is there anyway to calibrate the screen? im having some calibration issues with my g2x and restarting the phone doesnt help!
I just looked through the hidden menu list. I don't see anything about calibration.
Out of my last three phones that had touch screens, Ascend, Evo, and Indulge, It seems like only one had a calibrate screen option, so I don't think it's real common.
What problems are you having? I've noticed a lot of times with my G2X that when I push a link, it highlights right above it. But the link still works.
I have issues as well, there are no calibration settings in Hidden Menu. Sometimes I press on the screen and it hits something else. Sometimes, I'm not even TOUCHING the phone and it will, by itself, select and enter into different apps on my screen. I thought I had a virus on this thing.
I checked around, other people are having these issues and have NO real fix for it. It has to be an SW problem. When I first started using my G2x, there were no touchscreen problems like there are now. Guess I'm gonna have to change my signature on the G2x away from "so far no issues".

I've noticed that the edge of the screen is very very sensitive. I'm constantly opening droidtv when the app drawer is open. It's right at the bottom left. My fat fingers overlap the edge enough to open it. Makes me laigh.
Also, I've set launcher pro to scroll the apps up and around like it is in the stock drawer. It cracks me up how it is so sensitive that you can open the app while the icon is scrolled up and around the corner. Even when it's two rows back and especially out of the way. Try it.
I know you said you weren't touching the phone, but maybe some of these times were when you were just holding it?
Yeah, when I'm holding the phone, the bottom of my palm near my thumb is close to the edge of the screen, and it registers as if I were pressing on the screen with my other fingers.
The screen jumping around randomly, I can't explain it. And it does happen when I'm not even touching it. I would put the phone down and watch it go, entering menus and apps and pressing all kinds of things. On one of the forums I linked, someone said to remove the battery and let it sit for a few seconds, then put it back in. So I've tried that, and so far the touchscreen isn't acting possessed anymore. This isn't a constant thing. It's just happening at random times on my phone, it's leaving me confused lol.
I've just began to run into this issue. It most apparent when using the keyboard, and switching keyboards doesn't even seem to help.
CM7 fixed the calibration and touchscreen issues long long long ago.
I've got Xperia J with CM 10, release FXP217, kernel version 3.0.8. Everything seems all right and the phone works as it should (except of the known issues and bugs). But I noticed that nobody mentioned, that their touch freezes or anything.
The main issue and reason for asking this question - sometimes my screen, or rather touch, freezes and there's nothing I can do with it. It doesn't react to any movement, but the phone itself remains functional and does everything normally, so it doesn't remain active or anything, just doesn't react to any touch at all. I have to press power button a lot before it starts reacting again. I usually press the power button and move my finger across the screen for as long as it doesn't lock itself or unfreeze.
At other occasions it does something a bit different - the touch gets a bit dull and unresponsive in general, but after some using it, it goes back to normal. When using the Pointer location overlay i noticed, that while I move my finger across the screen, the trail stops for a half a second or so and continues. It's like the touch periodically gets "disabled" or something. But when I press HARD and move my finger a bit slower than regularly it mostly is good and after some time - it gets back to normal.
One day it may occur twice or maybe even not at all, sometimes it happens a lot, like even 4-7 times; at rare occasions, this problem reoccures in small periods of time (like when I use the touch screen a lot).
Is there anything known about this issue? Is there a fix for that?
I had issues with my Asus TF700t that quite often it did not react on touch gestures.
And on the home screen the "change backround" dialog opened sometimes without any touch on the device.
This happend very very often when it was in the dock, but also without the dock (less occurence).
Now i know that the reason are ghost touches. By the usage of touch test apps (e.g. "Simple Touchscreen Tester" oder "Yet Another MultiTouch Test") i realized the ghost touches.
This touches are recognized always on the same coordinates. The multitouch test app detects 4 fingers on the same y-axis.
When the tab is in the dock and i open it completely to the maximum the two bolts from the dock are pressing very strong to the background of the screen glass. This is causing the ghost touches.
I opened the tab and tried to find what could be wrong (especially on the area where the touches are detected).
Anyhow i could not find anything. The only thing i noticed was the on the y-axis of the ghost touches the screen is fixed on the left and the right.
I check everything else closed the case ... but the ghost touches are still present.
Any idea how to fix the issue??? Who else realized the same issue???
Attached some screen shots from the touch test apps.

Sounds like you have a digitiser hardware issue to me. Had the same on my Surface RT. Only fix was to get it replaced.
Yeah, I just got mine back from warranty digitizer recalibration.
tapatalkin'
Another TF700T here that just returned from RMA with digitizer repair. Went very smoothly for me and I have a TF700T that again works extremely well.
Do they replace parts or just recalibration? Is it possible to so this myself?
I have unlocked bootloader and i do not know if they will repair it without any problem. Any experience on this?
Hi,
First, sorry for my english...
Second, I have same problem since saturday 24 august with my TF700T. Buy november 2012.
I tried to updated to android 4.2 But it didn't solve my pb.
I try "Multi Touch test" app and I observed same problem than mr_cg. Thanks for your good description "Ghost touch"
Ghost disappear when i unplug and re-plug dock, (some time two or three time) but just for some second ...

If you are root, you can perhaps try this app:
ILITEK Touch Utility
or
(less chance i think, it did for S2,S3) TouchScreenTune
Me i am not root, but if it is working for you, perhaps i will try to be.
Thanks for your help

Thanks for the hint. I tried the apps, but both do not solve my issues.
ILITEK ... descriptions sounds good, but unfortunately not working (i get always "access denied" even i have root for sure).
TouchScreenTune ... Based on description it should be also good tool to reduce/improve situation with ghost touches. Anyhow ... it is not working with TF700t.
I am just thinking if i should open the case again???
If with root permissions you don't find solution ... I think i should call Asus support for my first RMA..
snif snif.
Thanks for your return. I win a lot of time.
Same issue
I'm having the same issue here, but only when docked. Seems like I'll stop using the dock since I am out of waranty because I unlocked the bootloader ...:S
I've been having a similar issue very badly on the right side of my screen, it was practically unusable. I am also out of warranty because I'm unlocked. What I did to make it at least somewhat usable was go into the build prop and change my max touch screen events from 200 to 4, and changed my touch sensitivity from .001 to 1 (this setting may have only been available on CROMI. Anyway, now my touchscreen doesn't work on the right side, however it does work everywhere else, and most importantly I can still use the tab as a laptop in its dock. It's a bumm it doesn't work right, but it's better than a total loss!
Sorry guys, it is a failed design problem due to connection to the touch screen. see my post in the "so i took it apart" thread.
Cost me a ruined lcd screen to figure it out

What a great thread! Thanks, I've posted this elsewhere but having just send my TF700 back to ASUS I now have a pretty good idea of what might have been wrong with it. Here's what I posted and what I've told them anyway. I've overlooked the Ghost touches unfortunately, so I will let them know that (if they don't already)......any comments welcome...
Asus Transformer S/N D20KAS016975
I've struggled with this tablet since purchase in April this year, not being at all familiar with tablets I did not know whether it was just me, the general setup, or the tablet itself at fault. Most certainly the performance is not satisfactory. I have done three 'Factory Resets' and numerous Soft Resets.
Intermittently, the tablet will scroll and flash through various apps, when I open it. Originally File Manager would open itself up, then I got the feeling the Weather app would upset things. Sometimes a browser would make it do the same. Then I tried various Launchers, but the best of them (I think) sometimes shows the menu unannounced. Same thing, on and off until I intervene.
It is also prone to do this just sitting open by itself.
Clearing the caches sometimes fixes this. Sometimes this will stop by itself, other times I need to either close the lid, press the lock button, or turn it off. Then it will be OK.
At times Gmail will scroll randomly through the accounts, messages, labels etc.
Every browser I've tried will sometimes shut itself off, especially if I try to type something into a message box, usually when I've spent some time doing this!
Occasionally I can feel a slight tingling sensation when I'm lightly touching the back of the screen.
One other thing: When left overnight the mouse doesn't work and the tablet needs to be turned off and on again for the mouse to work. I also think the screen doesn't turn off sometimes (can see a light).
At other times the whole thing works just fine.
Hope this helps.
Regards
Grant
Tablet arrived back this morning

Tablet arrived back this morning and seems all OK. Report indicates they replaced the LCD panel (new) & replaced the touch controller board (also new). And did various tests. Good service I think, no fuss. I'll let you know how it's going in a few days.

Grant,
Was your tablet still under warranty? Did they charge anything? I wonder if they redesigned the digitizer connection or just put a new screen which will wear out as well. The digitizer connector runs along the bottom left of tablet screen. Same area is being pressed when you close dock, which wears it out.
You can go to developer settings and enable "show touches" (lowers tablet performance) then press on the bottom left edge of the screen, roughly 1/3 point of its length, and see if you get the ghosts to appear.

Yes, still under warranty (problem was there from day 1 although I didn't realise it at the time) and no charge. See attached pdf Customer report. Shows replacement Led panel, & controller board. No sign of ghost touches so far, and really working well actually. Early days yet, but I also note elsewhere in these forums someone mentioned their tablet not working properly 'upside down'. I neglected to mention it earlier but upside down isn't as funny as his respondents made out. I use mine often lying on the couch watching TV, with the tab upside down. Reason I mention it now is that mine acted up in those circumstances too. Anyway, that's fixed too.
Hi everyone, as the title says, i've been having some problems with my surface RT (from the first generation) that I bought 2 days before the Pro was released in 2013 xd
First, a while ago, a year I think, my Vol - button stop working, I don't know why, but it just doesn't work until now. *
Second, I've been realizing that the speed and the fluently have decreased, or in other words, some lag has started to appear, even if I restart the tablet. Do the ARM version of windows suffers the same problems than its x86 counterpart? I mean, that it gets slower and slower as time goes by?
And third, and the most important, for a week or two, the right edge of the screen, doesn't respond to touch, so I can't open the charms bar or press "x" to close desktop apps, unless I use a mouse. It is like an inch wide or maybe less and involves all the "height" in landscape, but when I touch that place, the screen detects it like if I'm pressing either its left or exactly at the right edge. Curiously, it is intermittent, sometimes it works fine like it should, and in others it just doesn't work. Also, sometimes it goes crazy, and that sectors act like if i'd pressing and moving my five fingers all across that area, and I have to press the lock button for make it stop.
*I didn't mention it, but my Vol + button is starting to work weird too, I have to press it several times for make it "return to life" and response.
Well, the touchscreen problem is the one that worries me the most, but due to it is intermittent... could it be related to software instead of hardware? Could it be solved?
Thanks in advance for the answers.
Regards (I always doubt if this is the correct word for the expression that goes here xd)
Edit: I forgot to mention it, but i have win 8.1
If you haven't deleted the recovery partition, you can "refresh" the tablet to restore it to a like-new-install state. That should clean up any actual decrease in speed (as opposed to mere perception of the same).
The hardware issues sound like, well, like hardware issues. You can't really do much about those except get the thing serviced; it's not very user-repairable.
I thought that using the recovery to restore it to its original state will be the option, but is anyone else getting similar issues? I was thinking that maybe the problem was an update, because I have them programmed to be installed automatically, and maybe I didn't notice it.
I guess i'll do the "refresh" after I backup my files on December for vacations if this problem doesn't disappear by itself.
This is getting weirder :S, now I can't open some modern apps, they stay forever with the loading icon in the center, this occurs for example, in the store app or In the news app, but weather or desktop (luckily) work fine.
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.
