I bought redmi 4a some time ago. All other features are good but Its battery battery problem is very bad. It charges slowly and gets heated whenever I use it. I goes to care and they update its latest software in it but after that the problem was same. So I sold it and buy another phone redmi 4. It is quite good phone and have more features than that of redmi 4a.I suggest you to buy redmi 4 instead of redmi 4a.
