On-screen buttons getting pressed during calls

[Narada]

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.

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

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!! 

[Narada]

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

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

[stu_m]

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
