Mac address is the identity of one's devices connecting to the +Internet through WiFi or Data plan .In android there are ways to find your own Mac address . To know , you may connect to a +WiFi first and use any of the following methods:

 

Go to Settings –> About Phone –> Status.

 

Here, towards the end you will find Wi-Fi MAC Address. Or you may..

 

Go to Settings –> Wireless & Networks –> Wi-Fi Settings.

 

Here, press menu to get the advanced options. In the advanced options screen, you will see MAC Address

Type the following code *#*#232338#*#* to see the WiFi +Mac address. -- This may work only on +Samsung phones.

 

But additional also its just for our own Mac address right?, What about if we want to know the Mac address of other devices like our neighbors Mac address through the android phone we have ?

 

In this scenario, I'm using the +App called " inSSIDer", you can download it free in play store. In this app you will able to see the Mac address of other devices in your phones and signal strength of the connection.
