I love my shields, I have both the tube and the pro in different rooms. I like the Jellyfin AndroidTV app more than Kodi. I have side loaded a different launcher to avoid the ads.
I would love to try and replace it, but it needs to be able to handle 4K UHD rips with hdr and the original sound tracks in ATMOS or whatever.
I was thinking the same thing. The not wanting to know more is a really big red flag for me.
