"frequently restarts for no apparent reason," Doesn't happen to me. Not argueing one way or another, just stating a different experience. I once had a Sony Xperia, bought the same model as my then-girlfriend, from the same company, probably the same batch. She had often spontaneous reboots, but I never had. She complained quite much about that and would never buy a Sony smartphone again.
