Play Facebook Flash Games, Stream Youtube.com, and Browse Flash Sites on your Samsung Galaxy Tab, Tab 2, & Tab 3 (All Versions)
Adobe Flash stopped support for mobile devices a few years ago, luckily we can still install Flash onto our Samsung Galaxy devices. The tutorial is the same for all the Samsung Galaxy phones and tablets.
First you will need to make the Unknown Sources option is checked. Go to Settings -> Security -> Unknown Sources
On your web browser download the Flash .APK installation file here: http://download.macromedia.com/pub/flashplayer/installers/archive/android/18.104.22.168/install_flash_player_ics.apk (the download is direct from Adobe)
Install the file; this will install Flash to your device. You are done! You will now need to use a Flash supported browser to use Flash. Download Firefox or Dolphin Browser from Google Play as these are the top free Flash supported browser for mobile devices. Note: Google Chrome does not support Flash.
