hi
i am looking for a keypad lock with code protection as the one you can find in every decent nokia phone, my old 6310i has it, so why so advanced smartphone like my n73 is lackin in that feature??
i have found some applications like automatic keyguard but the only way to protect my phone now is actually lock the entire phone which make it difficult when i have to quickly answer the phone:(
automatic keyguard would be fantastic, let m know if u see something anywhere
cheers

There's a built-in feature that locks the phone on a timer and requires you to enter the security/lock code to unlock it:

menu > Tools > Settings > Security > Phone and SIM > Autolock period

Is that the feature you're after?

If you want to lock the keypad automatically without a code needed to unlock it, then you need an additional app such as this:
