Actually it is very similar to redmi 3s which is priced at 6999/- Redmi 4A priced at 5999/- 1k difference between then. So let me tell you wat are the differences,
1st would be the processor redmi 3s has snapdragon 430 chipset with adreno 505 Gpu Where redmi 4A has 425 chipset with 308 Gpu I must say redmi 4A performance would be low compared to redmi 3s
2nd one would be camera Redmi 4a has 13mp with f 2.2 apeature and redmi 3s has same 13 mp bt it has f 2.0 apeature I must say redmi 3s camera perfomance would be good.
3rd one Battery redmi 4A has 3120 mah where as redmi 3s has 4100 mah but company says that Redmi 4as battery can last upto 7days of normal usage thats really amazing, there is no smartphone in this price range can be expected.
So in 1k these are the differences, its upto u which one u wanna go with.
Sorry guys it has a plastic polycarbonate unibody finish.
I would suggest u ppl to go with redmi 3s.
