The official Netflix apk for Android devices. This is an Android (Vanilla) version, not just for Android TV. If you want to use it on an Android TV device or an Android TV Box you will need to use a mouse or an air mouse remote control. Note that sideloaded apps as this Netflix application for Android will not appear on your default launcher.
This solution for some devices like the Cosmote TV OTT that do not support Widevine L1 DRM will only play video on standard definition 480p, not HD or 4K. The alternative is to use the Netflix KODI addon inside KODI media player.
