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.

Broken touch screen?

Hey guys had my phone like a week or so and already it seems its faulty able to see lockscreen try to slide up moves a few cm's a time and never fully unlocks, able to use camera button to access phone but still unable to click anything via touchscreen other then lockscreen.
anyone had this problem or do i neeed to send back?

...when you restart phone it doesnt start with lock screen, can you use it, what hapen then?

still unable to use.

seems a little bit like my problem with TS, go and read my answer in "How is your optimus holding up" thread
my phone came back from service with new software, but i had to send it back again, coz it's probably a hardware failure

...i would send it back.

Hi... Currently i have the same problem with you...
1.Slide unlock it just few cm and cant unlock the phone...
2.On Off Phone... dont let it to stanby mode... few minute ago then can touch like normal...
3.If im go back to standby mode... i turn it on... then will back to cant touch... 4.Until next restart and wait for few minute...just like Num2.
Can i know what problem isit?
Im downgrade and Upgrade the Version... but it still same? anyone know which component is problem?

my phone came back from service about a week ago, everything seems fine so far
it seems, the problem was with the mainboard, it was changed, i'm not sure if they changed TS digitizer or so

GS4 touch keys are dead !!!

Hey guys,
So i bought my phone yestarday,played around with it for a while and suddenly my touch keys stopped working.I keep my touch key light on "Always Off" ..so i thought that maybe if i turn them on,it will do the trick..didn`t work,they don`t even turn on anymore.I did a restart,same thing...only that the phone started laggin` real hard (when i unlocked`it and while using the drop tray).I turned the phone off and on again,same thing..i turned the phone off,pulled the battery out,waited a couple of minutes..same thing.I eventually did a factory reset..didn`t work as well.The phone is stock,haven`t got around to rooting it so it runs on 4.2.2 with XXUAME2 build.One more thing..before i did the factory reset,i digged around the internet for a bit looking for a solution and i came across the *#2663# code...i used that and tried the Touch FW update but it only said "Factory keystring has crashed/stopped working" ..after the factory reset i tried the code again,but the Tough FW button does not appear anymore.Now,do you think it`s a software problem that can be fixed (i would like to avoid rooting since if it does not work i want to send the phone at the samsung cervice center) or it`s a hardware fail and i should just stop looking for solutions and send the phone at the service?Thanx for your time
P.S i had a GS2 so far,rooted`it myself,changed a TON of roms on it and never had a single problem...so for me GS2 > GS4 for the moment

Well, i think that to know if it's a software or a hardware problem you will have to find out by yourself.
First thing to do is to flash a new official rom : http://forum.xda-developers.com/showpost.php?p=41072377&postcount=1 (and you don't have to download the attached files in the post)
Then do a factory reset from the phone recovery (VolUp + Home + Power - navigate with the volume touch and confirm with the power button)
For the roms take a look here :
GT-I9505 : http://forum.xda-developers.com/showpost.php?p=41072426&postcount=3
GT-9500 : http://forum.xda-developers.com/showpost.php?p=41072392&postcount=2
And dont forget to search for the same rom that you have, before you flash , check it by dialing : *#1234#
And if you did all this and it haven't resolved your problem so it's Hardware, just take it to the Service center and don't worry for the warrenty because it will remind active and official even after the flash

Thanks for the info and the advice!
Though now i`m convinced that it`s a software glitch,because i just restarted my phone and the touch keys turned on (unless samsung managed to build a phone that self repairs).I`m gonna be on stand-by with that stock rom,just in case it starts acting up again.
L.E Ok,the touch buttons crashed again,so i flashed the stock firmware and they are working now.Hope they don`t die again
Thanx for the help,again

many lastKi
Well,still no luck ..the touch keys keep getting unresponsive..after a while they sprung back to life and so on
I reflashed the stock firmware a couple of time,same thing...
When i use the *#2663# code and press the Touch key FW update it gives me a "Unfortunately,FactoryKeystring has stopped" error, i should mention that on the menu it says:
- Phones`s Touch key FW version: 0x10
- Part`s Touch key FW version: 0xfa
The only app that i have on the phone is WhatApp ....sooo ..dumb question,could WhatsApp be responsible for this behavior ?
L.E i rooted the phone,intalled CWM and the Google rom for GS4 ..touch keys didn`t even buged so i`m unrooting as we speak,returning all to normal and i`ll send the phone to warranty tomorrow

It's funny you mention that, because my GS4 start to restart and shut down by itself. The first thing I did was remove WhatApp because was always gaving me errors and then pull the battery out for 1 hour, since then no more reboots or shutdowns.

I was on Wanamlite when I experienced that. But all I did was an easy reboot and when it comes back, I wipe caches xD and it comes back..
I also prefer the button lights to be off.. so it's always off from the very start

I like to keep the light off as well,but the light was not the problem,the fact that they did not respond to any touches was ).And yes,if i restarted the phone a couple of time they would come back ...for a period.Anyway,i sent the phone to samsung for warranty,see if they find the problem

Ok,i just got my phone back from warranty (it`s the second time..the first time they just resofted`it ..LOL) ..and it`s all peeachy.They changed the whole screen (i believe it`s called "digitizer" ) and that pesky problem is gone.Also ..before this i had a weird effect when i was scrolling through menu`s...like the screen was leaking or something,but now it`s gone.To anyone else that bumps into this problem (i see that the HTC One has this problem as well) ...well,there`s no way around this unless you replace your digitizer.Cheers

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..

Your device is most likely facing the infamous end button/digitizer dilemma. Since you said it happens after waking up the device from standby (using the power button, right?). As far as I know there is no fix other than a replacement. I don't really remember which part required replacement (digitiser or buttons strip), but I'm sure the only permanent fix was a replacement (until the replacement fails, lol).

If it is just the power button, you could use another button to wake up the phone using button remapper or similar app.
Also, use softkeys for back button, since the digitiser cable runs below these two buttons.

New digitizer is way forward & they like $10USD these days
Like mentioned above you may get some use if avoid pressing buttons but if intend on keeping device for a while repair is worth while.
