But maybe it’s too big to be used on the desktop. < / P > < p > the widget adds privacy controls: for apps that need location information, a window will now pop up asking if you want to allow the widget to use location data. After activation, the widget can use location data for up to 15 minutes, and the location service privacy settings of the application now have the widget option. < / P > < p > alarm wheel: when setting the alarm clock, you can use your finger to turn the setting time on the clock wheel, instead of manually inputting the time (of course, it can also be manually input).

Now, instead of displaying the latest power consumption icon on the interface, it displays the last charging time in text, so that you can see at a glance. < / P > < p > in the end, this is not a new feature. There are new clues to the spatial audio function of airports pro. < / P > < p > at the press conference, the new function of airpods pro to simulate home theater has not been launched yet.
