I used this smartphone few days back.
Yes its true that is it have many facilities as compared with other smartphone in the market. But once public realised any drawback of that smartphone then same news spread in that localities. Which turn into bad impressions of that smartphone company.
because of its back camera is not work properly.
Also.its battery backup is not so good.
Hardly 7 to 9hour its battery goes.
Still the improvement is required in battery backup.
