Well all I can say is that my phone updated with only one prob. You could not here any one after making call. Quick Fix . Soft reset fixs a lot of prob. In case you don't know how to do this . Very easy remove batt. with out shutting down phone,wait 1 min then put batt back in & power it up . Fixed my prob. Very Easy. I love it all works great Nav,Send Text ,find gas & Love the Flash seeing lots of stuff now!
