Fenix 3 HR fw 4.90 - System crash on app start

Efflon

Sorry about your crash. I'm trying to reproduce this on our end. Can you give me some more detail? Did the watch reboot when you powered it on? When you started the app? While the app was running? When you tried to save the workout? Etc. In cases like this it's likely a fw bug, but it could be a bug in your code that was exposed by the update and wasn't handled by the fw properly. The good news is that I'm not able to reproduce this yet so the scope of effect is likely small. The concern is that we don't know what's happening yet. Let me know whatever other info you have so we can try to reproduce this.

Thanks,
- Coleman

Hi and thanks for quick response.
My timeline is this. Running fw4.70 I pushed a update of my app 0.0.11 to the connectIQ store a few weeks ago. The app downloaded and worked fine on the watch. A few days ago I got the 4.90 update and only used the default run/trail-run apps a few times. Then a few days ago I started the app and before even showing any UI from the app, only the Garmin logo is visible for quite some time. I try to press a few buttons and then suddenly the watch is back (rebooted or not I dont' know) to the default watch face. After this I can start the app without any issues.

In this moment when writing this, I again try to start the app an now I get !IQ. The only thing done between the working app and this state has been two runs and one usb connection for pulling the crash log. I again connect to usb for getting a log (without finding one) and then try to start the app, again "Garmin" is showed and then back to default watch face. Yet again I start the app and now it's working just fine...

Below is the next entry from the error log after this las crash...

Could there be memory corruptions or what could be the cause?

If you see the "IQ!", there should also be something in \garmin\apps\logs\ciq_log.txt.

While rare, it could be your app crashed, and the watch crashed as a result of the app crash (the blue triangle), and ciq_log.txt will provide a clue.

Also, have you tried just turning the watch off and back on?

The ciq_log.txt has a really old timestamp and some error messages from my development work. I'll clear it and see if I can catch anything useful.
Regarding watch crash, I don't see the big blue triangle, just the default "/\Garmin" logo, like a restart.
Off and on again happened after the FW update and seems like a last resort to sort out a bug (imho).

How large is your app? on the f3, the stated limit is 64k, but if you are recording a .fit, that takes 4k of that, so your app can only really be 60K. Could you be close to that?
With my apps on the f3, I like to stay at maybe 56k or under to allow for getting too close to 60k.

It's not that big, 41k. I've had other strange issues, such as once the app exited by it self before starting a workout, when changing settings I got a "Gps Ready" popdown from the running app... I'm suspecting hardware memory corruption...

I have the same problem with the Multi Time Zone apps.
The app does not charge and the watch switches off and then on again. This often happens. Why? I do not know where to look for the bug

We have not been able to replicate this issue. We've submitted a ticket with the device team to see if we can find out more about this issue.

We also have similar reports. This is our app:

According to the user, his Fenix 3 HR FW 4.90 reboots after a few seconds with the app open.
