1. The driving mode of mobile phones is mainly used by drivers. When driving mode is turned on, a car logo will appear on the notification bar of the phone. There will be corresponding prompts when sliding down the notification bar: if there is an incoming call or new text message while driving, it will be automatically read aloud, without requiring the user to use both hands and eyes to view the operation.

2. The entire driving mode interface also integrates common functions such as navigation, phone calls, and music, allowing users to choose to enter clearly and quickly.
