My good old Sony Xperia P was always had the problem of tracking the GPS position. It’s taking ages to set the location and for this reason my attempts to record the jogging and cycling were ruined most of the times. Recently I’ve found GPS Test, a free app for android which is a very handy application showing the available satellites and SNR.

If this app kept open for nearly one minute, it tracks the GPS position and then I can open up any other app which needs GPS. Hope this would helpful for you as well 🙂
