Just try a standard /e/ OS ROM with microG (without rooting, without Magisk).
Currently, two /e/ OS ROMs are available:
-
/e/ for herolte dev beta (nougat)
-
/e/ for herolte dev unofficial (pie)
It can’t do more than not work. This has been shown time and again in tests with banking apps that also rely on G°°gle Play services.
