Sony Xperia Secret Menu for Service Test and Hard Reset

In Xperia series phones of Sony, there is a secret menu which has options for Service test and Hard reset of the phone. This menu is available almost all Xperia phones including Xperia Z, Xperia J, Xperia P, Xperia U, Xperia ION, Xperia S,Xperia E, Xperia L, Xperia tipo, Xperia arc, Xperia zola The menu can be made available by dialing a secret code in the dial-pad of the phone.

Dial pad of Sony Xperia P

The code is *#*#7378423#*#*. When you dial this code in the dialpad, the secret menu will appear which contains options:

1. Service Info
2. Service Settings
3. Service Tests
4. Customisation Settings

In the option Service Info, you can find model information, software information, SIM lock etc.

If you select Service tests, you will get a menu with options to test or diagnose the touchscreen, LCD, camera (front and back), GPS, vibration, All Sensors (accelerometer, proximity sensor, magnetic sensor), speakers, earphone s etc. This option will help you a lot if you are planning to buy a second hand Sony Xperia mobile. Similar diagnostic menu is available in Samsung Galaxy phones also. This secret menu provides all necessary options to carry out any check up. We will come to that later in another post.

If you select Customization settings, you can find Reset Customization, option in the upcoming menu. This option is used to hard reset Sony Xperia phones. I will write another post on hard resetting Xperia phone using  this option.
