Gionee m2 is an average device to use.My mother is using this device from atleast one year.The performance of the device is an average. The battery is 4000mAh which is quiet impressive and gives 2-3 days of battery backup. The phone is too heavy. The screen is not so good and the side view angles are to bad. Both the front and the back camera are having too bad quality in both the day lightning and the artificial lightning. The built quality of the phone is not so descent. This phone is only best for those users who requires a long battery time .I don’t like Gionee m2 although rest of the phone is below average .
