Just started doing this Friday after some of my apps updated & google was one of the apps that did update. Only reboots when someone in my contacts calls me & I have the audio ON. If I have it on vibrate it works normally, If I have the audio on everything else works perfectly except when someone calls me it rings once & then reboots the phone. Caller shows on display for a second, phone reboots but after the phone reboots there is no record of the call in the call log either. When it's on vibrate the phone works same as before. Verizon is my carrier.
