I am using this device since 2014 and I am very happy about it. Sound system which is used in the device is boom sound it is really good experience. Headphones just work as professional’s. Screen size is pretty good which is 5’5" with HD display. The things I don’t like about phone is that it gets heat up very quickly. Storage space in phone is only 4GB which is very annoying. Battery gets drained very fast.
