I dropped my XDA IIi, I've been luckier than many as the phone is fine, the only thing that isn't fine is that the touch screen and the LCD have become misaligned.
There's no problem with the majority of the screen because I just re-aligned it with the screen aligning software, but theres a 3mm or so are on the left of the screen that will not work due, I assume, to the screen slipping when dropped.
How easy is it to fix?

Recently I added a screen protector to my Alpine, and after that the screen started acting funny any time it was left alone. Removing the screen protector has made no difference.
After a short while of not being used, the screen becomes misaligned, for example if I leave it off for an hour, attempting to activate the start menu on the today screen will result in one of the today items being pushed, or attempting to select a number on the password entry will result in a different number being pressed.
The strange thing is I can re-align the screen through the control panel, but it will slowly go back to the way it was.
Anyone got any thoughts? At worst, I'll just refund it (I bought it where I work, and thats no problem) and get another handset, but if theres a fix I'd prefer to stick with my current handset.
Cheers in advance for any help!
I am not sure about this, but I had the same problem with Motorola A1000 touch screen - could it be that an excessive pressure was applied to one of the sides of the digitizer during the application of screen protector? The digitizer is glued on the LCD, there might be a remote chance that it has slid a little to one side. Also some extra glue could have shortened the contacts on the bottom part of the digitizer. I would try to clean it first with some anti-static liquid. Hope this helps..
Indeed, this sounds like there could be more pressure to one side of the screen than the other, hence the digitiser tries to adjust for the pressure difference and gradually falls out of sync.
Try reapplying your screen protector, more gently than last time if possible, but don't wipe from side to side, wipe from top to bottom with an even pressure. Also, try realigning the screen with the protector off before reapplying it.
I had a problem with my screen originally before I got my screen protector, insofar as I got that 'rainbow' pooling effect in the centre of the screen where the digitiser was touching the LCD layer - after about a week after application of the screen protector, however, the more even layer of tension provided by the protector somehow pulled the digitiser away from the LCD layer, so my screen has actually gotten better since then... That said, I could imagine that uneven tension on the top layer could lift the LCD and digitiser layers further away from each other on one side than on the other, causing the problem you describe here. If you can bear to, try using the phone for a couple of days without the protective top layer applied, and see if the alignment gradually slips out as it's doing at the moment.
I've been using the phone for the past two days without the protective cover on. I'm going to reapply it now and then see how it goes tomorrow. If its still screwed, I'll reflash it to the O2 ROM and refund it at work on Tuesday.
Got a replacement, so no problem now. Thanks for the help anyhow
I just replaced a screen in a Trinity (Dopod D810). The touchscreen initially wasn't calibrated correctly so I ran the alignment tool in the settings, and after a few attempts, I calibrated it properly and the touchscreen was working perfectly. Now the touchscreen is not working properly. The top half of the screen responds to touch, but no matter where I press in that region, the screen thinks I'm pressing the top-right corner. When I run the alignment again, it responds to all the touchpoints but it never successfully calibrates and it keeps bringing me back to the alignment screen.
The current settings in the registry entry for touch calibration are as follows:
484,558 244,286 263,815 750,820 707,295
I've found a few other threads here (the most helpful being http://forum.xda-developers.com/showthread.php?t=355010) and I've tried the settings from that thread. The screen seems more responsive, but still not correct because the bottom half hardly responds and the top half seems to respond when it feels like it.
Can someone please post their D810 touchscreen settings so I can try it? I've tried the settings from my Touch Cruise, but the screen is still doing weird things.
This is a customer's phone so I need to have this fixed ASAP.
I'm thinking that it may be a faulty digitizer, but that won't explain why it worked perfectly when I first calibrated it.
UPDATE: NOT FIXED yet, but now the backlight is dead. I just turned it off, and then turned it on again, but I can only see the screen content if I shine a torch onto the screen. The LCD hasn't leaked. The backlight just died and the connectors in the phone are fine. Perhaps this was a dodgy screen.
Any ideas?!
since the device has a recessed screen, take the cover off to get at it.
take a soft cloth or something and clean off all the garbage on the digitizer and back of the plastic. make sure everything around the lcd is free of dirt.
usually, if there is something pushing down on the digitizer while you calibrate it, it will totally bork the alignment over the course of 10 minutes to an hour.
my kaiser is currently having this issue, though i put it though alot more hell then i should have... so i suspect its suffering from other issues.
This is very odd...
My Diamond display have always been hard to touch in the edges of the display, I always needed to use the stylus and press quite hard for it to register a touch. The middle always needed just a slight touch.
Now I've just changed the screen protector and suddenly it's the middle of the display that requires me to press hard on the screen and the edges just need very little pressure.
Any ideas what happened? Did I damage something, I think this is very weird how a new screen protector (exactly the same brand) can change the display behavior this way...
maybe new screen protector is a little fatter
i have original protector and display have always been hard to touch in the edges of the display
my galaxy ace had dust under the screen. to remove it, i disassembled the phone. I removed the dust between the glass and the screen, assembled the phone again and booted it up. But know the phone does not respond to any touch.
to find out what the problem is i'd like to know how the screen works. I believe that when I touch the screen, this is sent from the front glass to the 'phone', which makes the screen show the according view. So when the screen does not respond to me touching the screen i'd have to look for a new glass or could there be another problem?
i''ve cleaned the screen with lcd screen cleaner (on both sides because there was a fingerprint on it on the back side). I don't know if there was some sort of layer on the glass which could be removed by this cleaner, which actually would be essential for the touch function.
i hope someone can help me. I'd like to use this ace for a longer time...

thanks! i've used that tutorial for replacing the broken screen my ace came with from my sister. I replaced it and then everything worked fine again. However ,after that screen replacement, there got dust under the screen which I tried to remove this afternoon.
The dust is gone, but the screen doens''t respond to anything now.
I'am wondering if i 'broke' the screen and I should get a replacement screen, or that i may have damaged the lcd screen (which is fine i think, it displays everthing perfectly). or maybe the glass is fine but some connector is defect (i've disassembled the phone again, checked everything and connected it again).
I replaced the screen on my phone a few weeks back and earlier today the screen was lifting so I removed it to re adhesive it. The screen was working perfectly fine before hand however now it is not giving a display signal. Me touching the screen still gives feedback but nothing on the display. The screen was on the same table as where I dismantled it. The screen had a bit of adhesive down the side of I used some 80% alcohol hand sanitiser to help remove it. Refit the screen and their is no display, been a fair few hours and still nothing. Swapped broken screen in and their is no display on that one either, Pls advise what could be the issue and how I could recover data as there is a password on the device.
