On way back from singing I cycle all around Fernleigh and Sandyford Hall.
Phone memory error just when finished.
When I opened the .gpx file I see everything it had on the latter part of journey is gone! :(
arg.

clearing off photos, videos, sound clips, .gpx files from phone ...

bluetooth also seems a bit flaky
