Not sure if the following will work, as I don't have access to a Samsung Tab, but you could try these steps to attempt install of archived versions of Flash Player that may work for you:
- Make sure your Android device is connected to the Internet.
- Open the Settings menu.
- Select Security (or Applications, on older Android OSs).
- Place a check mark next to the "Unknown sources" check box.
- Tap OK to confirm your selection.
- Close Settings.
- Launch the browser.
- Goto
http://download.macromedia.com/pub/flashplayer/installers/archive/android/11.1.115.37/install_flash_player_ics.apk
(or you can also navigate directly to
http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions. html for other versions if the one above fails)
- Tap the link to download the Flash Player installer. Download begins automatically.
- When download completes, close the browser.
- Open Notifications.
- Tap "install_flash_player_ics.apk"
- When prompted, tap Install.
- When installation is finished, tap Done.
