I have been using Wholphin over the official Jellyfin Android TV client for months now. I have trouble with some Dolby Vision content with the official one. Wholphin is able to play those files fine. Wholphin has an in app updater that makes it really easy to update. No need to touch the Play Store (or even have it enabled lol). I appreciate all the work that goes into Jellyfin and Wholphin allows me to get the most out of my server.
