Exactly!
Nothing more, nothing less.
This means, rooted devices with LineageOS can run Netflix 5.x!
(like my Samsung Galaxy S4 Mini running LineageOS with addonsu)
As long as you don’t install addonsu (LineageOS Downloads) you can even download Netflix from PlayStore (I’ve tested).
That’s because without addonsu you don’t have root access (/system/bin/su), which is what the PlayStore is checking for.
But because of this is may be hard to get help from Netflix.
Rooted or uncertified mobile devices […] depending on configuration, may not function properly.
Luckily we know, that Netflix 5.x runs on the Fairphone 2, because it works fine on the Fairphone 2 stock OS (even on the FP Open OS). So it’s not a hardware problem.
And we know, that Netflix 5.x runs on LineageOS.
My current guess is, that this problem is something about:
- a driver being different from the ones in the Fairphone 2 stock OS,
- or a compilation setting being different from the ones used for other LineageOS build like the one for the Samsung Galaxy S4 Mini (serranoltexx).
Unfortunately I do not much about building LineageOS ROMs. So maybe someone can help who knows more about that.
