You shouldn't have bought that Samsung Smart TV .
You should have bought a dumb TV with decent speakers, a simple remote, and simple HDMI switch box so every user can effortlessly switch inputs . Pair it with an Apple TV and, if you insist , something to stream Amazon video . If you want to record over-the-air TV please report to the local police station .
Alas, you did buy the spyware-by-design  Smart TV. You gaze in horror at the crapware infested screen, remembering pre-iPhone mobile and HP winboxes. Set aside an hour or so, because you have cleanup to do.
Short of hacking the TV your cleanup options are limited to:
- Delete: Only a few of the apps can be deleted. I assume they didn't pay enough to Samsung.
- Move: You can create a folder to move some app icons too. Moves are slow.
- Lock: Almost everything can be 'locked', even things that can't be moved. You can't lock the bundled IE browser however.
- IE Browser only: If you have the patience, you can find a 'restrict' option in the browser settings. Set a passcode and enable nothing.
- Use the Tools button (on remote) to create a folder
- Select items on screen with remote, click Tools, and see your options (Delete, Move, Lock). Delete when you can, Move when you can, Lock all you can't Delete.
 I've had four hours of experience with post-1994 TV. Isn't amateurism wonderful?
 As of today neither Google nor Apple set top boxes will stream Amazon video. Of the options listed here the Roku has a good reputation. The XBOX 360 is abysmal, the original Wii did a good job. I assume Amazon wants to do their own hardware solution. Apple TV does Netflix well. For now we've installed Samsung's Amazon streaming app -- it's slow to start but has worked for a couple of days.
 Few now remember the short time when it was easy and inexpensive to record over-the-air (OTA) TV; VCRs dropped their advanced scheduling abilities in the early 90s. The Tivo era died at the hand of Cable and content owners, now there's a crowdfunded effort for OTA DVR with minimal results. For a brief time Samsung SmartTV supported recording to USB stick or drive, but this interfered with their revenue model and has been quietly dropped.
 Amazon Prime streamed video library is a very mixed bag. Movie selections are abysmal. Television is variable, but they do offer BBC and thus Dr Who. Apple TV has PBS - with some Amazon carve out exceptions. The media landscape today makes the Netflix DVD era seem a golden dream.
 During my cleanup process I ran into at least 4 EULAs; I assume they all grant Samsung the right to monitor everything we do.
 Samsung copies Apple extensively, but they need to copy more.
 Samsung's comparable dumb TV is more expensive than their Smart TV. I assume that's partly better components, but it's possible that the Smart TV cost is subsidized by the bundled video options.

- New LED TV: Family photos look ghastly. Apple T... on App.net Apple TV shares blame here, but, of course, modern TVs are nowhere near as capable as modern computer displays.
