Typing secret Android codes unlocks hidden features that you’ve missed

ANDROID phones have secret codes which can fast-track features.

Most users are completely unaware.

These codes can help improve the device's security, backup media files before a factory reset and disable caller ID.

They are known as Unstructured Supplementary Service Data (USSD) codes, and they are programmed into the phone's SIM card.

They look like a random combination of numbers and symbols.

But they can be used by tech savvy Android owners to do all kinds of things without having to enter Settings.

The most codes work on Android phones but some of them even work on Apple iPhones. 

How to use USSD codes on my Android

First open up the device's dialler, where you make phone calls.

Then, type in the code you want to use.

It's as easy as that.

Some codes will start loading automictically, but others will need you to hit the Call button.
