I do and did this with all my previous phones. Unfortunately, it comes with so many obstacles nowadays like non-working banking apps, that I’m unsure how the future of custom roms looks like. If I need to buy a new phone, I’ll pick one with good custom rom support and a cheap second one just for the banking stuff.
Netflix will show the already produced second season, but I’m not sure if they will order more seasons. Maybe if it wins an Emmy and view count is really high. Let’s hope so!
