I've been using trace (2014 model) for a couple of years with almost no problems.
Yesterday while skiing the unit seemed to be turning off many times.
I wrote "seemed" because the blue flashing leds just stopped flashing but pressing the on button would turn on the unit again in recording mode (no need to go from standby mode to recording mode).
As a result i found 25 sessions to upload at the end of the day instead of the usual 1 or 2 and I'm pretty sure it skipped a few runs.
I'm not sure but the flaw didn't seem to be associated to vibrations or some mechanical stress.
Any idea of what might be the problem?
I'm running version 0.4.12 and hardwareID is B2E1503061133380
Thanks for your help
