I have purchased Redmi 4A 5 months ago and I am mesmerized with the phones performance. Till now I didn’t had any lagging issues with the phone. It has a good build quality due to plastic body. It weights very low due to plastic but very much durable. Look and feel wise I don’t think you will get a phone better than Redmi 4A under the price range of 6k. Now, coming to the user interface its very much user friendly and a value for money for those who are looking for a good 4G phone with a very good battery life. I am using both the sim slots and never had any signal issues or sound issues with it. The loudspeakers are quite louder and very much good for the media consumption. The only thing I don’t like with this device is its old marshmallow 6.0 OS. Mi is very slow in updating its devices and its a big worry for a person like me. But that’s the only Con I have felt with this phone, otherwise its very much good device to use.
