Google today revealed some key new features of Android 10 Q. The first is Live Caption, a system-wide feature that uses on-device speech recognition to automatically add captions to any video played on the phone, including video calls. Because it uses new on-device speech recognition, it works quickly, privately, and even offline. A new Focus Mode blocks notifications from a configurable list of "distracting" apps while enabled. A new Dark Mode helps save power on phones with OLED displays. New parental controls built right into the phone's main settings let parents set time limits for specific apps, set a bed time that can be extended with "bonus time" by the parent, approve new app installs, and review screen time by app. New privacy controls offer more granular control over apps using location data. Q also offers better support for foldable phones. The third beta of Android 10 Q will be available soon for 21 devices from 12 different brands.
