 Many phones have a portrait mode that blurs the background of a subject in a photo. The depth-mapping data used to create the effect is discarded after the photo is rendered. Dynamic Depth will allow apps to use that depth data to offer specialized blurs and bokeh options. Developers can also use Dynamic Depth data to create 3D images and AR photography. Since Nougat, opening apps has gotten faster as Android learned which parts of an apps code is used frequently. Now with Android Q, Google apps can launch immediately. Developers can use Android Q to process app data earlier and then move it to a security container, so it's ready to launch.

Privacy protections:

You'll have more control over apps and their access to shared files. This is one of the biggest updates to Android. You can also control an app's access to the Photos and Videos. For Downloads, you can decide which Download files an app can access.have more control over location settings and permissions. When prompted to give apps permission to see your location you can choose: never, only when the app is running, or all the time -- even in the background. So if you are using a ride share app you can let it track your location while it's in use, but forbid the app accessing your location data when not.
