Staying on Graphene for the time being. AFAIK should be able to still install apps whatever way I see fit.

Graphene's team has stated that they are looking into OEM's to potentially work out a solution to make a suitable device to run GOS, since Google is locking things down.

If it really comes to it, (long term), I'll make the jump to a Linux mobile device, whether that's a phone or a custom solution.

Just because corpo's are making things difficult, doesn't mean I'm going to cave. I started this privacy journey 6 years ago and I'm not about to undo it because of greed and inconvenience.
