Just wanted to throw out an FYI about recording game play with the Samsung game launcher. There's a setting that gives you the option to either record game sounds or microphone sounds (i.e. everything you say!). By default the record mic sounds is enabled. So if you don't want your conversations recorded you have to change it to record game sounds. Although it could be used to secretly record a conversation. You have to go into settings from within the game to change that option. By clicking the red floating game launcher tools button then clicking the wheel in the upper right corner.
