I have been using Samsung Galaxy On 7 Pro since last 3 months.I love watching movies and gaming and what I have observed is that while watching movies( offline ) the phone was 96% and after 2 hours it drops to only 23% .And not only this but when I played games it just shutsdown.I also showed it to the samsung smart cafe but they said everythings are okay.Its sound quality and power is okay.It is easy to use but I dont think it is that durable.It also has many functions. But has no good value for money.
