Part 1: What Are Secret Codes?

Secret codes are sequences entered into your phone's dialer (the Phone app) that trigger hidden activities within the Android operating system. Unlike standard USSD codes (like *#100# for your phone number), these codes start with *#*# and end with #*#*.

On the Poco X6 Pro, which runs HyperOS on a MediaTek chipset, the codes are slightly different from Qualcomm-powered devices (like Samsung or older OnePlus phones). The Poco X6 Pro uses MediaTek's engineering architecture, so many codes are MediaTek-specific.
