I have a w910i black (for some reason it makes a difference) and yesterday it decided to not send messages or make calls, originally i thought it may be my netwrok (orange) but after asking a friend who's on the same network they said that theirs was fine (same phone as well)
then in the afternoon while i was trying to text the phone turned itself off
and after that it started freezing while texting.
I rang orange and they changed the settings from GSM/3G to simply GSM so i thought great it would work.
But now the phone keeps 'freezing' by that i mean it stops half way through texting and then after 20-30secs it will let you text on.
I have also noticed in the last few days the phone seems to be running alot slower and takes alot longer to open up the menus and general things.
Does anyone have any ideas what could be wrong?
