It's so strange... and it happens about 4 times/day on average... but I have started receiving random phone calls from strangers all over the country who aren't even dialing my number... as in the phone will be in their pockets/purses and it just automatically calls my phone number. I have long messages on my voicemail from people where all I can hear is background noise because they aren't aware their phone has called me. I always call people back and they say they don't know who I am and didn't mean to call me. I have talked to a lady before who said she was using her flashlight app on her iPhone when hers randomly called me... It happens at all times of the night/day... I called AT&T and they gave me the deer-in-the-headlights look... So I'm at a loss for explanation. I've got the Galaxy S3 and just got my 512 area code (Austin TX) cell number activated. It's been doing it ever since. I can't change my number because it is linked to my business and there are clients who have my number... So yeah... does anyone know anythiing????
