Tips and Tricks For Your Device may teach you something new, or remind you of a neat function you've forgotten about!
You like your phone locked - no snoopers allowed! Yet the 4 numeric digits just don't seem enough to guard all your phone's secrets. How can you increase the length of your passcode?
Go to Settings/Passcode Lock and enter your current passcode if you have one. If you want a more elaborate and lengthy passcode, toggle the Simple Passcode bar OFF. You will then be able to enter a new alphanumeric code in its place as a keyboard will appear complete with a textbox for your new entry.
