MTK EPO GPS Fixer is a free utility and tool app developed by Matěj Trakal for Android devices. However, it is only compatible with Mediatek chipsets like MT6589/MT6592. The app aims to fix the GPS by downloading the latest EPO files from Mediatek servers and putting them in the system folder, resulting in a faster GPS fix.

To use the app, you need a rooted phone and a Busybox installed. You also need to enable all types in GPS settings and disable the auto-download feature in Location Based Service > EPO. Afterward, you can update the EPO in the app and check the expiration date in Location Based Service > EPO. In case the app does not work, you can reboot your phone.

The app provides a detailed guide on how to use it properly. If you have a wifi connection or mobile data, you can use YGPS > Information and click on AGPS Restart for faster GPS Fix. Overall, MTK EPO GPS Fixer is an essential app for those with Mediatek chipsets and experiencing GPS issues.
