Fenix 6X Pro - why do my GPS tracks have straight line sections?

That is most unfortunate. I have evidence through many emails discussing this issue with their office here in the UK. They tell me they have investigated and 'cannot reproduce it'. The query was passed onto the tech people in the USA. As they claim not to be able to reproduce the issue they seem to have stopped all further investigation. 

They did want me to report any new tracks as evidence, but I had to tell them I'd sold my 6X and now am using the 7X Solar/Sapphire. If it does anything similar I will let then know. So that has given them the excuse not to go any further with the issue for me personally. This is a shame really.

So far, fingers crossed, the fault doesn't seem to be manifesting itself in my 7X. I used it for a week last month in Scotland in similar scenarios where the 6X would have done the straight-line thing, but all ok with the 7X as far as I can tell.

I did read somewhere that some widgets did strange things to track recording, I can't remember the details. The only one I had on the 6X was a 3rd party data field that allowed me to display a British OS grid reference. My 7X is currently just stock, no 3rd party anything for a while.

Can you share a relevant email excahnge with me? Or can I share your email address with them? It is particularly galling to be told nobody else has reported this issue when I know full well they have!

Hi ! ı already reported it to garmin nearly 1 mont ago when ı saw your post. but they send auto reply 

''Hello Metin,

Good day and glad to assist you with this.

Emails are not via email directly to our customers. To update the software on your fenix 6x you will need to use Garmin Express:

Please review the following: Troubleshooting the fenix 6 Series Altimeter and Barometer

Please let us know if there is anything else we can do to help.''

i have exactly the same problem. altitude gain calculation is sometimes correct and sometimes incorrect. but my going up track record on the map exactly incorrect if ım going slow.

That reply you posted is script generated so you can be sure your report wasn't passed on - sounds like the person didn't understand the issue.

Hi Geoffmozz. Happy to do that. Can we see email addresses here? If so, I’ll send you what I have. If not, you can somehow let me know yours! Sorry this is a late reply. I don’t think I got an email notification of your post …

I've just sent you a 'private message'. Hopefully you'll get a notification for that or similar. Cheers.

Agreed. I'm not convinced any of the support agents I've had exchanges with know how to inspect the data in a Garmin FIT file.

Interesting Dima. Mine used to do it only when moving very slowly uphill on a very steep path or scramble in the mountains, no trees! It happened almost every time. Annoying!

Sold it now to a runner, so he should be ok.

It hasn’t happened once, yet, with the 7X. So Garmin must have done something to their processing / algorithms…?

Under open and clear sky it just happens more frequently, and several quick steps solves the issue for short time. And because I read your previous comment about F7x, I will probably buy it. Greatly increased GPS accuracy is also welcome.
