This series of phones from Samsung has a hidden menu that users can access– all they need is to dial a set of numbers and symbols. The menu is usually for people running diagnostics on a Galaxy phone. It contains tools for determining whether a component in your phone is experiencing problems, including the display, S-Pen, speaker, camera, vibration motor, and more. If you’d like to see if your Samsung phone has one, it’s important to note that the menu is available on devices that have the One UI. It may also appear on older Galaxy phones running TouchWiz.
