Using the codes is very much at users’ own risk — But, if you dare, they can provide access to hidden options within the phone.
All of the codes are used by dialling them into the phone app and then pressing send. Most should bring up a menu as soon as you do that — though the extreme factory reset option will just start going straight away.
If you’ve ever had to take your phone in for service or had a technician help you over the phone you’re familiar with the odd series of # symbols and numbers they’ll have you enter to help diagnose your situation.
Note that many of these may be manufacturer-specific, so they might not work with all devices, and, as always, proceed carefully.
A picture they say speaks louder than a thousand words. Here are some of the most useful ones. Users discretion is adviced. Please use this for developmental and educational purposes only. Always have it in mind that merely by dialling one of the codes elow, you can lose all your phones data. Itis as simple as that.
