Is there any way to repurpose an old android phone into an android TV? Sometimes like Linage OS but TV focused. Even older Android phones can be considerably more powerful than any current streaming box. Add on privacy and you've got the perfect solution. It also would save on e-waste.
Let's say I got myself one of those arm-based single board computers that can run android. Is there not a way to install Android TV instead of "regular" android? i assume you're saying it's not because it requires GMS cert or something.
No no no. You can replace whole OS sometimes, some phones can also do it but in much more hacky way than SBCs. But what I mean is that you cannot replace the interface.
Almost all highly corporate operating systems have their interfaces "welded" in place.
