I did bring a fortune to have a smartphone anyway exceeded in 2 years but I still wanted a powerful device at the lowest cost. This smartphone is excellent, very easy to learn, top picture quality as well as GPS. I had read some reviews about the battery but it takes 3-4 days to widely use of 2-3 hours / day so satisfying. I advise you this smartphone if you do not want to pay the price for having a Formula 1 but have a very complete device.
