I'm bit stuck too upgrading from F1 too, all new Snapdragon chipsets seem to offer similar performance to 845, but my F1 seems to have started to suffer ghost touch.
I have netflix working all ok on mine. My main issue with the F2 is the size and weight. It's a pretty big bit of kit!
I'm also an F1 user, and like it so much that I'm also considering the F2 - only things I don't like on the F1 is no Netflix, stopped getting notifications for some apps (ie Gmail), the inability to remove or hide muii apps (like contacts) and the fact that it's an ugly phone. I'm also looking at the Nord, but those videos on youtube showing its fragility is off-putting.
Have you tried citra and redream?
