As the name suggests, the Brydge 10.2 Keyboard for Apple iPad is only fully compatible with iPadOS. The ‘On Screen’ button only works on iPadOS, while the lock key works for Android and iOS, but not for Windows, Linux, or macOS. The Siri button doesn’t work on macOS and Linux, and it acts as the ‘Home’ button when using Google Chrome on Windows. Also, the media keys don’t work on Linux operating systems.
