Uses for an old phone include turning it into a remote control, using it as a security camera and giving it to your child. Use the phone as a dedicated remote for home entertainment components by installing an appropriate software application. Many phones have these applications already in place.
Mount an old smartphone or tablet on a window or in a baby's room to use as a Web-connected surveillance camera. You can download a software application that lets you observe the baby's activity from any computer device. Turn the phone into an educational gadget for children by setting up relevant parental controls and installing learning and entertainment applications.
