Android Q (version 10 of the Android OS) was presented and includes the following key features: 1. A system-wide dark mode that can be enabled in display settings and turns the main interface, settings, and files dark gray. 2. Enhanced permissions that show allowed and denied permissions in a cleaner list for each app. 3. Built-in screen recording to record activities on the device like gaming, tutorials, and video chats. 4. An overhauled package installer app that displays in a smaller dialog instead of fullscreen for new app installations.
