Hi There,
Thanks so much for reaching out and sharing your experience. We understand how important it is for your Surface Duo 2 to work seamlessly with apps like Microsoft SwiftKey, and we're sorry to hear you're running into trouble.
What’s Happening
On Android 12, the Play Store version of SwiftKey shows as incompatible with the Surface Duo 2, and login attempts result in an error.
When sideloading the latest version (as of July 29, 2025, version 9.x), login works—but there are display issues, especially when switching between folded and unfolded modes.
What You Can Try:
Sideloading the APK allows basic functionality and login.
Try these general fixes:
Clear cache and data.
Reinstall the app.
Set SwiftKey as your default keyboard.
Disable other keyboards to avoid conflicts.
Sync Troubleshooting:
If login works but sync doesn’t:
Toggle Backup & Sync off and on.
Sign out and back into your SwiftKey account.
Restart your device.
