Our smartphones have become extensions of ourselves, facilitating much of our communication and storing troves of private data. If someone wants to monitor your activity, tapping your phone is a viable method. With the right access and know-how, anyone could intercept your calls, but certain codes can help determine if someone is spying on you.
How to find out if your phone has been hacked? An easy way to discover and fix this is by using Unstructured Supplementary Service Data (USSD), commonly known as quick codes. These quick codes can be used as tricks to access secret information related to your device’s security. Using them is as easy as dialling a few digits and symbols; the phone will distinguish your actions at once and give you the answers.
