I have a really weird isuue with my SP.
Since last night, it started to vibrate non-stop. For the whole night, and it is still vibrating now, even if it is turned off.
I did a factory reset and it failed to solve the issue.
Also I have tried to repair with PC Companion, failed.
I should probably add that 1 and ~2 weeks ago my phone suffered some water damage. I fell with it in the sea. I was keeping it in a thin fabric bag, and it got wet. Not very wet, and I immediately turned it off and let it dry.
It worked well. Until 1 or 2 days ago when I noticed some short random vibrations, but I didn't think it was that bad.
And now it is vibrating constantly.
