Hi,

I have xperia M handset.

Its setting menu got locked automatically without applying any app lock or anything. Now its not opening and askin seciruty password to just open setting menu.I am not able to handle any settings. In mid way sometimes it opens and again after some time it's asking security code. Pease give me solution as early as possible.
