I buyed this phone in november 2018.According to look this phone is better. Screen resolution of this phone is 720 × 1480 pixels.It is strong eg. Even when you put wait on it there are too less chances of its breakage. Battery backup is 3300 mah i.e battery backup is better from the previous model j6 which had battery backup of 3000 mah. Battery of this is non removable. RAM of this mobile phone is 4 gb. It has internal memory of 64 gb and external memory i.e. expandable memory is 512 gb which is too much.It has audio feature of dolby atom which is unique function of this mobile phone.Camera quality is also better according to its price.Its back camera is dual camera. It has 12 MP primary camera and 5 MP rear camera. Front camera is of 8 MP. Flash light is available at both of the sides.Unlike j6 it has fingerprint sensor location at side where power button is available. Other sensors are Light sensor, Proximity sensor, Accelerometer, Gyroscope. It is a better phone. U may try this phone once
