I have been using this app since 2 month and now it has become a tragedy of my life because whenever I use internet it hangs.it’s touch does not work properly.When I listen music suddenly it is stopped and again it hangs.it does not have good camera quality it’s rear camera is so-so and it’s front camera is wrost.These are major problems and fault of this mobile phone.it’s design and style are so-so and range of feature is bad.the only thing I like about this wrost mobile phone is it’s battery backup it’s the only one thing which I liked other wise it is wrost mobile which I have ever used.
