GPS Guard is a free utility for your Android devices. It has been designed to block out various spyware, malware, or other applications which are trying to spy on your location. It will provide useless fake data to them and protect your real location. You can allow mock locations functionality to work properly.

This utility is designed to work on Android .3+ devices, but you need to enable the developer options in your phone or tablet before it can work properly. You need to enable the developer options by going to Settings-About and pressing 7 times on the Build before you can enable the ALLOW MOCK LOCATIONS option.
