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

Defy doesn't support cynogen mod and 2.3
I was messing around today and even the single touch disappears after a while
30 seconds or so
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.
Hi I recently got a chacha from a friend and certain keys don't work as intended like
pressing d gives me five and the back button makes question marks.
The key still work so I'm wondering if there is a hardware calibration tool
For the keyboard, I have tried resetting the phone and they are still messed up.
Thanks!

I also have this problem, but only when I have the phone in my pants, and creates moisture in the keyboard, especially in summer.
I brought the phone to help with a problem with the green and red buttons. Them I have fixed the problem, I have recalibrated the phone, but the problem of crazy keyboard will occur.
Thanks for reply but..
Thanks for reply but the think is the problem is not disappearing and I cannot login into google and other services because of the keyboard.
The phone has probably been dropped many times so i think its a hardware problem hence recalibrating the keys to what they should be doing may help. I have tried button mapper and tools like that but it requires root access or limited funtionlity
Hey All,
My softkeys (menu, home, back and search) are acting funny lately. They only work when they are not backlit, ie if they are not backlit they work properly but after the first initial press they don't work again until I leave everything alone for a few seconds and the backlight goes off.
They respond (haptic feedback/slight blink) when I press them while they are lit, so I know the actual keys themselves are working fine.
I initially thought this was a firmware upgrade issue (Running latest CM 10 right now) but the issue persisted even after using Heimdall one click back to stock i997 AT&T rom. It also has the same issue with the latest Beanstalk ROM as well.
Does anyone have any suggestions? I'd be fine with disabling the backlight on the keys if that will solve the response issue but I can't figure out how to do that.
Hello xda,
I have a really strange problem with my Sensation, it's a new phone that I won in a competition by HTC, I received the phone already S-OFF
The problem is that the Volume up button don't work, the volume down, power button, and capacitive buttons all working ok..
But when I reboot into bootloader, The Power button Don't work, the Volume up button don't work, and when pressing volume down it moves the cursor to the up..
So in bootloader, the volume down button acts like a volume up button and all the other buttons don't work.
The question is this problem a Hardware or software problem? what do you think? should I send it for repair?
Thank you guys,
Cheers
PS: I reinstalled a full RUU 2 times with no luck

Try using the buttons without the back case (They look like black plastic (darker than surrounding plastic). Sometimes the back panel could be faulty (at least from my experience). Since you flashed RUU I can assume that it is not software (as it replaces all software/firmware parts on the device). But did you try using a different RUU? Do SuperCID first. Else you might have to bring it to service, because this sounds like a hardware problem (albeit the bootloader part sounds weird).

Thank you for ur reply
I tried with the case off, and yes I triend using a different ruu, and I also think of a hardware problem, but which is really weird is that the power buttons works when running the phone but doesn't work in bootloader !! that proves there is no hardware problem with the button right?
and the volume down key, when running the phone it acts normally but in bootloader in acts like a volume up !!!
that's why I thought of a software problem

Yes... that is possible. But since you switched HBOOT and firmware, it means that it is (probably) not software, as you tried different versions. The buttons may work, but the problem could also be on the board itself. I don't really know how to explain this, but it seems to be the case.
You can try a ROM that assigns action to each key (or find a mod somewhere... I'm sure there is one), and mod the ROM you run to work with Slide To Wake and virtual volume control. That's how you can live even without buttons (unless a solution is found). Also you can flash a touch enabled recovery via fastboot and operate those things with adb. It's not ideal, but it works, and could replace the physical buttons.

Thank you mate,
luckily the power buttons doesn't work only on bootloader, but does work when running the rom, the volume up buttons works also, capacitive buttons work as well, but for the volume down there is no problem I can perfectly live with it, I can adjust volume in settings or just hitting volume up and then sliding the on-screen slider

Glad to be of help (Albeit didn't really give a solution). You can also debug this with a button testing app. I never really looked for one, but I'm sure you can find one if you look for it.
Hi All,
The capacitive buttons of my OPO suddenly stopped working. My phone didn't drop and has no physical damage. I tried an hard reset by flashing CM11s (from COS 12) via unlocking bootloader and executing the right commands in Fastboot mode, but the problem still persists.
I switched to screen buttons, but I prefer the physical buttons for my usage.
My phone is 9 month old and It's very strange that an hardware problems materialize in this way (no new app installed when the problem arose).
Has anyone experience the same problem or someone know how to fix it?
Thanks in advance for help
