I bought my first "smart" tv last year, made by Sony. When it works, it's a great tv but every now and then an app will temporarily lock up and you have to wait 10-15 seconds for the tv to come back to life. Or other times it locks up entirely and I need to manually power cycle it. It's an Android TV. I do enjoy some of the app integration (hulu, netflix, amazon), but at this point, I'd rather have a stable tv and use a roku instead.
