Of course, given that this is only the first Q Beta, this could be a bug and not a new attribute of Q. Here's hoping that Google adds the percentage back above the quick settings for those of us who don't have the status bar percentage turned on.
Android Q brings "a number of additional privacy and security features", Google said in a blog post, as well as new camera capabilities, faster app startup, enhancements for foldable devices, and more.
The continued support for the original Pixel and Pixel XL comes as a bit of a surprise, as these devices are already past their promised support window for new features (which at the time was two years from release). 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 from learning your location data when not. Android Q allows you to fine-tune control over location sharing; when an app asks for your location data, you can select "allow only while the app is in use" or "allow all the time".
This is pretty neat and resembles what you can simulate with an app like Focos, which lets you change the shape of the bokeh from a circle to, say, a star, or triangle, or heart. Since Android Nougat, the finalized version of the OS has been published sometime in August with Android Pie having been pushed out the earliest. Furthermore, it will also be used in instances of 3D images and support for AR photography.
"Sharing Shortcuts" in Android Q also makes it easier to share content like a photo withs someone in another app. There are also system images and OTA files available for sideloading. This has been a problem because advertisers would use hardware IDs like your phones IMEI or MAC address to target ads. For example, Google Chrome's display panel might have connectivity settings like Airplane Mode, Wi-Fi and data.
The third option is to set up an Android Emulator to run the beta.
Android Q offers high-performance and low-latency modes for wireless connections.
Android Q provides more support for passive authentication like face ID.
