Redmi5A, is the best phone in terms of cost. The features are quite amazing, if u compare the phone with its price, I recently bought the phone at 7000 rs, when available at local market. The phone has a good processor with 3gb ram and 32gb internal storage, although it has nothing new and is just like redmi4 except camera and performance. The camera quality is not good, at daylight the pictures clicked are quite good, but at low lightening conditions the camera is worse.
The sound quality is just good, not very good. Finger print sensor is not available. The phone is very light weight and slim. And looks are quite good, so I will not recommend it to someone, but its a good low budget 4G smartphone, to enjoy all the features of a complete phone.
