Symbian Useful Codes

Last week I am said about some Android Secret Codes, Today I like to share some Symbian Useful codes.

What is Symbian?

Symbian is a mobile operating system (OS) and computing platform designed for smartphones and currently maintained by Accenture.
Symbian was originally developed by Symbian Ltd.
The first Symbian phone the touchscreen Ericsson R380 Smartphone was released in 2000 and was the first device to be marketed as a 'smartphone'.
S60 is mainly used by Nokia but has also been used by a few othermanufacturers, including Lenovo , LG Electronics,Panasonic , Samsung,Sendo,and Siemens Mobile.
1st edition of Symbian is S60v1 and last one S60v5 and Nokia Belle.

Symbian Codes

Set of useful codes that are working with handsets featuring the Symbian operating system. Either you have a Nokia, a Sony Ericsson, an LG or any other mobile phone that features the aforementioned OS, these codes will work and will show you the info you need. There are some codes that can temper with your OS or data that you have stored on your handset, that's why it is better to make a backup before using them.
1)*#06#
The most common one, which I think goes as a universal code and will work 99% on all Nokia phones is *# 06 #. Tap it on your keypad and it will display your IMEI (International Mobile Equipment Identity), which might come in handy for those who are looking for various ways to tune up their device.
2).*#0000#
This will show in-depth system info such as: version firmware, release date of firmware, version of hardware and version of phone.

3).*#7730#
You must be carefully used as it can delete all your data stored in the phone's memory. Its called 'Reset Phone' code,*#7370#, does exactly what its name suggests, meaning that it totally resets the phone, wiping everything and completely reformatting it. You'll have to reinstall everything you had before if you didn't make a backup prior to resetting your device. Before doing a Hard reset it's better to have your battery fully charged, as the process cannot be stopped. In case this happens it will surely brick your phone, rendering it useless.
4).*#7780#
The Soft reset code, *#7780#, will simply restore your phone's settings to the original factory ones. This process won't wipe outall the info stored in the phone's memory, only that the settings willbe restored to their original state. Bear in mind that the default lock code after the Soft reset is over will become 12345 again.
5).* 3 Green (Formating Phone)
If you cannot reboot your phone because you forgot your locking code there's another combinationthat is used to hard reset the device (similar to #*7370). You must switch off the handset and then press and hold the Accept calls key (Green key) * key 3 key power button for a couple of seconds.
you can able to see formatting in Phone Display.
6).*#2820#
Which will display the Bluetooth address (if your device features one).
7).*#62209526#,
Which displays the MAC Address ofyour phone (for those with Wi-Fi).
8).*#92702689#,
Which will show the time the device has been in actual use. The latter is called Global Usage Counter and cannot be reset, not even using one of the methods described above, the one that will change all the settings of your phone.
