Extra Physical Keyboard Layouts for Android

App overview and purpose

Extra Physical Keyboard Layouts extends Android’s set of physical keyboard configurations. When you connect a keyboard via OTG or Bluetooth, this small utility adds numerous additional layout options to the system settings. It does not create a launcher icon; instead it injects extra layout choices that appear in your device’s language and input settings only while a physical keyboard is present.

Where to find the new layouts

These layouts show up inside Settings → System → Languages & input → Physical keyboard (names may vary slightly by Android version). Note that many of the added options remain hidden unless a physical keyboard is actively connected.

Layouts I checked

• Bulgarian (Phonetic Traditional)
• Armenian (Phonetic)
• Albanian

All three performed correctly during my tests.

Recommended free alternative

If you specifically need Khmer support, consider the free Khmer physical keyboard option commonly suggested by users. It’s a lightweight solution that focuses on Khmer input for external keyboards.

Install and usage notes

• The app is straightforward to install and requires minimal storage.
• After installation, connect your physical keyboard and open your device’s language/input settings to select one of the newly available layouts.
• If a layout doesn’t appear, try reconnecting the keyboard or restarting the device.

Source and final thoughts

The developer maintains a complete list of supported layouts on their GitHub repository. Overall, this app is a convenient choice for anyone who needs additional physical-keyboard layouts on Android: easy to install, unobtrusive, and effective — a solid recommendation for users seeking more layout options.
