Over enthusiastic to disable many distracting apps on my Sony Xperia U (ST25i) I went "settings>apps>all" and disabled away. Where no disable option was available, I clicked on force stop. With Bluetooth Share I stupidly took it to be a social networking app and disabled it, later force stopping it. Dumb, I know, but how do I get it back? I'm fairly new to all of this, obviously, so please be very specific in responding. Many thanks.
