I used to be able to locate my teenage daughter Samsung Galaxy 4s phone using the Android Device Manager. Even with the GPS and WiFi turned off, it gave me an approximate location within meters. For the past 2 days however I haven’t been able to locate unless the GPS was turned on. Is there a way that I can trace it again like it did before with the GPS off? When the GPS is on, it wastes the battery faster, plus she is a minor and I just want to get an idea of where she is.
