Unfortunately, Tinder doesn't work and that is helpful to get in touch with the ladies. That app is too hell bent on location data which GOS handles more privately.
NFC should work, it is just scheduled to be deactivated after 3 months if not used for security reasons.
I think GOS is very user friendly and has many positive privacy and security enhancements. I would like to see if they can surpass sandboxed Google Play and officially support other repositories and updaters like Accrescent. Also, a standard way of securing traffic beyond encrypted DNS would be good such as a tor client like Orbot.
Looking into the Veilid ecosystem might also be a source for further development ideas.
