Sporadically, my TV seems to freeze, with small letters “tv info” in gray font on a black screen. If I tap the Home key on the Roku remote, it takes me to the home screen. I use a Roku Streaming Stick+ SKU# 3810R with a Vizio TV. Is my Roku device wearing out?
Going to the Roku home screen when you press the Roku Home button is the expected behavior, right?
I've never seen anything like that popup on my 3810 connected to a Samsung tv. I suspect that popup is from your Vizio. What happens if you press Enter (or OK or whatever it might be called) on your Vizio remote?
