Learn some hacks and codes to enhance your smartphone’s privacy and security. Google’s Android has become so popular that most users operate their smartphones in the USSD code way. The operating system is the most popular globally, powering about 2.7 billion devices. People who’ve used the devices for a long time now use the Unstructured Supplementary Service Data (USSD) interface protocol to unlock hidden actions in their smartphones.
The USSD is an Android interface protocol that lets you use “secret codes” to access hidden features in your device.
Most USSD codes work immediately you input them into the dialer. Ensure that you enter the Android security code correctly and expect an automatic response. Some devices may require you to press Dial to unlock the action.
Below are some common secret codes you can use to operate your smartphone in style.
- *31# (Disable Caller ID)
If you don’t want your contacts to appear on the recipient’s phone, disable the caller ID by using *31#. The same code will reverse the action, so you need to check on the message whether the input has disabled or enabled caller ID.
- *#*#7594#*#* (Instant Shutdown)
This code changes your smartphone’s power button’s behavior to shut down the phone immediately and skip the Power Menu. In most cases, Android devices introduce this menu when you long-press the power button.
Entering the *#*#7594#*#* code will shut down the phone immediately without displaying the Power Menu. The capability comes in handy in compromising situations when you may want to switch off the phone quickly. Note that the smartphone will request a passcode on startup to confirm that you’re the rightful owner.
- *#06# (Device’s IMEI)
IMEI stands for International Mobile Equipment Identity. It’s simply your phone’s ID or fingerprint used by phone manufacturers and carriers to enable tracking of compromised or stolen phones.
So, if you’re buying a brand new or pre-owned smartphone, it’s essential to check whether its IMEI matches with the one shown on the back and the box. Enter *#06# in the dialer to see the serial number of your Android device.
- *2767*3855# (Wipe Your Device)
This code that can help you quickly wipe your device information clean. Inserting the code in the dialer is the simplest way to do a hard reset. The only thing that this code leaves is the firmware. *2767*3855# reinstalls the deleted firmware, ensuring that your device’s software is as good as new.
Please note that this code initiates a hard reset and is recommended only when in an absolute emergency.
- *#0*# (Activate General Test Mode)
If your Android smartphone malfunctions, you can conduct a General Test Mode by entering *#0*#. Once you enter the code in the dialer, the display will show a litany of different features such as LED, RGB testing, Touch testing, Grip sensor testing, Front cam, and Device version. Now you can test features individually for any root-level tampering in your smartphone.
- *#3282*727336*# (Access System and Storage Information)
You no longer have to follow a list of steps to access your device’s crucial data, such as storage and data usage. By running the *#3282*727336*# USSD code, you access accurate information on the available storage and the internal status of your Android device.
- *#*#7780#*#* (Factory Reset)
If you don’t want to run the hard start discussed in the fourth code above, this code provides a better option. Just like the hard reset, the factory reset will delete every application and data in your smartphone.
This is the best option if you don’t want to tamper with the firmware and only want to remove app data, apps, and personal data from the device. The quick and general process initiated by this code addresses any privacy concerns, especially when selling your phone.
- *#*#232338#*#* (MAC Address)
In this case, MAC stands for Media Access Control, an address assigned to every device for identity, especially when connected to a network. If you suspect any tampering with your MAC, you can check this on the device and confirm whether its correct from the network.
- *#*#4986*2650468#*#* (Firmware Info)
This is the code you use to access critical information about your device’s firmware. Once you enter the code, you get the manufacturing date, RF call date, hardware, phone, and firmware information PDA. So, you can check the firmware information using the code whenever you feel that it has been tampered with.
- 10.*#67# (Call Forwarding)
The *#67# code will tell you whether you have call forwarding enabled on your device. It will also show you the number of all your forwarded call. You’ll also know whether calls are being forwarded when you reject a call or when your number is busy.
- 11.*#*#34971539#*#* (Camera Information)
The last code in this list provides comprehensive camera details, including firmware version, maximum zoom, number of cameras, and more. Entering the code will also help you detect any camera firmware tampering, given that smartphone cameras now come with several modules.
