In fact you can use your smartphone to change the channel on nearly any TV. In the comments on that post some people talk about how to do it. Basically you need a smartphone with either builtin IR or use a USB-C IR blaster or if your phone has a 3.5mm headphone jack you can also try one of those but I’m not sure if the 3.5mm ones are as commonly supported.
the tv-b-gone is more universal than a universal remote….
my favorite trick is going to one of those bars with 30 tv sets everywhere… although that’s just kind of neutral-evil
