A:AnswerYes. You can download apps onto this television. All of the popular apps (and a whole lot more) are available - Netflix, Amazon, Hulu, Disney+, ESPN, Amazon, etc.. ESPN is installed on it as one of the default apps.
A:AnswerAs easy to use as can be had these days. My mom is in her mid-80s. I was happy that I was able to teach her to push the home button to call-up the apps. I couldn't imagine being able to teach her to use multiple remotes although my challenge with this is teaching her that she has to put down the cable remote and use the TV remote to watch Netlix. It's a challenge in progress.
A:AnswerI haven't had that problem, but this can happen on any TV depending on what input device your are using. Does it happen on over the air TV, or Roku?
A:AnswerI've always run into doing any sort of screen casting with my iPhone (or any Apple device). You could work around this (theoretically) if you used adapters to hook your phone up to an HDMI cord. I've only don that with a mac/iPad, thought. There may be a way to do it, but from what I've found you need to have an AppleTV to do it easily.
This article (https://www.guidingtech.com/mirror-iphone-screen-android-tv/) explains that it's possible with a third party app. You could try that. Not sure if it works reliably, though. There's always a risk to using third party apps like this, so I would be cautious.
A:AnswerYou can get some 4k hdmi cables fairly cheap,dont fall for those $50 cables I believe as long as there hdcp 2.1 it's good for hdr 4k,opposed to hdcp 2.0. But if your reciever only puts out 720p or 1080p any hdmi will be fine.
A:AnswerYes. A lot more advanced than what I have on my 8 year old Samsung in the living room. You have access to all major apps including Disney+ and additional apps.
A:AnswerThe unit comes with Wi-Fi and will stream all of the included apps. Buffering will depend on your internet connection. We are at 100 megs and no issues ,great little tv !
