Redmi note 4 is a very good budget phone. Its simply an upragaded version of redmi note 3. But it is too much better than note 3. Camera is not good in note 3, but when comes to note 4 , the camera is too good. Photos are crisp and clear. No yellowish pictures. Sound is also good. No heating priblem. Style is too good. It look like its an high ending phone. Oh actually it is a high ending phone with budget price. No doubt go for redmi note 4. It will be a perfect choice.
