One of the nice features with Windows Phone 8 is the Kid's Corner. If you go into the settings and turn this feature on, you can select games, music, videos, and apps that are age appropriate for your children. While in the Kid's Corner, these selections are all your children have access to. It is designed to create a safe environment for your kids to access and protect the more sensitive stuff on your Windows Phones from curiosity.
But there seems to be a slight bug in accessing the Kid's Corner if you use a PIN Number to lock your Windows Phone. When a PIN Number is set, if you swipe right from the lock screen to access the Kid's Corner that PIN number is required to unlock the Kid's Corner.
