All About Privacy and Darkness
Google Android Q focuses on privacy, but its most popular feature will probably be a new dark theme.
Dark Theme
The Android Dark Theme is very, very dark.
New Gestures
Android Q offers three different gesture navigation options. The topmost option replaces all buttons with a thin line that you toss to exit apps and pull to open the app manager and the app drawer.
Privacy Up Front
A new Privacy settings option collects existing privacy options and adds a few new ones, all in one place.
Location and Permissions
An improved Permissions viewer lets you see which apps can access what information. Location, for example, is shown here.
Location, Location, Location
A new permissions option for Location grants an app access to your location data only when the app is in use.
New Options
Google has added privacy options for deleting your Location History information and quick access to these controls, which prevents apps from monitoring your activity. You'll still see ads, however.
Ad Identifier
The Google Ad Identifier is an important number you've probably never heard of. It's an ID that advertisers can use to target you for ads, but you can cycle it manually to make it harder to keep tabs on you. In Android Q, Google is pushing more apps to use the ad ID instead of permanent identifiers like your phone's IMEI number.
Faster, Smoother Sharing
The Android share sheet is faster, and smartly redesigned to be more convenient.
