There is also an app called “Secret Codes” which will find other codes that are used by applications and not the OS itself. Some apps let you access secret settings with these codes.
These are not “Android” secret codes. These are “Samsung” secret codes. Except one of two none of them will work on any device other than a Samsung phone.
F.A.Q.
Q: So how do you enter these codes?
