Kindly check as well as your baseband sir. If you're on 6.15.00 your gps is grayed po dhel sa baseband. So gps tracking is impossible without wifi. But you can opt naman to lower it. papago works without internet dhel po sa gps function/location po. one more thing, it uses up battery very much. Try to find offmaps2 sa installous. Just download manila and you'll have it offline. Exact image as google maps.
