Xperia P unreachable in standby mode

[sp]

Hi,i have some issue with my XPERIA P

After a standby mode , i become unreachable but signal bar is full,i'm also not able to perform any call...everyting look like to be ok.I need to switch off/on my phone or enable/desable the airplane mode to fix this issue.

It mostly happened if phone is  in standby mode for longer time(always seen when i wake up in morning).

Android Version:- 4.1.2

is there any solution?

Thanks in advance

Problem solved for temporary basis.

Developed an application for the issue.

If phone on standby mode for more than 90 Minutes, application enable and desable the airplane mode to fix this issue. So I am not missing any call/message now.

So will use this app till Sony did not fix this bug.

Thanks
