In this post, we'll cover eight secret codes every used Android phone buyer should know.
1. Check the IMEI number

6. Hidden test menu
To access the hidden testing menu, type *#0*# followed by any number between 1 and 7 (e.g., *#0*#3) based on which specific tests you want to run. This can be helpful in checking various aspects of your phone's hardware.
