Also you should think that which device give you a real 4G experience(1) Micromax Spark 4G(2) LYF smartphone
I know that you got your answer.Now lets talk about its features:
(1) It comes with 4G VOLTE which is not give you a real 4G experience at all.
(2) Its sound quality is very bad like a china cheap device.
(3) Its ram is very low so it maximum time suffer with hang.
(4) Its looks very cheap and also not look good in hand.
