Here I plan (with your help) to create a difinitive list of all apps that will work.
I have already noticed that some apps allow themselves to be splitscreened even when they do not appear in that list e.g. official twitter app.
Some apps you will find when you press the edit button, you can then drag them to the main list, or remove ones you do not use.
- Video Player
Third Party Apps
- Official Twitter app
- Polaris (Viewer)
Note: you will need to be using Samsung stock keyboard to benefit from typing when on multi-screen mode, otherwise your keyboard will cover the entire bottom screen.
