Other people have reported when playing back tracks from SD that have been taken using a built in tablet GPS, that their altitude drops to zero at seemingly random times during the flight. This can be seen on the elevation display at the bottom. Do a review of the flight to see if this is/was the case. I can only think that the built in GPS on tablets is losing the altitude somehow, maybe through a drop out of number of visible satellites. I don't seem to get it, but I have a canopy aeroplane. I also these days generally use the WAAS/EGNOS enabled GPS on my PilotAware as my GPS source.
