If you own an Oppo phone running ColorOS, you may have heard about hidden dialer shortcuts that reveal device information or open engineering menus. Oppo secret codes are short strings of numbers and symbols you type into the Phone app’s keypad. The moment you finish typing a valid code, the system intercepts it and runs a command instead of placing a call. These are standard Android MMI (Man-Machine Interface) and USSD sequences, not magic passwords, and most of them work the same way across many Android brands.
It is important to be realistic about what these Oppo secret codes can do. On modern ColorOS versions, Oppo and Google have locked down or removed several legacy test menus, so a code that worked on an older Android phone may simply do nothing on a newer one. The codes below are the widely documented, standard Android sequences. We have deliberately avoided listing unverified brand-exclusive engineering codes, because entering an unknown code can change radio settings, factory data, or calibration values you cannot easily restore.
Standard Android secret codes that work on Oppo
To use any of these, open the Phone app, tap the keypad, and type the full code exactly as shown including the asterisks and hash symbols. If the code is supported, the action triggers automatically. If nothing happens, that menu has been disabled on your ColorOS build.
| Code | What it does |
|---|---|
| *#06# | Displays your IMEI number (and serial on some models). Useful for warranty checks and reporting a lost phone. |
| *#07# | Shows regulatory and SAR (radiation) certification information on supported models. |
| *#*#4636#*#* | Opens the Android testing menu with phone, battery, and usage statistics on devices that still expose it. |
| *#*#225#*#* | Shows calendar storage and event count information where supported. |
| *#*#232338#*#* | Displays the Wi-Fi MAC address on supported builds. |
| *#*#1234#*#* | Shows firmware and build version information on some devices. |
| *2767*3855# | Caution: on devices that accept it, this triggers a full factory reset and wipes all data without a confirmation prompt. |
| *#*#7780#*#* | Caution: on devices that accept it, this performs a factory data reset of apps and settings. Back up first. |
The two codes marked with Caution can erase your phone instantly. Treat them like a hard reset, not a quick lookup. Note that ColorOS often ignores these older wipe codes entirely, but you should never type them to “test” what happens.
Safety first before you experiment
The single most important step before trying any code that might reset your device is to make a complete backup. If a code wipes your storage, your photos, messages, and app data are gone unless you saved them somewhere safe. Follow our guide to back up and restore Android devices so you have a recent copy of everything in the cloud or on a computer.
If your real goal is to clear the phone, do not rely on a dialer code. Use the proper menu under Settings > Additional settings > Back up and reset > Erase all data (factory reset), or follow our step-by-step instructions to hard reset any Android mobile. A controlled reset is safer and gives you confirmation prompts.
Whenever a factory reset is involved, remember Google Factory Reset Protection (FRP) and Oppo’s anti-theft lock. After a reset, the phone will demand the Google account and password that were on it before the wipe. If you do not know those credentials, you can lock yourself out, so confirm them in advance and remove the screen lock before resetting a device you plan to sell or pass on.
If a code or a failed update leaves your Oppo stuck on the boot logo, you usually do not need secret codes at all. Learn how to use Recovery Mode to fix your Android phone to wipe the cache partition or recover from a soft brick.
Frequently asked questions
Why do most Oppo secret codes do nothing on my phone?
Newer ColorOS versions intentionally block legacy engineering and test codes for security and stability reasons. The dialer simply ignores the sequence and clears it. This is normal and does not mean your phone is faulty. Information codes like *#06# almost always still work.
Can a secret code unlock my Oppo or bypass the screen lock?
No. There is no legitimate dialer code that removes a forgotten PIN, pattern, password, or Google FRP lock. Any site claiming a magic unlock code is misleading. The supported route is a factory reset followed by signing in with the original Google account, after which FRP releases the device.
Is it safe to use *#06# to check my IMEI?
Yes. The *#06# code is completely read-only. It only displays your IMEI and, on some models, the serial number. It changes nothing on the device, so you can use it freely to verify your IMEI for warranty, insurance, or network registration.
