Samsung's Game Launcher 2.0 update brings curated discovery, game tools for regular apps
The tools let you minimize the game screen when you have to make a quick run and do something else on your phone, switch off distracting notifications and lock navigational keys so you don't inadvertently mess with the gameplay, and also lets you record and broadcast gaming sessions.
The new Game Launcher 2.0 update can be downloaded from Galaxy Apps on older phones like the Galaxy S6, S6 edge and S6 edge+, while your newer Samsung handset like the Galaxy S7, S7 edge, S7 active, Galaxy Note5, Galaxy A8, C5, C7 and C9, should have it preinstalled.
