I can’t say I had any complaints about this phone. I wanted to try out a bigger screen and so gave this one a try. I must say coming from a Galaxy S5 this was a different feel. I did like the size, Ram and storage. I also liked the knock feature. For someone looking for size, features and speed-this is a good phone. I liked the camera but I couldn’t get over the issue of going from 16mp to 13mp. It took good pictures but I still liked the 16mp of my galaxy. I eventually sent back a very good phone and opted instead for a Note 4. But by no means is this a bad phone-it’s a great phone that’s worth trying out.
