My (recently fixed) phone locks itself and asks for my code to unlock after 15mins.
The "lock" application in settings->personal only allows me to select upto 15 mins. This is a tad annoying when TomTom is running.
The "prompt if device is unused for" tick box is ticked and greyed out and won't let me untick it!
Can anyone help?
