Hi guys this issue really strikes when u connect usb cable....by in any case (its my guess) since the touch panel is now confirmed being of different make can we all confirm if the prob is with a particular panel?
[HTC Sensation] motoi_bogdan:
different chargers produce those 5v required for charging in different ways. It could be that the ground connection for the original sensation's charger suffers from some voltage ripple or simply too much noise over what otherwise should have been a smooth 5v with almost no parasite signals.

A simple way to test this would be to replace only the charger, not it's usb cable. This way we can rule out any problems with any particular microusb jack or cable.

If it is the charger that's causing the problem, then i'll crack one open to see what's causing it.

Unresponsive Touchscreen ( Sensation )

I too have the touchscreen issue and I find it quite sad really as I have been a huge HTC fan for some time now and was expecting this to be a great device. Unfortunately its the only HTC unit I have ever had a problem with and to be honest, I am disappointed.

Nothing out of the ordinary happened to the unit, it was 8 days old, and just started to act laggy at first ie....slow scrolling, carousel effect sometimes working sometimes not and over a period of approx 1 hr it just got worse and worse. The only thing that I could think of when it happened is maybe I used it while charging, thats the only thing that could have triggered it. Over the course of the evening it steadily got worse whereby even the lock screen clock would not update and the clock in the notification bar was stopped completely, the battery icon stopped working and homescreen widgets started to wobble very slowly or get stuck in a sort of a resizing loop.

Also - and I dont want this to sound funny or stupid but one thing that actually appeared to happen was that the screen itself was clammy or sticky and just was not smooth to the touch when swiping, cleaned but would feel that way again after a couple of swipes, I know that sounds ridiculous but it was happening so maybe it is a sort of static issue, grounding problem???

If anybody has any feelings on this Id appreciate the feedback

:(

Maybe HTC does already know what it is:

Send mine device in after contact with HTC.

In the status repair log, the following 'intresting' happened in relation to the time:

at 9:06h Repair center: pending (Reparatie repair center - In behandeling )

at 9:10h Repair center: internal repair: waiting for supplies (Reparatie Intern - Wacht op onderdelen)

(translated from dutch to english).

If they track down the problem within 4 minutes, they must already know what part to replace....

Nobody else has a repaired device from HTC?

Only exchanged ones?
[HTC Sensation] undercover:
It would be helpful if you could enquire what parts been changed. Also, report back wherever problem is gone for good please.
[HTC Sensation] jetheridge:
Hi Guys,

Been reading the post with interest, as I've got this device and love it.

Sadly got the same issue with the lock screen.

Here is my THEORY... It's 100% software issue with the sense lock screen.

If you install a different lock screen, the problem goes.

Then, go back to the sense lock screen and the bug is back.

The fact that after reboots and taking the battery out etc fixes the issue temporarily is simply down to the device not finished loading up all the services that run in the background and the like.

I reckon that there will be a fix out for this soon that will do two things...

- Increase the sensitivity of the touch screen

- Reserve more system resources for the lock screen or so it sits with higher priority.

Anyway just a theory of what I've found.

Cheers,

Jason.
[HTC Sensation] typhun666:
possible HTC get out of fixing screen issue clause

According to various sources that I've read the unlock we are waiting for ''aka unlocked bootlocker'' requires users; such as ourselves to sign an agreement that voids our warranty, I may be being a little paranoid but surely this would enable HTC to then refuse any issues with unresponsive screen issues etc as we are all out of our warrenties thus enabling HTC to get out of fixing this issue?
[HTC Sensation] edis_feyziev:
i get my htc sensation from service and they updated the software. My SW 1.35 before service after service SW 1.35.

Its exactly the same but now it works...

Today is the second day of my usage of the phone 1 charged with 550 mA charger, 2 charge with htc sensation original charger with output 1A.

There is no issues yet, im using silicon case 2 charge too.

When i get the issue i will report again.

Thank you
[HTC Sensation] chacik:
So far so good

I've had my Sensation for 3 weeks now and I have no problems at all. Touch screen works great, so does wifi and the speaker. I've noticed one thing, though. I just have a bit different S/N number than most of you, guys. Mine begins with SH16TV and not HT16 or HT15. My software version is 1.35.401.1.
[HTC Sensation] derkie:
My replacement Device have the same S/N prefix and as I have mentioned in my post in this thread, I use it as normal as what's expected and doesn't go as warm as my previous defective device.
[HTC Sensation] p0wer_b0y:
Same touchscreen issues here after using for a month..

My Sensation just came back from HTC and they replaced the following:

1. LCD Touch Panel

2. Phone's Main Board

3. Revert back OS from 1.35 to 1.28

HTC Care reported this was due to hardware problems..

So far everything is ok now and screen is very responsive again.
[HTC Sensation] lilhugo:
Hello,

I currently have 2 Sensations and they both begin with SH16LT, and neither of them have a touchscreen issue. I've loaded up plenty of apps that came with the phone such as Qik and Tmobile TV as well as the apps on the lock screen.

I did change email to gmail though.

I've had both phones for about 2weeks already. One has already been left out in the 100+ degree temperatures (my brother's not mine) and that has no issues with the touchscreen either.
[HTC Sensation] k.aalai:
Bizarely mine has been working perfect for the last couple of days, after a week of non function.

It works with case, without case, unlocks great etc...

No idea why it has fixed itself for now, I didnt do anything to it.
[HTC Sensation] nugzo:
Please keep us informed on your repaired sensation. I sure hope its fixed.

Replacing the touch panel and LCD is basically a new phone. including labor its probably more than a replacement phone...
[HTC Sensation] lovelypinklotus:
I Have had my Sensation for a month and its only one ive had... And I had the screen problem as well...

But interesting enough I ordered the Skinomi Screen Protector

And it cured the unlocking problem and the screen problem... But when I removed it (the edges were coming up...) It came back...

Dont know if that will help...

But it worked for me...
[HTC Sensation] thebigham:
I put on a screen protector on my sensation yesterday and the screen became extremely unresponsive on the lock screen. It usually takes me two tries to unlock the screen. After i put on the screen protector, it takes me at least tries!! Then i leave it charge overnight. When i woke up, the issue went away. Now it only takes one try to unlock. This is so RANDOM!
[HTC Sensation] nugzo:
how long did you have it on?

[HTC Sensation] aliensmille76:
Makes it just a little bit better for me.
[HTC Sensation] stuk71:
Putting my clear case-mate back on and charging with my Desire charger has rectified the problem for me.
[HTC Sensation] JamesRC:
I've been experiencing the touch screen issue today - lots of mis-typing and not actioning my touches.

I took the front off and cleaned the proximity and light sensors at the top of the phone and it seems to be working much better now...

My theory - if the prox sensor is polled and appears to be blocked the touchscreen sensitivity is turned down (so, if you are on the phone, you do not accidentally press a button) - but in my case dust was covering the sensor so the screen was unresponsive.

Will post back any findings.
[HTC Sensation] undercover:
Sorry to hear you got them problems. Your theory doesn't explain how come problem gets fixed after a while for many. Sensor doesn't clean itself.
[HTC Sensation] stuart0001:
5 days in with my 3rd Sensation and screen still good. I've avoided using the phone whilst plugged into AC to see if that helps but I do use it when plugged in to USB because of modding etc.
[HTC Sensation] JamesRC:
It could easily be sufficiently cleaned when moving in/out of a case or pocket...
[HTC Sensation] kgbkny:
I've had my Sensation since June 15, and haven't had any touchscreen issues at all. I kept the factory screen protector on until I got the HTC screen protectors, and the screen performance has been consistent.

My brother-in-law just got the Evo3D, so I had a chance to give it a test run yesterday. The phone was much more responsive than my Sensation and the home screen carousel effect could be triggered with one flick of a finger. With the Sensation, it usually takes 2-3 flicks. The Evo3D, however, didn't have a screen protector. I've never had a chance to test my Sensation's screen sensitivity without a protector, so I can't objectively say that the Evo3D is more responsive than the Sensation. However, without a screen protector, it was definitely more responsive.
[HTC Sensation] Phateless:
Haven't used my sensation enough to give feedback but my glacier definitely has problems while texting.
[HTC Sensation] stuart0001:
6 days in and I now have the problem on my 3rd device.

It started this-morning when it would sometimes take 2 attempts to unlock the screen and now the screen has become unresponsive the same as before.

The date on all 3 on the battery cover has been within 3 days of each other so it appears they are all coming from the same batch and it looks like I have no way to influence which they pick.

I'm going to think about it for a few days but I'm sorely tempted to swap for a SGS2. I just can't be bothered with the constant swap-outs anymore. :(
[HTC Sensation] k.aalai:
More news on mine:

After reporting before that mine had started to behave itself, its still seemingly working perfectly well.

What about you guys? Posts have dried up a little here, so whats happening with your handset, still screwed up, or did it magically start to work like mine?
[HTC Sensation] mmeyer4663:
Ever since having the touchscreen issue after having the sensation for about a week, way back in June, I haven't had any problems since. Phone has been working great.
[HTC Sensation] undercover:
Well, i just keep on top of the problem. HTC hasn't got back to me yet, might have to do another report.
[HTC Sensation] chadsin:
I've had mine for 2 weeks and every now and then the lower portion of the screen is unresponsive.
[HTC Sensation] moh0:
This problem IMO is probably temporary. I had this problem about 2 weeks after getting the phone and it persisted for a couple of days. Ever since, my touch screen has been the most responsive I've ever used. Dunno how to explain that. Maybe the screen has a breaking in period?

Also on a side, I emailed HTC about the problem when I was experiencing it and received this response:

I did use the built in task killer quite frequently when I first had the phone. Don't remember when I stopped using it. I just let my apps do whatever they want in the background nowadays. You guys should stop using task killers if you are still having this problem and report back if it helps.
[HTC Sensation] kris.sh:
Still having the issue intermittently :(
[HTC Sensation] champkongen:
Same story here. All good.

Turned off tell htc and told htc in a mail :) but works now.. Still

Could people having the issue at this moment try the link above for a fix please. according to that thread it has fixed all that have tried except possibly one person.. I'm going to charge mine like i used to so i can get it to mess up so i can try that threads solution. Its a touchscreen optimizer app. good luck and please report back here as well as that thread.. Thank you darkburst1991 for sharing. If it works for yall please thank darkburst1991 for the link. Its on the previous page. Also dont forget to thank the OP who created the thread.. Damn i hope this does it for everybody. I have never wished i had the problem but i do now so i can try the fix :)
[HTC Sensation] stuart0001:
Hasn't made a difference for me :(
[HTC Sensation] vegetaleb:
This bug is even worse than death grip :eek:

I hope HTC or any dev will sort out a solution.

back in the N1 days and now sgs2, I had problems with touchscreen only while charging, so it's probably a battery/voltage issue
[HTC Sensation] stuart0001:
Just to add that my issue is on a minor level at the moment where I can't fast swipe (eg can't get carousel) but I can usually unlock ok and it seems to register all presses ok too. This is both before and after running the aforementioned app.

I'm starting to think that it's user related too in terms of causing static from certain clothing for example. How else can you explain that many don't have the issue but others like myself have had multiple units with the problem? :confused:
[HTC Sensation] nugzo:
I feel ya. on my 6th sensation right now. All had it :(
[HTC Sensation] stuart0001:
I tried method 3 last night but to no avail. Will try method 1 tonight.
[HTC Sensation] undercover:
Stuart, try it again.
[HTC Sensation] stuart0001:
Will do. Just to check I'm doing everything ok:

Wait until phone shuts itself off

Plug into PC USB cable to charge

Wait a couple of minutes

Turn On

Leave overnight to fully charge and don't use whilst plugged in.

Fastboot was enabled last night so I'll try with it off tonight. Any merit in removing battery & cards for a duration before plugging into charge?
[HTC Sensation] nugzo:
Still experimenting. I never plug my phone up actually. I have extra batteries and a wall charger for the batteries. I just charge them that way and have had no issues since. although it has only been a little over a week, its working well.
[HTC Sensation] undercover:
Hmmm, I have a feeling that usb causes same thing. Do you have any other chargers available? Using Desire charger works best for me.

Ok, now some food for thoughts.

With supplied charger charging starts with about 800mAh and very gradually gets lower and lower. With Desire charger it starts the same, and stays high till about 80-90 %. Could that be connected? Someone without problem, could you please monitor your phone and report back? Easiest way is to do it is to download Battery Monitor Widget and enable history, change history to every 60 seconds.
[HTC Sensation] moh0:
Now that you mention it I too stopped charging my phone via usb. I just swap batteries with my wall charger and my phone. The problem did disappear around the time I got the battery. So the usb could possibly be the source of the problem. I'll charge my phone via usb tonight and report back on what happens.

[HTC Sensation] undercover:
Someone WITH the issue. Can you try something for me please. Take back cover off (ignore signal drop) and try replicating issue. Then put cover back on and try again. Results?
[HTC Sensation] graffixnyc:
This is not true(I dont think lol). The sensation has a Super Lcd screen and Sony is the only one who makes the Super LCD screen. I'm not 100% sure on that but I thought I had read that somewhere. I know that was the case with the Mytouch 4g where the lcd screens where made by sony and sharp and the sony screen was the better quality over the sharp, I think someone is just trying to make that into a scare rumor about the sensation.

I have a serial not reported yet HT15NV, but my phone isn't 7 days old yet so I will report back in another 4 days :) I did notice issues with response when I had a screen protector on but we shall see :)

Edit: I stand corrected. Doing the command dmesg I found Panel Type PANEL_ID_PYD_SHARP listed there.. BUT I do not see the same issue with this screen that was going on with the MT4G screen where the sharp would wash out more on an angle. Now I'd like to see it side by side with a Sony one

Maybe you should update the OP to have people to include what manufacturer made the panel. Sony, Or Sharp (If there are in fact two makers this time as well) in terminal emulator run the command dmesg it will output a bunch of stuff.. just look for the line <6>[ 9178.895111] Panel Type = PANEL_ID_PYD_??????
[HTC Sensation] undercover:
Will do, thanks for suggestion.
[HTC Sensation] graffixnyc:
Anytime :)

Also I'd like to report after having my sensation 4 days my touch screen has started to get this issue. I found that sometimes a harder press helps. It seems to happen more when I try to use a light swipe.

I also was on a call today and I was on hold and I had it on speakerphone, When they came to the line I tried taking it off speaker but it was unresponsive. I had to press it SEVERAL times, and pretty hard for it to recognize it and turn the speaker off. I think this is more a OS issue than a defect. I used a touch app "Touch Test" from the market and it was registering everything fine. So it could be something in the sense 3.0 ui, or it could be caused by a common factor we all have and dont know it. It's a little annoying at times... I will wait until there is either an update or a custom rom (if/when we get s-off) before I make a huge fuss over it.

I also lock my phone with a pin lock and I noticed when unlocking it sometimes it wont recognize the first digit which is a 6. I have to press it a little harder for it to register.

Serial HT15NV

No date to be found (unbranded unlocked asian version)

Sharp panel
[HTC Sensation] Wisefire:
I have an HT15ST as well with no issues at all, and today marks having the phone for a week.
[HTC Sensation] JayBachatero:
@graffixnyc I'm having the exact same issues. It's weird though because I can't get it to happen while holding it horizontally but I can get it to reproduce a lot of the time on the lock screen by just pressing the power button on and off. Most of the time it won't register the press. Sometimes if I press in the upper portion or registers it and then I'm able to press the bottom portion.

I was on the phone with tech support and they haven't heard of this issue. They offered to replace the phone but I have to return this one first then they send the other one in. Might just go with that route if the problem persists.
[HTC Sensation] naimmkassim:

So can anyone confirm a Sony Panel type? Just wondering if there really are two different types out there.

I'm looking at this phone right now. Having the MT4G and being one of the first to discover and promote the two different screen types on that device. I'm doing my homework and research before buying this one.
[HTC Sensation] graffixnyc:
Yes, we have confirmed two panel types, but NOTHING as bad as the MT4G issue and no sony this time. It's Sharp and AU (which someone said is acer)

Ok, So I had emailed HTC about a few issues. 1. The dust under the screen, 2. Touch Screen not responding and 3. The death grip. I did say many users were experiencing one or more of these issues and just kinda wanted to give them a heads up. This was the email response back:

"Patrick-

Thank you for contacting HTC in regards to your HTC Sensation 4G with T-mobile. I understand that there are few hardware and features in the phone that are causing some inconveniences. I can understand how these faults can be frustrating.

With the dust being under the screen, this is not something that I have heard of as far as being a known issue. I currently use the Sensation as my personal device and have not experienced the dust under my screen. That is not to say that it is not happening, it is just not something that has been reported. I will take the proper steps to report this so we can start tracking this issue and find a resolution.

With your other issue, the icons and widgets not responding, I have experienced this myself. I have found that when this happens clearing the widget as well as the HTC Sense application fixes the issue. Now, there is an inconvenience that is included with the clearing of the HTC Sense application, and that is that all of your home screen customizations are lost. Any widgets you have added or re arranging of application icons are set back to default. If you would like to try this to see if it works you can access the settings of the phone by tapping Home>menu>settings>applications>manage applications> tap the all tab at the top of the screen, locate HTC Sense, tap on it and select clear data. If you continue to experience these issues a Factory Data Reset would be the next step in our software troubleshooting.

In regards to the death grip and signal loss; Every phone experiences a slight variation in signal strength when the antenna is covered in its entirety by a palm or fingers, however under normal circumstances this does not affect the performance of the phone.

If there are any other questions that I can answer for you, please feel free to reply to this email by following the instructions- below. If you would like you can also call our technical support department at 1-866-449-8358 between 6AM and 1AM EST 7 days a week.

Thank you for Contacting HTC,

Melissa
