Secret codes FAQ
Why does a code do nothing on my phone?
OEMs remove or rename dialer codes often. Treat this list as a technician reference, not a guarantee for every firmware.
Can these codes unlock FRP or network locks?
No. Service menus are for diagnostics. FRP and carrier unlock usually need authorized tools or a verified technician job.
