I have been using this smartphone for one year I did not find any problem with it but after one month I saw the camera was in not good condotion then I desided to go servise center and I ask them for things and they said ok you give us your phone and we will solve your problems but I Did not gave them because its really needs time but now I say its one of the best smartphonr in the market if you can forget about its network and camera problems.
