If you are thinking to buy a budget phone then blindly search a date of next sale of xiaomi redmi note 4. I am using this redmi note 4 ( 4gb) variant since 3 months till date no laginnes is to be seen in the phone the ram management of this phone is realy very good. All the heavy games like asphalt 8, fifa16 runs withouth any interuption. The camera, processor, fingerprint sencor and every other thing works fine.
