I had a smartphone from the Japanese brand in mid-range and it is day and night! Proper package. Untested audio accessory. I regret that the charger is not a detachable USB cable (one star less for that). Good finish is plastic without being cheap. The quality of listening on telephone conversations is good. Top untested Speaker. Screen: super, size I wanted. It will be small for techies today. I find the contrasts very satisfying. He is quick to see very fast, the picture is actually correct with known limitations but I will not complain. Navigation is good especially with 4G, visual comfort being what it is for a screen of this size. Battery: lasts up to four days if you disable 4G four days !! This is 2x my old phone. Interface: clean, without bogus application. After 15d / 3d weeks of use, and some applications installed I feel a little less swift but nothing insurmountable. This is a good smartphone for a minimum price and a brand that gives me confidence!
