Ok, so my touch screen seems to be out on a small spot on the right hand side. being where the o,k,m keys would be on the keyboard, p,l, and backspace work as well as i,j,n. However, the same spot when i rotate sideways, doesnt seem to be having issues (where a,z,x,shift,and ?123 are). The problem arose about a few days into running cm7 rc1.2 mr2. The spot also seems to be present in things outside of the keyboard as well, internet browsing is goofy if i need to press in that area, as well as the lockscreen in that spot, very difficult to rotate to change to sound profile.
I have flashed other roms, stock roms, tried different keyboards off the market, everything i could think of. I just want to avoid having to unroot and return to stock, replacing the phone, and rooting, etc all over again to get back to where i was.
Anyone have any suggestions?
admins, sorry for double post in general section, thought i was here
Same thing happened to me the other day on cm7. A reboot seemed to fix it for now, looks like your issue might actually be hardware related though, looks like you may have to do a warranty replacement
This happens sometimes when typing.. if I finish the word it goes away, and I've heard of it happening to others as well. Yours does indeed sound like hardware though, since it occurs in more places than just typing.

So my HTC Desire Z, running CM7, has recently started acting up. There is a certain spot on my touch screen that, at random times, will act as if it's been touched. In GO SMS PRO, this occasionally lines up with a message, so I can see it press, pause, press, pause, etc. It's really annoying and screws up my usage of the phone. If I turn the screen off and then on again, it'll usually go away for a bit.
I've tried googling this issue but it's a touchy thing to phrase. (hehe, "touchy", I didn't even mean to do that!)
Does anybody know how I can find out what is causing this and/or how to fix it?
tl;dr: touch screen is "pressing" a specific spot at random

Its not rocket science is it bro ......... i figure you already can see the writing on the wall ...... sounds like your digitiser is on its way out. Quite a common issue on HTC's the capacitive touch screens just wear out.
My advice is backup, do a factory reset. see if problem persists, if so maybe try a different ROM (just for the sake of testing) see if problem persists.
If so you know its a hardware fault.
The good news is its really pretty easy to replace a digitiser in a Desire Z, I bought my own Desire Z 2nd hand with a dodgy digitiser (for about half its 2nd hand value) and replaced the digitiser in about 3 hours (that was going very slowly and being very careful)
Here is a link to the disassembly guides i used

Desire Z is one of the easiest phones i have ever worked on HTC obviously designed it to be repairable, almost everything is held by screws. So you don't have to 'unclip' loads of weak plastic crap.
All you need is to take it sloooooooowly and NEVER use much force, better to take an hour to do a job that should take 10mins than to rush or get impatient and break sh*t.
Good luck

Update: So the "pressing" isn't really happening any more, but now there's a dead area that takes up an entire horizontal portion of the screen. I tested it out using a TouchTest app (picture 1) and the cut shows the dead portion. However, I tried it again later, and the dead portion moved up! I'm very confused, haha
Having a problem with ALL keyboards (swift, flext9, stock) when tying to type letters on the bottom row (z,x,c,v,b n,m). When trying to input these letters the phone will input the letters directly above. I've read it can be a software or hardware issue. I have pulled the battery, wiped cache, wiped dalvik cache, and ran a superwipe. I was going to try and clear data for the stock keyboard (htc_ime) but cannot find it under Application-Manage application-All. I also tried looking under Application-Manage application-Running; what I found was Touch Input but no options to clear anything. Where is the htc_ime found?
I also noticed when in the dialer that I cannot input *, 0, #. Instead when I press these keys it will input 7, 8, 9, the keys directly above.
I am slowly beginning to believe this is hardware related, but what is weird is that yesterday after wiping cache/dalvik the keyboard worked normally. However, after some time passed, it reverted back to having issues again.
Is there anything else I can try? Could it be possible that the ribbon for the digitizer is loose rather than the digitizer just failing?
Maybe something you did mest up your Calibration you can check by going to.
"Settings ---> Language&Keyboard ---> Touch Input ---> Text Input ---> Calibration tool."
And see if that fixes your problem.
Seems to be known HTC problem for years and they haven't fixed it.
install a free app called 'Draw' from the Play store. When you open it the screen turns black and then slide your finger around and it will leave a line. This will show you if all areas of the digitizer are working. Press your options button to get the menu.
On mine Evo3d the problem started with it randomly starting to start programs or even make a few calls. I now figure that is from the digitizer acting up and behaving as if there was touches in the problem area which happens to cover the stripe of screen about from 1 to 2cm up from the bottom. 0 to 1cm is ok, then 1 to 2cm is bad, then the rest of the screen is ok. What has happened over time is that section of screen no longer seems to trigger phantom touch behavior but it does not register horizontal movement. On the Draw program vertical lines draw fine, horizontal ones leave nothing. Lines drawn at an angle skip and leave vertical lines across the defective area. Unlocking the phone with the Sense ring became almost impossible and I missed numerous calls. Even now that I switched to the slider unlock it is almost all in the bad zone and I have occasional problems getting the phone unlocked.
References are phone held vertical.
The problem originally happened on the stock rom, rooted. I figured it was a software thing so wiped the phone and took the opportunity to install LeeDroid. The problem still exists.
Using the calibration tool or any of several other suggestions does nothing.
Oddly touching keys works for typing and even SlideIT keyboard works though the line it leaves jumps around like crazy. I can't play some games that require that area of the screen. On programs that allow rotating I can usually get it to work as this moves the problem to a different area.
I really don't like friends with iPhones and other brands laughing at my phone.
I started searching Google and there are a LOT of other complaints going back several years and on numerous models, but no real solution. I am disappointed that the response from HTC seems to be that failures are within what they consider acceptable because the solution seems to be return the phone as it is a hardware failure though they do not admit to it. Some people report having the problem within a week on a phone that they left completely stock to see if it really was a user software thing. Some have had the replacement phones quit within a short time as well which makes you wonder if they even replace the digitizer when they recondition them. The actual complaint probably never makes it to the tech so if it works good for 10 seconds out it goes.
I am not very happy with the 'return it' solution since I have a $25 Zagg protector on the screen I will lose and it takes time to set up a new phone, and from the sounds of things the replacement isn't a guaranteed fix. Finding out that it is a known quality control issue that is still present after numerous years has soured me on HTC. If it was a rare occurrence I could understand but not when I read so many reports.
My last flip phone was indestructible and from Samsung. After all the hassles with crappy charge connectors and keyboard contacts from dust at work on a Motorola flip it was a true pleasure. I intend my next phone will be Samsung.

@mugsaway
when you need to type those keys in the dialer try turning your phone sideways as the dialer should rotate.
I noticed today when i woke up i cannot press the right side of the screen and get any kind of response. It is only about a thumbs with of the right edge but this prevents me from being able to hit send on text messages on the default messaging app and also on go sms as the send buttons are in the same general location. Is my phone just FUBAR or is there some way i can resolve the issue. Have tried power cycling and thats about it. I guess i need to know if this is a software issue or a hardware issue and if there is any way to find out and fix the problem.
I've been having the same issue actually. In the bottom right corner, anyway.
Like when I go to attach a picture to a text message, I have to hit the text box first so the paperclip button is out of the corner. I've also had some trouble unlocking with the camera or touching it from the Navbar, where it's positioned in the bottom right corner. :/

I have similar issues with that when my phone is plugged in. And my acreen often locks up kinda with the last image on the screen being the only thing you see until you reset.

I don't think I've had an image stuck to my screen yet. I have this problem even if it isn't plugged in, which is really strange. Not sure why it's so unresponsive, takes several tries to unlock/select.
And kudos for being in Portland too! :good:
Have either of you found a consistent way around the problem or a way to resolve it? Also are you running the phone in the base state that you bought it in or is it rooted / unlocked?
I just tested my phone, by opening the browser to google.com (mostly white background), all around the edge of the screen. And I can see feedback animations for all my touches around the edge of the screen. So I don't think there is any problem with the touch digitizer, at least on my phone. Phone is still stock, rooted and TWRP.
I have touch animation when I touch the bottom right corner on the lockscreen, but it doesn't always drag/ripple out. Sometimes it acts like I've pulled my finger off so I have to do it again.
Rooted, unlocked, stock.
After touch responsiveness got increasingly worse i contacted AT&T and they are sending me a free replacement since these issues seem to be covered under the one year warranty. Just throwing that out there in case anyone else gets as frustrated with the problem as I have and cant find a permanent fix.
I can confirm that I am having very similar problems... it is getting worse.
I am stock rooted and unlocked.
It is getting harder and harder to press things, fling actions (like scrolling through a list) hardly move a thing.
I just installed a multitouch visualizer and whenever I have 2 fingers on the screen and then go to cross them (start with fingers in opposite corners, move one up and the other down until they pass each other in the middle) it actually loses both fingers and then sometimes only one pops up again on the screen.
Can anybody try an app like this Play Store Link.
I've had similar results with 2 other multitouch testers.
Is it my phone, or everybody's?
----EDIT-----
Figured I would install the Base ROM (7.0>7.3) because either it was a software issue and maybe the ROM would fix it, of it was a hardware issue (I really didn't think it should be acting like that) and I would try to get it replaced.
The Base ROM fixed my issue (for now, fingers crossed).
Now using a multitouch visualizer, the contact points are always seen, even when the fingers cross.
Don't know what caused it, but it was software (at least for me).
----EDIT----
Just plugged in the charger again... now the touchscreen is acting strange again... this phone does strange things when plugged in...
So, this thing drives me crazy...I've tried everything I knew and still nothing solved this problem.
I'm using HTC One. About 10 days ago weird things with touch started to happen. It seems that touch is partly unavailable/unresponsible on touch in one or two small areas. It seems to me like theres an empty place on my touch. Visualy is everything fine. Screen is crystal clear and has no damages or scratches. But I can't slide icons without troubles. Somwhere on 1/4 of screen, touch brakes briefly and I need another try to slide the icon. The same thing happens with status bar on the top of screen - I can slide it until that 1/4 part and it stops there and goes back. If I slide it quick with short move, it works fine, just slide alone over problematic area.
Also, few times I had that problem where screen works things on itself will. Makes pictures, or adds filters on Instagram, or, I don't know, just jumps around for few secons. Then, I lock the screen, then unlock it and usually that calm down the screen.
Also weird thing is that, when I want to send message, I can't reach "send" button in first try. I have to drop down writing sheet, than to touch the letters to put it in writing mode again, and then I can click the "send" button. On the same place where it was previously!
At first, I thought that plastic case or PVC protection is the problem, so I took off the protector from the screen. That solved problem for a bit. Then, I put back screen guard, and problem came back. After I totally rejected screen guard, problem is still here. I've tried to reset phone on factory, but that wasn't helpfull...
I forgot to state that I'm using Android 4.2.2 and this started to happen after that version update. I had no problem before.
So, now I'm here, as I don't know what else to do before I take this beauty to service. I just hope that this happens because of software bugs :crying:
Is there anyone who could help me? Have similar problem or know how to fix this?
In the meantime, I'll just hope that 4.3 will fix it themself... :fingers-crossed:
Hi, i have had my tablet for about 1 week, straight after starting it up i had a fw update which is 17.1.1.A.0.402 which i am assuming is the latest?
anyway i have read a lot about the new fw was supposed to fix the touch issues?
I also have the z1 which i still have and is perfect. ive recently updated to 4.4.2 on that and all my issues are fine on there.
my z2 is acting very strange, if i leave it alone for a while sometimes i will go on it and everything on the screen will be frozen, i can't tap anything, i have to press the power button and then swipe to open it again, it is then fine after that.
also i have noticed, and i think its happening a lot when my tablet is a little angled using the case, the screen will be a bit jittery, where as my z1 is really smooth, and i also sometimes have to really tap icons a few times before they register.
i play clash of clans a lot and its been a bit difficult to play as troops aren't selecting as i am tapping on them.
has anyone got any advice?
I have done a factory reset to see if that would fix any issues from the fw update but its still exactly the same.
Thanks
James

I installed the new firmware yesterday. While I notice an improvement with the touch problem it's still present. Just install an multitouch app (like this one: https://play.google.com/store/apps/details?id=com.easylabs.multitouch), let your finger trail on the screen and it's definitely obvious (the number on the top right should be the number of fingers touching the screen and it's often not). I tried the same thing on my old Iconia A500 and that's the one thing where it's WAY better than the Z2.
I don't experience anything as strange as you do though, it's mostly usable and I hardly notice it with the new firmware.
I did experience something very strange just BEFORE updating with one specific charger and one specific USB cable , the tablet wouldn't register any touch at all while it's was plugged in. As soon as I unplugged it it would work. The cable was fine with another charger and vice versa;
Weirdest of it all:
This happened while I was testing the output current for each combination of cable/charger and this particular couple was the one giving the "best" results; consistently between 1.1A and 1.2A
I can't reproduce this behaviour with the new firmware. All in all, it's usable for me. Biggest bug would be it not charging while playing power consuming games.
I have found mine goes more weird when it goes to sleep and i then wake it up, the screens sensitivity seems to be terrible, i have topress the off button and then start it again then its fine.
it will then mostly stay fine until the screen times out again then the same thing will happen when i wake it.
James: Same with my 521...
Touchscreen response was REAL BAD after updating to .402, then it went better and better day by day; strange phenomenon.
I also occasionally experience some touchscreen "numbness" after waking up the table with a double-tap, sometimes touch sensitivity suddenly becomes quite low just without any reason; touchscreen has problems detecting touches near the screen corners or doesn't react to touches at all. Solution: Switch to standby, and back on.
At the same time, the Android symbols (Back, Home, last apps) again become difficult to hit.
You can test this by slowly swiping your finger up from the lower bezel towards one of the symbols: If the touchscreen is ok, symbols get highlighted right after your finger reaches the lower edge of the symbol. If the touchscreen malfunctions, you need to move your finger up to the center of the symbols to get them highlighted.
So it smells like a software issue.
Touchscreen problems usually occur two to three times a day of normal use; so I regard it as acceptable - but the problem still isn't fully solved.
I would say it's a hardware issue which Sony attempts to counterbalance with software patches.
Just like on the Nexus7 (2013). There sfhub released a touchscreen fix which made the problem bearable for most users (with some experimenting with different versions of the fix, because each device is different).
I wrote a PM to sfhub asking him whether he could disclose how his fix works so that Z2 Tablet users perhaps could apply a similar, variable, tailor-made fix to their individual device.
No response, unfortunately.
Perhaps some of you could send the same request to him, and perhaps then he reacts?
every now and then, after double tap to wake, the tablet is extremely unresponsive.
I also just sleep/wake up again via power button and it's fine after that.
So my but feeling it's a software issue, not hardware issue.

I never had touch problems but after updating to the latest firmware, the tablet is unusable from time to time
what's annoying me is that Sony wont seem to admit that there is an issue, i was talking on their live chat to support and they said that's the first time anyone's mentioned that and isn't on any list of any known issues
Which doesn't fill me with confidence on how quick this may get fixed.
The speed in which is gets fixed may determine if i just send the tablet back to Amazon for a full refund, unfortunately i have bought the Sony case and magnetic charger now as well
I'm just really puzzled what to do, what can i do apart from sent it back if Sony wont even acknowledge they are aware of the problem and will release a fix soon
The only thing is because i have now bought the charger and case, i kinda want to keep it.
It was a direct replacement for my Z1 which i still have, and that is also updated to 4.4.2 now, but that shows no touch issues at all.
What's very interesting and revealing:
When Sony was addressed a few days ago regarding battery problems on Tablet Z and a few phones after the Kitkat update, they immediately reacted!
They readily explained that it is a problem with the Google Play Services running amok and that a fix will come.
But it seems that just because this here is a Sony problem (and not one for which another company can be blamed like in the above one), Sony simply doesn't react at all and obviously orders the service employees to lie and say that they haven't heard at all of a touch problem.
Boooo, Sony, shame on you!

HAHA ! Exactly the same in Germany. Even after talking about that issue with the SAME person three days in a row, I still was told the problem was totally unknown.
Later, I had a more private talk with one of the support guys. He revealed to me there was an order from Sony to tell callers exactly that.
Ah, as I thought.
This is abysmal behavior by Sony, period.
Also on the Sony support forum, none of the official support staff has replied to any of the topics about touch screen issues. It seems they are just completely burying their heads in the sand...
FW .402 didnt fix the touch screen issue. It is noticeably better than any FW from before.
Gosh, the touchscreen keep going back to home when i'm in a middle of fb conversatuion.
I was testing with chromecast +youtube: those swibe action to enlarge or fade out afe 99% imprecise...
Really wondering if I can return the item to amazon to fix this problem...

Are you sure you're not just accidentally touching the home button while typing? That happens to me from time to time, which is a downside of having the navigation buttons centered compared to having them in the corner like on pre-4.4 Android tablets. I actually think Google should add a setting to choose if the navigation buttons on tablets are in the left corner, centered, or in the right corner. Having them centered also makes it awkward to reach these buttons when holding the tablet with two hands.
