proximity sensor issue

[spiralz]

My phones screen won't come back on after making a call seems to be a proximity sensor fault.

As soon as I press the call button the screen goes blank even if it's not against my ear. If I press the power button it will come back on and then stay on even if I then press it to my ear.

Very annoying to be honest and I can't find a setting for it

Thanks

I have a problem where the screen is turned on during calls which makes me press things I don't want to.

The proximity sensor it self seems to be working (tried Xperia Diagnostics)

Any one have this problem and/or a fix to it?

Try the basic, repair your phone with

Update Service (SUS)

PC Companion (PCC)

Bridge (for Mac)

Alternatives on How to backup Xperias

I did that, but no change in the behaviour.

I just noticed the following. If I cover the sensor before making the call, the screen turns off when I press call, and comes back when I remove the cover.
I however can not make the screen turn off once I have removed the cover.

So the sensor seem to work, but not as it supposed to in the dialer app.

You might have to take it to a Sony repair center, sorry.

Hi -

My screen was not getting on after making the call so I wanted to check the service menu. I typed *#*#7378423#*#* and accessed the calibration menu and selected Proximity sensor menu. 

It showed Autoscreen Brightness On and Proximity Switch OFF. I switched Autoscreen Brightness off (other wise the calibrate option is grayed out) and tried to calibrate the proximity sensor. I got the error -99 and the message that it cannot be done.

1. How do I switch on the Proximity sensor on
2. Will the calibrate option work if the phone is factory reset (there is a message which says - Pls factory reset the phone before calibrating).

Thanks in advance.

I bought this phone and regularly i have been facing some issues

1)screen goes completely black and i have to restart

2)tick tick noise in earpice while on call

3)some other problems associated with proximity sensor(eg screen turn of the moment i cal someone even if sensor not covered and sometimes never turn on until i restart.

kindly tell me these are hardware issues or software ones and wud be solved with firmware update. Currently i have 14.1.G.2.257 installed. These problems have reduced a bit but still irritate me after every 2-3 days.

Kindly tell wat shud i do. I dont want my set to be repaired so early. Its just been a week i bought this frm sony exclusive showroom..

Hi,

I have just bought my Xperia Z1 2 weeks ago (25.10.13) when I have received incoming calls and just after I push the answer button or when I make outgoing call just after I push call button screen becomes black till to call ends or till to I push to lock-screen button. Even I remove my phone far from my ear it still black screen. In first days I don't have any kind of problem like this. But last 2 days I have this.

Can you please help me about this issue.

Kind Regards

Do you use any screen protector or protective case on the phone that covers the proximity sensor?

That could trick the phone thinking its always kept to the ear blackening the display right away during calls.
