Thanks for that, I thought it was just me who had the issue. It appears to be the feature on 1055 was to be blamed. I think I will try it again on 1925. Let's see how it works. I do not want to take chances and wipe the phone again.
The best thing to do is to set a password and then set the picture password. This will make sure that when you reach 5 attempts, it will prompt for the device password. Trying it now on 1925.
