The first cons is the heating issues or problems under gaming for longer than 15 minutes continuously.The battery capacity of Samsung Galaxy J5 is below average, It comes with less number of sensors, It has small RAM of 1.5 GB only, It has quite small 8 GB ROM, keeping track the phone temperature is impossible as the temperature sensor is absent, It does not contain water & dust resistant and it does not include Java .Sound quality is not so good.Style and design is fine.It doesn’t has high range features.It does not support HDMI. The display is not Full HD.There is no any LED notification light which is yet another cons or disadvantages. Next Samsung Galaxy J5 – 6(New 2016 Edition) cons is the absence of fast battery charging technology. Recording videos with it is a bit annoying as the camera is very shaky because of the absence of an optical image stabilization.No any scratch resistant glass like Corning Gorilla Glass or Dragontrail Glass.Reliability and durability is also not so good.No value for money, Don’t buy it.
