Thank you for reaching out to us here on the forums! From what I have researched the Samsung Galaxy Note 2 (SGN2) is still considered an Android phone and not a full on Android tablet. This meaning the screen is considered too small to display the full remote. Since the SGN2 uses SlingPlayer for Android Phones the remote functions are carried out by performing the following steps:
Connect to your Slingbox.
While streaming tap the screen.
In the top right corner of the screen is a little icon that looks like a remote, tap the icon.
On the top of the screen there will be a few different menus that the remote buttons will be sorted under.
The following link will show you everything you can do with the SlingPlayer for Android Phones controls.
