Android Q will have a "Live Caption" feature that will bring captions to any video on your device, even your own home videos.
Live Caption will bring captions to your home videos, apps, and web content, and it all happens on your phone, which is pretty significant for privacy.
Typical live captions that haven't been pre-written need to go to a server to be analysed, and the captions are then sent back to your device. Having the captioning made from a device itself without even needing an internet connection means your video's audio isn't sent to some server somewhere.
Live Captions is "OS-wide," Cuthberston said, which means any audio from Android, your apps, and web content can get captions. That's fantastic for Android users who are hard-of-hearing, and it's also great for generally quieter usage when you don't have access to headphones, or it's inappropriate to use a phone's speakers in a public setting.
Smart Reply is coming to Android Q, Google's service that predicts what text you'll type next — and it can even predict actions you'll take.
Smart Reply was previously only available on Google's own Messages app, but Android Q will bring Smart Reply to third-party messaging apps.
Smart Reply will also suggest the most likely action you'll make after reading a message. The example Google gave was receiving an address in a message, and Smart Reply will suggest you open the address in Google Maps. Tapping on the suggested action will open up the app and show you the relevant content.
And my personal favorite upcoming feature: Dark Theme.
Dark Theme will give Android and Google apps a black color theme, which Cuthbertson and Google have previously said will improve the battery life of your phone.
Better battery life is all well and good, but darker color themes are also more comfortable on the eyes.
Cuthbertson didn't specify how far-reaching the dark theme in Android Q will go — as in, whether the dark theme will apply to non-Google apps when you enable Dark Theme mode.
