If you’re using an Android device, it’s important to keep track of its MAC address. This is the unique identifier for your device. If you lose or forget this information, your Android device can’t connect to the internet and may start crashing. Here’s how to keep your MAC address:

  1. Open a command prompt and type “ping” to see if your Android device is connected to the internet. If it isn’t, try reconnecting it by typing “ping” again and hitting enter.
  2. If your Android device is connected to the internet, open a file manager and browse to “/data/local/com.android.providers.telephony/profiles/0x7f4c0000/.config/” . This file contains information about your phone’s settings and includes the MAC address of your device.
  3. Copy this information into a text editor or spreadsheet so you can keep track of it easily. You can also save this information as a PDF or EPUB file so you can read it offline or on an airplane!
