My s2 has started randomly switching itself off. It happened first thing this morning, could be a concidence but a few minutes after switching it back on it did an auto update from 4.0.3 to 4.0.4. During the day it has switched itself off about 3 times.
Can't get it back on without removing and replacing the battery. As I write it has just re-started on it's on. Would appreciate any advice. (phone not rooted)
