I\'m developing with the Open Mobile API but so far haven\'t found a list of devices that support the API by default (by default being using the OEM ROM).
I realise
While @Michael Roland response still stands, it's also worth noting that since Android 9 Pie, Open Mobile API is part of the Android.
So for API level 28 and higher, every phone has OMAPI by default and there is no need for explicit check.
