The metal contact might be it...

I noticed if you touch the silver metal contact with your finger as you have the back cover off, the performance of the touchscreen increases. This is what I am talking about.

Here is what I believe to be the problem, correct me if I am wrong. That metal contact is meant to ground the phone and it is not working properly or maybe since most of us use rubber or plastic cases, we block that from happening. Since the static has no where to go it just builds up on the phone, and in turn messing up our touch commands. Capacitive touch screens work because our body is a conductor. The screen is coated with a transparent conductor, so it makes sense that static would mess things up. I forgot who but someone said earlier that they charged the phone on a metallic surface and the problem went away, charged it on wood and the problem came back. I study electrical engineering, but I am still a student and I could be wrong but its a start.....right :)
[HTC Sensation] nugzo:
Is this what you are talking about?
[HTC Sensation] aliensmille76:
tested it yesterday,worked also for me:-)

Removed the cover played for two minutes and it worked like new.

Great, thanks

That's a faster metode than with the safe mode.

But now i don't understand why the safe mode also work.

Touchscreen issue was a software problem for me. After a wipe it was okay

[HTC Sensation] aliensmille76:
It will come back:-)
[HTC Sensation] misiek_to_ja:
Hi guys,

Good to hear that it also works for you ! So we have 4 confirmed cases ! You can thanks my daughter, because if I would not be with her on the playground, let be honest - little bored, I would not discover this :) I think it is definitely related to static electricity, as abrown0809 wrote: "Since the static has no where to go it just builds up on the phone, and in turn messing up our touch commands". By putting the phone in our palm we let it go to our body and then to the ground. It might be related to some silver metal contact, but I think the static could gather on different parts as well and by touching the whole phone you can let all the static electricity go to hell. In my case it is totally repeatable, I did several more tests and I think the time required to play with the touchscreen without the back cover is related to the amount of static electricity you have in your phone. Sometimes it is 5 seconds and sometimes I need to play with it for 2 minutes. But anyway it brings my touchscreen back to normal.

And guys - please remember that people mixed several different reasons in this thread for touchscreen problems. Sometimes it is because of the software (restarting the phone, performing hard reset, loading new ROM helps), but most of us experience the second problem - more hardware related.
[HTC Sensation] marine1312:
Had the same problem with sensation got a replacement bad screen they said
[HTC Sensation] misiek_to_ja:
I don't want to make you sad, but read the entire thread - some people did 3-4 replacements and had the same problem after some time. It seems that HTC didn't find fix for this yet and all phones are vulnerable after some time.
[HTC Sensation] veper:
So basically the proper solution is for HTC to produce new, modified back cover that will deal with static?

[HTC Sensation] Pro Gamer:
I bought this phone a month ago and I don't have any problem with touchscreen.

Mine is India branded and production date is : 5/26/2011
[HTC Sensation] undercover:
Glad to hear that solution worked for more people, let's make it one more confirmed case and it goes in the OP as a main solution with all the credits to the guy who discovered it.

To eliminate the problem, after that we shouldn't use stock charger. I'll add more detail to the OP later. But don't forget ,HTC still keep very quiet about this problem, and haven't admitted to it yet, so please,let them know, email is in the OP.
[HTC Sensation] mattdub1:
hi, i can also confirm that taking the cover off and playing with the screen seems to have improved responsiveness so far for me as well, just figured i would add my experience
[HTC Sensation] abrown0809:
Thanks to misiek_ to_ja's daughter!! LOL. Finally my sensation is the phone I wanted to be. I at one point with all these touch screen problems I was beginning to miss the touch screen on my Samsung vibrant galaxy s. That's pretty bad. Now I'm using a Samsung charger to keep the sensation working good.
[HTC Sensation] animaleyes76:
MSI GT725 with stock aluminium brush finish
[HTC Sensation] undercover:
OP updated.

Now, i'm doing little research on how to find a charger which stops problem reappearing. So far, we know for sure HTC Desire stock charger is one of them. Will supply part no later. Guys who have problem could try to request one for free from HTC, that's the least HTC could so to help us.
[HTC Sensation] guitargod:
I can't believe it! It works!

Had the problems with the touchscreen now for the second time.

I played with the phone for 30 seconds without the back-cover on and then i could feel a minimal electrical impulse in my hand.

Afterwards I was able to do the carusell again! I haven't seen it for about a week.

Very cool and thanks to the guy who found that out!
[HTC Sensation] stuart0001:
Glad to hear there appears to be a consistent solution. Ironically my phone has been ok for the last 3 days and I've been using all sorts of chargers. It just fixed itself overnight whilst on-charge. I'll give the bareback technique a go next time I get the problem again. :)

Any advice on the best places to touch the back to encourage the fix? I saw a post earlier but it wasn't clear to me where I should touch it.
[HTC Sensation] undercover:
Stuart, I'm guessing its that silver pin which makes contact with cover.
[HTC Sensation] abrown0809:
Touching the little silver contact helps.
[HTC Sensation] idavid_:
Another possible fix: taking the battery out. I had these issues twice, so I took out the battery for some seconds and it worked! Both times. Try it if it works for you :D

Swyped from my HTC Sensation
[HTC Sensation] aliensmille76:
Battery out is for the most here not enough:-)
[HTC Sensation] misiek_to_ja:
For me it didn't work as well.
[HTC Sensation] stuart0001:
Battery pull has worked for me if it's left out for approx 8+ hours. Any less and it doesn't usually work.
[HTC Sensation] eliteone:
I think you are exactly right, using the phone with the back off worked for me as well. Then I started thinking...... And I realized my back cover is loose on that side. I can physically push the screen in on the right side, and when I do I feel the screen sink into the cover. Sooooo I'm wondering if the case isn't making proper contact with the silver pad? And on a side note if you look at the inside of the back cover there is a small square that has been left unfinished, probably to let the pad make better contact to ground? So if we were to "bridge" the contacts, theoretically the problem should be gone forever? Just an idea I had :)

Edit: just applied my "ghetto tinfoil fix" my problem usually comes back within a few hours, so if this works I have an idea for a more elegant and permanant fix :)
[HTC Sensation] abrown0809:
I tried tin foil last night, when I put it in I didn't see any immediate difference so my lack of patience caused me to pull it out. I hope the tin foil fix yields some results even if its in the long term.
[HTC Sensation] undercover:
Well, its simple enough, just use something thin to get under silver pin and carefully pull it out a bit. I've done it. Thinking about it now, maybe that's why I don't have the problem anymore. I use Desire charger at all times though. Will charge with stock charger and will try to replicate problem.
[HTC Sensation] eliteone:
Exactly what I was about to do, stock charger here I come :) if the problem doesn't come back then I'm thinking about pulling out the ol saudering iron :)

Building out the silver pad with a dab of sauder or two should fixer up for good and permanent then :)

Edit: pulling the pad out a little sounds a little more warranty friendly though ;) maybe that'll be the route to take.....
[HTC Sensation] abrown0809:
Do you use a case with your sensation?
[HTC Sensation] undercover:
Nope.
[HTC Sensation] abrown0809:
No case could also be why you no longer have the problem. The plastic cases block the static.
[HTC Sensation] undercover:
Never had one, but problem was there. Case is not the case here :)
[HTC Sensation] MadBastard:
i got a replaement for my sensation today ,the phone is dead now .should i use a oem charger or what ?? im a bit confused ..:confused:

i was using before DHD charger, whats looks this same as sensation charger
[HTC Sensation] abrown0809:
True.
[HTC Sensation] eliteone:
I can confirm that with the tinfoil in, I just finished a full charge with the stock power supply and screen is still really sensitive. I can't remember the last time I was able to use the carousel this reliably and easily :) the longest ammount of time I've ever had a good screen since I got the phone. I think its time to try and pry the silver contact out a touch :D
[HTC Sensation] zmfl:
So I put a slice of tinfoil on the silver thingy... I’m gonna play some angry birds while charging and see if it gets messed up. Wish me luck :)
[HTC Sensation] karakalem:
Sorry for the late response i wasn't able to check this forum lately. Mu build number is 1.45.486.1 btw it's been 5days and i still don't have any issues now.
[HTC Sensation] Phateless:
Modify the back cover and not the phone. If you warranty you keep the back cover anyway.
[HTC Sensation] abrown0809:
Be careful you don't pull it out all the way, it looks to be attached on both sides, doesn't seem like something that can be bent. I just put in some aluminum foil. Hopefully this works for me too. I will report back. Right now my phone is responsive enough that my lockscreen issues are gone, but I've lost my carousel. Lets see if it comes back.
[HTC Sensation] joe645733:
I got a new sensation. A week after, it started having the problems...then 2 weeks after that...the problems just disappeared.

And on top of that, I received the 1.45 update last week. The phone is doing great.
[HTC Sensation] eliteone:
Ya on closer inspection it made me to nervous to pry on, so I just put a little solder on the back side of the phone. Where the little unfinished square is, works awsome :D must have spent a least 15 min just playing with the carousel :)
[HTC Sensation] Towle:
The screen issues are software related. My screen was horrible until I flashed a custom Rom. Has been working perfect ever since.
[HTC Sensation] stuart0001:
Software tweaks may lessen the symptoms but the cause is almost certainly hardware. Otherwise the issue wouldn't be so sporadic.
[HTC Sensation] undercover:
Stuart, has the new fix worked for you?
[HTC Sensation] Matbiker:
+1

I spend the same
[HTC Sensation] emzed:
The 100% supplied by misiek_to_ja doesn't work here. So that makes it 99%
[HTC Sensation] stuart0001:
My phone has been working perfectly so haven't had the opportunity to test yet. I've tried forcing the issue by using whilst plugged into a variety of chargers but it stays working :D.
[HTC Sensation] pa3e:
Does anyone of you guys tried my solution of the problem (page 53)?

Try to boot your phone in the safe mode..

This helped me and other 2 devices instantly.
[HTC Sensation] stuart0001:
It worked the 1st time I tried it but when the problem came back the next day it didn't. In that instance an overnight battery pull did the trick.
[HTC Sensation] abrown0809:
Safe mode never helped me nor did flashing a custom rom or upgrading the rom. The only thing that is working for me right now is playing with the phone with the back cover off. Currently testing the aluminum foil trick.
[HTC Sensation] cdeeee:
Removing Cover Doesn't solve problem for me

Curious if anyone has similar problems that have been solved.

In addition to the common problems mentioned: lock ring, unresponsive, miss clicks,

I also have the following problems: bottom main buttons (home, settings, back, search) only work if I swipe an exact spot which is above the actual locations of the buttons. At the same time if I am typing I will hit the space bar for example and it will choose the letters above the space bar. It is almost as if the alignment got screwed up. All of the above methods / fixes improve the sensitivity a bit but don't help the bigger issue with the keys at the bottom.
[HTC Sensation] abrown0809:
I used to have problems with the 4 buttons at the bottom but the fix made them go away. I guess the serverity of the problem varies from phone to phone. How long did you play with the phone while the back cover was off?
[HTC Sensation] cdeeee:
I tried playing with it for about 20 minutes and it didn't seem to get better. In fact after playing with it with the cover off the lock ring problem actually got worse again. My radio also seemed to inexplicably turn off twice (no wifi or mobile signal) requiring a reboot. My phone has to get sent all the way back to Taiwan for replacement so I have been trying to avoid having to return it but it looks unavoidable - I may wait to see if OTA update helps whenever it gets pushed my way.
[HTC Sensation] abrown0809:
I'm sorry that it isn't working for you. And BTW, you lose signal because the back cover contains all the antennas. Did you try touching the little square silver contact?
[HTC Sensation] mikro:
nice, they keep on telling everyone wifi signal loss is normal behavior which only confirms they're damn aware the device has got a problem.
[HTC Sensation] billy_overheat:
HT15SV, no problem yet~ but i've replaced it because of dead pixel. let's see how is the phone gonna be from now.
[HTC Sensation] eleven26:
HT15TT, I've had it for a week now and I have no issues.
[HTC Sensation] undercover:
Bump. Keep info coming lads.
[HTC Sensation] jlevy73:
Someone needs to put all this stuff in a spreadsheet to be analyzed for a pattern. Have you noticed any pattern as of yet?
[HTC Sensation] the-bobcat:
HT15KV, lockscreen touch issue appeared 3 days afterwards.
[HTC Sensation] kochavy:
HT15RV had some problem to unlock the screen, I think disable the GPS is solving this problem.
[HTC Sensation] Mr3G:
HT15TT Issue so far:

1.Unable to unlock with weather lock screen, have swipe at multiple times or lick you finger or wipe it dry.

2.Bottom buttons become unresponsive, only happened <5times.

3.Data cuts out while phone is in sleep mode during tethering(wifi&usb)after about 10-15 mins, have to wake the phone for the 4G icon to reappear.Always seems to happen?

4.Using navigation and having 3.5 jack plugged in aux to play playlist on car radio, randomly makes a call??

Really minor issues compared to what other have been experiencing? The data outage during sleep mode really is the only thing that bothers me.
[HTC Sensation] undercover:
Not yet mate. I think we need software version as well for a bigger picture.
[HTC Sensation] GorillaPimp:
HT162T here - no issues. Performed quick test and no problems at all. Uptime 45 hours.
[HTC Sensation] undercover:
Up time since boot or first start up?
[HTC Sensation] Maedhros:
HTC is REALLY disapointing me...

LOL @ all the trolls who attacked me when I said I was worried about HTC Falling into its WinMob Days...

Looks like "new" HTC Fanboys are finally realizing HTC isnt a perfect company... New Generation of HTC Fan boys were reminding me of APple Fanoys for a moment.
[HTC Sensation] jlevy73:
Isn't everyone running the same software version?
[HTC Sensation] jlevy73:
repost of mine: HT163T

Worked fine for about a week and now running into some touch sensitivity issues. Swypes get registered most of the time but not as reliably as before. And the cool caurosel effect, no matter what I do cannot reproduce it. Even on my pathetic battery inhaling, single core HTC Thunderbolt, touch is instant and can obtain carousel effect with ease.
[HTC Sensation] GorillaPimp:
Since last boot. 10 days and 3rd boot (nofastboot) since first start up.
[HTC Sensation] _kansei_:
Yeah honestly coming from Palm most recently, where I camped in front of a Sprint store for a Pre only to be horribly disappointed with the hardware quality, and then further disappointed by the stagnation of the platform during the HP buyout, I expected that it would definitely be better with HTC.

Then my bootloader was locked (I knew this before purchase of course). Then I couldn't remove the carrier bloatware. Then my touchscreen stopped responding frequently. Then my replacement device has a junky screen.

HTC needs to get their act together.

Too bad the one manufacturer that has reliably excellent hardware only sells one form factor, and with an OS that makes me want to hurt myself.
[HTC Sensation] ashandarey:
hi there

HT15EV and working perfectly 10 days so far ....Just have some gps issues, but dunno is it from my phone or location ...nvm

Screen is Sharp
[HTC Sensation] Bipin saspara:
Have all issues what you mentioned and i have SH163V. bought in Belgium. i didn't had it for two three days but now i have that issues. it lags also. while unlocking if i start pressing pass then it start responding after second or third number.

i have one more issue with mail app. i have set it to download every hour. what is happening is that every hour it start from scratch. resulting each and every time download all attachment again and again every hour. it makes my sd card full. and of course it gives negative effect on battery life.
[HTC Sensation] aNYthing24:
HT164T here. No issues so far, but I've only had the phone for a day and a half.
[HTC Sensation] serialtoon:
I too have an HT15ST with zero issues
[HTC Sensation] nugzo:
Mine had been great for past 3 weeks, hasnt seen a charger, only charged batteries. I plugged it in last night to see if the problem would come back so i could try the new fix. It did come back, and after 20 min of playing with back off it's still there and getting worse. i keep touching the silver pad on the side every few seconds... I'll keep playing but damn i hope this fixes it. So far it has NOT.
[HTC Sensation] eliteone:
This touch screen problem is just so Damn random...... Frustrating as hell :( though the screen didn't get responsive for me until I put the back cover back on after grounding the silver pin. Maybe that will work for you?
[HTC Sensation] nugzo:
Still not working. Been playing with it for 40 minutes with cover off. Guess that is not a 100% fix. My method has worked 100% for me, that is only charging batteries in their stand alone charger, never plugging in unless transferring files.. Dammit this sucks, should have never experimented.. I forgot how much i hate this phone!
[HTC Sensation] undercover:
Right, guess it is not 100%, damn, i thought we finally found it.

Out of interest try to touch sim card metal holder when playing with the phone without back cover....
[HTC Sensation] abrown0809:
I thought we had it too. I guess the best thing to do is a combination of the various fixes and figure out which one works for you. This sucks. I got rid of my Samsung galaxy s vibrant because of its bugginess and its completely broken GPS. Got the sensation thinking this phone will be perfect, GPS on this phone works great, but the touch screen is broken....you just can't win with there devices. My girlfriend got the evo 3d, GPS on that phone is crappy, 3g is pretty much broken, to get good network you have to be on 4g. Is there a perfect device? I no longer think so......sigh..Rant over.
[HTC Sensation] Visensio:
Hi everyone! I have a sensation for a month and this last week is giving me the touch bugs, I have the official 2.3.4 version. The problem I have is that the phone does not detect my fast finger movements, to be carrying the mobile went mad inclòs get to lock the screen and also when I leave it on a surface, whether glass timber. I'm desperate and do not know how to fix it. someone feels the same? thank you very much! excuse my English because I am Spanish.
[HTC Sensation] undercover:
Well, read the OP, there are 4 solutions, one is bound to work.
[HTC Sensation] cdeeee:
Tried touching SIM, grounding pin, etc. nada :(
[HTC Sensation] undercover:
100 pages.... Either we are sad, or this problem is really THAT bad. I know that a few of us posted a lot here, but we couldn't fill up 100 pages.....

AND STILL NO SOLID SOLUTION!!!! that would work for everyone.

That was while actually using the phone, correct?
[HTC Sensation] undercover:
Sorry, somehow quoted myself lol
[HTC Sensation] GabrielSousa:
i never has this problem...

now i have :(
[HTC Sensation] GabrielSousa:
some times on incoming calls the screen stills black, right ?
[HTC Sensation] GabrielSousa:
http://xdaforums.com/showpost.php?p=16952405&postcount=41

after flash this pack, my Touchscreen problem was solve...
[HTC Sensation] eliteone:
No the problem is the sensitivity of the screen for some of us. It can be almost impossible to unlock, type quickly, and if you swipe to fast say to start the carousel the screen doesn't register the swipe.
[HTC Sensation] eliteone:
The zip you linked to is very useful for other issues, like the screen not coming back on after a call. But doesn't help for our specific issue. It seems to be more of a hardware issue for us, as opposed to a custom kernel issue like your link fixes.
[HTC Sensation] Towle:
I don't get why people keep trying to guess what the problem is.. it is definitely software. I bet every one of you with screen lag are using the stock ROM, am I right? I always had the screen lag, until I installed a custom Rom, then it instantly went away. I have restored the stock ROM twice, and both times the screen started acting up right away. Installed a custom Rom again, and It's gone!

Don't know how much more proof you need.. stock Rom= screen lag.. custom Rom= no lag... Just make sure you ONLY use the stock kernel with all custom roms as it is the only kernel that can use dual core properly.
[HTC Sensation] abrown0809:
I am afraid you are incorrect my good man, this is a hardware issue. I've flashed many custom roms and the issue never went away. I am currently on insert coin, Ive been on LeeDroid, Android revolution, stock TMOUS Rom, new stock TMOUS ota 1.45.531.1(which some users claimed it fixed problems, didn't fix mine). None of these roms fixed my problems. Only the hardware solutions posted here helped.
[HTC Sensation] Towle:
Weird, I guess I received the only Sensation with a software related screen issue.

Try flashing the stock kernel after flashing a custom ROM then report back. Have never had screen lag since, until I went back to stock to update to 2.3.4 then it went away again right after flashing eagles Blood with the stock kernel.
[HTC Sensation] GabrielSousa:
is strange to be hardware problem, because i never had this problem,

until now, than i flash that zip file, and problem solve...
[HTC Sensation] nugzo:
Thanks but no thanks guys. This is page 100, not page 3. Read some of it. I've had 6 sensations with this problem, last 2 had custom roms and kernels. For me the ONLY way ive found to have the perfect phone is to not charge it at all. Only charge batteries and replace when dead. Has worked great. Definitely NOT a software issue. If it was, a factory reset would fix it. The OP has been on top of this thread since day 1, one of the most thorough around. Thanks man for the hard work. I bet the people who never have problems all have something in common... I bet a lot of them charge the phone in 1 or 2 places all of the time. Maybe they have a metal shelf it's sitting on or something. Maybe some people have better grounding throughout their home or something.... Hell i dont know... I do know it SUCKS!
[HTC Sensation] kris.sh:
Actually I was going to ask if anyone else is having this issue? My back cover is certainly loose.
[HTC Sensation] umd:
Did you install full 1.45 RUU? Because with custom roms you miss some chipset updates.

Also some people reported that installing 1.45 RUU solved battery drain issue too.
[HTC Sensation] kefflar:
I have 1.45 on my HTC Sensation. It is possible to flash RUU once again? My touchscreen issue doesn't gone after I try all three solution.
