I am using this phone and the sound quality of this phone is awsome and the video quality is also very awsome , People who use it for a first time face some complication in operating this phone but after some time or days it becomes easy to use this phone, the design of this phone is very attractive if you are talking some on call by this phone it looks fabulous and I have space gray colour so that it looks very official and attractive , the network as compared to other phone is stronger and the internet speed is also awsome in this phone, after charging it for one hour its battery backup is about 6 hrs for me it depends on your use , but it is too costly so that the person who is willing to buy this phone if he or she does not have that much amount will not able to have its benifits .
