OPPO can only use scene tags as follows:

Step 1: Enter "Settings"-"General"-"NFC"

Step 2: In " Select "NFC Scene Tag" from the NFC" menu

Step 3: Select the scene tag option that needs to be set/modified. Here is a demonstration to set the NFC scene tag to silent mode (open), then click "Mute" Mode" icon

Step 4: Click Edit next to the "Silent Mode" icon to set the switch state. Here we set it to the on state. After saving, return to the previous interface

Step 5: Place any of the randomly given NFC scene tags close to the back cover of Find 5. After a beep, "Tag written successfully" is displayed at the bottom of the screen. At this time, writing of the NFC scene tag is completed

After exiting the setup program and returning to the desktop, place the NFC scene tag that has been written with silent mode on close to the back cover of Find 5. After the sound prompts, you can see that it has been switched to silent mode. Of course, NFC scene tags can also be written to open a program on a certain mobile phone.
