[Sony Xperia S, Acro S, Ion] msc3:
My phone often restarts, always when i'm using phone in area with poor network coverage. I sent phone to service, they changed MB to a new one but problem still exists... Wiping, repairing via SUS doesn't work. I observed, that this problem never exists on 2G network, only on 3G while data transmission is on, and HSDPA signal is weak or when phone switches form HSDPA to 2G.

Android 4.0.4

6.1.A.2.55
