This really irks me. Even if not connected to the internet, it still has whatever android bloat OS on it. Ageing android (or any other) are just intolerable even when they haven't completely rotted. It will fail. A family member let us borrow their second smart TV, a Samsung, and it would not function, internet or not. It would crash on turning it on, and even if it didn't crash it took six or seven minutes to get from standby to 'actually displaying HDMI 1' if it didn't crash. A quarter of the time crashed so bad on turning it on that the firmware had to be reflashed. I gave it back. Don't get me started on all the weird android alzheimers bullshit like trying to set the time (so the old fashioned EPG would work) would set the time to literally anything but what was input and did so in a totally random and unpredictable pattern meaning it couldn't just be worked around.
I was grateful to find a totally dumb 4K 48" TV that had the same firmware as the decade (at minimum) old 1080i 23" TV it was replacing. Its image quality would offend TV nerds but I will never ever own a smart TV and they don't really make actually dumb TVs any more. You could not pay me to use a decade old android or tv os device, let alone the considerably younger TV we borrowed. Absolutely not.
