This a a best phone in 16000. It have 16m colors of good resolution having 1080×1920 pixels( 401ppi) . It has Octa-core 1.6 GHz processer. Primary ca. Era is of 13mp and secondary is of 08 mp. Battery is of 3300mah. This is a Samsung phone so no problems in this phone good in all around looks cool. But the bad thing is the price.it is too much in price.As J7 prime user I will advice you to go for it. It is reliable, durable and simple device which will last for at least 2 years. Also you will get good support from Samsung. As for Lenevo devices, they have lots of issues reported by genuine users in many online sites. Last but not least they have very high SAR values which is very bad for health. Personally I use a Lenevo tab and I am happy with it. But I will not but a Lenevo smartphone in any condition.
Anyway if you think J7 Prime cost too high. Than you can try Honor 6X which is value for money and a has better specs. Also it is now available on Amazon with open sale. And RedMi Note 4 is great option, but getting it is like a winning a lottery. Regards.
