I just got a galaxy s5, wanted to customize the screens and icons a bit more, read about nova launcher and downloaded. Am very happy with the screens and icons, etc. but ever since I did that I can't use google maps gps. What I try to put in an address to ask for directions it says "turn by turn navigation is only available in these location modes: high accuracy (or) device only" Then you have the option of hitting ignore, which means you still don't get directions, or settings, which takes you to the location section of settings. Location is set to on, but I can't see any place where "high accuracy" is an option and don't remember this ever being an issue with my S3 - which is why I think this is related to the Nova Launcher??? Any ideas as to how to fix it. I'll uninstall the launcher if I have to but wondering if there is an alternative.
