Hi all,
I work for a company that has a lot of HTC touch2 phones. We've had a lot come back recently with similar 'unexplained' damage to the screens which stops the touchscreen part from working. The screen itself seems fine though. I've taken a picture one and attached it.
Does anyone have any idea what might cause this? I'm presuming just screen pressure but it'd be nice to be sure
Cheers
Louis
It's showing the "oily smear" issue which seems quite common with HTC's resistive touchscreens. I have a problem with it on my Touch Pro, although the touchscreen is generally usable - it sometimes requires some rubbing to "unstick" the layers of the touchscreen before it works though. When it first happened, the screen didn't work at all.

It seems to be related to excess pressure, but it's pretty common it seems. Mine was just in its T-Mobile provided case in my pocket when it happened.
Hello,
I've recently been given a Galaxy S3 phone. The phone has preciously been dropped in from what i understand it some water. Now the thing is. The phone's touchscreen is broken as in the touch doesn't work. the LCD however works so you can clearly see the image. Now for the rest the phone works. When you charge it up and start it. It functions properly loads up the operating system even the alarms work well i can't really press anything since the touch is fried but everything else looks good. So now i am about to order a touch screen + lcd replacement for it, including a backplate since it's kind of bruised. My question is what is your opinion of this.
The phone has previous been taken to a store where they demanded 300 euro to fix it under the condition that the touch screen was broken. So it has been researched from what i assume were professionals.
Before you ask i have plenty of knowledge with repairing fixing delicate computer equipment i have no knowledge of how to change a screen however plenty of online videos about it and it doesn't really look that difficult. Now my question is do you think the phone would work if i am to change the LCD + Touch.
Hello, firstly I apologize for my English. I have a Chinese phone Jiayu G2S for over a year, but since few months touchscreen isn't working well. Sensitivity is good and when I have totally dry fingers, all is ok. But when I have it slightly wet, then i can't do anything! When I am clicking on keyboard, then there is "ghost touch" at top of screen, which cause closing keyboard. I was wondering what might be the problem and I thought about my hot baths in a tub with surfing the net. Maybe because of that, moisure get inside a phone? Replacing touchscreen is cheap, but I want know, could it be problem with touchscreen or motherboard?
Problem same like in this video: youtube.com/watch?v=hlSMSQCQWtw
Where , do I find info on MTK6582 "ghost touch" problem ?
I have a generic Made in China Phone with no name, just C8000 and seems to be based on MTK6582 design, 5.5 inch screen.
Every repair shop says for Galaxy/apple they just replace the digitiser, but they won't touch a generic phone, cos they say they don't have the parts.
I switch trace on and the screen part which has the camera behine it has a continual ghost touch.
deactivating that part of the screen would fix the problem.
The problem is harware as it gradually got worse bit by bit.
for similar devices it seems to be a problem with screening of the touchscreen cable, as if touches the case.

Good day !
Hello, guys.
Recently, I dropped my M2 on the street, resulting in cracked touchscreen and lcd. Replaced both the touch and the lcd, everything seemed normal until I noticed that the middle part of the touch (a line going from the left to the right, around 1cm height) doesn't work, it just doesn't respond. Later, I got another new touchscreen and same story - same part of the screen doesn't work.
Maybe we have some kind of defect touch screens here in Bulgarian stores? Though I bought the two touches from two seperate stores. Or it's possible that it's something with the lcd? Even though it works normally, no strange behavior, no black spots, scratches or anything. Or could it be a software problem? Using Android 5.0.
Thanks in advance.
More likely to be motherboard problem if it's the same with 2 different screens being installed
Thanks for your answer.
One thing I forgot to mention - when testing the screen in Sony's Sketch app or in the service menu, if I run my finger from the top to the bottom, or the opposite way quickly, sometimes, the lines my finger makes don't get cut, i.e. it's like the screen is functioning properly, with no dead spots. What does this mean?
According to Sony support, it could be a compatibility issue between the phone/touchscreen/LCD, what do you think?
