My Sony Smart TV is crap and I will never buy another Sony TV. Yes it runs android. It's slow to respond to input. Sometimes when I'm guessing it needs to page out code it can take 5-30 seconds before u can actually use it. It's crashed in the middle of watching shows and I mean the TV is being used as a dumb tv with input from an external source and suddenly android reboots. It also covers the home screen with ads for shows/games/movies. If possible my next TV will just be a 60inch monitor
I bought a Panasonic 1080P dumb TV a few years ago. Turns on instantly, no apps, no ads, no updates, no tracking. I have no idea what I'll do when it finally dies.
For streaming and playing media from my NAS I use an Nvidia SHIELD TV. It's based on the Tegra X1 so performance is on par with the Nintendo Switch. Really great bit of kit, and of course I can just chuck it out (or repurpose it as an emulator box) if it gets too annoying.
I own a Sony smart TV - it’s awful. Far and away the worst piece of consumer electronics I’ve ever owned. It’s ruined Sony for me as a brand. I always take the opportunity to tell people how much I hate it whenever the opportunity comes up.
