If you have a Samsung® Galaxy™, you don't have Linux, unless you had someone flash the motherboard and then manualy install it. Even then, the latest version for Linux is 11.2, which is outdated.
Samsung® sells Galaxy™ tablets with Android™ OS and Android™ is no longer compatible with Flash™ Player. It hasn't been since June 2012.
Android™ (Google™) recommends using either Dolphin or Puffin as your browser if you need to view content that requires Flash™ Player.
You can download them from the GooglePlay™ Store.
