I am noticing that upon returning from a locked screen, the sensitivity on the edges of the screen is very poor. Over time, however, it becomes perfect and I have no issues selecting top left/right buttons, and button savior buttons. Has anyone else experienced this?
I have used the sensitivity calibration apk as well, if that matters. I am hoping there is a way to have full sensitivity all of the time.
Thats because when you first turn it on or brought it out of sleep the tab is still doing some routine stuff with te programs. Let it sit for about a minute.
Same with your pc.
Have you done the calibration.ini file and place it on your SD card (and SD card2 if your running vegan) then boot your gtab up without touching it so it can recalibrate the touch sensors?

This. The app did nothing for me, but the calibration.ini fix made a HUGE difference. I was skeptical, thought maybe it was a placebo effect since the app didn't fix it for me, but nope, registers every single touch now. I feel bad for people who buy this without knowing there's a way to fix the sensitivity.

A friend brought me a good one today. He has an AT&T Touch Pro with a touch screen issue.
He brought me the phone months ago and I flashed the ROM. All was good. He then deleted a bunch of files one night accidentally and hard booted the phone in an attempt to get the files back. Upon hard reboot the phone hung at the calibration screen and he could not get past that. To describe, the screen calibration works on 3 of the 4 corners, if you hold the press the stylus to the screen quite firmly, but the top right corner will not calibrate however long I told the stylus to the screen.
He brought it to me today and I figured that a fresh ROM would resolve the issue. So I loaded a new ROM and the phone hung again at screen calibration. So I did some research and found a "welcome.not" work around to get us past the screen calibration issue. This was successful and I was able to get us to the home screen.
The issue is that the screen is very unresponsive and I have flashed the device so it's not a ROM flash issue. Is there a driver he might have accidentally deleted that is not reinstalled on a ROM flash? I know I am probably grasping at straws here but I thought this community might have some insight to what the issue is.
I have also considered the idea that I may need to replace the digitizer for this phone if that is the issue and am prepared to do so but thought I would throw this question out to the community for any tips/tricks or ideas you may have before cracking the case on this thing.
Thanks for your help in advance.
--Mike
Oh and I forgot to mention that sometimes the screen works if you tap it continuously but most times, there is no response.

The calibration of the screen
IWPantel - Thanks for referring to my blog
To stop the welcome message, you need to put the Welcome.NOT in the root of a sd card or of the device. I don't believe this is your issue, however.
There are typically three reasons why the screen will become unresponsive.
#1 You have a bad touchscreen. Assuming that the screen was working perfectly, I highly doubt this is your issue.
#2 You are calibrating the screen with the stylus straight up. Believe it or not, the touch point changes if you are straight up and down, or if you have the stylus as if you are writing. The angle will affect the touch point.
#3 You have a conflicting .reg file in the Application or Platform directory of the handheld. The calibration settings are stored in the device's registry and they need to be updated. If you did a persistant registry tweak (where it exports the registry into NV ram, the calibration settings will overwrite the calibration settings you create on system startup.
Feel free to contact me with any questions.

Brent, I had the same problem here! My Fuze simply stopped responding to my touchs....
#1 Taking this as true
#2 I tried a hard reset, but nothing happens. I can not touch the screen to calibrate
#3 I just can not understand what you proposed.
Please, help me!
I don`t know why, but my cell just back to normal!
Now it's everything working!
@brentblawat - How come you are a Junior Member when your answer is so hardcore.
Anyhows, I have the same problem with my phone, I have tried all the software tricks I could think of. I guess your point 3 asks us to manually enter the calibration data in registry. Have tried it doesnt work.
I cant replace the hardware as I have Tmobile MDA and I dont get the spare parts for this here. the digitizer is different from the one in Touch pro.
Naturally I bought a g Tablet Saturday and Woot has them today for almost $100 less! Oh well. Big big big improvement from my old FlyTouch2 which was a great idea poorly executed.
Immediately flashed VEGAn with supplements etc. All working VERY well but a few questions/observations.
1) If I wanted to hook this up to a USB or Bluetooth modem (well, actually a BlackBerry) it looks like there is no setup for this? Yes, I know if I could find a way to make the BB broadcast WiFi but its corporate so that's a nonstarter.
2) When I hold down the power button, the menu that comes up it clipped off at the bottom. Is that normal?
3) Screen lock on Kindle software is not getting the accelerometer fix somehow. The trick was to put the thing in portrait UPSIDE DOWN and lock the screen. That caused it to lock it 180 degrees off. But then when it is locked you can go back to right side up (to me, right side up is with the buttons to the top). Of course, if you want to lock it another way you have to experiment.
4) Camera Fun shows camera upside down. No big deal -- again accelerometer I think.
5) Sometimes I am sure the machine is asleep and when I turn it on it is booting from the birds screen. Anyone else seeing this?
6) I don't understand the .nomedia thing although I've read a lot about it. I don't seem to get files erased, but nothing shows up in Video. But if I navigate to the folder (on /mnt/sdcard2) and play videos that's fine. Then later the files will show up in video. Whoops spoke to soon. Now they are gone. What's up with that?
7) My old tablet had GPS but without the external antenna it was worthless. But it still managed to find rough location with WiFi somehow. I assume by figuring out the geographic location of the IP. That doesn't seem to work on this machine. Yes Use Wireless networks is checked in Location and security.
8) What's with the little plastic cover? How hard is it to take out? I don't want a little rubber dingle rolling around inside.
8) In System Preferences, About Device | Status consistently crashes.
9) Does the audio jack support a headset or just headphones? Yeah I know -- I could just try it.
If it matters I'm using Launcher Pro.
Still and all the VEGAn ROM is superb. Compared to the FlyTouch this is super fast, the screen is a joy, and the battery life wonderful. And with the woot deal only about $80 more than a FlyTouch2.
Ok I'll answer some of my own questions:
5) I think this is the unresponsive power button problem. If you press and wait it seems ok. If you press, get impatient and press again you might reboot.
9) No, at least not with a Blackberry headset.
Most of these are answered on the forum somewhere, but I'll give it a shot..

Known issue.
These aren't much help (maybe reassurance?)
1) Pretty sure it's wifi only. Have trawled the internet looking for a usb or bluetooth alternative because wifi hammers the phone battery
2) It happens on mine as well, so it's not just you
5) Same here - I just turn it off when not in use now
7) Only GPS functionality seems to come with the need for an external GPS unit
8) Think this is normal
(Re reading above, it looks like I'm negative re VEGAn - this is not the case. It is way better than what came standard and does everything I need it to do)
Yeah I like it too. Haven't tried the others, but very satisfied with Vegan.
Another observation: Long pressing the Menu button (hardware) brings up the keyboard. However, long pressing the menu button on the status bar does NOT have that behavior.
Clemsyns newest kernel will fix sleep issues. Also has some other great improvements too.
Buttons on status bar do not respond to long presses. Home doesn't bring up its usual long press of recent apps either. Funny, i Never even tried long press on status bar keys before now.

I have Pershoot's kernel. I'll try changing. I presume I shouldn't need to clear too many things in CWM after flashing a kernel. Maybe the Dalvik cache?
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.
Hello all,
Awhile back the touchscreen on my Sprint TP2 (RHOD400) was off. I click in one spot, it clicks an inch high. Sometimes more, sometimes less..I tried calibrating, but I couldn't even click the center target once. The problem stopped for awhile, then started up again last week. This time the problem is worse. I press in one area, it presses one to two inches away. I have the phone in landscape mode and try to press the upper right hand corner 'x' and it brings up the notification window. Sometimes the lower right part of my screen is completely inaccessible, and I cannot send a text for quite awhile. Other times it is fine, but not fine to the point where I can get super accurate clicks. I was running Mr.X rom, and flashed to Mighty, but this did not solve the problem. I have also cleared storage. I used to run haret android for awhile, would this have caused any problems? I thought I should try that again since I can force the phone to use a calibration.txt file that works for sure, and see if the phone is "fixed" then. I guess my options are...
Try haret android again
task 29?
reflash?
be sad, it's a digitizer issue
(tldr) Touchscreen is off, but not always by the same amount. Reflashing wouldn't cure it and I can't calibrate it. Targets keep going around and around after the reflash, where before I couldn't get them to click even once.
Maybe one of those will fix my problem..I hope so, but I posted here to see if anyone else had heard of an intermittent touchscreen issue like this?
Thanks for reading/help guys.
Can a mod move this to http://forum.xda-developers.com/forumdisplay.php?f=488 Touch pro 2/Tilt forum? I feel as if I posted it in the wrong forum and I'd get more responses in the other. Thanks!
Have you tried pressing the two volume buttons at the same time to get to that calibration screen. Then try to calibrate and see what happens. If this does not work for you then I would think its a hardware issue.
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.
