Yesterday with no navigation req'd, instead of my usual Etrex, I thought I'd log a ride just on my phone using the resurrected MyTracks. What could possibly go wrong I thought. mid ride - stopped and took some photos using phone, then looked down and phone was restarting! Don't know if it was a crash or i fumbled buttons to cause it. Anyway fortunately the logging had autosaved somehow. I have definitely had previous Strava crashes (and lost all) when taking pics, and gave up 2/3yrs ago with OsmAnd due to the ease of of messing up navigation display by fumbling something, and inexplicable crashes. I do like the OsmAnd display/functionality, and it may be more stable on Android 7. Etrex for the moment.
