Using the automatic key lock

If your phone turns itself off when being transported, something in your pocket or bag has probably activated the on/off button. To avoid this you can turn on the automatic key lock function. There's more information about this in your user's guide.
Please note that if you click the on/off button for more than 10 seconds the phone will turn off, even if the key lock feature is activated. This is to ensure that the reset function is always available.
