Samsung One UI Home

If the device maker doesn’t integrate some sort of a launcher or dedicated application in their product, then you’re likely to be using the stock launcher available in Android. Since the official Google Play store is full of launchers that usually work on most devices, it’s quite easy to find a good one.
One the other hand, the TouchWiz Home launcher is a great solution, and it should offer all of the features that a user might require. In this case, it’s the entire package, with the app drawer, comprehensive settings for the home screen, widget support, and so on. It’s the kind of app that you don’t know what it’s called, but you use it every day.
