How to access Xiaomi Hardware test mode
The easiest way to access Xiaomi test mode is through a code. It's one of those Android codes that let you do things that don't appear in the usual menus.
The code you will have to enter to access this mode is the *#*#64663#*#*. You will simply have to write it on the dial, as if you were dialing a phone number, and the menu will appear on your screen.
Another way to access this mode is to enter the Settings menu, up to the section where the Kernel version appears. If you click on it 5 times, the same menu will appear as when entering the code that we have indicated previously.
