I bought this on Amazon 1 year back according to the performance it works well.By considering price, design, camera, performance it is better because it has kirin 655 octa core processor.
Negatives: 1)when you open bluetooth mobile will struck 2 minutes and then automatically restarts.
2)when you uninstall any app a message will be displayed on screen as "Drag empty space" then no any option works.At that time you must press and hold lock screen button and then reboot the mobile.
