J7 prime comes with 5.5inches TFT screen, 3gb ram 8mp primary and 13mp secondary camera.coming to the sound quality this device has got really good sound quality comparing to other samsung devices even there is change in the location of the speaker.heavy games got stuck easily so this is not a good gaming device video quality is good as screen is not superamoled its TFT FULL HD but quality could have been better if it was amoled battery backup good as its 3300 mah battery as phone get charged quickly but there is no quick charging option. Coming to fingerprint scanner it doesnt recognise my finger several times so I m not using this option but I bought this phone due 3gb ram and fingerprint option overall I would like to give 2 star
