1. When the mobile phone can't apply the avatar, you should first consider whether your mobile phone supports the avatar function.
2. If the mobile phone supports the application avatar function, confirm whether the switch of the application avatar of the mobile phone is turned on. You can go to mobile phone settings-(applications and permissions)-open the corresponding software avatar button and try to use it.
3. You need to use the standby desktop with built-in system to support avatar. Using third-party desktop software will make it impossible to use the avatar function. If you use third-party desktop software, it is recommended to uninstall and try again.
