I personally check speed test between Moto X Play and Samsung J7 but find that Moto X Play performance is much better in each section including browsing, gaming, multiple apps running.
Moto X Play is the clear shot winner.In performance Moto G 3gen is better than Samsung J7.Samsung lags many times. Networks 4G working suddenly change like2G after never change 4G phone restarts agen change 4G otherwise all Oki brand new samsung agents warantey
