mifzal — Thu, 03 Jul 2014 19:29:07 GMT

Im on z ultra c6833 with the latest version 4.4.4 updated 2 days ago with build number 14.4.A.0.108.
i found out that my proximity sensor does not functioning. The screen will not dim if i answered a call near to my ear.

I try to do this after read on other threads:
1. Go to your Dialer, and enter *#*#7378423#*#* to access the Service Menu.
2. Go to Calibrations
3. Go to Proximity Sensor
4. Choose "Calibration" and then "Start".

but in my case, i dont have the calibration button.

someone please help me? is it the software or hardware issues on my z ultra. ? is there fix to my issue?

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

I suggest that you try to repair the phone software using PC Companion..

Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.
How to backup?

If the issue should still remain I think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, contact your local support team.

Here is a trick i did for my c8633. I installed the APP called On Call Proximity. And i enabled it to lock screen on call (yes i gave permissions) and i made a call. Then i disable the option from app to lock the screen. Now it works try it.

Samuel, PC Companion, I have the latest version, does NOT have the option you say. and on 4.4.4 Calibration has been removed from the service menu.

So Sony has stuffed and I have a very annoying problem on my phone.

I make a call ... the screen turns off after dialling and does not come on until after the call has ended.

I can't end the call myself and I can't use the dialler for business answer systems.

Quite frankly, i have purchased a **bleep** useless phone. !!!!!!!!!!!!!

I have the same problem. During a phone call the screen goes black. I can't use the call options or use the dial numbers to select options.

This issue started once I upgraded my phone to 4.4.4 not only is the proximity stopped working but all sensors like phone tilt and everything stops.
U can check this with cpuz utilty once the problem starts under sensors tab it will display nothing.
