I'm the [almost] happy owner of a Defy whose digitizer, from time to time, stops working or goes crazy.
The "goes crazy" part it's obvious and it only happens in Angry birds. The game keeps on zooming in and out like, beside the finger that I am putting on the screen, there's an invisible one that shifts on the screen. Seems to be app related as this doesn't seem to happen in any other app.
On the other hand, from time to time, the digitizer seems to stop out of nothing. I haven't noticed any particular pattern on this but it might be driver/app dependent too.
Both of these situations are resolved with a blanking of the screen (top button).
Does anybody else have this kind of problems? Any idea where is the problem?
PS: If I get any more patterns I'll get back.
Yes, very rarely. Screen will not respond and have to time out screen and then it's fine. Usually happens while on charger.
I have trouble with most multi-touch games. After a while, the screen stops responding. Sometimes if I release my touch temporarily it will work again, but by then I'm dead or have crashed Not sure if it's just my fingers sweating onto the screen or something!!
I tried the multi-touch tester app in the market, and it tracks two touches without a problem; so it only seems to happen during games.
eg
Gun Bros
Mini Squadron
The multitouch tester also does the bug. Just try to simulate playing in the tester and you'll see sometimes one finger not responding. But I think there are very few phones with perfect touch screen for playing games. So not a big bug for me.

About 2 months ago I started getting phantom touches on my screen, always on the right side. In the app Dotty, I could create the touches by moving my finger near the right edge until a circle would appear and start barely moving up and down really fast. This would be the primary touch point and other touch points would show on the screen in Dotty but in any other program all secondary touches were ignored(keyboard, homescreen). This created the illusion of the touchscreen simply not working. To fix it I had to sleep/wake the phone a couple times until it went away. This issue would come and go and seem to be really bad for a day then there wouldn't be a problem for a week. As of now, the phantom touch point problem seems to have gone away. However, the right 1/4" of the screen no longer registers touch. This mainly only affects the P key but is quite annoying. The strip that doesn't work runs from x:287-320(edge) in Dotty. I've flashed, re-flashed several roms and can't seem to fix the problem. Any ideas? Is this a digitizer gone bad? Should I contact HTC/is it covered by the warranty?
I have 2 annoyances with my Xperia Play -
1) The Accelerometer is off-level. When i start an accelerometer game, the thing affected by the accelerometer normally starts to tilt forwards. I need to angle the phone to make it "level" properly. Games that can reset the accelerometer work fine obviously, since i can reset it, but games that do not have that option are unplayable as everything tilts the wrong way and is not level.
Anyway i can reset the accelerometer?
2) Sometimes when i touch the very right hand side of the screen in landscape mode, the left hand side of the screen activates. Very annoying when typing as wrong letter appear. And some games get annoying. Any way to reset the touch points of the touchscreen?
Also, does the Xperi Play have a Gyroscope? some say yes, others say no. If yes, can i perform a reset on this too?
Thanks for any answers.
Most games are made that the neutral position is under an angle and not when the device is flat. This is done because most often you hold the phone in your hands a bit before you and you look at it from above with an angle. I don;t know of a way to reset this.
Also I don;t know how to calibrate the touchscreen. You can use this app: http://forum.xda-developers.com/showthread.php?t=1045374 to check where the touchscreen is faulty.
Hi, I have a similar problem with xperia x8. When playing e.g. the 'Falldown' game from the market, the ball goes to the left in neutral position. It's quite annoying...
Hi all!
I hope someone could help me,
My Desire Z touchscreen works weird, sometimes it does 2 unusual things:
-sometimes when trying to scroll it will zoom in or out like there is another finger there but there is not. If i run pointer location test, then it shows there is screenpress in the middle, but im not pressing it. the only way to fix it is to turn off the screen then turn back on.
-other times, the problem is similar, about 1/4 of the touchscreen in the middle/horizontal does not recive input. And the whole screen wont recognize touch correctly.
The problem happens mostly -but random- when i play games, or read pdf!
Is this problem related to the digitizer? I have tried more ROMs, the same problem. Not charging, no screen protector on the device, no break on glass.
Thanks in advance
Hi
I bought a new RHOD100 and am running Stock WinMo 6.5. First few days the phone worked beautiful. But about a week of usage landed me in this condition.
The screen only lights up with the keyboard is out and not tilted. Other than that, if it's slid in (portrait mode) or when it is tilted up, the screen freezes to whatever it was like when the keyboard was slid out. The touch functions work, I can hear screen tap sounds, and if I click on the right icon things open and close too, but the display remains frozen until I slide out the keyboard and/or undo the tilt.
Any ideas how to fix this? Is that hardware or software?
I have never dropped it, nor exaggerated the tilting.. Can it be the Flex cable?
Definitely hardware... almost 99.99999999% sure this issue is hardware.
I'm betting it is indeed the flex cable. If you're feeling brave, you can attempt to take the phone apart and see if you can find the issue - keep in mind, this is very delicate and tedious work. Need a steady/careful hand and a lot of space! Good tools help too .

Hi everyone.
I have recently had my screen replaced. After playing around, i quickly noticed that my keyboard screws up when i start typing.
The faster i type, the worse the problem is.
I checked touch response times and achieves normal times of about 60ms, however, i turned on touch overlay in developer settings and noticed that if i touch opposite sides of the screen quickly (to simulate typing), it would draw lines between the touches as if i was dragging between the two points.
This is what causes my keyboard to do funky stuff and heavily lag when typing fast.
Please note that this never happened before the screen replacement, and a hard reset didnt fix the problem.
Is there any software fix for this, or do i need another screen?
thanks.

I mainly work on iPhones, but it sounds like your digitizer is out of calibration. Don't know if there's a software fix for it, but hopefully this will point you in the right direction. Also I'd take it back to the place you had it repaired and see if they can fix if it's still warrantied.
