My girlfriend recently dropped (and broke) her iPhone X. She then bought a used Galaxy S9. The S9 is a few months older than the iPhone X.

Despite that, the app for our home alarm is not supported on her S9, because for some unknown reason it requires Android 11+, and the S9 only supports up to Android 10.
