You can download this app from play store Android Secret codes 
Or manually follow the information below;

––> PHONE INFORMATION:

*#*#4636#*#*
This code can be used to get some
interesting information about your phone and battery. It shows following 4
menus on screen:
*. Phone information
*. Battery information

*. Usage statistics

––> HARD RESET
*2767*3855#

This code is used for factory format. It’ll remove all files and settings
including the internal memory storage. It’ll also reinstall the phone firmware.

This code is used to get
information about phone camera. It shows following 4 menus:

need to take your phone to service center to reinstall camera firmware.

––> End Call/Power Button
*#*#7594#*#*
This one is my favorite one. This
code can be used to change the “End

long press the button, it shows a screen asking you to select any option from
Silent mode, Airplane mode and Power off.
You can change this action using this code. You can enable direct power off on
this button so you don’t need to waste your time in selecting the option.
