I am personally using this phone since last 2 yrs. All I have to say is, this is a BEAST! Received 2 Android upgrades so far since my purchase and no lag what so ever. I(my family) have a Samsung Tab, Iphone 5s, HTC One X+ and LG G2. My vote goes to G2.(Sorry Iphone users).
LG’s user interface is one of the best. I believe its better than the Samsung’s one. Again, Use it to Believe it. Thank you LG.
