Hi guyz I am using this phone as my primary device.and I want to share you some information about this smartphone. Lg g2 is a single sim device which comes with 3000 mah battery and full hd 5.2 inch display and the best part of this is the display while you watching movies it is very sharp and very crisp. Although is has very longlife battery which charge very fast.and it has infrared blaster which can control your tv, ac, home theatre, etc, only the con of this device is you cant expand memory using micro sd card
