Wearing my FitBIt Charge 5 tracker in the shower without activating its Water Lock feature occasionally produces odd results, but the most recent mishap ventured deep into the peculiar:
Its complete lack of buttons makes the thing completely waterproof, but also means it cannot continue when the touch / swipe interface gets horribly confused.
The recovery process requires snapping it onto its USB charging cable, then pressing the nearly invisible button embedded in the USB connector shell three times, with one second between each press: click hippopotamus click hippopotamus click.
Then it restarts / reboots and eventually all is well again.
Perhaps I can now recall the magic incantation without digging through the online help again, because I am certainly not going to suddenly remember to do the Water Lock dance before showering.
