Hi
I have never done an android update and I have a few questions about doing them.
An update for my Vodafone(but on 2 degrees) HTC one sv(4.2.1) for android 4.2.2 has just came through.
If I do this update, does the phone reset to factory settings?
Do I need to back everything up?
I'm typing this on the phone concernd so appologies for spelling, or incoherent sentences.
