Hi Defy community,
I am having a strange issue with my defy mb525(bayer module). Sometimes just randomly the touch screen detects touches that aren't physically taking place(screen ghosting). It makes the phone useless and I have to pull out the battery in order to get my phone to behave again. Is there any solution to this problem? Is it a fault with the screen? What should I do? PLEASE HELP ME!!!!
If you have a screen protector remove it.
Another solution is to clean the display with an LCD cleaning spray.
If all of this is not working then your display is broken.

Thanks. I have no screen protector, but I'll try the cleaning solution.

I always had it, because my hand sweats a lot, so the defy feels like its being touched at the spot where a little sweat was on screen.
Just turn the screen off and clean it, then turn it on, it will work great
A screen protector helps a lot, just a hint

The screen on my xda exec stopped responding to taps. It seems that the touch screen ability is gone. I can use the keyboard fine and I've done a hard reset. Does anybody have any ideas on how to fix this?
Thanks.
I had the same problem, send it for repair. And the same problem reappeared 2 weeks later.
So I tried to find out what the problem was and thanks to this post I solved the problem;

It's not really that weird: If some dust, or something equally small gets between the screen and the plastic frame, it can put enough pressure on the screen, and so the touch screen takes it as a constant (or intermitent) input, invalidating any other action on the rest of the screen.
And this is exactly what happens, try to clean with a thin paper between the plastic frame and the screen.
It solved all my problems, now every once in a while I get the problem and once cleaned it works again perfectly.

Thanks. I'll try that. Fingers crossed!
The cleaning did not cure it. Took it to a repair shop. They said the LCD and touch screen are fine. When he tinkered with the flex cable (disconnect and reconnect), it will work for a few minutes and stop. Does anybody know where I can get this specific part? Is it really the cause of the problem?

Unfortunately this sounds like the heat related alignment problem. When the device gets warm e.g when using wifi or charging say when connected to Active Sync, the heat causes a small internal expansion. This puts pressure on the edges of the touch sensitive screen.
If you have a warranty, use it, because there is no guaranteed fix.
If you don't have a warranty then the Wiki here outlines the things to try. Essentially for you I think it would be to unscrew by one quarter turn, the two screws on the back of the screen. Secondly, the business card trick of running the corner of the card between the screen edge and the bezel of the casing. There is a thin rubber gasket in there and the card can be used to free up a bit of room. This may cause small rubber granules to come free. Don't leave a lumpy mess of granules in there though. Best clear it right out. This is a warranty voiding procedure!!
Replacing the LCD is not likely to improve matters as actually the screen is probably fine, It's the pressure being put on it!

Well, as I said above it sounds heat related and there is no fix other than the things you have tried - you need a replacement. Someone on this board ended up keeping the device in the fridge so they could get half an hour from it before it conked out again. It's a replacement job IMHO.

I check temperature by BatteryStatus tool is : 45.7C (temperature is normal or not).
What is gets warm, CPU, VGA...
I think LCD hots not influence touch sensitive screen, becausse lastime I use XDA IIS device very host when use wifi but screen no problem.
Hi, ive experienced two issues with my Touch HD, one of them is that the phone calls get disconnected at a random time. I can talk for 5 minutes and suddenly the phone shuts down the call... And the other issue is with the screen, wich is demonstrated on the attached picture. It comes and goes, so its not persistant but it looks really bad on the screen when its there. The attached picture is coming from a Diamond, and it looks exactly like the problem I have on my Touch HD.
Can anyone confirm this and perhaps come up with a solution?
Thanks
Hello
If you have the protection foil adhesed to your screen it could definitely be that...
Consider that your device heats up when charging or while you do lot of stuff with it - hardware heats up and the glue or whatever it is comes off so your foil does the same
My friend had the foil on but got really fed with it so he just took it off and no more stuff like that on your screen...
If you do not have this foil it is probably a HW issue with your screen thus you should get it replaced - whole device of course....
hope I helped...
about random dropping the calls there are several discusiions around. just use search option!
hint:
try to change settings-phone-band-network type from auto to just gsm
3g is known as often drop the quality and maybe your phone try to switch from 3g to gsm.
if this is not the situation, look around, maybe someone found the solution
about the rainbow stain, could it be just moisture caused by moving from cold temperature to warm temperature?
is it still there if your phone is out in cold air? did you noticed if the stain is always there or it occurs only when the phone became hot?
if this is the situation, you have to remove the shield from screen and install it (or a new one) again but on a dry screen.
if you don't have a screen protector, then your problem is more complicated as the moisture is between your screen layers and can be changed only at a htc service center
I also read somwhere (forgot where) that the rainbow stain can be caused by pressure
yours is a very neat rectangle
does it always appear in the same place ?
when the pressure releases later it can then vanish
this is the link, it also explains how to solve the stain issue

Zesper, thanks for the link.. this is the issue with my Touch HD. Its now shipped for repair and I hope the warranty will cover it. The funny thing here is that the problem comes and goes.
Regarding the dropping calls, ill try with the switch to gsm, once its back again from repair.
Thanks
Hey Guys, Can anyone help ?
I plugged my phone in to charge overnight like normal and when i unplugged it next morning the screen will not respond to taps. There are no cracks or damage to the screen and it hasnt had a bump.
A hard reset gets me as far as the calibration screen but again, cant do it.
Does anyone either have any ideas or can anyone recommend a good repair place in the uk ??
thanks.
Andy

Hi Andy,
If you are familiar with rom flashing you could try it before sending to repair in case it's software related.
Good luck
Arrrrrrggghhh-bloody backlight/touch bricked!
I have the same issue and it's driving me nuts!!
pressing the screen bottom left quite hard puts the backlight back on but it goes off as soon as I take my finger off.
Having done a web search, it appears that this may be a firmware issue, but if so, why, after 9 months of trouble free use, has it only just happened?
I'd be very interested if anyone else has solved this issue. Is there patch or is it a hardware issue?
My otherwise excellent touch is effectively bricked-any help or suggestions at all would be appreciated!
A fix (sort of)
I bit the bullet and ordered a replacement LCD module online and fitted it. It worked, proving that there was indeed an issue with the original. Problem is, the quality of the new one is really bad so DON'T buy a replacement online is my advice. I've now sent my beloved Touch back to HTC to get it fixed...
Hopefully I'll have it back and working soon.
FIXED !
i know this is gonna sound weird but i bought a BENQ_E72 while my touch wasnt working and i kinda forgot about the touch in the meantime. Yesterday i came back to the touch and lo and behold its working perfectly. Screen align is working, taps are going through and i cant see a problem.
Now i have read a thread about the Digitizer filling up with dust and yes my front case does have 2 hairline cracks in it so i am thinking a strip apart, new case and clean and go from there if it does it again. Odd how leaving it to discharge compleely for a couple of months has 'cured' the problem
Just thought i would share this with you

Hello, I have a Motorola Defy, that I dropped a few times, so the LCD screen got damaged with blue dots on it, I made a mistake and thought that the problem was on the touch Screen, so I purchased a replacement, installed but, it was damaged, the touch did not respond correctly, I wasn't able to type correctly among other problems.
I got a refund, then ordered a LCD screen replacement, now that I have it here, I install it, and it's broken:crying: I know, bad luck and being a rookie while trying to fix my phone, ok, I put back my old (damaged) LCD screen to use it in the meantime, and the old touch screen, but now, the old touch screen that was supposed to being working fine, it doesn't, it has the same problem as the touch screen that I bought.
Question is: the problem with the touch screen, could be related to the damaged LCD screen? or the motherboard of the phone is damaged? the phone works great, the apps, the games, everything but the touch screen and the LCD screen, but, as I said, I went back to the default touch screen after using the damaged one that I received, and it works worse I don't know what's wrong, please help me out, sorry for the long post
Please post questions in the Q&A section. Moved there.

Is this true?
true. fix some minor dead pixel if you put in freezer for one day. but your case... im dont hope much.
Try changing LCD + Capacitive Digitizer. (after trying the freezer trick ofcourse)
Well i will tell my story, which is related to your's as well,
i had a phone with resistive touch screen and it got screwed up, that is it does not respond correctly. So, i took it to the service center and they replaced the digitizer (touch screen) saying that previous one is broken. But, luckily the new one didn't responded to any touches they make.So, they replaced it again with the old one quoting that "your phone can't be repaired". So, i took it home with me.
Later i thought to calibrate the screen but the old one is not responding any more, no matter where i press
Later i calibrate it with the help of a software for windows mobile with the help of a PC. It took me to the calibration screen, from where i calibrated it, and voila, it worked... as good as a new one :victory:
long story short,
i think when you disconnected your digitizer, phones default values/drivers got messed up and are unable to find the new or the old digitizer you connect. I suggest you to go to the service center as these screens can not be calibrated.
Is there NO WAY at all to recalibrate the screen from the phone itself? or using an application? the delicalibration might be the problem....I'd like to fix it myself :/ thanks for the tip, never heard about it before!!

I replaced my original digitizer screen for the one I ordered it, it gave me problems, so I went back to the original one, which was working fine, and now it's not fully responding, that's why I'm assuming is something calibration related, thanks!
