Ever since Avast was installed on my Nexus 4, the GPS keeps turning off. If I need to use an app that uses GPS (i.e. Google Maps, Waze, etc.) I have to manually turn the GPS on since it is disabled continuously. Could there be an option in Avast that turns the GPS off? Or maybe after reporting the location it turns the GPS off? I have it set to report location every hour, when I go to my.avast.com, the location has been reported every hour by GPS. Help! :-)
