Charity is wondering why she can't use GPS in Google Maps. She's on Android. Leo says to make sure your GPS is enabled. You also want to be sure your data is turned on. Leo also recommends using Google's other maps app ... WAZE. It's very popular and if that works, then you know that your GPS and Data is working and the maps app has corrupted. Easy to fix. Uninstall, then reinstall. The chatroom says that there is a legitimate blue dot issue that is related to a weak location. If there's also an error that says "cannot update maps," then that means you're not getting data.
