An "update" to my TV made it so if it's on an input channel with no detected input for 10 seconds it will automatically switch back to the "smart" TV channel. Now if for some reason an input source isn't working correctly and I'm trying to figure out why I have to keep switching back to the correct input channel. Which of course lags for like ten seconds whenever it switches. I'm never buying another "smart" TV.
