I buy a Redmi 3s Prime phone it is such a lovely phone I like it becous it has 3GB RAM and 32GB internal memory. It is Double sim 4G mobile. But I’m not satisfy with the double sim slot becouse there is one option to select put sim or memory card in 2nd slot of phone.
And battery is in built the phone it is not removable. There is a pin key to open sim slot.
The Sound Quality is more attracted.
There is a Finger print sensor on back site of phone it is most attacks
