Here I am, a new member, with a few observations about my new 66st.
I knew about its problems before buying, so I shouldn't be surprised, but... it's just not a good, reliable instrument at this point. Over two years of development and it still behaves like a pre-production test unit. I have to admit that I try to use it a lot to get familiar with its functions, maybe that's why I encounter the issues.
It came with firmware 4.20, I updated it to 7.20 and did a hard reset.
Every day I encounter a freeze or crash or both. One, two or more. What's bad, is that there's no pattern to it, I can't reproduce it. It happens while changing settings or taking a screenshot or deleting an activity (damn, I hate those - give me my simple tracks back!) etc. After all that time they still can't make it work. I never had such issues during years of using my 62stc.
At this point it's a piece of equipment I have to worry about, instead of trusting it. Maybe it's good enough for "Activities" like park running or weekend geocaching, but nothing more.
Here is a log of the latest crash. Yes, I have more of those. Not all though, I stopped paying attention to them at some point.
