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.
