I brought samsung j7 for me after trying lenovo vibe and I should say that it is the best purchase have ever made.
*Battery Backup **It has a very good battery back up and it charges very fast. As I observed it was charged from 18% to 49% in just 15 minutes.
*Screen ** Its screen size is very good and very handy.Its screen glass is scratch resistance and very strong.
*Sound ** It has a very good sound quality. Phone calls can be heard in heavy traffic and even on bike too.Listening to songs is very enjoyable.
*Looks** It looks very cool especially the gold edition is the best edition I have seen and purchased. It has a glass sleeky body which make it shine more and more.
*Overall Perfomance* Its overall performance is very good. It do not heat up, battery do not die easily, looks good in hand. It is the best budget smartphone I ever had.
