Thanks, man, this was what I needed. Running on a Moto G9 Plus!This is a Netflix apk to force HD (1080p) on Widevine L3 devices. So basically any phone with a custom rom, where you can only watch SD netflix. Your device has to support L1 though (the v30 supports it). It's an old version (4.1) so the gui is not the best but it's the only one that works (with newer versions the hack is not possible for technical issues).
The original work is by Jonas-coded here:
I've only added a string of code to make it work on full screen 18:9 for our v30. Since Netflix wasn't 18:9 at the time.
