Samsaung Galaxy J7 which I have been using for last few months.It is a beautiful and efficient product.
Its display is very good.
Its sound quality is a little bit low but it will not cause any problem.
It has 1.5GB RAM.You may have to change the set after two and a half years.
It has very good picture quality and its camera is also very good.
The battery runs for 24 hours for normal users but for massive users it can provide 16 to 18 hours of battery service.
Samsung Galaxy J7 is the best for those who want a branded mobile phone within average budget.
It is very efficient in colour creation.
You will have ball with this.
Really a very good product.
