Failed to open Camera

[KishoreXperia]

My Xperia M dual (C2004) often showing failed to open camera. Problem was very less, now comes very often after update to latest Build 15.2.A.2.5.
N.B. I am using default face unlock. So this problem makes irritated.
Only restart solves this problem(any shortcut for restart will b appreciated as there's no restart option in power menu)

Thanks in advance.

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

I recommend that you first try your phone in safe mode to see if this might be caused by one of your apps. See this thread for information on safe mode:  http://talk.sonymobile.com/t5/FAQ/How-to-boot-your-phone-into-safe-mode/m-p/348008

If this also happens in safe mode i recommend that you make a repair of the phone software using a computer and Update Service.

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.
