[Q] Touch Screen Problem

Recently I began to notice a problem with my phone. Whenever I have the keyboard slid out the touch screen is almost non-responsive. So over the past few days I've tried observing what the exact problem is and I think it could be the cable/ribbon that connects the touch screen to the keyboard. I'll have to tilt the screen back and forth before it will actually recognize me touching it. And I've noticed when I rub that ribbon it seems to work. There's also a crease in the ribbon where it folds on it when you close it. I believe this is the problem but I'm not sure and I want any advice/tips I can get. If it is the cable can you order a new one and replace it yourself?
Thanks in advance

Any ideas anyone? I cant get it to half work so I can text and stuff but I have to press it hard and it still wont work at times so something somewhere or another is wrong.

Flash the stock ROM and SPL, and do a warranty exchange. This isn't a device you want to open up unless you really know what you're doing and are certain of the issue. If you really want to give it a go, then just buy a non-functioning unit from eBay to use for parts. They can normally be had for less than $40.

Wow, I cant believe that I finally found someone with the same problem as I have.
At first I thought that it was a software issue and I reloaded the software on my device.
The screen responds to presses with the keyboard in, but extended it doesnt respond and only the external keyboard works.
So to type a nice long sms I would have to start it on my display, flick out the keyboard to carry on and then flick it back in before I could press send or anything.
How frustrating.
But I did a test now and flicking the keyboard out and then slowly slowly pushing it back in I can get to a stage where both the external keyboard and screen responds at the same time again.
Definitely a ribbon problem or something.
Only had this phone for a few months now and if it already doing this then I am not feeling too obtimistic about its future.
Well, time to take it in for a warranty repair. I wonder how much greaf I am in for now.
Time to pull out my awesome trusty Artemis out the cuboard.

I had a friend that had this problem with his TP2 which I've successfully repaired. First thing if you want to do it yourself, go to youtube and look for the Rhodium disassembly video (this will help you a lot). It is not difficult to change any parts in the phone provided that you proceed with caution and take the necessary precautions.
If you are afraid or have never opened up a phone to fix parts, then I would suggest to send it to HTC - this would be devastating if you managed to break up the motherboard by mistake or any other parts in the process of fixing the flex cable.

Tripp --
Did you ever find resolution to your problem? Recently my phone started having the same problem, which I originally thought was related to messing up the calibration file when I put loaded xdandroid GBX0A.
However, it sounds like my problem is pretty similar to yours -- touchscreen works fine when the keyboard is closed, but when it is open it only registers on the bottom of the screen -- which is actually useful in some sense because I can still hit the soft keys in the messaging app and such, but not so useful if you want to scroll using the touch screen. If I play around with the z-hinge a bit, sometimes it starts working -- which sounds like the same thing that you described.

Sorry, I just seen your post but I never fixed mine as I went ahead and bought another phone (Evo) but I did research the problem quite extensively and the problem I believe lies in the ribbon that connects the two halves of the phone. If I remember correctly the motherboard is in the side with the keyboard and that's why when it's slide out, the touch screen won't respond correctly. You can find the part online and replace it yourself. I've taken mine apart and it's not that hard but as said, you need the right tools and to be very careful.

Hi guys
I have tried all the above
Last resort is i got sprite backyup to work
BUT HOW THE HELL DO YOU HIT "NEXT" OR "OK" FROM THE KEYBOARD AS SCREEN DOESNT WORK????

[Q] Dysfunctional Touch Screen

Recently, my touchscreen has been either registering random presses about 2/3 of the way up the screen, not registering touches at all, or registering double touches wherever I touch. Before I bring this in, any ideas on something to try? I cannot remember anything that would have caused it like drops or water damage.
Note: My phone is rooted, but I have tried different roms and kernels to make sure that wasn't the issue.

menu from the home screen...settings...language and keyboard...touch input...text input...calibration tool.

You can download Dotty from the market, not the game one. That will let you know exactly where the problem area(s) is(are). The right edge of my screen messed with me for some time before finally not working at all. It would cause all sorts of funky keyboard mistypes, repeated letters and such. Sent it to HTC last thursday, they replaced the screen and I should have it back by the 20th. Covered by warranty so no charge too! I believe my digitizer went bad?
Could also just be a widget causing the problem as I've heard they can somehow screw with the touch input. Faulty digitzers don't seem to be too common...

I should have mentioned that I did the screen calibration, but thanks for that tip. Well I used Dotty and Screen Test and they both confirmed the issue, so I sent it in. Thanks for the help.

Phone Broken?

My phone can't seem to work anymore if I slide it out. Everything just freezes, but if I tilt the screen up it works. Has anyone else had this problem before?

Well now the thing just freezes if the keyboard is out at all. I'm guessing it's a paperweight now?

A potential solution

Okay, I've just had this problem with an HTC Touch, and I think this works with any HTC that has a "digitizer" rather than an all-in-one touchscreen (I think newer phones have digitisers).
I'm not sure if this will always work, but I've just done it - sometimes the inactive touch screen is "broken" because the layers are stuck together (so the phone can't tell where the touch is, hence unresponsive). With mine, I looked at the screen side on and could see a kind of "oily" patch in the light.
The solution is to get masking/gaffa tape - the very sticky brown one. Stick it down on the screen/digitizer and then keep pulling it off - this pulls the layers from each other. I kept repeating this lots before it worked - and in the end I pulled the top layer completely off (I think you should pull from the top of the phone, as the layers need to be attached at the bottom of the screen/digitizer). Once it pulled away, I gently lay it back down (after panicking!!) and hey presto it started working again.
Good luck!

that sucks. might be a ROM things IDK

[Q]Gnex touch issue

Hello guys my gnex started to behave weird. Whole LCD and digitizer is working, touch sensitive, but sometimes it starts to make 2-3 touch points on screen just by it self. I tried tp reflash it via odin, without any success, it still does the same.
Now i don't know if it's HW or SW issue, because digitizer looks ok. Any idea?

my pixel c gone mad

Hi all,
I've recently got this tablet from Google store (and out of stock now).
After installed all things needed, a serious problem has appeared during in use. Its screen unexpectly trembles, pops notification out, runs and closes apps randomly then unable touchscreen at all. These make me crazy even in screen saver, and power button doesn't work sometimes to stop those happenings.
The device hasn't rooted and staying as 'pure' with only afew apps, so I've done erasing system cache partition on recovery mode and factory reset twice to solve this problem.
Nothing happened so far since reset the device but is still unsettling.. and now I just supposed touching screen badly (with sweaty fingers for example) or the screen protect film I affixed since unboxing might cause the problem.
Does anyone faces a problem like this?
Regards,
Allen

If it was greasy fingers my tablet would be completely unusable. Luckily a quick clean sorts any issues that causes.
My first suspicion would be the screen protector, as mine has done similar when there was something touching the screen. Maybe try taking it off and seeing how it goes? You can also turn on show taps in the Developer Options to be able to see what touches the tablet is detecting when it goes mad.

Better than before

Thanks for your reply. Now I've used a BT mouse to match with mine and less touch on the screen apparently. Nothing happened so far.
It's not a problem of hardware I supposed and pretty sure that the screen protector interferes a certain touch as you commented. Still my eyes are keeping on what caused the problem.
