! My wife reported back that at about midday it started having issues again. Lockscreen is acting up, and she was unable to make some phone calls because numbers on the dialer screen wouldn't work. I will try the discharge trick and see if it helps. I was so excited to have her phone working normally again......
[HTC Sensation] Gobstop:
FIX, how long till takes effect?

Never mind, just read the additional thread, saw that it should be instant, or if not, give it a couple of hours, will see tomorrow..
[HTC Sensation] aliensmille76:
I charged my Sensation also with my Desire Charger and I got the issue as well. Same as the Sensation charger.
[HTC Sensation] maschenazi:
Been trying for almost a week now to replicate the problem... without luck so far. Went back to sensation charger, been playing with the phone while plugged in for at least 15 minutes a day. I installed the RUU, not the OTA update and when HTC called me last time they said that the 1.45 update should have fixed our issue. I have been trying to prove them wrong, but so far I could not. Will try for few more days...
[HTC Sensation] nugzo:
I tried the aluminum trick when the silver pin was first mentioned, id didnt work for me. I had a hell of a time with it all day with the aluminum foil fix. Finally had to leave the battery out all night to fix it. Not sure if i want to test it again. I'll wait for some more feedback.
[HTC Sensation] undercover:
Put foil back in and see if problem comes back. I think it still takes a while to get rid of the problem, but once its gone and foil is in place it shouldn't come back.
[HTC Sensation] guitargod:
The fix with the pin worked for me...BUT ONLY FOR ONE DAY.

Then i couldn't make it work again.

My Sensation is now on it's way to the repair-service.

Just for my interest:

could the service-center fix the touchscreen-problem for someone? How do they repair the touchscreen-issue? Does someone know?

Greets
[HTC Sensation] craigspc:
Bending the pin worked perfectly for me, but it seems to keep coming back.

Does anyone with this problem also experience the creaking/cracking sounds when pressing the screen in the edge or corner (not too hard). It's almost as if my back cover is warped a bit.
[HTC Sensation] zmfl:
They don't. From what I gathered you just get a new device.

The cover gets loose in time for most of us. That's probably why you need to bend the pin.

If the problem keeps coming back just add tin foil.
[HTC Sensation] stuart0001:
A week now and screen has been flawless with the tin-foil trick. It's the longest its gone without fault.

One minor observation, whilst plugged into USB and on my PC desk, I couldn't get the ring to unlock until I picked it up off the desk So I guess, whilst the foil aides contact between phone and case, it still needs the human touch to fully discharge.
[HTC Sensation] craigspc:
Unfortunately it doesn't seem that simple. I've now realised that even with bending the pin and adding tin foil, the problem comes back within a minute of sitting on my sofa with my feet on our fluffy carpet. It seems like the phone is just hyper-sensitive to static. If I go and sit somewhere else, it'll spin away happily after a couple of minutes..

One of the easiest tests I've found is to go to the home screen and try flicking between screens to activate the carousel spinning motion. On the sofa it won't spin (just opens apps and keeps stopping).
[HTC Sensation] craigspc:
Despite what I said above in my last post - I've just thought of something that would suggest (to my unqualified mind) that I am wrong about the sofa/carpet business and that it might have been a coincidence that it wasn't working on the sofa.

If this really is a grounding issue, wouldn't/shouldn't the phone work perfectly if connected to a PC via a USB cable? Shouldn't that earth the phone properly?.
