Samsung galaxy J7 prime has price of 18, 000
You can just buy two redmi smartphones with same features.
It has 3 GB ram but it only gives you 2.1GB to use.front camera us good in natural light at outdoor codition but in indoor camera quality is bit low if lighting is not very bright.
In first 2-3 months phone runs quite well but after that when you install too much apps it will start to getting lag.
Battery capacity is 3200mah so it is not very good to say about it can run for one day.
In the end instead of wasting 18000 on this you can go for some other devices like redmi note 4 or coolpad cool 1 ( it has 2 back cameras of each 13 mp)
