I love the idea of Linux mobile but i think it is going to be limited by upstream support from SOC manufacturers. Personally I think we are going to have to keep using android and if it gets bad enough it will be less effort to get an open source fork of android working than reinvent the wheel with Linux mobile. Although I’m not a Linux or android dev so I could be wrong.
That’s a terrible idea
Just as an example chromite uses adblock plus where as Ironfox uses unlock. And sandboxing whilst has it’s benefits for privacy is more of a security feature.
Gecko based browsers have worse sandboxing than chromium based browsers on android. But for privacy I think the best would be Ironfox or vanadium however vanadium only runs on Graphene os. Chromite is probably a good next best option.
This is the way
