I would like to ask how vivo phones communicate with each other.

How to use vivo for mutual transmission: Find "mutual transmission" on the desktop-select "one-button switching" or "transfer files"

One-button change: select "I am an old device" or "I am a new device";

Transfer file: select "I want to send", "I want to receive", "iPhone transfer file" or "Web transfer file"

Connect the device to be transferred, and select a file or application-Send.

Note: this function requires both parties to turn on the function, and the other party's equipment can be seen in the pop-up interface.

If you still have more doubts, you can enter vivo official website-My-Online Customer Service-Enter labor and consult online customer service feedback.
