Default [Q] Camera problem ViperSC2 5.1.0 Sensation XE

First I'd like to apologize if there be a same question asked before, but i couldn't find it so I am asking.

I recently upgraded from ViperS 5.0.0 to ViperS 5.1.0 on my sensation XE. Viper 5.0.0 has no issue whatsoever but after upgrading to 5.1.0 i am having a problem with the camera.
I click on the icon, the camera app opens, for a couple of seconds (it seems as if its hanged as i see the settings/buttons icon of the camera app but the screen is black) and it closes.

I'd be glad if you could answer my queries.
