Redmi 4 64GB is the first mobile which I purchased on my interest, I brought it with a suggestion of my friends come on a product which I heard lot about this, the mobile is light in weight and easy to carry music player works beautifully and sound is audible and clear, 4 GB RAM and 64GB ROM is excellent for in 9500rs mobile, but mobile RAM is usable only 2 GB in this, read all used for applications and a fault in a microphone, which does not works good at any time, while calling if we take slightly away from our mouth the microphone doesnt work at all which is bad to say, and some features like dual apps, second space and sensors are good enough but dual apps strucks and doesnt work properly and sensor are not working properly, battery of 4100 milliamps is good, design is simple, could have been better, looks simple and feels good in hands, overall a value added product under 10000 rupees, camera is good in the lights and doesnt hold good in nights, selfie camera is good enough mobile with all these features can be a user friendly when it works correctly, but with small changes in mobile can be a effective product, and battery temperature will become hi during usage, I suggest you to stay away from this, since the battery heats heavily.
