Huawei's nine-fork pro's mobile phone bounced as soon as it sent a message. How to copy and delete?

Huawei's nine-fork pro mobile phone bounced as soon as it sent a message. Copy and delete are clipboard. The reason why mobile phones always pop up and paste is because the relay function is turned on and other devices are pasting things. To solve this problem, you must first select settings here. Then in the setting interface, select the general option. In the common interface, you can see the options of air play and relay. Then in the interface of broadcast and relay in the air, you can see that the relay is on. Next, as long as the relay option function is turned off, the problem that the mobile phone always pops up and pastes can be solved.
