I know there are hundreds of threads and articles posted about HD2s freezing with the lock screen but this issue seems different to me. My problem is that whenever I lock the phone the touch screen will freeze entirely. I thought a work around may be to install a different lock screen. After installing that I can get past the lock screen but the touch screen still is not responsive. I have no idea what to do. I already did a hard reset and it still does it. I would like to add that it is completely consistent. It happens every time without fail. In order to even use the phone I have to pull the battery and I get one use out of it before it locks and I have to pull the battery again. Does anyone have any suggestions? I would really appreciate it..
Update: I flashed the original ROM to my phone and the freezing problem still exists.. I have no idea what to do at this point.
Update 2: Narrowed down the problem to being the physical "power/end/lock" button. If I slightly press it but not fully it will go to the honeycomb style menu with all the apps. If I press it fully the screen will go out like normal but then if I restore it, the entire screen is locked up. Nothing will work after that until I pull the battery.
I've directly linked the issue with the power button. I dont know why all of a sudden the power button would have a different function. The work around I found is while the phone is locked and the screen is off I can press the green button to unlock the phone and the touch screen will then function. If I use the power button it will remain frozen. Any ideas what happened?
Hello,
I got some bad news for you, this issue is actually related to the digitizer (hardware) not software. What i would recommend is called HTC for a repair and send it in, it is covered by warranty, hopefully you have warranty.
A lot of people are having this issue, no-one yet has been able to pinpoint the cause, but here is the link a thread with similar problem:

Thanks for the reply. I do not think I have a warranty on this phone considering I bought it privately. Ill talk to Tmo and HTC and see what I can do. Just a theory, I may be wrong. But I live in PA and its been getting below 20 here lately. I noticed today that my work around didnt work when I was outside working on my car. Then I went inside and used a blow dryer to heat up the phone and it started working again. The end button didn't function properly but I could unlock the phone with the green send button. Perhaps the cold weather is shorting out people's digitizers? I don't really know how they work so that's why i said its only a theory. I bought this phone in the spring and didnt have an issue until now when it started getting really cold.
Hi to everyone in this forum. I've recently received as a present a new toshiba folio 100, but, since I'm experiencing an annoying menu button flashing, I've thought of it as a software problem so I upgraded the folio using the foliomod1.3c and applied the rotate patch and also the 1.3c fix patch. The menu still flash with no apparent logic. I've tried to kill all applications running and it's still there. It seem to come up and down at random. I ask to all in this forum: do you believe it's a hardware issue or is a software issue? Because if it's a hardware issue I'm going to try to have a new folio from toshiba. I'm overall very pleased with the work that Dexter made to make the folio an usable machine but this flashing is driving me crazy. I use the folio basically as a portable scientific pdf reader so I need to concentrate on what I read and this flashing is really annoying. I would like very much to thank you all in this forum in advance for all the suggestion/help you could provide.

I have a request that serve All those who suffer MENU crazy button .
Is it possible to prepare application you can setting ON/OFF the MENU button
Most of the time useless button.
sometimes button jump after 10 minutes, sometimes after an hour
Usually I fix the problem by changing the settings with FolioButtons 1.1.
If you could add to FolioButtons on/off operation for menu Buttons was the best.
Hi teknoraver,
Can you add enabled/disabled menu button in foliobuttons application ?

I am pretty desperate about this issue, because none of the methods seem to help...
Right now the buttons work opposite- Menu button flashes mad and none of the other 3 responds...dont know how it happened
Just a thought- while the folio is booting up the menu button ALREADY flashes! I have zero understanding in there but isn't it a process that loads / starts early in the line?
I appreciate everyone's effort trying to solve this bug as it makes this handy tool a useless pile of crap.
I was wondering how many folio users are suffering of this crazy buttons madness.
Mine was crazy from the very beginning; I sent it back for repair and toshiba only did a firmware restore... Nothing changed at all!
It makes my folio almost unusable!
bye bye crazy buttons
After two weeks of testing and a complete breakdown of my folio100, I finally find the problem or just crazy buttons and freezing of the screen.
I drag a thickness in the screen in the bottom right corner of the screen to isolate the audio connector and it works better than a miracle again.
The only downside is that the screen comes out slightly from the slot but nothing really bad.
The thickness I put slightly too big or-1.4 mm I'll Demount next week to put a finer and I'll try to take pictures in passing.
Note however that the loss of waranty is innevitable.
Sorry for my bad english ;-)
I think it's a hardware issue and even a build quality issue.
If i hold my folio at the side of the buttons, i get the flashing buttons problem (even the foliobuttons app will not help), if i hold it at the other side, i've got no problems at all.
Do you have an animated background? Because I saw that some people had this issue with an animated background...
Hi Mshr73, nice first post indeed
Could you post some pictures of what you did?

I really don’t want to be too quick on this, but Dexter’s 1.4 seems to bring relief to this issue - for 2 days I have been running this mod the menu button stopped flashing!!
Any similar impressions on this?

No way pal, I guess I'm in the opposite situation. It still happens to me, and sometimes I think it even got worse... well, I can always look at crazy keys as a "special feature" that no other tablet will have!!!
I just tested without thickness under the screen, with foliomod 1.4 and after a few hours I again the problem of crazy buttons.

Well, I just finished dismantling e reassembling my Folio. Following your hint, I cut a piece of paper and put it between the audio connector and the back of the screen (yes, it was metal vs metal). I'll see whether it's gonna work or not. Crossing fingers for now.
Not that I'm so confident in leaving a piece of paper stuck right where the DC input is .
BTW, did you try with a smaller thickness? Even if this is the problem, I'm wondering whether a piece of paper would be enough or not.
thyself can someone. post pictures of before and after details?
we will be much appreciated
i didn't have the crazy buttons issue this far in 2 weeks, just my home butten needs to be pressed harder. I'm pretty sure it's hardware related, i read often that users experience it when changing from an warm room to a colder one, or in regions where its verry humid(some circuit closes maybe...). so Mshr73 is on the right way as far as i can tell.

Anyhow, it is so disturbing, that I was already considering to send the tablet back to Toshiba...

I'm looking forward to your pictures, too... because my trial simply didn't work.
I tried with both a single piece of paper and then with 2 pieces wrapped in tape. I put these spacers between the back of the display and DC/audio connector.
In both cases, the crazy keys phenomenon started to happen after 15-20 minutes of usage.
In most cases, it starts to show when I unlock the device. As soon as I unlock it, home and menu buttons light up with no apparent reason and go crazy for 10-30 seconds.
Then, I even tried to loosen just a little the screws (I read, somewhere in the forum, of a guy who said that he solved his crazy keys and screen lag problems this way). I mean, all screws are now locked but not too tight. Well, I have to say that I don't have any screen lag anymore (I even removed the piece of paper, from the battery area, which used to solve the issue before) but crazy keys still happen. I'm going slightly mad

Well ... with a piece of paper the problem Come back.
I handed a piece of cardboard and the problem disappears.
I think that to raise the screen to solve them but I'm still not 100% sure.
My Atrix's screen has become unresponsive in a vertical column (if the phone is in portrait mode) that lines up about with the W, E, and S keys. Restarting fixed the problem for maybe 20 seconds or so after the phone became usable, but doesn't seem to have made a difference after about the third time or so. I also removed the battery and held down the power button for ~45 seconds and then put everything back together, which also seemed to have helped for a minute or less before the stripe became unresponsive again. I also restored to yesterday's backup a couple different times (CM 7.2 stable), which also temporarily helped.
So after a brief search, it seems that the digitizer may be the issue. Is there any way to tell for sure? At first it seemed like a software problem, but it could also just be the digitizer acting erratically because it's going out, so I'm not really sure, and I'd rather not attempt a repair that may not be necessary.

there are some screen tester apps on Play which you could use to see if, in fact, your digitizer is a problem.

Do you have any specific recommendations? I downloaded the touch test app from here (http://www.freewarelovers.com/android/app/touch-test) to see how much of the screen was misbehaving and discovered that it was a perfect stripe the whole way down, but because I'm not terribly knowledgeable about troubleshooting phone hardware, I don't know if that's telling me it's the digitizer or something else. I attached a screenshot that shows where the stripe is.

From what I've seen on here it does look like your digitizer is at fault. I have never had to change mine but there are plenty of posters on here who have and you can look at their experiences to assist you. Also, here's a video I found so you can see what you'll have to do. Good Luck!

That's unfortunate, but at least I know that's what's wrong. Thanks for your help!
Everytime I go to use the on/of button for anything, I barely press it and sometimes it doesn't work, other times I quickly press it and it thinks I held it for the menu to come up to reboot or power down. But most of the time... It just reboots on its own if I use the switch. Any way to by pass it? The switch itself I think is just super sensitive, I barely have to even touch it. I've taken phone apart and cleaned around the switch. I'm trying to hold out till the Galaxy S 4 comes out... Hopefully soon!!

Although I can't offer a fix... The galaxy s4 goes for preorder for at&t on the 16th of this month for $250 I believe. And T-Mobile is releasing it for $99 on may 1. I think that is all that is currently known about any galaxy s4 release dates. Hope I kinda helped in any roundabout way.
Galaxy S3 T999 rooted and flashed more than daily.
Brand new off contract nexus 4. 250 dollars. If you can deal with the limited internal sd card space and don't have to have your entire music collection with you at all times like some people here lol.
Free Apps to Help
I have the same issue, can't touch the power button. I smack the button a few times to get it to behave. I have installed the following two free apps so I do not have to touch the power button again.
Auto Screen On.
Button Savior(Root)
I am not allowed to post links to the apps, but they can both be found on Google Play.
You have to have root and you have to read the instructions for each app.:good:
Thanks to everyone, I am rooted and running CM9, so that shouldn't be an issue and I'll check into those apps. Just need to make til I can upgrade to the GS4. Thanks for the dates cuz now I have an idea of how long and I'll go order it that day. If that's the preorder, then when is the release date I wonder?

I think it's absolutely fascinating how we both seemed to develop the problem at the same time. Could be that many others will soon suffer the same problem. Although I'm definitely going to look into those apps now, I found a temporary fix myself (and it could just be coincidental anyway). I pulled the battery out, pressed my power button repeatedly about 100 times, and now I'm able to use the power button again without it sticking and causing this problem.
The weird part is, that physically, the external button wasn't stuck at all. I could still click the button as many times as I wanted even while "stuck" symptoms appeared on my phone, like the power menu coming up, or a reboot. My guess is that the hardware problem lies somewhere between the physical button and the electronic circuitry within, but I haven't actually stripped down the phone and looked inside. But perhaps jamming the button a hundred times helped decrease the chance of the internal "signal relayer" getting stuck.
I had a similar issue with some keys on my laptop after a little kid played with it and got my keys messed up. Outside button was ok, something beyond that was not (so pressing "s" once would lead to 40 s's appearing on my document). Repeatedly pressing ended up helping out quite a lot.
Nonetheless, this may end up being a very useful thread for others later on.
My GF i777 was having the same issue reported here. I just sent it into mobiletechvideos.com and had the power button on the mother board replaced for 40-50 bucks and it works perfectly now. I would suggest using them if you want to keep your i777 working

I am having this same problem. I started a different thread a few days ago about power button issues that at the time I attributed to the recent software update. But it was apparently just very coincidental, and after some tinkering I was able to get the button working using similar methods described in this thread already. After I got it working again, I rooted and successfully installed AOKP 4.2.2, but now when I manage to get the power button to send a signal it pulls up the shut down options screen and then restarts about ten seconds after that. I assume it is still the same hardware issue, but since the restarts only began occurring after flashing the custom rom I can't entirely rule out the possibility that it is some how related.

If you flash back to stock and you still have the button problem, then it is almost certainly hardware. Did you do that yet?
I actually just flashed AOKP a few days ago. Instead of using one of the applications above, which either drained my battery (auto screen on) or wasn't entirely convenient (button savior), I've got a different set up.
In rom control, activate "volume rocker to wake." It's not a hundred percent, oddly, but it gets the job done. This will help with screen on.
For screen off and power menu, I added a navbar with the second smallest height (30 dpi?), with the power button on it. Now I permanently have a the ability to turn off my screen, from whatever I'm doing, with just one click. Long pressing it gets you the power menu.
As a side note, I added screenshot to the power menu so I wouldn't have to hold my power button for that either. But no, I haven't tried using the nav bar power button with volume down for screenshot, because I'm an idiot and just thought of that now.

I haven't had the opportunity to do that yet. The restart issues may have begun when I flashed the Siyah 4.3.3 kernel before installing the rom, but I probably won't have the chance to tinker with it until the weekend.
Edit: I have also noticed that I can only reliably use the volume buttons to wake my phone up from sleep when it is plugged in.
Weird, I just started getting this problem today, too. Kinda weird how this all happened to us in the same month
Add me to the list of those whose power button suddenly and mysteriously died. Opened up an email Sunday 4/14, the phone rebooted on its own, and when it restarted the power button no longer worked. My suspicious is it's somehow software/rom related. I'm running Task's AOKP 4.2.2 (4.1.13), for what its worth. If everyone with the issue posts their experience maybe we can figure out what's going on...
Mine started doing the same back in March. Pressing the power button would cause it to reboot and sometimes bring up the power menu, as if I was long pressing it. Then the power button didn't want to work at all, sometimes. I tried everything I could think of, even reverting back to stock, but the problem persisted. Then I finally found that pulling the battery and pressing the power button a few times fixed the problem, for a while anyways. If I don't do it every 2-3 days, it starts happening again. I've actually seen something similar happen with notebooks before. A charge manages to build in the motherboard and the system won't power on. Removing the power supply, pulling the battery, and holding the power button for 30 seconds to allow the charge to dissipate actually fixed the notebooks. That's where I got the idea to do it with my phone. Just wish I didn't have to do it every couple days.
My power button stopped working a couple of days ago and I tried this solution http://forum.xda-developers.com/showthread.php?t=1193057&page=2 post #17. Just take the phone apart, spray the power button with the electrical cleaner, and continuously pushing the button for a while (2 or 3 min). Keep the button wet while pushing it. Let it dry, put the phone back together, and start it back up. You should be able to tell whether it worked because when you put the battery back in it will not immediately start back up.
Hello all and please forgive my poor english
I really love this tablet (thickness, battery, weight, screen) BUT i have a major problem with it : i often need to tap 2 or 3 times on something in order to launch/select it and it ruins my global experience with the tablet :crying:
Do you guys have this problem and is there a way to alter the sensivity of the screen ?
Thanks

Yeah that's what i expected but wanted just to know if others had the same problem and if there was already a workaround for this
Many people have this problem, including a number of reviewers.
Nevertheless Sony refuses to acknowledge the existence of the issue. When I called them, the guy said "You are the first to report such a problem". (Probably he lied and was advised "from above" to say so...)
The customer is left in the cold!
Some people have a return policy - what if one waits for a software update, the return period expires, the update comes, but it doesn't fix the problem and it turns out to be a hardware problem??
The information politics of Sony and other companies (yes, Google, you too!) is an absolute PILE OF S**T!!
Yup, me too. The annoying thing it is difficult to document. Yesterday my tablet was charging and I turned the screen on using power button - lock screen didn't react at all to my inputs. Tried switching screen on/off a few times but it didn't help. Also tried double-tap to wake with no success. Went to get my camera to document, then of course it started working...
I've written this elsewhere, but this is how I notice the touch screen problems:
For me the tablet randomly doesn't recognize touches during the below instances. In all cases either going to the home screen and relaunching the app or turning the screen off/on will solve the problem. The problems occur several times per day but not constantly.
Sometimes opening apps will cause everything but the bottom android-buttons to be non-responsive. This can happen in any app it seems, including native ones such as Google Play.
Sometimes the lockscreen doesn't recognize touches at all.
While charging I've had issues getting the touchscreen to recognize touches, disconnecting the charger has helped.
Double-tap to wake seems to be very moody, sometimes working sometimes not. Sometimes it turns the screen on even by me just holding the tablet with my palm resting against the screen.
While not a bug per se, also the android-buttons seem very picky that you have to hit them right on the spot to work.

One forumer said he thinks that switching OFF Stamina mode helped a little bit...
I don't have my tablet with me, can someone test this ?
"A little bit" help is NOT enough.
The touchscreen MUST work perfectly, whether with Stamina Mode on or off or whether with Mode XY on or off. No discussion.
Sony HAS to fix this.
Already solved in .55 firmware

The same experience with Z1 compact and support. Told them the camera is really broken - they told me there is absolutely nothing wrong with the camera and I'm the first one who got this problem. That was some weeks before, now they officialy added that maybe some devices are defect.
But that´s Sony, they give a **** about u, don't even try to contact the support.
I'm also having this issue, if I'm using the Sony sleve it's impossible to use the touchscreen as it will tip over when I press hard enoug for the screen to actually register it.
No problem here.
Only early days yet. The only prob I've got atm is Dropbox isn't showing up in the Album.
Edit: Fixed the Dropbox problem by using the Dropsync app.
I also seem to get this. The tablet works fine when tilted at an angle but for some reason can be completely unresponsive when it's laid flat. Would this suggest a hardware issue or a software bug?
I also get this, sometimes it's like I just need to press harder (so hard the tablet falls over when using the cover as a stand), but other times it seems that no matter how hard I press or how many fingers I apply it doesn't register a thing for periods at a time.
I'm lead to believe that this is either software or firmware considering the intermittent nature. Are there any custom ROMs out yet that we could flash to eliminate the software aspect?
I have same problem, most noticeable in Chrome, switching tabs fails to register 10% of time. I can only think Sony have a hardware quality control issue with the digitizer as if it was firmware related, surely everyone would be suffering. Strange none of the reviews have picked this up, but I'm going to have to return mine.
No, no, no.
It's most surely a firmware problem!
The electric current threshold for registering a touch is set too high. So if the tablet lies on a non-conducting surface, and especially if it was not touched for a longer time, there will be touch problems. Also touching the tablet with a fingernail will not suffice because nails conduct current worse than skin. Other tablets which have a lower current threshold also accept fingernail touches.
I'm very sure: If you hold the tablet with one hand and touch with the other (and don't accidentally use fingernails), touch will be OK! Right? This is because more current will flow.
The .55 firmware which is out for LTE devices already and will follow for WiFi devices lowers the threshold and thus fixes the problem.
Up to then always take the tablet in your hands when operating it.
Interesting theory, just gave it a go, inclusive, but does seem worse in case. However if Sony aware, why have they not rushed out firmware as otherwise initial user experience is ruined.
QUOTE=hasenbein1966;52005720]No, no, no.
It's most surely a firmware problem!
The electric current threshold for registering a touch is set too high. So if the tablet lies on a non-conducting surface, and especially if it was not touched for a longer time, there will be touch problems. Also touching the tablet with a fingernail will not suffice because nails conduct current worse than skin. Other tablets which have a lower current threshold also accept fingernail touches.

POTENTIAL FIX FOUND (ROOTED ONLY)!
Rooted users can try this fix, works for me! Touch seems to work perfectly now, also when tablet not in hands and lying on non-conducting surface!
Edit the file
/system/usr/idc/clearpad.idc
and alter these two lines:
Code:
touch.pressure.scale = 0.0001
(original value: 0.1)
and
Code:
touch.filter.level = 1
(original value: 2)
Don't forget a nandroid before
Please report whether it helped! :good:
P.S.: just for the curious - on the first Tablet Z, the two values are also lower: touch.pressure.scale is 0.0074, and touch.filter.level is also only 1.
Thanks for suggestion but dont wish to root (I use it to watch Sky which wont work if rooted) - seems there is more assistance on this forum to the issue than from Sony. I'll give it another week for a firmware fix before returning it.
elaborate...

If this is fixed in the 55 firmware then how do you get it?
I haven't had a firmware update?
I'm using 16GB Wi-Fi only in the UK

My bad, didn't read all the way through, ignore me.
Now after a few days I can say:
With the root fix described above, my tablet works like butter. Simply perfect. :good:
Only instance where I have still problems is when the tablet was lying around for a while and I try to operate the touchscreen without taking it in my hands. Then sometimes (not always) the screen doesn't react, but only for a short time.
The problem seems to be related to static electricity.
