Touch still unresponsive after digitizer replaced

About 2 weeks ago my touch function stopped responding. I was away from the night and it died shortly after and I did not have my charger. The next day once I got it charged up, I powered it on and was able to get a few minutes of working touch sense... then the touch died completely. I opened it up to make sure all of the cables were intact- Everything inside looked perfect except for the little latch that holds down on the digitizer cable was broken off, but that was already like that for a while and everything was still working.) After some fiddleing and no luck, I decided I probably just need to get a new digitizer--- It would be easy to disassemble because my lcd and digitizer were both oem from a drop in the potty a few minths back, which only affected the screen. So today the digitizer came in and I replaced it- NO LUCK! Every once in a while I get a tiny spark of scroll functionality or the bottom of the screen while in landscape mode becomes touchable for a few seconds, but otherwise dead.
Does anyone know what the problem could be since I have already replaced the digitizer???
Right now I am only able too hook up my internet sharing and etc. through MyMobiler.
Thanks

[Q] Advice on unlock/digitiser issue

Hi
I upgraded to my new DHD less than 3 weeks ago. It is not rooted and I did the recent OTA update over Christmas.
Over the last couple of days I have started to experience difficulty unlocking the device on the slide-to-unlock screen. The problem seems intermittent - somethimes it will unlock fine, and other times the slider just seems to "get stuck" at the bottom of the screen.
At first I thought this a bug or something, but after some investigation I am concerned there is a problem with the digitiser. I opened a picture and zoomed in to fill the screen and tested the touchscreen in different places by sliding the picture around. What I found was that the bottom 1cm of the screen above the keys does not respond properly to Up and Down swipes. It is fine however with side-to-side and also individual taps. This is obviously a problem when trying to move the unlock slider!
I've had a screen protector on for about a week - I don't imagine this has caused the issue but haven't removed it to test as yet as I don't have a spare. Aside from this, the device has been very well looked after, definitely no bumps etc and kept in an HTC leather pouch.
Any ideas? Should I return it to CW?
Thanks

OK, I seem to have resolved this for the time being but expect the problem to return.
I downloaded a screen test app that allows you to draw on the screen and got some very strange results. A 1cm band of screen about 1cm up from the bottom was completely unresponsive. Trying to draw a horizontal line within this band would result in lines being drawn either above or below it, or strange vertical lines "jumping" around. The rest of the screen was fine. I realised this is why I have been struggling to close the keyboard - the button is placed within this band and trying to press it would result in on of the buttons above or below being pressed. Also have had problems with the sapce bar.
I did a restart (not fast) and this has resolved the issue, however I expect it may return as I did a restart only yesterday.
At least it is obviously software and not the digitiser....

Hi again. As expected, the issue returned after a couple of hours. This time however, restarting is not making a difference.
I resorted to a hard rest, which has not changed anything either.
Any help/ideas would really be appreciated...

Best to return it for repairs or exchange. Seems like the digitiser is faulty.

I agree, this definitely sounds like a hardware problem.

Ghost touches

Anyone else getting the ghost touch problem?
I couldn't work out what was causing this on my phone so I enabled show touches in the development menu and it shows.
It goes from 2 to 3 spots on the left hand side of the screen.
It's not a major problem but happens at least 3 times a day and won't snap out of it unless I put the phone back into sleep a couple of times.
Do you think maybe scratches on the screen cause this?
TIA

Is your phone connected to a charger when this occurs? It might be it, since im experiencing the same thing since htc desire hd.

No. Can happen at anytime. Quite random.
It takes a few on and offs with the sleep button to stop it.
Can't get off the lock screen until it goes away because I can't move the unlock slider.
Very annoying.

I had the same problem - the first day i got my hox. With and without the charger (with charger a litte bit more often i think).
I pushed the complete left side of the screen (top) carefully and now it works well. No more ghost touches ^^.

Ok. Once I pushed around the screen edges, the left side has some play and moves maybe a mm with a slight creak.
I push it in but still that little bit of play on the left side.
It's quite impossible to show the service centre the problem because its so random but now I can show them this.
Cheers.

I hope you'll get a new "perfect" hox and i'll not have the same problem later :fingers-crossed:

Screen possessed the capacative buttons stop working

Brought a second hand p8000 couple days ago thinking it had screen flickering bug that you use Nova launcher to solve but turns out the digitizer is broken or loose I think. When I switch on it work fine but when I touch home or left capacative button they don't work.
After some minutes the home and left button start to work then all of a sudden the screen goes bezel and starts opening unrelated apps and pulling down status bar without me touching
The screen itself looks as though it's coming away from frame in middle section
I took apart last night and when I touch digitizer plug at top it also starts the bezerk reaction
Anyone have any ideas how to fix this? Is it just broken digitizer ribbon cable?
Thanks

In case anyone has same problem and found this through search.... I just wrapped sellotape around digitized cable as it was shorting out on frame

friend of mine has the same problem with p800. looking for some solution. just seen similar threads on official elephone forum, but no answer from elephone or some tips

Random Touch on the Screen.

I do not know whether this counts as ghost touch or not, but randomly there is a persistent touch on the bottom right corner of my Zenfone 2, ZE551ML. If i Lock the device and unlock it back again, (Through the power button), the issue goes away. It re appears after a while again.
I saw videos of people facing such issues on youtube, but in their cases, the entire touch automatically starts to act up. whereas in my case, this happens only if i start using the phone. And that too on the same area ( Bottom Right, Just over the Recents Button)
I wiped the screen / Scratch guard thoroughly. I even changed my scratch guard. but still the issue stays.
Im on Stock 183 (Not yet updated to 184).
Is this a hardware issue or a software one?
(My warranty just ended yesterday).
I feel this is software, because the touch works normally if i lock the device and then unlock it back.
Just for the record, my device passed the SMMI touch and multi touch test without issues.
Also i enabled the graph option under developer options. And i do not see any touch being registered under normal course.
But then when all the tools are off, randomly the issue just pops up again.
Does anyone have such issues?
Does CM or other Non-stock ROM solve this??

I actually a similar issue a month ago, which I thought was a software thing (completely wiped my phone, then installed latest XOSP) or me losing my mind, and it turns out it was neither.
It came back yesterday, and I learned that there's entirely a chance that the screen connectors are loose. Simply remove the back panel (the one with the screws, you'll need one of those eyeglass-repair screwdrivers) and press down on the connectors to make sure they're 100% snapped in and the issue should stop!
Also, see if Glove mode fixes it, since I know that works for a lot of people.

I had the problem. I just removed back cover and plugged a bit more the connectors that you can see when removing battery cover.
Its been 3 months without the problem.

Okay so
My issue is because of my flip cover.
I knew this wasn't hardware, coz the issue was only on one small area of the screen.
I did the following:
When there was ghost random touch.
I immediately removed my flip cover, and the issue went off
Did It twice, both times, it worked.
Thanks anyways.
