Just got mine on 7/8 after years with iphones. Needed the bigger screen, wanted a better camera - you know the drill... But already I'm experiencing the issue others have reported: try to make a call, phone says dialing. Others call in, go straight to voice mail. I can text, facebook, message with facebook. But, cannot use the actual phone. Restart, power off & back on several times... It's hit or miss. does this happen to many folks? Should I return it?
