Why can't I switch languages on the Bluetooth keyboard BKB50 after updating to Android 7.0 Nougat?
You may experience that you cannot switch languages using Ctrl+Space on the Bluetooth® Keyboard BKB50 anymore. This is because the shortcut has been removed in Android™ 7.0 Nougat. However, the keyboard still has multi-language support. To switch languages you can use two different keyboard apps with different languages, and switch between them by tapping the keyboard icon in the bottom right corner of the keyboard.
