I've been experiencing an issue with the Home button since the day I got the device.
A few times the Recent Applications screen has popped up seemingly on its own, while I was in the middle of doing something else. At first I thought it was just a software glitch and carried on. The haptic feedback pulses twice quickly. The backlight of the Home button turns off, the backlights for the Back, Menu and Search buttons stay on, the Back, Menu, Search and Home buttons no longer respond to touch or generate haptic feedback, essentially paralyzed. It remains this way for approximately nine seconds before the Home button lights up again and the all of the shortcut buttons become responsive again, otherwise the only way to get out of the Recent Applications screen is to either cycle the power button and unlock the screen, or select one of the recent applications.
I have figured out how to reproduce this problem by pressing around with the very tip of my thumb along the seam where the glass and plastic lip meet with a little more pressure than normally necessary to register a touch. I am careful to avoid touching the normal hot zone for any button. I start from the far left corner under the search button, and make my way towards the home button little by little. Somewhere between the Menu and Search buttons when I release my thumb after pressing firmly, the haptic feedback pulses twice and the issue occurs. I can reproduce this issue anywhere along the edge on the bottom right half of the phone and about 1" up the right side of the phone, far from the Home button.
I suspect there is something wrong with the capacitive layer of my screen.
Please see if you can reproduce this or something similar on your phone, just bear in mind that you will need to press firmly (not too hard but not soft).
The unfortunate thing about this problem is that it can be activated inadvertently while gripping the phone during normal operation, interrupting whatever you are doing for the time it takes to resolve itself.
This is literally the only issue I've had with the phone in the week I've owned it and I am considering whether or not I want to play russian roulette with exchange units (and other issues like bad screens and bad weak back buttons) because everything else seems to be perfect.
Video of the issue in action here:

Same thing happens with me on the swap unit I got today. Bummed like no other.
Tried replicating this with my device with (thankfully) no results.
one and one... I wonder how many other phones are affected then, and how many people have it but haven't noticed yet, e.g.; "you're holding it wrong".
Hm. Just tried to replicate this on my Nexus S, no issues.
Mine did the same thing at least twice a day. However, it has not happened again since the GRH78 update. (Knock on wood).
Have your received the update?
This just happened to me for the first time about an hour ago. I have the new update too, sadly.
Yes I have the update.
I can't replicate this problem, but nonetheless, it still happens.
I have this same problem with my back button. I can't replicate it but it just randomly happens to me. I have the update and I also tried using Paul's Tom and it still happens.

This happens with my back button.

happens to mine too, also the home button. doesn't bother me too much, though. and I also have the update.
I had something even weirder tonight.
I did a factory reset, then proceeded to install everything back on when I noticed that my home key wasn't doing its job at all. Still had the haptic feedback so the input was received, but it did absolutely nothing. So I did another factory reset and that seemed to have cured the problem. My home button is working again (but i still have the other problem from time to time)
Had it happen again inadvertently today, if you notice from my video the spot where it can be activated next to the Maps icon also happens to be conveniently where your finger ends up when swiping to unlock. I was holding the phone one handed and unlocking with my thumb and it triggered the problem. Might try for an exchange this week. It shouldn't behave this way.
For those of you who are experiencing it with your Back button, does the backlight turn off for 9 seconds on your Back button?
I don't know everything about how the hardware works but I'm guessing that there is some kind of short, the controller for the capacitive layer gets confused and resets. Could explain why it takes the same amount of time to come back to normal every time. It also seems like it might be related to case/screen flex, where pressing on a part of the case bends the capacitive layer just enough to short the circuit.
This issue came on my two days old Nexus S too, but with the back button. It has happened two times now. I think that's a software issue that come along with Gingerbread. It's something like it registering a touch and sometimes the OS think it was the buttons that were pressed...

Does your back button black out for ~9 seconds?
I haven't had any button issues whatsoever since I got mine on the 24th.
No, more like two seconds.

Here's a new video shot today showing the issue occurring with only normal light touching:

Also last night it happened while I was inserting a cable into the headphone jack.
OK now I know there isn't a Ghost in my phone but at times my phone behaves like its possessed. The problem is with the touch screen. At times my phones starts to do stuff on its own. Like open random apps, bring down the notification bar and then brings it back up. Once it even opened my whatsapp and then opened the keyboard and typed a message and sent it to an contact. And during this time it doesn't really respond to my touches. But it happens very rarely like ones in two days and that too for a min or two. Been happening for a two weeks now. I have the latest CM 7 Nightly installed. So what do u reckon is happening? Is it a software bug or an Hardware bug? And how do I fix it?

I had the same problem. LG Service Center said, that they need to change the touchscreen. Try to flash another ROM, if you get the same problem, then unroot and flash stock firmware and go to LG Service Center or change the screen yourself
But I hope it's your ROM, good luck!
on my sgs i have this weird ghost while charging.. are you running ics?

Change your kernel, these may be kernel panicks.

This could be a reason cause it all began when I flashed DJNoXD's Kernel 2.5.2. But then I re flashed the latest CM 7 nightly over it and it continued to show the symptom's. Also I did not over clock, never did.
Today when it showed the same possessed behavior, I pressed the power button and it at once came back to my control. So I guess its a temporary solution to it.

It never happened during charging.
Found the Culprit
It was being caused by a pair of external speakers, which has it own power source, which I connected to the phone. I am guessing the speaker was sending some kind of charge to the phone. When I connected the speaker, the touchscreen completely stopped working. and even after I disconnected the speaker the touchscreen would continue to behave the way I described in my first post. Probably stored that charge somewhere. Bottom line, now that I have stopped connecting the speakers its stopped that behavior. There case solved. Feel like Scooby Doo. There was no Ghost after all.
Lolzz..
The random bottom part of the phones touch screen starts to be randomly pressed,
It’s like the phone has a mind of its own, sometime is a few phantom presses and others it’s a full battle to keep the phone from random opening apps and calling people till I hit the lock button or pull the battery.
I have seen a few post about the phone over heating causing this, at 1st it seemed to be my issue, but now the phone does this while feeling relatively cool and right after removing the battery for a bit.
after some time the issue almost stops, this time i have a bit of a dead zone near the bottom right.
can this be calibrated or do i need to replace the part?

I think your display digitizer is acting up. Try a different ROM and if the problem persists I think you should get it replaced

Hello, you solved the problem of their touch screen? My work normal, but suddenly begins to do the same as yours.
Newbie Searching for help!
I literally just joined, and this is my first time doing something like this. So, I don't know how to request help for specific issues concerning my LG Zone 3. Can you give me some direction? I chose you because you are a senior member and i have similar complications with my keyboard.
Thank you and I hope to hear from you soon.

Just bought Z5 dual in green.
Still brand new, 1 hour old.
A moment ago, power button got a bit sticky and would not pop back up.
Therefore could not turn screen on.
It has gone away since, only happened once.
But I am fairly sure that after this episode, power button started to make a tacky clicking sound every time I press the button.
QUESTION
does your z5 make this sound, and it's just that I failed to notice it from the beginning? Is this normal?
Was the power button getting stuck once a fluke, and won't happen again? Or could it be manufacturing defect?
Bit of a hassle to go back to the shop for exchange, and wanted to know if this sound is normal amongst other users or not.
Thanks for your replies in advance!
Any comment or opinion is greatly appreciated!
My power button clicks every time I use it which isn't often since I have tap to wake and the fingerprint sensor set up. Never got stuck though.

Just wanted to check, that my button clicks in sensation when pressed, as well as making the clicking sound at the same time.
Hard to describe, but I would say it sounds similar to a pc mouse clicking sound.
If I was blindfolded and someone wss clicking my power button, I could have thought that someone was using a pc mouse
Yours sounds like this too?
Yeah, it clicks at a slightly higher pitch to the volume key click.

Yes, mine sounds exactly like that.
Got the same issue, it's like the power button is sliding down, and you have to push it up to make it clickable again.
Thanks for your input guys.
I went back to sony centre where I got it from, and checked other Z5's
Since they all made similar clicking sounds, I decided to wait and see how it goes.
If I get the sticky power button again, I will return it.
Other than that, it is running beautifully!
It runs cooler than my Z3 too!
I got this thing too and i dont know if take it back to support... I started to noticed it up when i disabled fingertip sensor to unlock it just to check some stuff.
So maybe its my paranoia lol

Are you talking about the power button not coming back up? Our the stake clicking sound?
Update in my situation
Since the initial problem, it had not happened or repeated again, so I can say that it has worn in nicely.

In the clicking sound
The Power button is clicky. It is not a fault!
The clicking sound is normal but even mine got stuck once, had to press it a few times to get it to come back up. Yours certainly wasn't an isolated incident.
I have been in a shop checking a new one and the button doesnt need to press so much like mine one. The girl has said me that if i send it to support they wont do anything to the phone because it does work well. Its just a little diference touch...
I will send it to support in december that i wil get a phone from a friend so i can use it while the checking thing
I have a gold Z5 (I know!)
They power button slipped downwards under the casing as I used it. EE were actually really helpful for once and replaced it as I'd only had it 4 weeks. Unfortunately the replacement phone has the same issue. It doesn't affect the function of the button at all, I just worry that it will slide down too far into the body and not come up again.
I don't think EE will replace it again as the guy was very nice and tried a few different ways to log the problem until it was accepted for replacement. It seems to be a problem for a few people, but as long as it keeps working I'm not too fussed! Just thought I'd mention it so anyone else with the same issue doesn't feel alone ?
I am having the same problem, Z5 gold rev2, got the phone on 5th february, wich is now 11 days old, power button gets stuck sometimes, thanks God I have double tap to wake, wich makes things less painful, but I am afraid that this could get worse by the time. Otherwise this phone is such a beatuy! works very well, but this with power button ruins good experience that I have with this device.

I am the OP.
My phone has not become worse. Everything the same, and is working all ok.
From my experience, pushing down on the button AND sliding the power button down towards the bottom of the phone at the same time makes it get stuck in that position. So as long as you avoid the sliding down bit, I never encountered a repeat of the problem.
If it does happen, and I have yet to hear of a power button on z5 that got permanently stuck, all you do is slide it up while depressing the power button.
Everything is still water resisting and perfect.
To add, I've been using it naked, and it is surprisingly scratch-free!
Lately my Mi4 is acting strange. i.e, system getting hanged. Mainly when I switch from one app to another. But it has happened 2-4 times while playing Clash Of Clans. I did wait for 2-3 mins to see it would get back on track.. But it didn't. So everytime when I encounter this situation, I have to use reboot/hold button. The rest of the buttons are cold. Is there anything I'm missing here? If you have any solutions, do share with me. Thanks.

Firstly which version are you on . you can try updating the phone to latest version as miui 7.1 is released. hope that helps.
