It is the only phone I think with so many features and less price. I bought this phone 8 months back and greatly satisfied with it. Battery back up is superb. No need to download app lock. App can be locked in settings. Finger sensor is good from the day I bought it till date. Easy to use phone with smart features. There is a separate play store of mi. The design and style of the phone is very attractive. The sound reception is also very good. It worth the money it costs. My suggestion for the people who want to buy xiomi redmi 3 will b yes definetly buy it. Ull definetly be satisfied with it.
