I am using this device since a year and it started hanging a lot and I feel it is one of the bad device I had used in my entire life. it has many problem like lack of many useful features.
It has average sound quality and it does not record voice clearly and sometime I get difficulties while having call in its sound
It is not stylish and its design is similar to other devices and I do not feel unique while having it in my hand so personally I do not like it's style and design.
It has not many useful sensor. it has very bad camera of 5 magpixel. it started hanging while playing game and various type of features are not given to this device.
My personal opinion is that not to take this device otherwise you will feel that you money is lost.
