I think that j7 prime has good bulid quality means that cameras both ( front and back) are awesome but it doesn’t have any image stabilisation sensor but that’s not end means that j7 prime has full metal body and also have 3GB of ram paired with exynos 7870 having 8 cores and clck speed at 1.6Ghz But only 16GB internal memory and is worth Rupees 16000-17000 .j7 prime also lack in display as it has TFT display of 1080-1280pixels and even also lack in some important sensors like Gyroscope, Magnetometer etc .So, this mobile is not giving such high performance like other devices under RS17000 but u can still buy this as I’m using it from 3 months and samsung has given all the new features in it like all Microsoft office apps , samsung s bike mode, s scecure and others new ones also and this mobile also have a fingerprint sensor on the homekey and that also provides more security but after the whole conclusion I am not happy with this phone as it has premium look and anyone can’t consider it as a value for money but it is a durable and handy but not for one handed user.
