Lock screen....the lock will not move to unlock all the time...and it will not let me click over to answer a different call....
[HTC Sensation] mysterioustko:
How about we try to stay away from the generalizations.... I DO NOT have any touchscreen issues, and I came from a G2X...and it doesn't get any faster than a G2X.
[HTC Sensation] poisike:
Same here, i had this issue on days 5 and 6, then it just disappeared. I didn't change any settings and i didn't install/uninstall any apps (that i could remember). Only thing that changed, i drove to summer home on day 5 and it was very high humidity in house when i arrived...

Poll needs another option: Yes, but it fixed itself.
[HTC Sensation] bendotson:
I had this problem with my launch-day evo 4g. If you had it on a table where the phone wasnt grounded, the bottom half of the screen would not respond. This was really evident with a drawing app. I dont have time to experiment with my pone today but maybe someone else can try that.
[HTC Sensation] umd:
Here is a video about that. Post here if you unlock the phone only you hold the ring from its left side like on the video.

[HTC Sensation] skr_xd:
Actually i had problems with 2 devices i bought from a ebay seller which are singapore versions (SEA) and 2 from Expansys USA. Out of those one from expansys is what iam using now. I have sold the other three.

May be the problem is not for all devices then like what i thought with my experience. May be some batches???:confused:
[HTC Sensation] tigerz0202:
no issues here everything works perfect ,actually almost too sensitive
[HTC Sensation] mysterioustko:
....oh boy......here we go again.....the same thing was said about the nexus one....people constantly whined about it having a "grounding issue"...then an update was released and the "issue" people had with "grounding" was gone......

There is no "grounding issue" with the phone. Simple as that.
[HTC Sensation] brian6685:
I had a bunch of.touchscreen issues with my sensation. I finally got frustrated and did a factory reset and its been 5 days and haven't had an issue yet. That seemed to have cleared everything up for me
[HTC Sensation] leftheodo:
I had a DHD before getting my sensation. I have never had touch screen issues and i don't see any difference in screen responsiveness from my dhd. So SPEAK FOR YOUR SELF:mad:
[HTC Sensation] jlevy73:
Hmm, interesting video thanks for posting that.
[HTC Sensation] Maedhros:
Why are ppl getting so defensive about having/not having the issue?

Once again... ppl defending the Sensation like no tommorow... srsly...

The issue might be like with the HTC Magic.

When you charge you would get weird touch screen issues...
[HTC Sensation] skr_xd:
I have taken back my words of generalization already friend:D

Check my previous reply also in this thread;)

O.k. Editing my first post also to make it smooth and go with actual topic of the thread.

Half the issue is the charger... http://xdaforums.com/showthread.php?p=15082611#post15082611
[HTC Sensation] wadill:
I have a sharp screen and after the first few days I had the touchscreen issue. It did go away and now I have no problems at all. My screen works fine when on the charger. Only thing is when it's laying flat on a table it is unresponsive, obviously a grounding issue. But I never use it just laying flat, so really it fixed itself.
[HTC Sensation] GoRRaN:
I had the same issue, and it fixed it by it selfs
[HTC Sensation] atlman28:
My lock screen was not responding. I bought my sensation on Tuesday. The build date for that phone was 06/02/2011. Took it back to T-mobile today and got a new one. I told the guy not to bring out a phone that was before the date on the first phone and that i would not accept it if it was. The build date for this phone is 06/03/2011. I have not had the issue yet and told the guy at the store that I will be back for a new phone if it started again.
[HTC Sensation] pdxrealtor:
It's not just the fact the phone is charging, its the fact that when the phone is charging it heats up.

Try using the phone with a system intensive app, something that will heat up the phone, and you'll see the same issue.
[HTC Sensation] jrwingate6:
Why doesn't it happen when I'm using a different charger? Also, I have gotten my phone pretty hot while playing Homerun Battle 3D and not once did the screen become unresponsive. Mine also started doing this first thing in the morning while the device wasn't even warm yet. I don't think being hot has anything to do with it.
[HTC Sensation] Profondo_Rosso:
If you read the thread fully, you'll see a massive generalization on page 2 about MOST people having the issue, and that they come from a slower device so they don't notice it.

Hence people like myself calling that BS, since I came from a G2X.

Not saying nobody has it, but I do not believe MOST have it either. Is that defending the phone, or defending against a generalization?
[HTC Sensation] timmiii:
I too have been having an issue with my touch screen however it's a when I unlock the phone from standby mode. However, I was able to solve this by calibrating the G sensor. I'm running the Auo_NT screen and fast swipes are ok.
[HTC Sensation] crisisinthecity:
I did have some issues a few days in with the lock screen but it happened after I installed hopstop. I removed it then reinstalled it and everything is ok. Its fine now and works fine on the stock charger. Sharp screen, 6/2 manufacture date, HT16 serial number. I love this phone.
[HTC Sensation] n8dwgphx:
Locked up using camera 7 hours after purchase.

Mine locked up using the camera after the sun went down here in phx, az. I went to two different pools parties that day but phone was never in the sun or around the water. The screen was unresponsive and so were the touch buttons at the bottom. I think pressing the on/off at the top got it going again but I'm not sure what corrected it.
[HTC Sensation] thisguy10:
I have a touch screen issue when i open the tweetcaster app. i cant swipe left or right, up or down till about 20 secs later. its like the phone freezes but its not, i can still press apps and the home button but thats it.
[HTC Sensation] howetechnical:
Can't say that I've noticed any sort of lag on the responsiveness of the screen at all, but then again, I haven't had any of the issues reported here aside from the death grip on WiFi signal. I've had my Sensation plugged in while playing games, got it real hot, and still the screen was very responsive.

It doesn't matter how slow of a phone you came from, unresponsiveness is unresponsiveness. If it takes an extra second to register that you've touched it, you'll notice that, even if you came from a flip phone.
[HTC Sensation] swiftinmotion:
All i seem to come across is the screen issue when trying to read up on this phone..

I have not noticed anything different with this phone other then it heating up when playing plants vs zombies..

going on 3rd day with this phone and its been a charm.. but will keep an eye out
[HTC Sensation] heygrl:
It was happening but now it's not. With how wonky it can be (pulling the notifications panel down can reactivate it) I'd say it's a software bug. If it isn't HTC will gladly replace the phone.
[HTC Sensation] CasperT1:
Me to I also remove the screen protector thinking that was the problem but it was the same must of the problems it's to unlock, I don't have the screen protector any more but I did factory reset and some times I still have the problem.... Now I hate the ring
[HTC Sensation] Matteo_KSA:
I never had problems with mine until yesterday, just like others already reported it happens with some screen locks, specially the weather one! And it happends when meteo data are not available. With the clock lockscreen or the default one no issues at all.
[HTC Sensation] cjm1979:
I only started to get this yesterday after around 3 weeks. Its mainly the capacitive back key.
[HTC Sensation] Castle5665:
No screen issues at all for me. Screen has been fast and responsive on swipes.

The only thing that has not worked to my satisfaction is the htc music player. Album art and song lists are all wrong with many FCs. Other music players work just fine. Using PowerAMP.
[HTC Sensation] lilcleo001:
heptic feedback

I'm on my second S4G. My first one, the screen seemed loose when I pressed the bottom right corner. Ran smoothly.

On my new S4G, the heptic feedback turns on and off. I would be typing on the keyboard and it only works sometimes. I just rebooted and now I can't press any of the icons on the screen. only the menu, phone, drop menu, etc. I can click and hold on a app, and it will display if I want to remove it. But I can not click and open an app on the desktop.
[HTC Sensation] MikeMcD:
Had mine for about a week I think. No issues to this point. Screen works great holding it, on the table - either way.
[HTC Sensation] lysergic:
Had the phone for almost 1 wk and today I experienced the screen issue :(

To me it looks like a weird software glitch. It can easily become annoying... :mad:
[HTC Sensation] PrisonerOfDoom:
Picked up my phone at launch (June 15th) and it has been absolutely perfect until today. The lock ring has become almost completely unresponsive. I have to try multiple times to unlock my phone or use one of the shortcuts. Also, I am having the same problem with not being able to answer or end calls. I have to keep pressing the screen until it decides to work. I have done a battery pull, etc and it still happens. I took it to the store where I bought it from and they haven't seen this problem yet. They recommend I swap it out which I will be doing tomorrow. Hopefully it doesn't happen with the new phone.
[HTC Sensation] aNYthing24:
I'm beginning to have touch screen/lock screen issues. I had to do a battery pull today because the lock screen was half black and I couldn't pull the ring up and then I couldn't swipe or click on anything later on so I did a soft reset. I hope this doesn't happen again.
[HTC Sensation] jasonm253:
had mine for a week as well. i exchanged mine and should get a new one in a couple days. come to realize it probably doesn't matter.

Best work around is download the widget locker.
[HTC Sensation] howetechnical:
Have had the S4G since Thursday, just now had my first issue. Got hot after playing some games, then random stuff wouldn't even register a touch. Hard reboot fixed it for now.
[HTC Sensation] Tweezydak1d:
im on my second sensation and and they both started messing when the second week of having it approached
[HTC Sensation] SoFaKiNgStOkeD:
Having both the unlock issue (I have to swipe it 5-6 times before it unlocks) and now I'm having random touch screen issues even on the home and back buttons on the bottom. It looks like I might be shopping for another phone if root access doesn't hurry up! I hate Sense 3.0 too.
[HTC Sensation] aNYthing24:
Sorta unrelated, but does anyone's screen move down a bit when they press on it on the left side?
[HTC Sensation] ashandarey:
yeah mine, on the right side (where is search button)
[HTC Sensation] C0NAN:
I suddenly experienced this after I put took off and put back the rear cover. I took it out again, re-seated the battery and back cover and then it went back to normal again.
[HTC Sensation] ashandarey:
I'm took off back cover ....few times and nothings change ...same moving down on screen ...on the side of a search button
[HTC Sensation] mmeyer4663:
I am also having the issue with the lock ring.

Here is one thing I have just tried.

I installed the free "No Lock" app from the market and used that to disable the lock.

When I press the power button to come out of stby, it takes several seconds before my touch screen is usable.

Maybe the problem we are seeing with the lock ring is related to the device "waking up" from stby more that the functionality of the lock ring itself.

Anyone with the screen issue able to confirm they are seeing similar behavior?
[HTC Sensation] Dolphinwigs:
turn off fast boot. then reboot. if that doesnt solve it try also turning off power efficiency as well. these seemed to cause a lot of my connection/lag/screen issues. at least they went away after. though connection is still not perfect, just better. test at let me know if it works for you
[HTC Sensation] timmiii:
I see what you mean, after a restart then locking my phone will replicate this issue. My phone is getting confused on the first initial swipe by thinking my finger is higher up and trying to touch the quick launch apps instead of the ring. If I hold on to the ring for a second or two then swipe it to unlock it'll work or if i grab it from the left side and swipe up towards the left. This is definitely sounding more like a software glitch in Sense 3.0.

I have installed the app but after standby my phone's screen is usable almost immediately after unlocking.
[HTC Sensation] kwaille:
Has anobody tryed multitouch test apps on the market?

That would be interesting to compare behaviours between buggy phone vs non buggy...
[HTC Sensation] smashpunks:
I did. I had no issues and mt test worked fine. Then when my phone wigged I tried it and it was crazy...
[HTC Sensation] jerrylzy:
I have never heard anyone who is in china has this issue..
[HTC Sensation] timmiii:
The testing app showed that the screen was working. It passed the multi-touch test and the pressure tests. However, when using the phone its just going down the poo poo shoot atm. I missed a call, couldn't unlock the phone until after a few tries and just doing anything requires more than one touch.

Just curious but I have the following software info:

Kernel Version

2.6.35.10-gb7a86da

Baseband Version

10.42.9007.00P_10.11.9007.15_M

Build Number

1.29.531.2 CL70849 release-keys

I wonder if other people whom are having the same touchscreen issues are running the same software while the ones that are reporting no issues running a different build version?
[HTC Sensation] johnsmith970:
I had a mytouch 4g with screen lag and unresponsiveness. It turned out that /init was hogging 100% of the CPU. Turning on USB debugging fixed the issue for me. Not saying that's the issue here but it's worth a shot if it's a bug in sense.
[HTC Sensation] smashpunks:
No, I have that version and have no touch screen issues. Only the lock screen issue once in a while but I think that's a software bug.

Now I did have issues, done away with the stock charger and the issue went away...
[HTC Sensation] timmiii:
I tried it out last night and my phone seems to respond slightly better.
[HTC Sensation] timmiii:
If you had the lock screen issue while running this particular software then it does mean the software itself has a bug. Using third party chargers or stock the stock charger will make no difference at least for my device. It could just be a coincidence that it temporarily solved your issue.
[HTC Sensation] jonathan3579:
I am experiencing it right now actually. This is definitely software related as I can pull the notification bar down, swipe the screens and select the launcher. However, I cannot select any apps on my homescreen. I'm fully aware that restarting the phone will remedy it. I thought now was finally a good time to comment on the issue. Lol
[HTC Sensation] smashpunks:
Naaa, I may have the lockscreen software bug, but thats different from the Touch screen/charger issue. http://www.youtube.com/watch?v=aOp0_tiTHJg

heres my bug... its gone now I dont use that charger.

IMO the lockscreen bug is different, I think that issue has something to do with the software they use to get the ring and the app icon to move at the same time. You know how its kinda like you move the app to the ring and the ring draws to the app until you center it in the ring? I think theres a bug in that movement cause the lock screen bug.

but the screen issue is totally different IMO.
[HTC Sensation] mmeyer4663:
Well. This is bizarre.

This morning, just as mysteriously as the lock ring problem happened, I am no longer having any problems with the lock ring to unlock. I changed nothing on the phone between last night when I still had the problem and this morning.

Weird!
[HTC Sensation] zmfl:
Got the issue after a week. The phone wouldn't unlock on the first attempt and fast swipes weren't working. Getting the carousel to spin was impossible.

It also started lagging in menus and home screens, which is retarded if you consider what hardware it has in it. (This and the fast swipes issue could be connected?)

I believe unfinished Sense 3.0 is to blame... There are leaked ROMs that supposedly fix some of the issues. Can anybody confirm this?

Oh, also, my phone is working now. No bloody reason for it. It just is.

Is it grounding? Static electricity? Wrong cables/chargers? Humidity? Heat? Moon phase?
[HTC Sensation] Rick Chase:
Started having issues yesterday but did a battery pull with the phone on and it smoothed out.
[HTC Sensation] jasonm253:
sucks cause my new one is coming in the morning and my touch screen issues have stopped. So it seems like it has nothing to do with the phones.
[HTC Sensation] AGunz82:
Seems that the weather lockscreen does cause most of the unlock issues....

Scratch that, issue still occurs. This is my second Sensation so I'm starting to believe it's a software issue....

Okay now, I have began using the wallpaper only lockscreen for a day and the issue has disappeared.
[HTC Sensation] mikea3000:
I am having a very annoying problem that I think may be related to the lock screen issues. 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] shooric:
Same issue as described, the annoying lockscreen issue + random no-response from bottom of the screen. Here is the video that shows the lockscreen issue.

[YOUTUBE]NbIrdQ3ejDI[/YOUTUBE]

Resetting the phone or running the calibration does not seem to help :(
[HTC Sensation] BBOOZE:
I know I've seen this mentioned somewhere but my only lock screen issues happen when I have the phone lying down on a table. Completely unresponsive then. But if I pick it up in my hand works fine.
[HTC Sensation] smashpunks:
Ok so somehowmy WiFi signal is getting better wtf? Where before I could kill it easy, I can't do.that anymore, like it fixed itself..... I can kill it trying but now I can hold it.fine without dying. Really strange.
[HTC Sensation] shooric:
lucky you :) mine has the issue even if I hold it a-la "iphone 4 grip" :)
[HTC Sensation] MarlinFF:
I'm just starting to get the lockscreen issues as well. Tried resetting/pulling battery and neither has worked. I have like 2 weeks left to return/exchange it so I'll be going to a store to do that if it persists for the next two weeks. Otherwise the phone is great.. Sigh
[HTC Sensation] jrwingate6:
Yea, there are some serious memory leaks going on with some of the bloatware installed. We need Root like NOW. HTC, either update Sense or unlock the bootloader.
[HTC Sensation] BonesRed:
We have temp root so get crackin'
[HTC Sensation] Bsketball:
So, I have the problem with the unresponsive touch sceen, as well as a bad wifi death grip issue.

I just tried my brother's sensation, and there is no such touch screen problem. It works perfectly in fact. I tried a factory reset and my issue still exists, so I'm going to swap my phone out and hope I get one that works perfectly.
[HTC Sensation] timmiii:
Whats the build and/or ship date of your device and your brother's.
[HTC Sensation] fallenangel408:
old/new

my old one had touch response issues, esp when laying on table trying to unlock, never got the courasel to work(like it mattered but i knew if it didnt do that the touch response was not up to par) my old phone was 5/31/11 ZT15 made in taiwan my new one is 6/6/11 SH15 made in china. day and night diff cant even compare the 2 now im liking this device!!!
[HTC Sensation] nugzo:
Has anybody tried to install the RUU instead of just doing a factory reset? incase a reset isnt actually resetting everything? I'll try now and report back.
[HTC Sensation] smashpunks:
That's what I have wondered.
[HTC Sensation] poisike:
I installed the leaked 1.35 update, worked great for 5 days and then the lockscreen problems returned.
[HTC Sensation] Paging Dr B:
New Theory

My phone was great until a week in. On Friday my screen began acting crazy, hard to unlock, no carousel, etc. Last night I tried the battery pull and that didn't work. I tried just about all of the other suggestions short of a full wipe, then it hit me like a ton of bricks. It's a grounding issue.

I thought about it for a sec, then pulled off my back cover and with a clean cloth I wiped all of the contacts on the case and phone. This phone sits in my pocket most of the week, and it collects a decent amount of lint behind the case. It just somehow made sense to me that this is what could have been causing it. Think about it, most people don't have this problem when they first get the phone, but around a week later it's hitting everyone. Maybe it's a weeks worth of lint that's causing this chaos, which is why a factory reset isn't doing the trick. It also might explain why the battery pull is working for some and not others. When the battery is off, the case is off and maybe the owners are cleaning the lint without knowing.

Sorry for the long post, I was excited and wanted to share that with my peeps. I hope that helps someone. If you're still having the issue try giving it a shot and report back. All I know is that yesterday I was bummed at the thought of replacing it, and today I have one swipe carousels again and everything is back to being uber responsive.
[HTC Sensation] umd:
I'm really interested in fixing this issue. I don't have anything wrong right now so I can't test it but I can confirm that this issue got much worse after I put it in my pocket. I tought it was pressure that caused this. Also I didn't clean it up when I pull the battery. I would like to know if this fix works as well.
[HTC Sensation] nugzo:
Just gave it a try, no luck :( After cleaning didnt help i actually bent out the contacts just a tad so they would make better contact, still busted.. Thanks for the suggestion though.
[HTC Sensation] umd:
Here is my idea.

Since I've replaced my phone I'm using clamp filters on my USB cable. General means it filters "noises" like electromagnetic interference.

This idea came up with my old Sony NW-HD3 music player. It has these clamps on its both USB and charge cables. An important similarity is NW-HD3 has metal body like Sensation.

Its been 3 days and I've charged my phone 3 times. I haven't seen anything that might be relevant this issue.

Also did anyone try short circuit rather than just pulling battery out? Similar to toughts of Paging Dr B, when you were cleaning the contacts up you might have done short circuit the battery with cotton.
