grayway2 Thanks. But yeah I did see that, but its weird. Surely there's a way without a google account? It doesn't let you do it with a brand-new google account either without providing personal information to verify your age. Why can't they just provide a list of affected IMEIs (or whatever hardware ID)?
Have anyone (a GrapheneOS developer?) found an IMEI list or unrestricted API URL in a recent update or the battery app?
