Fenix 7 pro SS restarts during run.

Hello! I have a problem with my fenix 7 pro SS.

- While running outdoors, the watch restarted twice during work, this run was according to the planned training plan, which then disappears. This was not the first time during a running workout.

- While I was running, I had the HRM Pro chest strap connected to the watch, after the restart the watch started to transmit data from the strap incorrectly.

Firmware 19.41


Does anyone else have similar problems? How can I solve it?

  • We are talking about different issues.

  • This issue has been going on for months. Not related to the blue triangle thing. I backdated my software and it's working properly again.

  • Did you have a reboot in sub-zero temperatures?

  • Not sure as I have experience the Blue triangle crash, did fix# 1, 2, 3 that has not really fixed the problem as when I follow a pre planned route within 4 h it stops, blue triangle than reload maps and end up on « resume training ». Improvement but not fixed. However since I went through the 3 first fix my watch has a hard time to find satellite and sometimes it stops recording, That issue was not existing before I tried to fix the blue triangle widespread crash. I am in long cycling and hiking journey in South East Asia and I definitley can not rely to my watch anymore ( Fenix 7 xpro solar). No access to a computer so counting only on garmin connect to hopefully fix all issues. Not willing to try Fix #4, 5 6….

  • Update February 14, 2025: 

    Our engineers have released software version 20.16 that includes a fix for a potential issue that may cause the watch to crash/reboot when navigating. If you are experiencing this issue, and have not already, you can install 20.16 using Garmin Express. 

    This will not resolve other potential crash/reboot issue, when not navigating. So if you are experiencing crashing/rebooting when not navigating, feel free to reach out to me via Private Message. I would love to help investigate this further. Also is you have installed SW 20.16, and are still have crashing/rebooting when navigating, please let me know. 

  • Any GPS activity regardless of temperature. Would never fail to reboot at least once. I dont ever use it for navigation either, just runs or cycling primarily.

  • Maybe frost affects the battery and because of this the watch goes into reboot. and during running training, run for an hour over the jacket. And its metal body cools more strongly.

  • 20.16 Software was installed on Fenix 7 SS (not pro) yesterday and the watch crashed / restarted while navigating a run today. 

  • Works fine well below freezing, above freezing and everything in between after downgrading software. Temperature has no effect. That's never been an issue
