Hey I still faced issue with this app. There was only a 70-30 chance of a GPS fix.
However I found something which really works outdoors:
1. Switch on GPS from notification bar and in settings.
2. Open Gravity box -> Click "Engineering mode".
3. Look for Location Based Services.
4. Select GPS at the top.
5. There's a greyed out button "GPS off". Click that button and select "Hot".
This gets a location fix within 30 seconds for me...
Hope it works for you brother..
