Code to Check if Android Phone is Hacked

Android OS supports several code combinations which can be used to access special functions. Surprisingly, there are several other Android secret codes you can use to access the special accessibility screen to diagnose if your Android is hacked.

Here is the list of some codes to check if Android is hacked.

1. *#62* Redirection Code

This Redirection Code helps you to check if the calls and messages are being redirected.

It is quite possible that all calls and messages from your phone calls are being redirected to their numbers which is a signal of hacked Android phone.

To confirm this, open your phone app on android and dial *#62*. If you are lucky you will find a simple blank screen, but if you see some random numbers on the redirection screen that means, all the outgoing and incoming calls and messages are being intercepted by someone else.

In short, they can hear and read all calls and messages.

2. *#21#: Diversion Code

The call diversion is quite similar to cal redirection. A call diversion is a method to redirect the incoming calls to some other numbers. Unlike call redirection, call diversion is hard to detect.

Call redirection simply disconnected all the incoming calls to your number and redirect them to some other assigned number, these redirections are broadly used to setup voicemail. But, a hacked Android phone can also be a victim of call diversion.

In order to check if your calls are not diverted to any other number, you need to dial the code *#21# and see if there is any number listed.

Just like the redirection code, this code asks your phone to return a list of information that tells you what numbers are receiving your calls, messages, and data. 

3. *#06# EMI Check

You might be known to this number. A code that is used to check the IMEI number of a smartphone including Android.

However, this number has nothing to do with the hacked phone but in case of legal actions and lodging a complaint you will require this EMII number.

Every smartphone has a unique EMI number that is used to recognize the device. If you feel that your Android is hacked, use this EMI number to take legal actions against the hacker.

Also, check the IoT menu codes to check for hardware if you are concerned.
