I carry an inReach Explorer+ with me on my daily dog walks because there's no phone signal in the woods where we go. So as I'm carrying it for emergencies, I also use it to track how far we walk, and add the readings to a spreadsheet. But after a couple of months of daily (sometimes twice or three times daily) recordings, it seems to 'get indigestion', and the line on the map misses details out... if I go A to B to C, the display draws a line between A and C, although the distance recording is accurate.
So when this starts to happen, I backup the inReach to my PC, do a factory reset, and then reload the backup — this cures it. But although the backup reinstalls the main settings (preset messages, contacts etc), it doesn't upload the smaller preferences (like icon placings, track send interval etc. So before the last backup I took photos of the screen layouts, and also noted which settings differed from the defaults.
Now, after a Reset, it only takes a few minutes to get back to where I was. It's a pity that the backup doesn't cover this, though.
