How does oppo R9 shoot slow-motion video?

There is no mosaic, there is a picture.

(1) Open the OPPO phone, enter the desktop, click on the software store that comes with the OPPO phone, and then search for "Great God TV" to install it. This is a very good screen recording software for my own use.

(2) After the installation is completed, open the application, click the cross button below to select the "recording" function, and enter the recording interface. Remember to grant permission.

(3) Click the vertical screen to record, and a floating window will appear. Then click the start screen to start recording. Permissions for floating windows can be found in the mobile phone manager's home.

(4) After the recording is completed, you can start editing the video and upload it for sharing.
