Positing for a friend of mine... Her (non-rooted) Design, since upgrading to ICS OTA is having a few issues, mainly: 1) Running very slow/laggy 2) Battery has been draining much faster than before 3) Camera shutter sound is even more annoyingly louder (even with everything on silent) Anyone else having the same issues? any solutions? (other than rooting) I heard doing a factory reset fixes the slowness, but from other reviews, it seems to be a 50/50 shot, so she doesn't want to do that unless no other choice. Thanks in advance!
