I use it before 2 years ago but it is work proper, ultimate battery backup, sound is good in headphones but loudspeaker is best, it is too easy to use in 5.0 software of andriod, its style or design is too good slim easy to carry, In this range of mobile all the features are add in mobile and easy to use all the features, full money back of this phone, in this time my phone is best too good for me in all.??
