Hello, I have recently discovered a very annoying problem with the touchscreen on my Motorola Defy:
I have noticed that the touch screen acts strange sometimes, so I have installed a touch test application(Touchtest by Hermit). In this application I have noticed that if I touch the screen in two different points in a fast succession, a line appears between these two dots. This makes a lot of application that require multitouch pretty much useless, because I have to restart the application to have the touch screen working again.
Is there any solution for this? I have heard that this may be a software issue, so I have e-mailed Motorola, but they have not answered yet.
I have attached two pictures to illustrate what I am saying, one taken before this strange error, and one after pressing on two spots very fast. You can see the line connecting the dots in the second picture. I can make a video if you still can't figure out what I am saying.
Thank you.
Im having a very similar problem here on my defy. When I play games on psx4droid and when I keep pressing x key, it stops working for a while then I have to release the button and when I press it again, it stops working and it continues
I encounter similar problems with my Defy.
When for instance using slide to unlock , 1 / 5 sildes fails. I have to slide 2 - 3 times until it unlock.
It also scrolls very slow in applications and the same thing happens when typing a message.
Solution : Unse lock button.
It currently runs Pays ROM, but the situation appeared since I installed 2.2.1.
I don't remember having this problems on 2.1.
Don't know if the situation is only related to software but it is really annoying.
Found this info regarding touchscreen slowness, but I am using the original charger so it doesn't apply for me.
Motorola Defy Touchscreen Problem
I recently got my Motorola Defy,my Defy's touchscreen acts sometimes really weird, on keyboard it's hard to enter 'r' or 'b' and some other characters, it takes little while to unlock the phone, it automatically opens applications, I don't know if it's due to faulty handset or software, I am considering it returning to Phone4U and get a replacement handset.
What version of Android are you using ?
Same problems here, but I think it is a software issue.
I'm having the same problem on my Defy.
After a while, the multi touch stops. I posted on the Motorola Forums
https://supportforums.motorola.com/thread/44733
but no response.
I used YAMTT and when having two touches, after 20 seconds, one of them disappears
This is repeatable
2.51.1 UK with 2.1 Android
Well, it is clear that this is a problem that affects many Motorola Defy users. But I wonder if someone could fix this thing?
Looks like the new software version 2.51.1 did not fix this bug. I haven't tried it yet, but I see some of you have.
So it looks like our only solution could be a developer from XDA. Could someone help please?
This is ridiculous...i've sent my phone to motorola only because it was giving this problem and basically what i think is that their own software is causing this problem so i'll be waiting for 3 weeks and when i get my defy...it'll still have that problem...Ridiculous...
I did a bit more experimenting.
I flashed the 2.2 Finnish blur, multitouch still disappears after 20 seconds using the touch testing programs
I also booted into Safe Mode (vol up + vol down during boot)
The same problem persists; I was using gallery image zoom to test.
However, I got my friend who has a Motorola Droid to install YAMTT. The multitouch lasted about 30-40 seconds. Not sure what to make of that. He's running some version of Cyanogen Mod on Android 2.3

Mine sometime stop response after few seconds
really wierd
Tell me who is on stock rom and is having problem..because im on 2.2 leaked..so i cant really say if u hv this problem on 2.1...
I got this response from a Motorola employee. Anyone know of a way around this?
Motorola Employee said:
If you touch the screen and don't move for a long time, the screen will eventually try to ignore that touch as it'll be considered invaild. That's what you're seeing. If you continue to move your finger(s), touch will continue to work. Also, when you release the screen, it acts to clear the invalid touch region that you generated earlier.

have simular problems............100 procent hardware problem..... if i twist phone a little it will go back to normal for a while
any ideas for disable it?changing some parameter or something?
I have the same problem. screen sometimes go crazy. i am using stockrom eclair SEA 2.59. sometimes it seems that it tap icons or part of the screen even without I actually tap on something. and it seems it affect the capacitive button under the screen. I am not touching the search button but the search box suddenly appear.
I have to push the power button and unlock the screen to make it normal.
somebody please help us. I am also having this weird problem. Touchscreen gets pressed itself not everytime but it happens very frequently. Tried everything, hard reseted too.
At least I gotta hope that its not a hardware problem as many of u are also facing this problem. Any body please confirm if flashing cm7 has helped u or any other solution.

i returned my defy months ago but what you can do is, try to flash cyanogenmod on your defy...that should fix the problem.
Hi, I've registered myself just a minute ago, reading the link that efpod left here and I've remembered that I charged my Defy with a Galaxy S i9000 charger friday (I've charged it once the batery was drained later with my original charger) and today it is failing A LOT, it's really anoying.
I got Cyanogen Mod (latest) installed on my phone so that doesn't fix the problem.
I'm uncharging it with "StabilityTest - CPU / GPU Test" and when the battery drains out I'm gonna charge it with the original one, after that, I'll test it during the day and I'll leave a messege to keep you informed.
I got nexus s (i9020T) recently and found the touch screen unresponsive sometimes. I've already tried several launchers(adw, lancherpro, go launcher ex), and it seems not launcher's problem. I've also tried to flash different ROMs, including CM-7rc2 and stock 2.3.3, and the problem remains.
Later I tried to bind Multi-touch Visualizer 2 to long pressing home button, and found the when screen is unresponsive, it can still detect press near edges very well, but not the center. While I press at the edge and drap across the center, it keeps tracking my finger correctly. In addition, Locking and unlocking the screen can solve the problem temporally.
I'm confused by the strange behavior, anyone experienced similar issue?
more info from test,
I connect my phone with adb, and tried to "cat /dev/input/event0"
The behavior confirms what I see in Multitouch Visualizor 2: the when the center of screen is unresponsive, nothing can be read from the device node.
I read the mxt224 touch screen controller doc, and it seems the chip features self-calibration, and thus I believe the "lock & unlock" will trigger the chip to tune it self in some way. I don't know kernel very well, so I cannot find the source code Any help please?
FYI. we are not alone.

I got this problem too whenever my phone is in my pocket facing inward.
I have tried to open the calculator to see which part of the screen having problem. Mine is usually the "8" and "5" location unresponsive if my phone stayed in my pocket facing inwards for a certain period of time.
The problem will goes off after couple of mins when i can feel that the phone is cooler than my body temp.
I knew this happens to the Dell Streak as well.
I seem to have a problem with the letter p on the default honeycomb keyboard - it doesnt seem to let me use the letter p correctly. If I hit the key i the dead centre, it is completely unresponsive. But around the edges of the letter it works fine.
I dont think its and issue with the touchscreen as it works fine in other apps (no dead spots) just i the keyboard in lamdscape mode.
Am I completely crazy or can anyone else replicate?
Actually, after playing with it a little more there seems to be a small area of the screen completely unresponsive to touch.
Could this be a software issue or is it likely to be a fault with the touch matrix on the screen?
Have you tried restarting the tf?
Try turn off and then turn on the screen. Also check this thread out: http://forum.xda-developers.com/showthread.php?t=1068569
Thanks for the quick replies. Just restarted it and it seems fine for now. Didn't realise there was a known issue wrt touch screen responsiveness
Hello,I bought a HTC Desire S around 4 months ago.
From past 2 days i have lot of problems with it.
1.Home screen button not working
2.Q,A keys are not working while typing(they work when i rotate the screen)
3.Wen i rotate the screen and start typing the whole keys on the least bottom dont work.
4.Sometimes if i press back key it goes to selection option...sometimes whole phone hangs.
5.Im not able to download from market...after i click download it shows downlading icon but it never starts download.
I made factory reset for couple of times but no use.
Any one have some suggestions?
numbers 1 to 4 seem like some sort of problem with your touchscreen... Have you tried wiping it with some clean cloth after breathing on it? My back button has some issues registering touches once in a while, but wiping it helps always
Regarding 5, I don't know really, but have you tried using the webmarket?

ya i tried wiping it but not working
Does the area where your Q and A keys are when in portrait work when the keyboard is not on? Can you use it to click items, scroll webpages etc?
One other thing you could try is the calibrate option for the keyboard. (somewhere in settings-> languages I think, it's been a while since I ran an Sense ROM).
If both yield no result, it sounds like a hardware issue to me, and you might be best of to invoke your warranty.

I am not sure but it looks that your touch screen is damaged. One my sister had dropped her magnus mobile accidentally then touch was not working in middle part. So she had to replace her whole touch screen. Her model was white one.

Yes it is clear that your touch panel is damaged, go to the service centre and repair it as soon as you can
If your mobile is white then only touch will be replaced. Service center charges 2350 ₹ including tax.
If its blue, then whole touch n display will be replaced. Service centre charges 6350 ₹.
If its in warranty then you are lucky.
