A:AnswerPreloaded are Apple apps: AppleTV+, music, photos, fitness, podcasts, store, facetime and arcade. It is very quick and easy to download other apps from the app store.
A:AnswerSort of, the Apple TV has Siri built in and cannot be replaced by Alexa. You can use Alexa skills on a separate Echo device to control the Apple TV.
A:AnswerThe current generation Apple TV does support Dolby Vision. Double check your Apple TV is plugged in to an HDMI port that supports Dolby Vision (some TVs only allow certain ports). Also check that your HDMI cable is capable: Go to Settings > Video and Audio and select Check HDMI Connection.
A:AnswerApple TV doesn’t come with any streaming services out of the box / for free except Apple Tv+. You can download most streaming apps from the App Store like Netflix, DirecTV Stream, Hulu, Max, and YouTube TV.
A:AnswerNo it does not matter. As long as the app is available on the App Store for Apple TV, you can use it on your Apple TV. All you need for Apple TV is an HDMI port on your TV.
A:AnswerI guess it depends on how old your "older Samsung TV" is but if you currently are able to get Apple TV+ on your Samsung TV and use cable, then you will certainly be able to get it using this device. If you have any doubts, get the specifics of your current Samsung TV and give the information to the Best Buy consultant. They will certainly know. I used this device to cut the cord and go to YouTube TV (via Frontier for internet access) where I'm getting all of the same channels, but for $200 per month less! Only question was – why did I wait so long?
