All Android11 models

Countermeasures/Statements:

Sorry to bring you a bad experience.The function of automatically switching light/dark mode at sunrise and sunset will dynamically switch between bright and dark mode according to the real-time sunrise and sunset time of your current location.Therefore, network and positioning permissions are required to detect the sunrise and sunset status of your current location;if the function does not take effect after the function is turned on,please check whether the network service and location permission are turned on.If not, please pull down the status bar to turn on the network and location service,wait 3 -4 minutes and turn on the screen again, you can find that the system has switched to the light/dark mode that matches the current time.
