Advanced/hidden menus – Android system

There are a lot of menus that display to the user some advanced characteristics and variables that are not shown to the normal user in Android Systems.

These menus are used to change or consult some specific features that can be interesting to the advanced users of the system.

In this thread I will show you some of these hidden menus and talk about the advantatges and drawbacks of them.

Not all of them work in all Android operating system versions but the most interesting ones, usually works in most of Android versions.

I have 2 different devices: 1 Sony Ericsson Xperia neo V (which we are going to name it Haida, like in Cyanogenmod ROMs) with the Android system version 4.0.4 Ice Cream Sandwich and 1 Samsung Galaxy S I9000 (which we are going to name it galaxysmtd, like in Cyanogenmod ROMs) with Android system version 2.3.6.

The Android version can be consulted in Settings menu –> About phone –> Android Version.

So I will comment if the Hidden menus are able to use in each device.

So let’s talk about them:

*#*#197328640#*#*

It enters to the Service Mode. It only works with the galaxysmtd and is a very complex menu with 6 parts which are: Debug Screen, Version Info., UMTS RF NV, GSM RF NV, Audio and Common. You have to use the Menu button to go back through all the menus. Here can be consulted variables like the LAC and CellID inside the submenu: Debug Screen –> Basic Information.
Is one of the most completed hidden menus.

*#0011#

This is the submenu commented before but to enter directly. It only works in the galaxysmtd device too.

*#*#4636#*#*

This menu is able for the Haida and for the galaxysmtd. There are 4 submenus: Phone information, battery information, Usage statistics and Wifi information. Inside the Phone Information menu you can change the network option for the phone, and here you can force the phone to use only GSM network or WCDMA (3G) network, etc. There are other options like Wifi configuration in the other submenus.

Here is a youtube video that shows this specific menu: http://www.youtube.com/watch?v=7pjo5sOhn7U

*#06#

This menu shows the IMEI number for Haida phones.

*#*#7780#*#*

This code can be used for a factory data reset. It’ll remove following things:

• Google account settings stored in your phone, System and application data and settings and finally Downloaded applications.

It’ll NOT remove:

• Current system software and bundled applications and  SD card files (e.g. photos, music files, etc.)

Once you give this code, you get a prompt screen asking you to click on “Reset phone” button. So you get a chance to cancel your operation. It doesn’t work for Haida only for galaxysmtd.

*2767*3855#

Do NOT enter this code without reading the paragraph below!!!

Think before you give this code. 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.

Once you give this code, there is no way to cancel the operation unless you remove the battery from the phone. So think twice before giving this code.

You can use this command to reset the original Stock ROM that you have with the Samsung without any update. This can be useful in case you have installed an update that doesn’t work properly.

*#*#34971539#*#*

This code is used to get information about phone camera. It shows following 6 menus:

• Phone/CAM Firmware(FW) Ver Check

• Phone to CAM FW Write

• ISP Ver Check

• FW Write Count

• CAM FW Cal Check

• CAM to Phone FW Dump

I don’t know exactly what the menus do, but all the menus that show the word check can’t be dangerous for the system for sure. It only works for galaxysmtd.

*#*#7594#*#*

This one is my favorite one. This code can be used to change the “End Call / Power” button action in your phone. By default, if you 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. It only works for galaxysmtd.

Other types of codes: WLAN, GPS and Bluetooth Test Codes:

*#*#232339#*#* OR *#*#526#*#* OR *#*#528#*#* –> WLAN test (Use “Menu” button to start various tests).

*#*#232338#*#* –> Shows WiFi MAC address.

*#*#1472365#*#* –> GPS test.

*#*#1575#*#* –> Another GPS test.

*#*#232331#*#* –> Bluetooth test.

*#*#232337#*# –> Shows Bluetooth device address.

*#*#8255#*#*

This code can be used to launch GTalk Service Monitor.

Codes to get Firmware version information:
*#*#4986*2650468#*#* –> PDA, Phone, H/W, RFCallDate.

*#*#1234#*#* –> PDA and Phone.

*#*#1111#*#* –> FTA SW Version.

*#*#2222#*#* –> FTA HW Version.

*#*#44336#*#* –> PDA, Phone, CSC, Build Time, Changelist number.

Codes to launch various Factory Tests:

*#*#0283#*#* –> Packet Loopback.

*#*#0*#*#* –> LCD test.

*#*#0673#*#* OR *#*#0289#*#* –> Melody test.

*#*#0842#*#* –> Device test (Vibration test and BackLight test).

*#*#2663#*#* –> Touch screen version.

*#*#2664#*#* –> Touch screen test.

*#*#0588#*#* –> Proximity sensor test.

*#*#3264#*#* –> RAM version.

NOTE: All above codes have been checked on Google Android phone Samsung Galaxy I7500 only but they should also work in other Google Android phones. But in the newer versions of Android, it’s possible that they don’t work.

All of these codes works for Samsung devices because are extracted from the link below that tells all the hidden menus for a Samsung device.
