How to tell when there are updates for TV

[Vallistic]

How do I know if there are updates for my TV? Also, why are my Samsung plus channels changing on their own. Today it’s really bad. It’s switched channels at least four times.

I will check to see if there is an update available.

It will usually pop up if there's an update. Or you can go to the settings and check for Update
