This title may sound somewhat misleading in the light of the Huawei ban that severed all the ties between U.S. partners and the Chinese telecommunications giant. Right off the bat, this article has nothing to do with any secret codes that are used for spying, nor can they turn your smartphone into a James Bond-like device.
Quite the contrary, similar secret codes exist on any iOS and Android device, Huawei, Samsung, One Plus, or Pixel. By design, most of these codes give you additional information about the phone. Though, there are codes for engineering and debugging purposes, so be careful with them to avoid inadvertently messing up the settings.
