Anti-theft locator on GPS?

Hello there, I’d like to know how to make the locator on the anti-theft avast program to use GPS to locate the phone when I ask for it.

Right now, it only uses Wi-Fi sources for that, and usually the result is many blocks off from the real location, while I’ve used the phone’s GPS and it’s perfectly accurate.

Pretty much that, cheers
