What does the icon that looks like a leaning man with arms outspread do? What about the rest of the other 2 icons do?
The first one looks like a hypo also. I thought it was a rotation lock but it doesn't seem to have any effect if I tap it (regardless of the position of the hard switch on the side).
--> On/mute micropohne
--> Lock home screen
--> On/Mute sound volume
