Hi mypapaiscute12,

Welcome to the community,

Does this happen on every occasion or is this random?

is it stuck? check around the ring if there is something. has it been this way before?

try to have your phone checked by your local service center as this is a hardware issue

contact Sony xperia support to get it inspected.
