Even with the best precautions, your smartphone can still go AWOL on you. Two options: you're so absent-minded, your friends call you Professor, and if your smartphone were the only thing you've been losing with alarming regularity, life would be beautiful. The other options: thieves like you. Whatever option, it's good to avail yourself of "erase" and "remote wipe" options.You can erase the contents of your phone if it's lost, stolen or if someone has been trying to log in without success.
