Interesting. When I was having the issue I was out of town at my buddies house in Brooklyn. Non grounded outlet was being used for charging... hmmmmm.
[HTC Sensation] crisisinthecity:
If I use the stock charger at my house its fine. Used my stock charger on a non grounded plug in Brooklyn and it was having lock screen lag. I'm the 3rd person with this same scenario... maybe we are on to something?
[HTC Sensation] ant2wan:
Ok. so this has been happening a few days. I used my phone today and sometimes it took up to ten tries to unlock the screen. It was getting really bad. While at work my phone ended up totally discharging (fastboot off) and i tried to turn it back on it didnt. Anywho. i get to my car plug it in to my car charger and turn it on. The problem is totally gone. i havent had an issue with the screen since that time. Lets hope it stays that way.
[HTC Sensation] undercover:
Ok then. Someone with problem, can you try charging from USB please?
[HTC Sensation] smashpunks:
Chargers are wacky. Or something with charging ..

Interesting read. More I think about it, more i get convinced that it's to do with static electricity.
[HTC Sensation] RestInPieces209:
Imo, there is no WiFi problem. If you can't see your screen as good when your hand covers it, is that a problem? If your speaker isn't as loud when its in your pocket, is that a problem? No... I'm no cell phone engineer but I imagine that when you cram this much technology into one device it can get hard to put a WiFi antenna somewhere where it will never be covered. If your WiFi signal drops when its held in landscape, move your hand. That simple. Stop complaining that your phone isn't perfect. Just my 2 cents.
[HTC Sensation] Barff1984:
It happens when playing games in landscape...which...most games play in. So if you're playing online games, it keeps dropping the connection which is highly annoying and isn't supposed to do that. I can see where you're coming from, but it i a real complaint and not just being picky
[HTC Sensation] jrwingate6:
Interesting. I just hope our displays aren't getting hot enough for long term damage but then I think, that can't be the problem if most people are reporting the phone automatically fixing itself. The static electricity makes much more sense since people are reporting the automatic fixes. That would obviously be due to the electricity draining itself or something else cunducting it away.

To the people talking about WiFi problems. Can you please discuss this topic in the many threads covering this issue. This thread is for touchscreen issues. Try to remain on topic so the rest of us don't need to read through problems were not having. Thanks.
[HTC Sensation] ant2wan:
Ok now its the next day. the phone charged overnight. No problem :) So far.
[HTC Sensation] undercover:
Now go back to usual charger and use it full time. See if problem develops and charging it with car charger fixes it again. If that happens and works for other people we know cause and a fix. From there we'd have to find out EXACT cause i.e. static, overcharging, undercharging, voltage fluctuation etc......

Thanks for the feedback. :)
[HTC Sensation] timmiii:
Does anybody have a Sensation that's made in China? This might be a replay of the whole myTouch4g with the batch from China being "higher quality" than the one batch from Taiwan.
[HTC Sensation] smashpunks:
Anyone remember my charger thread where it made my screen wacky and I made a video? Well that charger isn't causing that issue anymore :/ I still didn't use it but for ****s and giggles I checked it and it worked fine with no wacky screen. Lmaoooo

Static electricity for sure..
[HTC Sensation] suprvibes:
HT157V I did have lock issues and no apps or widgets responded on touch, rebooted the phone still the same removed the battery and put it make in, booted the phone and so far its been ok this happened about 7 days ago.
[HTC Sensation] undercover:
New theory guys. I have a feeling that this is caused by using phone when on charge. How and why don't know. When I had my first unit which I returned because of touchscreen issue i played with it when it was on charge. With the second unit I'm pretty sure I always left it alone when charging and no problems so far. Coincidence? Anyone willing to confirm or break that theory?
[HTC Sensation] smashpunks:
Sounds possible. Using it while charging may cause a build up of static electricity...
[HTC Sensation] timmiii:
Could this be something with the software rather than a hardware issue? I mean even though a master reset didn't fix the problem for good it still did fix it for some amount of time. The problem just came back after a certain amount of usage or after something was installed that caused it to go crazy in the first place. I'm not trying to generalize this but there are methods that can be used to check the validity of this theory.

I went back to the T-Mobile store where I purchased my Sensatoin from and spoke to a rep (very patient and extremely helpful), he's fairly certain its a software issue more than hardware issue. However, the rep did try out my phone and he did have an issue unlocking it by moving the ring so he's aware of this issue and will keep an eye open for it if other customers come to the store. He also mentioned that it's not very noticeable and could be passed off as someone just missing the ring instead of an unregistered touch command (most people that aren't like us here on this forum will think that).

Someone in here suggested to download an app that tests the device's sensors such as the screen's ability to respond to touch commands. I've downloaded an app called "Z-Device Test" (not sure if that was the app) and within the app there's an option that will allow you to test the screens functionality such as multi-touch response and pressure measurements. I seem to be getting somewhat normal results as the rep tried the same app and tests on his Galexy4G. This may indicate that its no longer a hardware issue but rather a software issue within HTC Sense 3.0. For it to be a hardware issue it would have to happen all the time and since many people here have stated that it happens out of the blue or once in a while then it wouldn't make sense to be a hardware only issue.

I could be wrong but this is a theory and it would be more helpful to try and figure it out together through this method instead of everyone just coming to this thread and stating their screen doesn't work without any additional information. There has to be a common cause for this and it makes more sense for the software to be buggy rather than the hardware especially when it's an unregistered touch command that only happens 1/20 tries a day.

[HTC Sensation] st1g:
Well i don't have the issue anymore, but i had trouble with the screen even after turning on the screen for a while.

The lock ring issue is significant but not exclusive.

Try unlock, leave the screen on, and try to swipe fast, i bet you not gonna be able to activate the carousel thing.
[HTC Sensation] kwaille:
As I've posted on another thread:

Has anobody tryed multitouch test apps on the market?

That would be interesting to compare behaviours between buggy phone vs non buggy...
[HTC Sensation] chippyuk:
Mine is made in China SH165V and have had the same issue for just over a day now!
[HTC Sensation] undercover:
Have you used phone while on charge?
[HTC Sensation] Gurkburken:
Unresponsive screen seems be happening to phones with various serial numbers and various launchers.

How come it fixes itself when charging through/connecting to USB? Does it fix itself by doing that? Would that indicate something electricity-related?
[HTC Sensation] chippyuk:
Yes and it makes no difference at all, via official charger, usb or 3rd party
[HTC Sensation] chippyuk:
I see no evidence it makes any difference when charging etc...
[HTC Sensation] undercover:
Do you still have a problem? If yes, could you NOT use phone while on charger for the next few days and see if problem goes away.
[HTC Sensation] chippyuk:
I have had it on charge overnight and tried it and same issue. Also this is really not a solution....we should not have this type of issue at all!
[HTC Sensation] timmiii:
This turning out to be a software is the hardware is fully operational as proved by device testing app called "z-deviceTest".
[HTC Sensation] Gurkburken:
Ok,

Perhaps people could test their buggy phones and see what that testprog says when testing fast swipes/flicks? How detailed info does it give? (My phone is on service so I cant)
[HTC Sensation] timmiii:
The app "Z-deviceTest" that I use only checked for multi-touch functionality (see how many touch points the screen will read at a given time anywhere on the screen) and pressure applied to the screen.

My results after performing the pressure test is as follows.

I applied pressure with my index finger on all four corners and middle section of the screen which gave me these results:

Pressure Max:0.3176 Min:0.0824 Mean:0.2182

If the screen were to not function then it would not register these pressure readings at all.
[HTC Sensation] DeezNotes:
I've had the phone for a little under a week and haven't had the touchscreen problem *knocks on wood*

Still in the same setup where I'm not using the stock charger. I haven't even taken it out of the packaging yet. I've used the phone constantly, on and off the charger, and plugged it into a computer to charge twice so far.

I was trying to wait and see if I had this issue before I got rid of my Fascinate, but I like this phone waaay too much and made the switch early.
[HTC Sensation] smashpunks:
Im not using the stock charger either since it cause my screen to go wack when it was plugged in. So far so good on day 5
[HTC Sensation] leftheodo:
I have the device for 3 weeks now. Never had any issues. Tried all the tests stated in OP and everything works flawlessly. This have to be hardware related as not all the devices with the same software version have these issues. Do your self a favor and ask for a replacement. I know how frustrating these issues can be :)
[HTC Sensation] ant2wan:
Ok Charged it last nite till this morning with the regular HTC charger, and its still working perfectly. Something may have changed when it totally discharged(fastboot off) maybe?
[HTC Sensation] mikea3000:
I am having a very annoying problem that I think is related. I have the lock screen issue that is intermittent. My biggest complaint is that after I unlock the phone and say want to type a text or dial a phone number, the right hand side of the touch screen is not responsive for about 3-5 seconds. Very, very disappointing.

Is this common or related?
[HTC Sensation] @sshat:
Unfortunately, I took the time to read all posts...

I'm actually pissed and this is going to be off topic, but hopefully on topic. So, yes this is XDA, and workarounds/fixes are always gonna be tried and tested in many different ways and situations to try to circumvent or erase the problem but why? This time, why should we try to fix the problem? HTC locked down the bootloader for christ's sake. We should be way more pissed than anyone is. Throughout all the posts that I have read here, we are licking HTC's balls. Sure they are going to unlock it, but when? It is unacceptable for an OEM to release a phone with this many issues whatsoever, no matter what percentage of phones are affected. We ARE used to flashing. Most of us probably found this site because our phones were fu**ed up in the first place. Now, we are paying top dollar for these supposedly "super" or "smart" phones and we are ALL getting hosed. To top it off, we're kissing their asses at the same time, whether it be the carrier or the OEM. MOST of the posts have been about how this HTC said that and TMo said that. Who cares? Give us a phone we pay $600 or $249 with a 2 year sentence that works out of the box. AND if its not going to, UNLOCK that bootloader so these guys can make that happen. I fell like I got the double F you on this one (happened another time with the HD2) Such a beautiful device. I am most definitely keeping it. Rant ended. If I've offeneded anyone at all blame it on Mr. Woodford Reserve and not me. Sitting here with my battery pulled, good night.
[HTC Sensation] @sshat:
Woohoo!!!! Battery pull worked!!! My Carousel is spinning........Thank you HTC I will keep the static charge out by pulling my battery every few days....its like I'm running an early unofficial test ROM fantastic
[HTC Sensation] zmfl:
I have to post my question here because I am not allowed to in the appropriate thread (since it's in the developers forum).

My screen stopped working again. The phone is also laggy as hell...

I'm fed up, I wanna flash it with that leaked 1.35.X ROM and see if it starts working properly. People say it helps...

I'm aware that I probably won’t be able to update to the official 1.35.X update (once available), but will I be able to update to a newer version (1.40.X or whatever), OR will I be "forever" forced to flash by downloading ROMs?

It might be a stupid question, but I just want to be certain I'm not about to do something even more stupid...
[HTC Sensation] rugge:
avanced task killer

Hi had all of the obove screen issues with the htc sensation and it started when i installed advanced task killer since i removed it every thing works great again dont no if this is the case for all but worked for me!
[HTC Sensation] timmiii:
In the past few days I found that enabling USB debugging and disabling fast boot while keeping about 150mb of ram free will allow Sense to run properly. For some it might mean having less items sync'd or less apps installed (especially ones that run in the background). Performing a factory reset will do something but I haven't noticed it at all and a battery pull may help you if you feel the system running sluggishly.

On a side note, one app that stood out for me was AIM when it ran I would get lag, but when I shut it off everything was ok. I could even scroll through my homescreen as fast as the Evo3D. I've also noticed that while using Google Maps the entire phone will just slow down to the point where it won't function. Hopefully HTC can patch this ram leak issue up quick or just find a optimize Sense and Android 2.3.
[HTC Sensation] nugzo:
My second phone, after a week is now messed up again. i have hundreds of wallpapers on my sd card, it sucks that everytime i try to scroll through them it opens a picture...thats not a damn swipe! Same problem when scrolling throu contacts.. Also no carousel anymore. This is damn depressing. My original 14 days from walmart are up.. i wonder if the replacement phone gave me additional 14 days on it?
[HTC Sensation] nugzo:
I didnt use the stock charger on either of my sensations and still got the issue.
[HTC Sensation] FilipC:
grease screen?

I had a problem with screen not responding properly after a lengthy Robo Defence session. Cleaned the screen properly and the responsiveness returned. Give that a try.
[HTC Sensation] nugzo:
Yes i did that too. Used alcohol to clean it. It absolutely positively had a residue on it and using the alcohol made it "feel" new again, but did not fix my issues. Thanks for suggestion.
[HTC Sensation] poisike:
Firstly, it is official 1.35 and there is no reason you shouldn't be able to update to any official future update.

I'm using 1.35 from the day it leaked and it's better then 1.28. Speed, responsivness, wifi and charging speed has been improved. Unfortunately it doesn't fix the toutchscreen not responding problem.
[HTC Sensation] zmfl:
Tnx. I'm gonna flash it now.

Lagging annoys me more than the lock screen bug anyway...
[HTC Sensation] undercover:
I think I found solution guys. Do not use original charger. USB, third party chargers, other HTC chargers, will do fine. Let phone drain till it switches off, put it on charge, turn it on. You might have to do it twice but it works for me first time. After that top up if you need but again, with a different charger, not the one which comes with Sensation. If you don't have another charger, just use usb port. The

I know it's not a fix, but it's a solution to a problem.
[HTC Sensation] nugzo:
Dang. My original charger is still in the box. Havent used it at all, ever, and i have the problem. I didnt use the stock charger on my first sensation either. I have so many Bluetooth ear pieces that use that same style charger, i've never even opened the stock chargers.
[HTC Sensation] undercover:
Blimey, this is getting really annoying now. It worked for me..... Did you let phone completely discharge?
[HTC Sensation] nugzo:
I did not, because i havent been using the stock charger. I thought that was the culprit. I have some more batteries that do not have a charge on them, i could install one of them.
[HTC Sensation] zmfl:
Ok... 24h with the new software.

Less lag (still present though), no problems unlocking when the phone is in hand, but still gets stuck when it's flat on the table. Also, swiping works perfectly (I can finally get the carousel effect again).

All in all, less problems. They either fixed something, or this will only last for a couple of days like the original software did...

Also, USB charging changes nothing for me. The only time the unlock ring doesn't get stuck is while the phone is charging.

Once off the charger, there is no unlocking unless the phone is in hand.
[HTC Sensation] pdxrealtor:
trangest thing... this morning I grabbed my phone first thing. It was plugged in so I unplugged it.

I pushed the power button and nothing, it wouldn't turn on. So I took the battery out and put it back in.

Turned it on and that battery was at just about 30%, yet it had been on the charger all night.

So, for some reason my phone turned itself off and would not turn back on AND it did not charge all night while plugged into the charger.

To top it off-- Yesterday my phone all of a sudden had the screen problem. Couldn't type, get carousel working etc...

NOW- it works great!:eek:

:confused::confused:
[HTC Sensation] poisike:
Yes, this is normal behavior for (my) Sensation or at least it was until i updated to 1.35. Now i only have the unlocking problem once a week (mostly on Wednesdays).
[HTC Sensation] nugzo:
Ok My carousel is spinning like mad right now. This phone is super fast..but for how long? I think we are getting close to figuring this out..Maybe? Well this is the first time it has worked since it stopped working. I installed ruu from computer, that alone didnt fix it, done that a few times already. Took my sim card out, took my 32gb sd card out and put the 8gb back in and packed it up and headed to walmart for an exchange. I'll be damned if the associate didnt take it out of the box and it ran like new. no problems at all. Of course they wouldnt exchange it.. A few comments have been made about grounding problems.. Maybe? maybe static electricity? well i removed everything that could be removed and it works now. I'm installing my 32gb and sim card now and i'll report back.
[HTC Sensation] undercover:
Had the same thing with my first unit. Hmmm, has anyone changed their sd card.
[HTC Sensation] nugzo:
Still working good. I wonder if it'll take the same time (5-7 days) before it messes up again.
[HTC Sensation] armoguy94:
On day 7 of my phone and the screen LITERALLY has been bugging out on me for the first time ever today, all throughout the day. Not responsive to touch!
[HTC Sensation] Nivek91:
My unlock screen as well has been unresponsive since today and on this same day I bought the black silicon case from T-mobile. So I was messing around and I did a small test to see if having the case on was the cause of my problems. Low and behold, it was. having the case on my phone made my screen less responsive and laggy, while having no case at all made my screen responsive. Sucks because now I have to use my phone without a case in order for my unlock screen to work properly

Edit: I'll do more tests to see if that was the root of my problems
[HTC Sensation] wideasleep1:
Screen responsive, NOT using the included charger (older Nexus One charger).
[HTC Sensation] undercover:
Try using supplied charger, see if problem develops. I've tried it, problem developed, discharged, charged with Desire charger and problem was gone.
[HTC Sensation] gotzta:
Day 4 with this exchanged phone and I finally experienced the touchscreen/lock screen issue people have been complaining about. This is my 4th phone and none of them had this issue (although they had many others). Funny how it just pops up out of the blue after running flawlessly for days :mad:
[HTC Sensation] maschenazi:
Had my Sensation for 5 days now and I have the touchscreen issue. My serial no begins with SH168Vxxxxxx

Just had a word on chat with HTC support and asked about the screen un-responsive problem. She asked me if I installed any 3-rd party software :)

Olga: It sounds like there may be a bug or a corruption which is usually caused by 3rd party apps, a factory reset is very advisable, in case that doesnt fix your issues you will know its most likely a hardware fault, in which case you may need a replacement phone./

ME: also, another problem I noticed is that if I hold my phone flat in my hand, the wireless and mobile signal quality drops and sometimes wireless signal is lost

ME: I was just reading the Sensation forum at XDA developers and looks like quite a few people are having the problem with the touchscreen and with the wireless

Olga: In regards to the wifi network, it is not the handset itself that is at fault but the 2.3 Gingerbread update - one of the features for it is that if the wifi signal is not strong enough it will not show up on the phone completely or will lose the connection all together.

Olga: In regards to the touch screen, that can be due to several factors one of which any 3rd party app can carry bugs that cause issues in the phone, thats why we recommend to read the reviews before installing.

ME: Is there an OTA update comming soon for HTC Sensation to fix some of the reported issues ?

Olga: Unfortunately not, as the gingerbread was only released such a short time ago.

ME: ok, thanks for your time...

I didn't ask about 1.35.401.1 leaked update...

Funny, isn't it ?!

They just asked me to complete a very short satisfaction survey...
[HTC Sensation] undercover:
It is indeed funny, but nothing unusual. They don't seem to know much at that level of tech support.
