Do any of you have an issue where the phone screen turns on and off (and beeps) when it reaches 100% charged using a Qi charger? I am using the official Samsung wireless back cover with a Nokia Qi charging pad. When the phone reaches Charged, it will turn the screen on, then it'll say Charging Wirelessly 100%, then it'll turn the screen off and start charging... and the cycle repeats every 20 second or so. Anyone else?
