I write my opinions about xiaomi redmi 4. Mobile is very good under Rs 7000 price. Mobile performance is good, has a 1.4 gigahertz Quad Core processor and 2 GB of RAM. Very good battery performance. Has a 4100mAh power battery. Mobiles both cameras are good, rear Camera is 13 mp + front camera is 5mp. Support 4G Bandstand also a VoLTE smartphone. Xiaomi redmi 4 has 16 GB of internal storage and 1 to 8GB expandable memory. It is not possible to use two sim cards and a SD card in redmi 4 at a time because has hybrid sim slot. But overall the xiaomi redmi 4 is a great smartphone under Rs 7000.
