I have Samsung Galaxy S4. I am trying to get the GPS work on offline maps. I am for instance trying this on MAPS.ME app. If I have WiFi or 3G signal, the location works great. However if I turn on the airplane mode, and the location on, the application cannot find my location. I had the issue with Android 4.4 KitKat and recently upgraded to Android 5 Lollipop and the issue is still there.
I am pretty sure it is not an issue with the app because I also tried on Google Maps with a preloaded map and it is the same. I have also downloaded GPS apps such as GPS Test and GPS Status and they all manage to connect with satellites and find a location, even offline. I think that proves that it is not a hardware issue.
I think I might have unselected a Google option somewhere to block the GPS usage (I am usually very careful not to give Google too much data about me)
Any other ideas on fixing this issue?
