The other day the vibrate on my phone just stopped working out of nowhere. the haptic feedback, notifications, calls, anything just will not vibrate. i've checked every single possible vibrate box there is anywhere as well as tried to turn the phone on vibrate just to check and nothing. any ideas besides a hard reset? also what will a hard reset do? what all will i lose? i'm thinking apps, any pictures not on the sd card kinda thing? i wanna take it to the sprint repair center but there's always a problem getting down there so i'm trying to see if i can fix anything myself.
