Hey guys, i have found the solution/fix for the game launcher not working on some galaxy devices..
This is my previous community's post, for some idea abt wht i am talking here:
In summary the issue was that the game launcher overlay was not appearing on games and i was not able to use game launcher features.
But i have found a fix/solution to this problem i.e, you need to open "GAME BOOSTER" settings page and there you need to enable the following things:
1) Allow Notifications
2) In Permission: allow microphone, storage and other options are ur choice
3) In advance settings, enable "APPEAR ON TOP' (MOST IMP)
4) And allow change system settings
NOTE: This settings will fix the game launcher issue for those people who could not use game launcher as the overlay was not present on games...
These are some screenshots to the settings i mentioned above: (change the dotted one's)
