… Installed Graphene OS and deleted my Google account. May not seem like a big deal to some, but it was a project long in the making. Decoupling from cloud services / apps that are dependant on GAPPS is surprisingly difficult. It felt really good to delete my account in the end.
Not OP, but for me the most difficult would be google maps. our family travels a lot on the weekends, and I become extremely dependent on maps.
