On-screen buttons getting pressed during calls

Narada — Mon, 19 May 2014 20:38:47 GMT

Hi all,

First post here. I just bought my z2 and I absolutely love it but am deeply disheartened and concerned by one problem I'm having which pretty much is the most important thing I need.

Almost every time I make a call - the mute, speaker, end call or other buttons get pressed while I'm talking. I've tried to make sure that the proximity sensor is covered by my ear and it still happens. I've also run the diagnostics and although they pass I've noticed that the vibration for the proximity sensor test does not always stay on if I put the phone up against my ear and move it around. Eventually the vibration turns off and some on screen buttons are pressed.

Is this a problem with only my Z2 or a design fault. I'm gravely concerned that replacing it with a new one is going to cause the same issue. For a phone that cost me an arm and a leg I wasn't expecting problems that I never had with any other phone.

Please help.

Thanks.

Hi Narada and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

When you are moving it around, is the proximity sensor staying covered? If it is being moved to the point where the proximity sensor is not being covered then this will cause the display to stay lit up.

I have also noticed this. I should be able to move the phone while speaking as I am not a statue.

Hi Sam. The first few days I didn't know where the proximity sensor was so I wasn't conscious about whether it remained covered or not. Then I read the manual and from that point on I've been a lot more careful but it still happens. I think one problem is that the sensor is shifted to the left side of the phone which makes it almost inevitable that it will become uncovered. I've also today turned off the 'double tap to turn on' feature and am testing whether that affects the problem. Will keep you guys informed. It makes me sad as everything else about this phone is perfect. I just can't talk to people with it.

Im also experiencing this problem too

I have turned GPS on bluetooth on set events in calendar and all sorts!!

during a call the phone NEVER lights up though so I know the proximaty doesnt get uncovered!

I have noticed it more when someone rings me rather then when I ring someone!

I'm also having this problem, taking and making calls from this phone is becoming a real nuisance as I am muting myself and putting people on hold multiple times during call. Please find a fix.

Hi Sam.

A few more details for you.

I recently purchased a 'Sony SBH-80 Stereo Bluetooth Headset' in the hope that it would allow me to continue using the Z2 that I love to make calls without the buttons being pressed accidentally. And it helped to some extent. But I noticed that when the phone was in my pocket during a call buttons got pressed anyway even when the screen is off. I would have to take it out of my pocket and unpress them and then put it back in my pocket with the screen facing away from my leg. And when I'm not making a call my phone is constantly trying to make emergency calls to random numbers pressed from within my pocket. All this is a real pain.

Also I noticed one more thing. When buttons get pressed during a call the screen does not light up. I'm watching the screen from the corner of my eye during calls and it remains black. But still the buttons get pressed. So my guess is that the screen is sensitive to touch even when turned off by the proximity sensor. Of course there are situations when the screen does light up sometimes and then buttons get pressed as well and this is because the sensor is too far to the left.

All in all having spent £600 ($1000) on the Z2 and accessories I'm very sad and disappointed that I cannot make calls. I would really appreciate some feedback from staff on whether you are looking into this problem and are looking to provide a software patch to make the screen totally insensitive to touch when sensor is triggered.

Thanks.

I feel I must drag this up again too

I have just been on the phone and managed to put the phone in to airplane mode which involves a lot of key presses to do!!

this ended the call straight away which I wasnt happy about at all

Are you using a screen protector? These used to cause the exact same problem on my nexus 4..

stu_m — Mon, 02 Jun 2014 20:42:49 GMT

a screen protector shouldn't have any bearing on this problem!!

Re: On-screen buttons getting pressed during calls

Narada — Mon, 02 Jun 2014 20:48:57 GMT

Hi, I'm not using a screen protector. I think most likely the problem is that the screen is still sensitive to touch even when it is turned off as made evident by the fact that buttons are pressed in my pocket and while proximity sensor is on.

I have a feeling this is related to the capacitive differences between this phone and others. Other phones don't respond to touch with any surface other than your finger. This phone responds to anything. Even wiping the screen with a napkin causing the home screen to move to the next one. The option to use with gloves in settings is also concerning. I hope all these features aren't the cause of this problem.

I just read on this link that the new software update (which I haven't received yet) has improvements in touchscreen sensitivity. Sam is this correct? If so this update may be all I need to improve things. Thanks.

have you got double tap to wake feature enabled?

I dissabled this and havent had the problem since!!

Re: On-screen buttons getting pressed during calls

Narada — Tue, 03 Jun 2014 20:08:52 GMT

Thanks Stu. But sadly I've got glove mode, tap to wake and smart backlight control all turned off. In fact I've pretty much turned off everything I thought I could interfere. It happened again today. Phone was in pocket. I had bluetooth headset on but call was ended with a beep which means it was ended by my phone. No idea what's going on. Anxiously waiting for software update. Sam any further details on whether the update is likely to help or anything else I can try?

I had the same today too I ended a call and sure enough there was a few things open and had to close them first!!

It must have just been a coincidence that it didnt do it for a day or two after I turned it off

dm841 — Wed, 04 Jun 2014 17:46:23 GMT

set double tap to wake screen in display settings and your problems should be solved

Re: On-screen buttons getting pressed during calls

stu_m — Fri, 06 Jun 2014 15:47:15 GMT

double tap does nothing

I have had it on and off and doesnt make a blind bit of difference!!

Hi,

In my new xperia Z2, the application(icon) listed second left in TOP row getting selected automatically and that application is getting activated, this is irespective of any application or any page (any home page or any application drawer page), after switch off the phone and on it is getting ok. again after some time same thing is happening.

once it is happening, even when i try to clse the application again it is getting activited and also if any selection is available in the opened application at that place it is gettiing selected automatically. other wise that particullar spot gets touch signal automatically with out any touch physically happening (I can call that as Ghost touch effect)

Is anybody else has the same issue?. Is it software or hardware issue
