The quality of this smart phone is very very good. But the genuine reason of not buying it is of inserting of sim card and memory card. That is it has two slots on one slot only single sim can be attached but on the second slot either you enter a sim or a memory card. People used to insert mainly two sim and a memory card.
So I must say see before buying it or choose another phone.
Appreciation is
This have high sound
Good battery life
4 gb ram
64 gb internal
So mainly you won't insert memory card
Thank you
