Extra Physical Keyboard Layouts is an Android application that adds several new choices to the list of keyboard layouts when a physical keyboard is connected via OTG or Bluetooth. This app doesn't create an icon of its own, but simply includes some new layout options for physical keyboards. These options can be found under System > Language and Input, and may not be accessible unless a physical keyboard is connected.

This app is a great solution for those who have trouble finding the right layout for their physical keyboard. It is also a great tool for those who want to expand their keyboard options. The app is easy to use and install, and it doesn't take up much storage space.

I tested several layouts, including Albanian, Armenian Phonetic, and Bulgarian (Phonetic Traditional), and they all worked perfectly. The full list of layouts is available on the developer's GitHub page.

Overall, Extra Physical Keyboard Layouts is a useful app for those who need more keyboard layout options for their physical keyboard. It is easy to use and install, and it works perfectly. I would recommend it to anyone who needs more keyboard layout options.
