I just started having this "bug" yesterday. Basically, what happens (randomly) is that when I press the power button, remove the stylus, or slide the phone open to wake it up I'll be met with a black/blank screen. The backlighting will be on, and the phone is responsive (can receive messages, make calls, sounds/notifications work), but I won't be able to use the screen. If I use the power button to turn the screen back off and wait a few seconds, the screen might start working again. This is completely random and I cannot duplicate it with any guaranteed process, but it seems to be when the phone is waking up from standby. After a soft reset, probably half of the time I'll be met with this same delima, which leads me to believe it's hardware and not completely software.
At the same time the phone is also struggling to re-paint the screen from the change of Landscape-to-Portrait and visa versa. Also opening and closing windows to get back to the today screen also cause a problem. I've disabled TF3D to see if that makes a difference, it doesn't. I have a blank today screen with no plugins to free up the system resources, and am still having this issue.
I'm using JD's Rom (probably around 1.3, it's been running fine with no issues up to this point).
I'm also using S2U2 1.35 (if that makes any difference, haven't had any problems until recently)
The phone has never been dropped, it's in InvisibleShield, and normally sits on my desk charging all day.
This started happening last night for no apparent reason and it's really starting to irratate me.
Any advice is appreciated. Thanks.
Re the black screen:
Sounds like its software related. For example, I sometimes have this if I leave PocketTwit in the foreground and turn off phone. What software did you install yesterday? Also, do you try to press the home key and see if that clears the screen?
After more testing..
After some more fiddling around with the phone I'm about 90% certain it's a hardware issue. I noticed that when I slide the keyboard out if the slide portion is past the number line then the screen will stay on, but not update. I don't know how well I can explain it. If I'm typing and hold the screen to keep it from opening all the way then I can see the letters/words appear (in txt msg/email), but if I let the screen goes and it slides all the way open then the screen will stay on and only show what has already happened, any more typed characters will not appear, but if I move the screen back to the number row then the screen will re-draw and update what has happened.
Is this something that Sprint should fix no questions asked?

The last piece of software I installed was Gyrator 2 on Friday-ish. Thinking that it was the problem, I removed it using MemMaid. I'm going to give the phone a flash tonight and see if it is software related (hoping for the easy fix) but as the post above says, I'm almost certain it's a hardware issue. I just wish I knew how it happened. . . So much for that time putting those InvShld on.
Final Update (this can be closed)
I took it into a Sprint store and they replaced the "flip" on the top for free (I have insurance).
Point of the story/thread, this can be closed, it was a hardware issue, and now it's fixed.
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.
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.
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?
I have recorded a video that shows what I mean: https://www.youtube.com/watch?v=UW2gCWpThWc

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.
i think my phonne is fudged up, its in perfect conditon and has no cracks,neither did i drop the phone or anything.
yesterday all of a sudden my hardware buttons ( bottom 3 buttons), and the lower part of the screen stopped working completely,not even in twrp,meaning i cant swipe to flash there becuase its in the part of the screen that dosent work.
anyone has any idea what i can do? i tried disabling and enabling hardware buttons,and resetting of course.
is there anything i can flash through fastboot to maybe fix it? maybe touch firmware or something
pretty sure its a hardware problem though
it was very hot were i live,so i think maybe the heat ruined something inside the phone
Experiencing similar issues
I am having the same problem, though I think I am a little more fortunate than you in terms of the amount of the screen that is not responsive. For the timebeing, I turned on on-screen buttons and allowed a full 180 degree rotation, which allows the button functions to work if the screen is rotated. It at least makes the phone usable for now.
Any help would really be appreciated.
Cheers

I am having the same issue. I can't reflash anything as when I swipe in twrp, the bar only goes partway across the screen then just bounces back to the beginning. Been searching the web for hours trying to find a solution.
