Accidental knocking of the power button - Xperia Z2 Tablet Q&A, Help & Troubleshooting

I'm sure this must be an issue for others, but I can't find any discussion of it.
I find that while I'm using my tablet in my hands, I keep bumping the power button and locking the screen.
Is there a an app anyone knows of to resolve this? Or a Workaround? I figure if there was a two step lock process similar to the old unlock on Nokia phones years ago, or something else clever to make it much more difficult to bump...
And I'm very keen to avoid rooting.
Ideas?

The workaround is:
Don't hold the tablet so clumsily.
Yes, you are the only one with this problem.

Man... if that's going to be your reply - just don't reply.

It's simply the truth, sorry.
I even can't imagine how I could manage to hold the tablet in a way that I always accidentally press the power button!
Whaddaya doin', man??

I do it from time to time. Usually it's when I try to reach my thumb to something that is close to the middle of the screen. The part of the palm of my hand just below my index finger would sometimes accidentally apply just enough pressure around the power button to pass the button's pressure point (when I'm holding the tablet with two hands in landscape mode and don't want to switch to one-hand grip just to tap something near the middle)

[Q] Power Button: Is yours stiff and unresponsive?

I got to thinking about how bad the power button is on my unit, compared to the OG Transformer:
How is everyone's power button? Mine is stiff as a day old dead dog, and I find myself squashing, pushing, pushing again to get the unit out of sleep mode. My OG Transformers (all 3 of them, have a nice springy detent of perhaps 1/32" - 1/64" (damn America for never adapting the Metric System! I don't know my millimeters from my water meter) The new button is just a mush,, with no noticeable travel)
connect your device to the computer (in debugging)
and run 'adb logcat'
watch the window every time you press power. there will be a noticeable like like screen state, or power state, i cant remember exactly.
"Is yours stiff and unresponsive?" must resist.... urge to..... Okay, I'm good now.
My power button seems fine however I've got to press it at just the correct angle to get it to work. Put the pad of your pointer finger on it then give just a slight 'curl' towards you and she should light right up.

Thank you for the "Button Pressing Method" lesson. The funny thing is, your technique actually helps! My "stiffy" is a lot easier to manipulate than before. You must have a LOT of practice with these things!
It's actually how I use the power button, so it was pretty convenient to change it around into something perverted.

I've found that... sort of "pinching" the power button (thumb on front of tablet) makes it work very well.

Capacitive buttons response

Right, the reason I have started this thread is, I see some discomfort using Back capacitive button. I am not complaining that buttons don't respond to touch, they do. All 3 of them.
Let me give you an example: I am playing with the phone, doing something on the screen. After, let's say few minutes, I want to go back, so I touch Back button, but it does not respond. I press few more times and eventually it registers. Some people would say "hit and miss" or "there is an issue with capacitive buttons". I say no, because I am touching it there, where I supposed to, also once it start registering, every time I press it, it registers (I have haptic feedback on, so I know it works). I have problems only, when I am not touching capacitive buttons for some time.
I hope I explained this well. I think this is, what in some reviews has been described as "hit and miss" or "capacitive buttons not register". Do you have the same problem? If yes, why is that happening? Is it software or hardware?
I don't have this problem because I realised that the most sensitive and best working area
for left/right button isactually in the inside space rather than exactly on those little points.
So once I press slightly to the middle, it works. It requires also a little longer press.
Ok, I will try that.
I do agree on the buttons. Probably the only thing to get used to, but one you do, no phone like it period! This is sick an amazing phone it is rediculous
The back button on my phone @ left corner is actually the best out of the three. and maybe I feel the same way about the middle "HOME" button where it registers little higher than the other two. actually I have hit it few times accidentally while I was trying to push the space bar on keyboard.
But every time I felt the haptic feedback, button worked.
I am happy with the performance of the buttons. It seems like they work like the power and eject buttons on the PS3. They respond when you remove your finger.

The only thing I have to get used to...
Almost no extra hits anymore...
One touch is most of the times correct registered :-(

Right, so by looks of it, there is no issue. Something I have to get used to. Thanks a lot guys. I also hope it will help future buyers as well.
I have not had any problems with the capacitive buttons so far and tbh i prefer them to hardware buttons like on the arc/play etc
No problems here. They are better than the one's on a Samsung galaxy s2.
I used to have a Nexus One and the buttons are similar to that, you sort of have to roll/slide your finger upwards on the button ever so slightly.
I barely notice it but I know what you mean.
I find that if you aim just slightly to the middle of the screen rather than on the dots then it works great

How can you be serious? I have both, and as perfect as the Xperia S is as an upgrade, its capacitive buttons are not as sharp and fool proof..that's my only gripe ...
Example situation of problem:
Right after finishing recording a decent length FullHD video, pressing home or back needs to be done repeatedly to register (MOST of the time).
Not a deal breaker, but I so hope this is software related..
I have the same issue but after one day of owning this phone im learning where to press to get a response first time
Posted with my Sony Xperia S
Well I started off doing the "pressing above the dots" thing, until I noticed you could also swipe them (I swipe from the transparent bar up)....now I'm used to swiping them and never have any problem
I'm liking the swiping method, its impossible to miss and well..it's kinda fun for some reason

I am just glad we have sorted it out and it turned out it is not a software or hardware issue. After reading some advises, my phone cooperates with me much better.

[Q] Disable Home Button Unlock?

OK, so I've had this phone for just a few days now, love it aside from the physical home button. Not a fan of it at all, but now I've found myself going to the unlock screen when I put the phone in my pocket. Can the home button to unlock screen be tuned off? I just want the "power button" to unlock the screen.
Please help as this is driving my wife and I nuts with these!!!
Thanks in advance!
Hey,
Sorry, but it's a mystery, how you can power on your screen with home button.
You should also have trouble with the power button also, as it's on the side.
Either you wear very tight pants, or your pockets are very narrow ;-)
Side button is not a problem as I have had a Captivate and Skyrocket before, but my big mitts get in the way! ... and I have having problems with putting it in cargo short pockets, lol.
Nobody made an app or anything to take this button out of commision while screen is turned off?

I've seen this exact issue with both my old SGS2 and my new SG Note 2.
For me at least, it looks like this only happens with 3rd party lock screen apps. Most have a built-in workaround that basically just sets that locker to the default launcher so that when you press the Home key at any point, it locks the screen. This keeps it from unlocking, but also makes the home key virtually pointless and disallows you from using any 3rd party launcher.
So right now I'm stuck having to use the stock locker app, since I'd much rather use my Nova Launcher and not risk butt-dialing people all the time...
Anyone heard any solutions for this issue yet?

screen calibration

Is there a way to "re-calibrate" the screen or change the sensitivity?
I have found that when I need to press a button near the corner of the screen, (like on a friendstream widget to refresh), I usually have to press it several times or use my pinky.
I'm thinking either the "alignment" is off or the sensitivity needs to be tweaked (maybe my fingers are too big)
When I first started typing on the Inc 4G, I noticed that sometimes it seemed like it was missing letters I was typing. As I started using it more, I realized that my hand was barely touching the corner of the screen next to the recent apps button, since I was used to using a small phone, the original Incredible. However, once I realized I was doing that, I stopped doing it. I have to consciously make the decision to stop every time I notice myself doing it. I've only been using it for a couple days, but I'm doing it less now, so hopefully I'll stop completely soon. I don't understand why it thinks the corner of the screen should be touch sensitive, because it's almost a full centimeter away from the recent apps button.

interesting, I'll have to keep an eye on that.
but I'm trying to hit a small button on the top right corner of the screen.
I have the issue I mentioned before when I'm holding the phone in landscape mode with the capacitive buttons on the right, the base of my index finger where it meets my hand barely touches the screen about a centimeter above the recent apps button. I don't use the FriendStream widget, as I don't use social networks at all, but if the button is too small, it may be that your fingers are too big, but more likely you are touching the screen somewhere else. I only figured it out when I took my right hand away from the screen and was still typing with my left and the keys were working much easier for me.
Try taking the hand you're not using to press the button and put it on the bottom of the phone to hold it steady, then, using your other hand, only touch the screen where the refresh button is with your largest finger and see if it works. It may seem like really basic troubleshooting, but sometimes that's the way to go.
Failing that, try to go to Settings -> Language & keyboard -> HTC Sense Input -> Advanced settings -> Calibration tool
It only lets you type in portrait mode, which is kinda dumb since most typing is done in landscape mode, at least for me. It would be nice to at least have an option to do it in landscape.
Anyway, I hope one of these solutions helps.

The app you linked is difficult to use. I have to press it so hard that my screen does the LCD ripple thing mentioned in the other thread.

no this isn't true.
you don't have to press hard, you have to press in the correct spot...
this phone's display is tough to get used to.
prime example, trying to exit out of a single app in the stock task manager, is very tough, and always opens the app instead of hitting the x, it's annoying, but it's worth it, IMO
but here is a vid showing that I have zero difficulties going through the set-up.
that and a little teaser of the ROM Nitsuj17 and I are working on

Well, I was having difficulties using it. I don't have fat sausage fingers, and I even tried using my pinky finger and pressing directly on it and everything after the first dot just didn't work unless I pressed very hard on it. Now that I've used it once and calibrated it, it works much easier doing it again. Perhaps it was just that the factory default calibration for my phone is just that off.

Power Button Problem

Hi,
My power button was not working properly (at all sometimes) so I decided to open my DNA and Fix it...
I opened it a and found that the actuator was broken.
Now my power button looks like the picture I attached... do you know the way I can short the pins to power on the phone? Also do you know how can I fix it?
Best Regards.
UPDATE 1:
I found the problem of my power button sometimes working and sometimes not...
Just like Nexus One power button, the inner cable was not flexible enough, so after a while it just get cutted. So, the only chance to fix it is to replace the whole main flex cable... not cheap and hard to get.
So I looked for where that flex cable goes in to the mainboard... and I found it.
It's the PIN number 13 on the connector on the right side of the motherboard. That's the pin that controls the Power/Lock button.
When that pin is "grounded" the circuit is closes and it activates the power button.
I recommedn to solder on the flex cable and not the mainboard as it is very difficult.
If you have any question just ask. I really don't have the time to make a complete guide, but I can surely make the time if you are interested.
Come on.. Any help would be appreciated...

I actually broke that off while trying to replace my screen. I've resorted to using sweep to wake kernels and if my phone turns off, I have to boot it thorugh ADB. If anyone can help on this it would be extremely helpful for me too.
Too bad mu friend. Could you plz upload a picture of your broken power button?

Sorry about not replying. I would prefer not to have to take my phone apart again for a pic. Its exactly what yours looks like. I managed to lose the tiny part that fell off of it though. If you've found anything I would still love to hear about it.

Looks lik you must replace the entire flex.
That would be the easy fix... but they are out of stock anyway...
I made some discoveries that might help. I updated my first post.
Interesting. Great findings so far.
I have a very oddly behaving power button. After short periods of sleep/screen off the power button works reliably. After long periods of sleep/screen off it takes a firm long press of the power button or perhaps two presses of it for it to function as intended. I suspect it will soon stop working entirely. Any additional advice to salvage the device afterwards or fix it preemptively would be greatly appreciated.

I have a Droid DNA that's having power button issues, at this point the only way I could get it to turn on was to plug/unplug from charging cord.
I was going to get it fixed and found that I would have to buy the part and then take it to Cellairis who would then fix it for $40. (not a bad deal)
When searching for the power button, I found out that there's a Gravity Screen App that will power your phone off and on! (of course there is, and more than one)
So for now, problem solved!
help asap!!!
what did you use to ground the pin?? i tried a random wire and i couldnt get it to turn on
