LG G3, LGEs flagship device and most probably one of the best Android devices of 2014, competing equally with Sony Xperia Z3 and HTC One M8, Galaxy S5 was able to reach a little bit with it, but with the arrival of Galaxy Note 4, users have lost their interest in Samsung and now moving towards other OEMs, and what best to switch to than LG. Like its predecessor, LG G3 is dominating the market, despite we don’t heard much about it, yet it is sold with an extraordinary Number in Market. Same Like it predecessor, LG G2, LG G3 is quite fast and smooth, far better than Samsung, as their TouchWiz lags a lot, even on device like Note 3 and Power Horse like Galaxy S5, you will experience a little lag, but on LG G3 only thing you’ll experience, if you switch from Samsung to LG, is its Weight, its a little heavier than Galaxy S4 or Galaxy S5, which is something that I love to own as it gives you a feel that it is still in your Pocket.
