Victor KachiSecret Codes That Unlock Hidden Features on Your Android Phone
Did you know that smartphones are ‘equipped’ with secret codes that can unlock (or lock) a number of different functions which propound a service known as "Unstructured Supplementary Service Data (USSD)" or backdoors. We mostly know this as "quick codes", secret code or "feature codes". This code is an extra UI protocol, which allows people to access hidden features.
If we come to trace the origin of this protocol, it was originally created for GSM phones which can also be found on CDMA devices in some cases.
They are accessed by inputting them into the phone's dialer (it can be found on the phone home screen which is mostly green in color) and usually begin and end with the * or # keys with a sequence of numbers in between. These are available publicly as a back channel that allows users to directly communicate with their service provider.
The most tricky part is that most people don't really need to know how their local cell towers are performing or what their IMEI number is which is not supposed to be because this are part of the hidden features you have to fish out first when you own a phone.
Today, as this topic above is concerned, we will provide you with the list of codes to fish out hidden features on your device. These codes seldom work across different carriers, OS, or phone models (or even on generations of the same model).
On a normal instance, not all these codes might work on all devices but mostly all devices so If you really want to try them out, your best bet may be to Google your phone's make and carrier "USSD" for a well comprehensive list. Though I have tried some of these codes on device like Samsung Galaxy S7 Edge Galaxy S5 and even iPhone, most of these codes work perfectly well
Now, we are moving, check out these list below for codes that mostly worked on all devices.
What is Call Forwarding? This is a feature of some telephone switching systems which redirects a telephone call to another destination, which may be, for example, a mobile telephone, voicemail box or another telephone number where the desired call party is available.
To carry out this operation, Dial *#67#. Once you enter this code above, it allows you to check which number your phone is currently forwarding calls to when you're busy or reject a call. This carries a voicemail but you can change it to forward to a different number or even third-party answering service.
If you want to do this on an iPhone, you can change this number by doing the following;
>>Go to Settings >>Click Phone >> Tap on Call Forwarding.
If you want to do this on Android also
>>Tap the Dailer app
>>Click on hamburger icon
>>Go to Settings >>Call Settings >>Select the Sim>> Call forwarding. From there you can set a call forwarding feature or disable it if activated.
To do this... dial *#61#
This code prompted a pop-up on Galaxy device that let you know how long until a call is forwarded to the message center.
On the iPhone, you can dial on *#67#.

>>Press the green call button to access "Field Mode," which can give you access to info about local networks and cell towers.
