Do you experience random reboots and/or freezes when doing an activity? If yes, please comment.

It is mind boggling how systemic the reboot during activity is with the Fenix 7 series! I'm not aware of this issue with the 8 series and came from a 6x Pro and never saw it. Is there not some way to replicate the software from one of the other versions to correct the problem in the 7 series? I'm on my 2nd 7x SS and will be calling to try a third one. Really can't understand how this has persisted for so long now.

On my hiking trip today, I had my first crash with 16.22. After 1.5h in, the watch became unresponsive showing the map screen and then rebooted. It took some fiddling to resume the recording (I had to load the course again), but eventually it worked.

As a last resort, I will try 15.77 now, since 20.19 isn't stable either. 16.22 was way (!) better than 19.41 and has been the most stable version yet, but obviously still flawed.

In the 5 years I used it, I never had any crashes on my Fenix 6 pro and I don't know, what's going on with Fenix 7...

I've also just experienced this again today during a run. Also with navigation, bluetooth and ANT+.
On 20.16 on a Fenix 7 Sapphire Solar.

Yet another one for me today 12m into a navigated run - running 20.16 - touchscreen switched off, I even switched off the phone connection today (never have notifications on watch switched on) did 2miles and counting myself "lucky" to have only had one reboot - not liking the sound of 20.19 as it sounds like that reboots in off state - really getting frustrated now - especially as uploading thRAM.txt files doesn't seem to work either - know one thing for sure - this will be my last ever Garmin watch

marathon season starts soon, if this happens to me during the race it will be a definite goodbye to garmin (unfortunately)

I downgraded to 15.77 today and basically it has been a smooth process. However, most of my trusted Apps, widgets & data fields aren't compatible with this firmware version and I couldn't make them work - even with the Garmin Express workaround. 

Therefore, I am back on 16.22 again and hope that at some point Garmin will be able to sort it out in a future firmware update.

I spent much time installing different firmware versions and checking nearly all posts about the maps crashing problem in this forum. 

From what I saw, according to this forum thread (forums.garmin.com/.../repeat-crashing-rebooting-after-16-22-update), the problem seems to have been introduced between 15.77 and 16.22.

All versions after 15.77 including 20.19 still have this problem (to a varying extent, with 19.41 being the worst from my experience).

Maybe this information is worth to be brought to the developer's attention?

There is a buglist that you can post to on the betas but I don't know where it is. I have run into it in the past. I did not run into this particular bug as I don't use maps but you could always just stay on 15.77 which is what I've used going back to around November 2024.

Thanks. I did go back to 15.77, but couldn't make my essential third-party Apps & Data fields work, since those in the meantime have been updated to a newer CIQ Version and are no longer compatible with 15.77. And I don't know where to find and how to install older Versions of those. 

Therefore, I am stuck with 16.22 right now. The following things I will try however going forward:

- manually rebooting the watch after each charging cycle (I hope that resets any cumulating data that perhaps isn't cleared correctly in the firmware and leads to a memory leak, like a broken garbage collector or something. However, this is just a wild guess of mine, but kind of in line with user reports, where the crashes appear only after using the watch for some time and probably after multiple successful recordings).

- disable SatIQ (just out of curiosity to find out, if this has anything to do with the crashing problem)

Other than that, I have no ideas.
