Rv mobitech phone has been taking big steps to make the rv smart phone platform more theft-proof. Smart Device Manager - which lets you remotely lock, ring and track your device - went some way towards doing this, but it's only with the 5.1 Lollipop update that a full-on kill switch has finally been implemented. To activate it, you need to enable 'Device Protection' on your device. Then, should your phone get stolen and factory-reset, the phone will require your Google account details to let another person use the phone. This will work similarly. to Apple's 'Find my iPhone' feature, which reportedly led to a dramatic drop in iPhone theft in New York, London and San Francisco.
