I copy videos to USB and use nova player on my Android TV. I don’t have to deal with wifi issues and nova supports Dolby vision as well.

I’m currently using 5iii and xz1 compact. I really like the old school design, the inclusion of SD cart slot and headphone jack, and it’s easy to unlock. However, the update policy is bad (2 yr OS + 1yr security) especially when you factor in the price, and the availability is limited to select markets only.
