The Galaxy app booster used to be inbuilt feature in the Galaxy devices running with Android 7. Later in the Android 9 update it disappeared from the device and was shifted to Good lock module and recently into Good gaurdian modules.
As you can see in the image it boosts performance upto 15% and i shared the results to prove you this works as it claims to be. I suggest my fellow Samsung members to install it either from fine lock app from the Google play store or your trusted android apk websites.
