it would be a fair bit of extra work from it’s current state to make an “off the shelf” android version of this I think.
I got a “smart” TV, but have never connected it to a network… I made sure I got one with an ethernet port, turned wifi OFF and have never plugged in a network cable. The IP address has been set to something that will never work in the off chance someone ever does accidentally plug it in.
I made sure it is one that can be upgraded with the firmware on a USB stick, it does not need to be online to be upgraded…
It is used as a huge monitor for a Linux multimedia PC, but that’s fine!
as long as you’ve removed all the surveillance capitalism crap that is baked into a lot of off-the-shelf android appliances…
