I use ADBFileManager https://github.com/T0biasCZe/AdbFileManager/ which is much faster than MTP

In my testing, the program copies files at speed of approximately 41.6MiB/s (332Mib/s) over USB 2.0, compared to MTP that copies at around 10Mb/s

You can install addons directly on your android de hice. They do sync across devices, which is nice

I think stremio on the fire tv stick is the best approach: begib with this guide https://www.youtube.com/watch?v=UWHhSzQyX4Q and then https://www.reddit.com/r/StremioAddons/comments/17833ms/stremio_all_you_need_to_know/
