Oppo mobile phone GB code

If you are using the dial of an OPPO mobile phone (ColorOS system), entering a string starting with * # is a shortcut to open a function. For example, enter *#06# or *#66# to check the serial number of the mobile phone; *#899# can enter the engineering mode; *#800# can enter the feedback toolbox.

Tips:

If you don't know the meaning and purpose of the code, I suggest you don't operate it at will to avoid the abnormal function of the mobile phone or SIM card!
