Speed "0" could be caused by 2 reasons:
1. Phone had hard time to determine the speed due to weak GPS signal but the data is "good" enough because Lat/Lon was obtained fine. The Lat/Lon are always the most significant readings.
2. The phone failed to acquire GPS locations and fell back to "Network Locations", which has no speed data associated with.
The 40 minute apart data just indicates that one data is missing, maybe due to poor sky view that the phone had difficult time acquiring the position at the moment.
