Touch screen problem on Motorola Defy - Android Software/Hacking General [Developers Only]

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

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.

Help..Jasjar going into auto powersave and no response on button press.

Greetings,
I just upgraded to the 2.02.00 ROM last night but still have the occassional lockups. I need to do a soft reboot to get the phone to respond. I believe when it locks up, the radio is still running since I see the blinking Green LED for the GSM. I have to switch off the POWER MANAGEMENT option of "Turn off in x min in not used" for battery power to be able to use the device for calls. The only level of battery saving I am stuck with now is the Backlight auto-off and the beam settings.
Is this something others are having as well or are any applications the culprit?
Thanks in advance for your assistance.
Regards
BHAMEED

I can confirm this behavior on my MDA Pro (G3).
All ROM versions the same like Bhameed's on my MDA, ...except bootloader of course.
Anyone else noticed this on 2.02.00?
Hold on, can you guys be more specific with this? Are you absolutely sure it doesn't come back on when you PRESS AND HOLD the power button??? Really sorry if I sound like I'm being pedantic, but just from what you've written it sounds like you don't know how to turn on the phone???
hahahaHAHAHA!!! awesome reply spyder
ok, yeah i was thinking this is an issue of not being able to turn on your phone.
yeah what's going on that was different from before?
There have been only few moments where you think "Surely not"... I hate those moments, I'm just hoping this isn't one of them! If it is a genuine problem it's pretty serious and needs to be addressed, but if not.... well, I don't think I should say much more
Please please please say this is all a big joke. I'm tired, please excuse me.
I confirm this behaviour!
And more!
My Qtek freezes... freezes... and then PUFFF. Dead.
I wait some minutes (30 minutes) and I can turn it on again.
I'll send it to qtek.
Mine has a thing sometimes where there will be a pause between pressing the power button and it coming to life... sometimes if I get impatient and press the power button again it will turn it back off before it's come on.
I don't really get it though. Does it freeze while it's still on, or while it's turned off? If it freezes when on, there's plenty of info about how to prevent freezes (mostly 3rd party apps + reg tweaks).
If it really does freeze when off, then please let us know anything more on the issue that you can.

Mine freezes everywhere. Bootscreen, Pin code menu (when u type your pin). It depends.
then pda doesn't turn on.
Many problems.
Just go to the assistance. :\
1.Sometimes it freezes while its on. For Instance I had program opened and then whenI tried pressing X to close nothing happened. I had to use the red hardware button to close. Wonder why.
2.I too agree while the phone boots and is searching for network, it takes very long, Meanwhile when the pin enter screen come up, unless the network is fully searched one cannot enter the sim pin code, it has few freezes. or at time the phone signal icon disappears on top bar and again you need to reset the phone.

Again, I don't have this problem for some reason... I get very few freezes at all.
I think we're getting away from the original point of the post though... and normal freezing is well documented in most OS threads with means to prevent it.
Same here...Confirmed. Tried all button combinations to get the display back (short presses and long ones), but then end up having to do a soft-reboot to finally get the phone to work properly....

And then you don't have other problems? Like freezes?
EDIT: I flash the original rom but the problem still here
I wonder if this could be a memory leak like someone suggested.... I'm sorry guys, I haven't experienced this problem, and I haven't seen any posts about it until this thread, is there any chance you guys with this issue can keep an eye over your memory status over say a couple of days to see if there's a leek and keep us posted? Once we find out what the problem is it should make a solution easier.
I experienced this problem as well using a cooked WM5 ROM on my HERM200 the only fix I found was migrating to another ROM. I'm currently using CUSTEL_Cing_v1.3, the battery life sucks but I love WM6, it is so much faster, I'm still tweaking and trying to resolve some other issues but other than that I am quite happy with it.
If you are experiencing the lockup I would suggest moving to another ROM as an option, that worked for me. Although a clean install usually fixes a lot of problems.

Keyboard does not work after ROM Change

Hi all,
I read through a lot of threads and downloaded tons of ROMS for my TyTN II. Most of them were from dutty's or no thrills. Problem however is that everything seems to work, it is also very fast.
However after a while my (hardware) keyboard and also the buttons (e.g. sliding wheel and keypad on the front) does not respond anymore. When I click any of the hardware buttons the light goes on so it does react on the buttons, however it just doesn't do anything...
Did anyone else experience this issue? I will no try to switch back to the original HTC rom (6.0) since I have no choice but if anyone knows how to fix this?
P.S. I just noticed that all my buttons do not work, it is no hardware issue since It does work after a hard reset, might be caused by incompatible applications? (e.g. SPB phone or SPB theme)
Kind Regards,
Nico van der Linden
If a hard reset fixes your problem each time, then it sounds to me like a bad flash. I would try reflashing the ROM you are currently running. Make sure to hard reset immediately after the flash also.
ok thanks, I'll try to download the ROM flash again , and perform an hard reset directly after the flash. Hopefully this times the ROM update will go better.
Regards,
Nico...
Just my 0.02$:
I think this is related either to WM6.1 builds or to a hack/fix/setting that most custom ROMs use.
I flashed Dutty's Apr 01 ROM and i had this issue. Then i flashed Mobile Vista 1.3 and it happens again . So it's not present in just one ROM, or just in ROMs cooked by a certain chef.
By "issue" i mean every once in a while the touchscreen stops responding to clicks and the keys stop working (but the keys backlight comes on, so HW seems ok).
During this unusual behaviour i noticed that the device is NOT frozen - BatteryStatus updated it's CPU usage while the keys and touchscreen didn't respond, so only the input stops working, the system is ok.
I have a feeling this is a common issue, but people see it as a freeze, and think their processor is too loaded, and they don't report it.
EDIT: Oh, and i got flamed and ignored whan i reported this here: http://forum.xda-developers.com/showthread.php?t=385080
EDIT2: I have a feeling this will get a lot of attention soon, just like the time i noticed the Tytn II is underperforming, and the fact that's it's missing 3D HW support

The quickest way to get out of that situation is turn off the backlight and turn it back on again, aka power button...and your screen will work again.
Also I noticed that if I flash the radio again my screen taping problems go away.
Also sometimes flashing to the original shipped ROM and then flashing back to a WM6.1 ROM also works.
Well I do not have an problem with the touch screen, this always keeps working (although the device does get VERY slow sometimes) . 'Only' my hardware buttons do not work anymore (including the hardware keyboard). It is strange that it does work after a hard reset or an install of another ROM. However, also then it stops working after half a day or so.
It might occur as soon as I change the hardware button assignment but I am not sure about this yet.
However, if anyone knows a ROM where this does not occur (e.g. an original HTC WM6.0 ROM dutch or english) then please let me know which one. I just want a working Tytn II back and I do not care anymore which version .
Kind Regards,
Nico...
Ah by the way, when this problem occurs it does not go away anymore when I turn of the device. I also tried removing SIM, memory card and battery but after it is started again the problem remains. Only a hard reset solves it....
But I am a bit confused? Is there nobody else who get these issues???
yeah...
i can confirm all of your bug...

Screen Calibration is Off

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.

[Q] Touchscreen freezing randomly - please help!

Hi, I've been using ViperS 5.1.2 for some time now on my Sensation XE, and it used to work great for me. But since a few days I've got this really annoying freezing problem and I just cannot find a solution.
The touch screen just freezes without any reason, sometimes after using the phone for half an hour, but most of the time within a few seconds after unlocking the screen. When it freezes, the screen won't respond to anything, also not on the back or home button. If I use the on/off button though, the screen will respond again for one or more seconds. This happens randomly; a lot of times I can't even unlock the screen properly, and the rest of the time I only get the screen working normal for a at most 10 seconds. This way it can take a few minutes just getting to the settings menu, for example. The phone does not report any error; after using the on/off button it just goes on where it froze. Also the phone reacts to tilting the screen. Or when playing a video, this just keeps playing normally. So it seems to be purely the screen itself...
I tried a lot to figure out what could be the cause of this problem: uninstalled a lot of recently installed or updated apps, checked the amount of free space/RAM, cleared cache, Dalvik, used nandroid backups to return to a previous (in the past good working) state, tried if removing the sd card would make any difference and finally flashed the rom again. All to no avail; the problem keeps occurring. At first, after trying out a possible solution like the ones I've mentioned, it looks like this did the trick. Sometimes the phone appears to work normal for at most half an hour. But then the problem occurs again, and will at that point occur at a high frequency.
I am out of idea's right now and am getting quite desperate. I need this phone to work properly badly, as I will go on my vacation in a few days and really need to be able to use some of my apps then. So I do hope somebody can help me out here? Any help would be greatly appreciated!
Does it do this while connected to the charger or usb.??

Yes, does not make any difference. I found today that the phone is now also acting strange in clockworkmod recovery touch, that's for the first time. Can't properly use the touch screen there either any more, only with hardware buttons. So now I guess this should really be a hardware issue. Maybe the phone is just dying...
Yess its a common thing for our phone to act that way while charging.... It has somtheing to do with its poor grounding. You can find threads to help u with how to solve it.

Touchscreen randomly not working

Hello guys,
This is not necessarily a specific S8 plus thread, it's more of a software/hardware general related issue. I just replaced my display two weeks ago because I cracked the screen and the display a while ago.
After replacement, I got the phone, everything was good until I dialed *#0*# and started testing the touch. It appears that theres a portion in the middle of the display that is not working (the boxes wont go green when touching them). The thing is that, sometimes, the touch passes this test as in everything is ok and sometimes, it fails.
From time to time(pretty frequent) it randomly freezes and I have to hit the power button to open and close the screen to make it work again.
I just flashed the android Pie hoping a complete erase would fix the thing but it appears it didn't. Do you guys know any solution to my issue besides returning the phone in the service?
Thanks!
