First of all, unfortunately, the watch is no longer guaranteed. So it sucks for me
It started a couple of months ago. Sometimes it turned itself off,
Turned off mean I can switch on but it lost previous HR data baro data, altitude data. temp data. It was strange or me but the settings was remain.
FIrst it made only once a week. I thought there was a program error, So many times I had a reset. But sometimes it turned off daily
What indicated that the compass has not been working for about 1 month.
In the test menu, the physical values are zero in compass
Or lately if it not connected to a phone and turn off then the time will be delayed, was a late as it was turned off.
Other comment, If I was outside in winter and I went into a warm place the instint again turned off.
And unfortunately i found main problem. Plesae see attached link video.

I know it looks Instinct get a big hit but it is not true it is turned off if I drop a bed for example. And it is not a big hit, for this kind of watch. It looks on the second video the small hit is enough fo it is turn off.
So conclusion, IT is not SW problem it just a HW issue. So it need to replace.
The watch is very good and if I will have have money I will replace it because it can be used much better than watches from other manufacturers. So don't stray from him. I read lot of forums and it looks for me this problem have only my instinct. So it is unique issue.
