[Q] Touchscreen not responding

So for some reason, the last few days the touchscreen on my phone was being super slow, and id have to turn off the screen, then turn it back on multiple times and keep trying to slide it to unlock. I dont know how this started. Ive been using the NexusHD2-Gingerbread V2.9.
Ive tried other ROMs and restored previous backups and nothing is working. The screen is still not responsive. Ive never had this happen before and not sure what else to do. Its just stuck on the lock screen but everything is unresponsive....any ideas???

Unfortunately, your touchscreen digitizer is dying. This is related to the hardkey malfunction. The only thing you can so now is flash back to stock WM Tom and send it back for repair. The phone's touchscreen need to be replaced.
Good luck,

Yeah thats what ive been reading, and right after i started this thread i was reading on another and read that you can fix it if you hold the power button down firmly (apparently the digitzier is right behind it)....that worked for me.
I think too much flashing and changing ROMS using the power button didnt help hehehe

Try using zMooth or Button Savior. This help your hardkey a lot. Since I have zMooth and Button Savior install on my phone, I no longer have to use the hardkey.

!!!!! FIND SOLUTION !!!!!
The digitiZer is under the hangup button. press the button bit hard till it nudges the digitiser a little. it worked for me.
(found it from : http://www.htcphones.net/htc-hd2-problems-with-touchscreen/ )
I'm so cool now!!

I have been living on this solution for almost 2 months now.
However I can't take it anymore not because I am lazy!
but because when sometimes you need to make a quick call or grab that
camera instantly I tend to waste a good 5 minutes trying to make that hardpress on the end key work with the digitizer cable.
My question is, would changing the digitizer work? or is it something else?
Ever noticed that T-Mobile HD2 has soldered digitizer connection to the LCD vs. flex-cable socket in standard Leo?

Back button less responsive

Hi guys,
I'm not sure if there has been a thread about this already but I can't search the forum properly right now.
Anyway, lately I'm getting slightly annoyed by the back button on my sgs2 it seems to be less responsive and sonehow smaller than the menu key. Also it feels like I have to put more pressure on it. I'm currently on kg3 and I'm not sure if I had this problem before. A quick google search showed me I'm not the only one with this problem.
Could this be a software problem or is this more of a hardware problem?
Anyone else got this ?

I've got this too. I thought it was my imagination!

Same here bro, and i just got my phone 2 days ago. I even had the problem that sometime it will double click even when i just press once. I'm thinking of sending the phone back to Samsung to check, but i have already rooted my phone so I'll have to wait until I get the USB Jig to reset the flash counter back to 0 & unroot it before I can send it to the Samsung service center.

What kernel version are you guys runing?

I'm thinking Samsung intended to weaken the sensitivity of the back button so that accidental hitting of the back button would not easily register.
IMHO, its a good feature, after 2 months of using my SGS2, I've already accustomed of how to properly trigger the back button. You really need to hit the back button icon, hitting the surrounding glass around the icon won't trigger the back event.

Agree. Even the menu button is like this. You have to hit it dead center. I find the screen to to be very accurate meaning is you don't hit the icons in their proper borders it won't act.

Yep same here. On kh3/revo 2.6/ ninpo2.0.5

I experienced this after I rooted and flashed a kernel (first it was the xwd something kernel). At first, my applications icon at the bottom right had a decreased in sensitivity, but somehow it went away in a couple of days.
Then it was the back button, which was so annoying because that button is used constantly. However, after a couple of days, it too went away. And it hasn't come back for 3 weeks. Currently I am flashed with ninphetamine latest version.

I have the double click issue too. Did you get it resolved by sending the phone in for replacement?

Curious issue with my power button

Hi, I have a curious problem with my power button.
It seems to work ONLY to turn the phone on, once my X10 has booted my power button will do nothing, even held down for a second.
I've tried many ROMs including stock SE and EWJet and am currently on CM7, same problem.
Also, it's managed to function normally again for a very short time (30 seconds or so) after exiting navigation (to a non-dev this seems like evil magic) which I tried repeating but was successful only once or twice.
Using a softkey to power off my screen atm and waking via home button.
I DID throw it recently in a fit of rage and I lost my camera button but this problem doesn't seem to be physical.
Can someone tell me wtf is up with that button?
Sent from my X10 using XDA App

Hmmmmm... If it gets triggered at power on, it means that it's not a hw problem. Try repairing 2.3.3

To me, it does seem to be physical since it happens with all the ROMs you've tried.
Maybe something loosened when you threw it?

Unscrew the phone and screw it up back again. Believe me im not trolling, might just work for you

Help! Cannot unlock screen, touch function not working.

Has anyone of you guys encountered the same issue with your HTC HD2? Care to share the fix you did? Would this mean bye-bye to my HD2 already?

If a clean install (task 29) doesn't help, then I guess you have no other option than sending it for reparation.

It seems like there is a limited life span on the touchscreen. Mine died in October, and I had to buy a replacement because nothing I did fixed the problem.

I had the same issue as you, but in my example touchscreen is slowly dying. For example I can't wake up the phone pressing right (red) button. So I learned that using any other button will not cause freeze of screen. I also discovered that if you gently slap your phone on hand, magically screen starts responding. Weird, but it's ‘working’ like this since 5 months so far.

I just encountered this problem with my HD2 as well. It seems that this is a fairly common issue. Apparently the digitizer for the touchscreen is located directly beneath the red power button and has a tendency to lose its connection.
For me, holding the red power button down with some force for about 5 seconds fixed the issue. Is this temporary? Perhaps, but it has worked just fine for a few days now. Try that out.

Can't Unlock the Phone..
I am having the same problem..I can't unlock the phone..No matter what android Rom I installed.I tried to removed the lock screen and the touch stopped working..But when the phone restarts and you put you pin etc,I can use the phone normally..but when it goes black and trying to turn it on again nothing works on the screen..
Though the hard buttom works..Home screen etc..but can't get the touch to work after the screen goes black!

It's not rom related
I have installed WM6.5 (Stock), Android GB, Android ICS, Android JB But the problem appears to be the same in all
when I press Red button touch doesn't work any more
I would go with digitizer theory
BUT my question is this:
is it gonna get worse? cause for now as long as i avoid Red button everything is OK :good:
and I love my HD2 but if getting worse is possible I have to get rid of it :crying:

Well i had the same problem.now my phone has been to the service centre for reparing

Funny (or sad) thing is we don't have an official service center here
so only option is to replace it or sell it as the way it is

Try this:
Lock the screen normally, screen turns off. (Power button)
To turn it on again by pressing any other screen buttons other than the power button. (DONT USE THE POWER BUTTON TO DO THIS)
I found that if I do it this way, the screen runs normal.

Power button seems to be dying

Hey there
I just started having with my power button. If I click it usually does one of two options . 1 doesn't respond at all. 2 turns on and immediately off.
It just started this week.
Any way to fix this ? Its kinda annoying .
Do you guys have this problem as well?

If your rooted, you can try ''Touch Control''
It's on the playstore. It enables to lock and unlock your device just by sweeping the screen.
You need to be rooted and have a kernel which supports modules (franco kernel for example).
I can provide more help if you want to go through this process.
If you really want to have the power button fixed, replace it. It could be the outer part, or the switch (small circuit board).
Both can be ordered from eBay.

you can also use volume rocker to wake... but you need a custom rom

I have the same problem.. It started becoming worse after the 4.3 update... Guess it's a software bug... I'm expecting a fix.. Let's hope so..
