This phone was launched with good features in affordable price after waiting of some time, I buy thi phone but after use if this you will be miss some features in this phone like * phone rear camera is very bad, NON-REMOVABLE BATTERY, notification light is not in phone and netspeed is slow, android 5.0 is installed, however unite 4 and 4 plus ( recently launched) had 6.0 marshmallow, both sims doesn’t work in 4g simultaneously, finger print sensor is in back side not in front ( automatically stopping finger swap, when u put it ur pocket it will touch again and again in ur pocket even ur screen is of by power button, and says u have many attempts) , I THINK IT IS VERY USEFUL REVIEW TO YOU BY ME BEFORE BUYING THIS PHONE, THINK TWICE BEFORE BUYING.THANKS.
