My Dear friends, I got a Xperia XA Ultra from a friend, display was damaged. So I purchased a New Display with Touch from a Local Shop, but i noticed touch is not working properly, ghost touch on top and bottom of the display. Then i went to the shop and asked for a replacement LCD and they gave me another new LCD. I checked the lcd at shop with the sony *#*#service#*#* code.. and all the touch screen tests were Pass. But after i came back to home and used the phone for 2, 3 hours and again suddenly ghost touch started on top, bottom.
Anybody had same issue like me??? If yes, what is the solution????
Also i want to know Is there any Touch control IC or chip on the phone Motherboard that cause ghost touch????
Please help me regarding this issue.
Thank you.
bump.. anyone???

Good Day folks, here is the long and short of it.
Galaxy s 2 fell and the screen broke
I bought a new screen
Replaced the screen BUT two big problems occured.
1. The screen appears to have less colours than my original screen
2. NONE OF THE SOFT KEYS WORK, HOME, MENU AND BACK DO NOT WORK.
Number 2. is the big problem. Does anyone have any idea how these buttons work?
Even when I press the buttons directly with my fingers with the buttons off they still do not work.
Im baffled. Please help.
I also have attached pictures of the button area
It happened to me, I removed the screen, I replaced from beginning and it worked...
Hi Collado, do the white things behind the buttons have any electronic functionality or are those just things to make it stick?
To all future readers. I found out what the problem was. Basically,
The home, back and menu keys are all connected to a single ribbon. It appears there is a tiny piece, connected via the back key. That was torn while i was ripping off the the screen and digitizer.
See the picture attached
How much did you pay for your replacement screen and where did you get it. My digitizer is broken due to a drop. My front glass is perfect but the digitizer is completey shot. How difficult was this project?
Hi Johnboy
I cant remember the price of the digitizer offhand but make a check on ebay.. that is where i got it.
Difficulty is high as you need the minature tool set to do this effectively and a gentle touch.
However, it still appears as though the screen I bought has less colours.
Sorry to jump in and unintended hijack
I also dropped my S2 and cracked the screen, and after checking around dropped it in to the Geek Squad at CPW. Who duly replaced the screen and digitizer for £80. Only problem is the screen seems less bright and if moved off the central viewing angle the screen dims, as if it wasa standard lcd and not the orginal AMOLED screen. Does anyone know if they make lesser screens or was it fitted badly.
Any advice greatly appreciated.

I would go back with it and complain.If you dont get satisfaction then do an impression of the guy that goes into the pizza shop in "rise of the foot-soldier" film.

Hi, I have an Atrix 4g, great phone, by accident hit the screen with a corner an since then the touch start to fail in some spots, de screen was intact, I buy another digitizer on ebay and installed but the new one still have some touch dead spots, I need know if cant be other cause for the failure of the touchscreen in some areas, or maybe the new digitizer was installed wrong or come faulty. Really want fix this phone.
hey fellow modders,
i recently dropped my legend on a trek resulting in a cracked digitizer and screen. for replacement i was looking for cheap broken legends on ebay to replace the broken screen and digitizer and came across two items which say
"ALTHOUGH THE PHONE DOES SEND & RECEIVE CALLS
THE TOUCH SCREEN FOR THE DROP DOWN BOXES SOMETIMES
WORKS & SOMETIMES DOESNT, HENCE SPARES OR REPAIR."
if the digitizer and screen is sourced from such a phone will my perfect (was perfect before it was dropped) legend also inherit the mentioned problem?? apparently this is a common problem with legends.
Thanks very much and mod on XDA!!
Hi,
I cracked the screen on the Sony Xperia Z ultra. I bought an LCD screen and touch screen separately. I have installed both the lcd and the touch screen digitizer very carefully and correctly.
The lcd screen works fine however I cannot get the touch screen to work. There is no response to touches. I have not bonded them together or placed any tape between them. Is it possible the touch screen is faulty or does it have to be bonded to the lcd screen? What I am missing here.
Thanks,
Rob

Hi after trying everything with hardware and running out of options I decided to flash the stock rom again just to see what happens. When I booted everything worked. The touch screen behaves normally now. I guess some software must have been corrupted. It may not be necessary to flash the rom again, it may just require a factory reset. I didn't try this but it may suffice.
I hope this helps someone.

Hi All,
Here is the issue. xperia z3 |compact needed a new screen after a fight with a car. I bought replacement and installed. However, although the image is good and the digitizer responsive, if I touch the screen centre ('show touch' is on) the touch and screen response line up but further out from the centre, the more out of alignment the touch and response is. It is as if the 4.6 inch digitizer has 4.3 inch firmware in it. Have factory reset and tried calibration apps. Is there a way to tweak this, perhaps by an Input Device Configuration file (*.idc) or to force Android to change the touch position via an app?
I very carefully installed this screen to be waterproof, so I am loathe to start again with a new screen if I can avoid it.
Any help most welcome
