OnePlus secret codes
Most phones come with a hidden code that can give you access to new features and extra information about your phone, and OnePlus is no different. If you are using a OnePlus phone, here are some popular codes you can use to learn more about your device and also get some handy features.
Open the Phone app and type the code on the keypad. Most open on their own as soon as you finish typing; a few need the call button. Codes vary by model and OxygenOS version, so if one does nothing, your phone doesn't support it.
