The mobile runs superfast with1.6GHz octa-core it comes with 3GB of RAM. there is no hanging problem like other samsung mobile.3300mAh non removable battery keeps the phone charge a full day. 4g supported with LTE having Sensors on the phone include Proximity sensor, Accelerometer and Ambient light sensor. camera is good with 13 and 5 mp. if we think about the price then I feel it is slightly more. sound is best only with earphone. overally this is a goof phone to buy.
