      Once again. I still wonder if it’s storage related, surely there’s a reason new firmware stores only about 20 hours worth of activities? I’ve taken a custom to observing watch right at the start and this crash happened within first steps. Screen went black and watch restarted.

        @jussim Just to verify: try to delete all the old activities or perform a factory reset. That should free storage if that is the problem.

          Sure thing! I haven’t done a factory reset yet because I find it a bit too much of a chore to set things up again. But maybe at one point. In the mean time I’ve been experimenting with deleting older activities: trying to find out the point at which the watch starts removing old activities and trying to stay “ahead of it”. Haven’t been too successful, it would seem like…

            Exactly the same happened. Within first steps, before the activity was showing heart rate, the watch went blank.

                @jussim I have been following your painful travel here. All I can think of is that you must have a defective unit. No-one else seems to be experiencing this.

                I will try a few activities with my old S9B (if the new owner agrees to borrow it…) next week and see if I can reproduce it.

                  I was using my S9B few times during summer and autumn and never had a crash.
                  I start to think it could indeed be an isolated defect and not a firmware bug.

                    @freeheeler My son’s S9B just did an awesome job on a 8km hike. With single band GPS it recorded just 20 meters more than Vertical and the difference in steps was only 60. I won’t go into other details as the personal details stored in the watch were not mine and Vertical was connected to HR belt.

                    No crashes, but there was a loooong UI lag after I returned from the activity to the watch display and tried to scroll down to HR display. No HR but blank screen. I doodled for a while and somehow it woke up.

                      Dears, I just want to assure you that this is not an isolated issue. Me myself have reported many crashes and provided logs for lots of them. I am still experiencing restarts. I am just not reporting each and every one here on the forum. Problem was noticed by Suunto and I read in one of previous posts that fix shall come in next FW update.
                      Best way how to avoid crash is to do a soft restart in the morning and the sync the watch then. That works for me and this is the way how I am securing my key trainings or races. I forget from time to time. My watch are so sweet that they remind me that I forgot to do a soft reset. Guess how…? 🙂
                      Have a nice day and keep high hopes for next FW 🙂

                        @zadow Wich software version are you using? Latest?
                        Have you tried to downgrade to a previous version to check if the reboots dissapear or, at least, become less frequent?

                          @zadow Thanks, that is all kinds of assuring 👍 I guess I’ll be doing that in the future! First though I’m going to see how far I’ll get after doing a factory reset.

                            After the last upgrade, I also experienced numerous restarts, which forced me to downgrade and use older but more stable firmware. Since then, everything has been fine.

                              Guess what, five days after the full reset and after eight runs, this happened again. Sheesh.

                                    scroll all the way down, there’s “ibiza” listed and you can find a recent firmware that you prefer.
                                    please note that some of them had bugs, too. but you can download and try.
                                    drag and drop the file unzipped in your sunnto link to downgrade the watch.
                                    hope it helps ✊

                                        It’s been three weeks since the last crash. What changed, then?

                                        I’ve been doing exactly this every couple of days. To be exact, every Monday, Wednesday and Friday morning I reboot the watch before syncing with App. Remarkable, what else can I say!

                                        @Andrija-Paunovic Have you tried the above?
