Gamming Booster

Game Booster gives you the power to limit what notifications you receive while you're playing a game. You can also disable features like Bixby and the edge panel to help keep your gaming uninterrupted. Game Booster makes your games better by optimising the battery, memory and temperature of your device.

Do mobile game boosters actually work? ... No I don't think you need a “game booster” of any kind. They advertise that they can free up RAM and they do it by closing background applications. But the fact is that the booster application itself keeps running and doesn't shut down once its task is complete.
