I have been having issues with my Droid 2 Global with the touch screen. From time to time it will go crazy and start typing or opening up apps. Sometimes it will open the apps around the lower part of the screen and other times it is an up and down motion that continues untill I lock the screen. Locking the screen will fix it sometimes others I have to pull the battery. I have had this issue with several Roms. I ran 2 different RCs of Venus and now I am running CM9. If anyone else has heard of this or knows something I can try please share the info. Thanks.
Yes, I had a very similar issue. My phone would detect screen presses around the bottom, usually near the unlock slider. It would actually cause my phone to open up my email and delete things on its' own. My only temporary fix was to lock the screen, try to wipe it off, and then unlock it again.
It's a hardware issue with the glass/digitizer, not a software issue. I fixed it by buying a replacement screen on eBay, and haven't had any problems since. If you do replace it yourself, make sure to do it in a clean environment with no dust, and save the tape that covers the speaker, or else dirt and dust will get inside the phone and make the screen look dirty.
Got my US TF700T couple of days ago. It seems that every few minutes or so it sporadically detects touch in the lower right corner.
It's not exactly the same spot - sometimes it's lower and opens notification bar, sometimes it's higher and usually results either on opening shortcut that is their or clicking on the link in browser. I could not find anything that would cause it.
It seems that someone else reported similar problem in Amazon review.
So does it sound like a defect that requires a return? Does anyone else have the same problem?

I've read about something like that on the tf300t forum if my memory doesn't trick me and that user used a multitouch testing app to caught the issue on video. If a factory restore doesn't solve the issue i would say that asking for a replacement unit is the best way.

i haven't had any "unintended touches" problems on the tablet* but i do sometimes have problems where in that lower right corner it's very hard to get it to register a touch. this seems to be a software problem thoug - as it comes and goes and a cold boot always fixes it (warm boot usually does). i'm hoping when i jump from 21 to 26 (or whatever it is when i have time to do it - auto-update not working, even after CM and DM cold-boot and process kills) it'll "go away".
IMPORTANT: if you experiment with touch sensitivity by bringing your finger close to the screen slowly you'll figure out how damn sensitive it is when you're even still a ways away from touching the glass. it MAY be the fact that your right thumb is creating those unintended sporadic touches. FYI/FWIW/YMMV.

* the touchpad on the dock/keyboard is HUGE prone to phantom touches - especially from my left thumb. i finally had to turn the touchpad off so i could use the keyboard!

I just upgraded to 26. It seems lot better. Watched a video for an hour and not a single sporadic touch. I actually enabled developer option to show screen touches. I don't see any excessive sensitivity. My issue was purely random and not related to fingers position. I will continue testing with 26 for few days to decide whether it worth keeping the tablet.
Hi, has anyone else had the center of their touchscreen stop responding? It has been intermittently happening for a couple of days, and I can't seem to pin it to anything I am doing or anything I have changed.
I attached a screen shot of the screen while scribbling in SketchBook to show how the center third of the screen is being skipped. To click anything in the center of the screen, I have to use the track pad on the keyboard.. Powering off and back on clears the issue, but it has come back several times. I hope this is not a hardware issue, what do you think?
Thanks!
BTW - This only happens while using the keyboard dock.
yeah when you close the tab, the keyboard holder presses on the screen too hard and creates a "ghost touch". On//off screen fixes it. as the hinge gets more loose it goes away. i went to developer setings and enabled visual feedback so could spot it.
It seems like when I pinch the rails together to reduce the slop and wiggle of the keyboard and tablet, the ghost spots stop for a few days. I got an AR Drone at Christmas and get nervous about flying it and losing control of the screen (crash and burn).
The main issue I'm having is, on occasion, the touch screen seems to behave erratically, registering input even when I am not touching the screen. I can't seem to figure out how to reproduce it reliably, but it seems to happen at least once every day. The phone seems to think something is touching parts of the screen, as it launches apps, types garbage on the keyboard, bounces the lock screen up and down, etc, all without me even touching the device. And of course, when I do touch the device, it either doesn't register, or 'fights' with the ghost input, and basically doesn't do what I want.
Try changing your touch sensitivity from High to Normal. Find under Settings - touch - Touch sensitivity.
This worked for me Mine was very sensitive too when I first bought it but after messing around with it for a couple of days and changing the setting from High to Normal and back again it's been fine ever since, Crazy!
I first noticed this on a running game where you have to hold down either the left or right side of the screen to move in that direction. It would usually register the first press, but not that I had held my finger down so I wasnt moving properly. I thought this was due to the game it's self rather than my phone.
I've just downloaded Naugh where you have to rotate the screen by touching either side of the phone, and again the same issue. It's really unresponsive - It will recognise the tap but not that i've held it, it will stop working. Occasionaly this will also happen when scrolling a page.
Has anyone else experienced this? Or if not, any suggestions on figuring out whats wrong?

When you go to Settings>About phone - there is a Diagnostics section>Test device. You will see a list of tests you could do including touch screen.
I've tried this, thanks.
There is no aparrent issue using this diagnostic. It doesnt detect multi-touch though, which I find a little odd.
I did find this article though:
http://johnhaller.com/blog/2014-03-06--sony-xperia-z1-z1s-touch-screen-issue
Which seems to be the exact same issue I have on my Z3 now.

What do you mean? There are two options; one which shows dots where you are touching, and another which shows two lines for each point you touch; the lines cross at the point you are touching. They absolutely do detect multitouch, so if you're using more than 1 finger but only seeing one point, or one pair of lines, then you have a problem.
I only have one option under that test, which is to see a yelow line. It doesnt detect more than one touch at a time though.
I have downloaded a seperate screen testing app, and that detects up to ten points at once - again without any obvious issues with unresponsive.
I really can only reliably replicate the issue when playing games.
Mine does have a similarish issue.
Double tap doesn't work on first try when you last use the phone for some time.
But i think it is a software thing cause it worked fine when in continuous use.

In Settings, enable the Developer Options, then tick "show touches" and "pointer location".
I notice this issue all of the time in Ingress, however I have tried multi touch test apps and can easily get perfect tracking with 5 fingers on the screen, so I am sure the multitouch and display is working fine, and I have no problems with Google Maps or Waze where similar gestures to tap on things, and two fingers to rotate and shrink/enlarge are used.
I have no idea what is causing it, but it seems to be software rather than hardware.

I don't play games on the phone, but did try Modern Combat 3/4, which I have purchased long time ago, just to try them out. So I have played last night and have not had touch screen issues.
Yes I have noticed it, and it has at times been extremely frustrating, and 99% of the time I think part of my fingers holding the phone are touching the screen somewhere, each time I see this and adjust my grip the problem is not longer there. I think this also is partly related to the thread about ghost touches.

Yes exactly the same issue.
I agree I think it's software. Another strange thing is If I flip the phone around (So the headphone jack is now on the right, rather the left), and the game allows the screen to rotate, the issue goes away completely.
Such a strange bug.
Same thing here, and it happens very often. I ran all tests and it seems a software issue. Hope Sony solves it 'coz it's damn annoying.
Just discovered something else, in Ingress, it's always been dodgy with multitouch, however if I put the phone on the table or sofa and just touch the screen it's even worse.
Again using the same gestures in Google Maps it works fine.
I don't understand why not holding the phone would make a difference. I tried propping it up on the table to see if it was related to the angle, but still a lot worse when not holding it compared to holding it.
Never had it during games but during calls it kinda doesn't respond to touches properly.....weird.
I am facing too many issues with the Z3. First the camera quality, then the front bezel leaking light, then the 3G, now touch response. Duh!!! Should've bought the HTC M8 EYE.
No such issue for me so far at least.
Isn't the M8 Eye for China only?
I can't type for **** on my Z3 compared to my SIII. Taps don't register as quickly. Not sure what the heck is going on.
I can confirm that the latest firmware 23.0.1.A.5.73 released by Sony today, has fixed my issues with the responsiveness with the screen and games.
I hope I see that update soon. I can't wait to type quickly and double tap with no issues.
No issue with games but, typing is a chore, it keeps pressing the wrong keys like b for spacebar etc....

I've been noticing this lately as well when using the phone when it's on a flat surface.
Sometimes pulling the notification bar down can take a few times.
While play Ruzzle, it's nearly impossible to spell a word unless you pick the phone up.
Was thinking it might be the way it detects your finger, as I normally use the tip of my finger when it's flat, and my thumb when it's in my hand.
