Hi guys, I have been having an issue with my i9305 where a touch point seems to stick and my phone won't respond properly to other touch Input, sometimes looks like it's having a bit of a fit, it's as if I'm holding a finger down on one point. I have broken the screen a couple of times and replaced it but most of the time it works flawlessly, it seems a lot like a software or driver issue, happens exactly the same across all roms, long pressing seems to set it off the most, stays stuck unti I Switch my screen off and on and unlock it's fine again, can happen every few seconds or might not happen all day, any thoughts?
You say you have broken and replaced your screen twice, which is very unusual, so are you sure you didn't drop your phone since the last screen replacement? Also, did you take the phone to an authorised service center or did you replace the screen yourself, with parts that you acquired? Maybe you have a faulty screen that needs replacement once again.

The screen has been cracked slightly in my pocket twice, only ever a crack, not smashed or anything, don't know what happened the first time but the second time I tried to pick something up and it leaned against my phone in my pocket and cracked the screen, I have replaced the glass myself twice, only light heat and gentle separation, replaced with glass and adhesive membrane like original, the digitiser seems completely untouched. It probably is something to do with the digitiser or screen, I just wanted to see if it is happening to anyone else before I fork out for a new digitiser, would be more cost effective to just buy a new phone. Just seems like a software or firmware thing by the way it acts and is fine after a quick on off of the screen, as if there is some cache for the touch control that gets cleared when I Switch the screen of, dunno.

so, i just got this phone about a week ago, and its already seen several near death experiences with all the flashing ive been doing. but this one takes the cake. all i did was put the phone in my back pocket, with the screen facing in, sat down for half a second, and when i took it out, the screen had been pressed so hard that the top layer of the resistive screen was stuck to the bottm, and not registering anything. i knew the first step to fixing it was getting it unstuck. but it still wounldnt work. did a hard reset. and now im stuck at my initial tap screen to set up phone screen, and i cant do anything. this is clearly a hardware problem. can anyone help me out?
lemme be the first to say it man, ouch lol
sorry about your screen, i fear the only way to fix would be to find another screen assembly, if you search the threads for the cdma raphael(herman) i beleive there is a detailed teardown of the phone that may or may not help you resolve your problem. here is a quick link to something along the lines of what your looking for but not really too detailed : http://www.ifixit.com/Teardown/HTC-Touch-Pro/787/1
ive done that, but usually break the screen completely. i have an extra us cellular tp that has a bad keyboard and front panel buttons but screen and touch works. i just use it as a extra battery charger. has some scratches, but works. ill send it to you if you send me your old one. the screen has a double-stick tape that holds it to the frame around the edges. let me know if your able to tear it down and think you can put it back together again. its a pretty straight forward process though.
Apply packing tape to the screen and pull as hard as you can.
HTC legend. Screen behave very strangely.
When you turn phone on its kind a OK, but in some time strange things happen.
Some parts of screen are unresponding. Or for example if you slide at the bottom of the screen it acts as if you pull status bar down.
Some times every touch tries to pull status bar down. But then again it will be normal.
Is that a hardware or software problem.
I tried hard reset too, didnt help. So is it screen itself then?
I would change it, but still not sure about it. Why its not bad all the time?
Thanks for all the help.
Search for TouchRecalibrate in Market maybe that helps.

hardware i'm afraid.
had the same problem after my phone got wet along with me in bat-****-crazy storm.
you don't need to replace the lcd, just the digitizer.
i picked one up off ebay for £10.
the replacement process is kinda scary in places - mainly prising the digitizer off the lcd.
if you're still under warranty and the damage wasn't obviously caused by yourself (that includes getting water inside the casing - the water residue gives it away unfortunately) i'd flash back to stock and rma it.
Well I thought it will be digitizer too.
Already ordered one. And yes, my missus dropped it in to a toilet after just 2 months since she bought it new. Just didn't had time to get to it till now. And warranty doesn't apply for this
She should have bough same like me - Defy
So my HTC Desire Z, running CM7, has recently started acting up. There is a certain spot on my touch screen that, at random times, will act as if it's been touched. In GO SMS PRO, this occasionally lines up with a message, so I can see it press, pause, press, pause, etc. It's really annoying and screws up my usage of the phone. If I turn the screen off and then on again, it'll usually go away for a bit.
I've tried googling this issue but it's a touchy thing to phrase. (hehe, "touchy", I didn't even mean to do that!)
Does anybody know how I can find out what is causing this and/or how to fix it?
tl;dr: touch screen is "pressing" a specific spot at random

Its not rocket science is it bro ......... i figure you already can see the writing on the wall ...... sounds like your digitiser is on its way out. Quite a common issue on HTC's the capacitive touch screens just wear out.
My advice is backup, do a factory reset. see if problem persists, if so maybe try a different ROM (just for the sake of testing) see if problem persists.
If so you know its a hardware fault.
The good news is its really pretty easy to replace a digitiser in a Desire Z, I bought my own Desire Z 2nd hand with a dodgy digitiser (for about half its 2nd hand value) and replaced the digitiser in about 3 hours (that was going very slowly and being very careful)
Here is a link to the disassembly guides i used

Desire Z is one of the easiest phones i have ever worked on HTC obviously designed it to be repairable, almost everything is held by screws. So you don't have to 'unclip' loads of weak plastic crap.
All you need is to take it sloooooooowly and NEVER use much force, better to take an hour to do a job that should take 10mins than to rush or get impatient and break sh*t.
Good luck

Update: So the "pressing" isn't really happening any more, but now there's a dead area that takes up an entire horizontal portion of the screen. I tested it out using a TouchTest app (picture 1) and the cut shows the dead portion. However, I tried it again later, and the dead portion moved up! I'm very confused, haha
Hello everyone, I'd just like to share something that happened with my HOX+.
Earlier today my touchscreen acted up and was getting random touch input on a particular portion of the screen. Thinking it may have just been something on the screen like oil or whatever, I just gave it a quick wipe and it went back to normal.
Now a while ago, that particular portion of the touch screen totally died on me. I didn't think it was a software problem because I didn't flash anything or install any app from the play store. Also, that portion(about a half inch strip from the top of the phone when held in portrait edge to edge, left to right) wasn't working even in recovery(CWM).
So I searched the net for similar accounts and found put that it may be a faulty digitizer. While I do have official HTC warranty, claims in our country(Philippines) usually take forever if you get past all the retailer and distributor bullcrap at all.
Luckily, I happened upon a single post somewhere where this person just pressed hard on the unresponsive portion of his touchscreen(different device) for a few seconds and the problem went away. Fortunately it also worked for me.
Just sharing my experience just in case this also happens to someone else. For now I'm hoping the problem does not reoccur. I've also secured my Proof of Purchase to be sure.

EDIT: Based on the fact that I could now pull down the notification bar, I assumed the whole screen was now OK. But now it seems there is still a narrow strip which is unresponsive. I'm now starting to think this was caused by the pouch I had been using which had a clasp corresponding to that location in combination with the long time it had been placed in a tight pants pocket earlier today.

Hi guys,
Going to pick my Mum`s phone up from Vodafone today after it was placed in for repair and they stated it`ll be £150 to repair. She took it in as the phone started to bootloop, Samsung screen the reboot. She took it into Vodafone and they sent it off, the answer back was that the "chip behind the screen" was damaged and that was her fault and would cost £150 to repair.
Couple of question, what is the "chip behind the screen"?
If the chip is there what does it do and would it stop the phone from booting?
Is it repairable and if so could it be done at home cheaper?
Should I try a Samsung Service Center instead?
She said that she was having issues with the phone before it died, sluggishness, unresponsiveness and random reboots, then dead.
Cheers in advance guys,
Blinky
"Chip behind the screen" doesn't really mean much. I would ask them to be explicit. Since the screen covers 90% of the front of the phone, almost all the chips the phone has are behind the screen.
Sorry, I have just been informed that she was told it was the chip that controls the LCD screen? I would presume that if the touchscreen chip is dead then the phone would boot to the OS and you wouldn`t be able to control it and if the chip was good and the screen was knackered then you would not see the screen come on.
If the phone is stuck in a bootloop then wouldn`t that be a system board problem?
cheers
Blinky
yes

Well hang on.....
Its an SAMOLED not LCD, but thats not the main thing I need to identify here. Just FYI, the SAMOLED screen (Display Panel) and the touchscreen, although on this phone, mostly provided in a single unit - are actually 2 individual parts. You do not touch the display panel to get touch input.
Essentially from the outside in, you have:
1) Gorilla glass tough glass protector
2) Digitiser film (to translate electrical disturbances into input)
3) SAMOLED Panel (Display)
I don't really understand what chips control what so what VF are saying still seems ambiguous to me.
But a hardware failure could be picked up by the kernel drivers at boot. The kernel would see an error and a boot loop could ensue, definitely. It just depends on the fault.
