So flash is quickly becoming a thing of the past. You can just about navigate the entire web without the need for flash. HTML5 has taken the place of flash for the most part, but there still are some sites, maybe sites that you use regularly, that require flash. Running flash on the Samsung Galaxy S5 is easier than you would think. Simply follow the instructions below. Download the firefox browser to your Galaxy S5 : https://play.google.com/store/apps/details?id=org.mozilla.firefox Download and Install Flash (you will need to enable unknown sources in settings) : download.macromedia.com/pub/flashplayer/installers/archive/android/18.104.22.168/install_flash_player_ics.apk Some websites will recognize you are on mobile and disable flash. If this happens just request the desktop site and you will be good to go.
