I posted this in another thread this morning but I thought it was worth putting it in one of its own, as this is a regular topic that many Garmin Swim watch users, including myself, seem to have problems with!
Here's what I said:
Hi Stemik
I have NEVER had accurate stroke type detection with the Garmin Swim, with either the 3.4 or 3.6 watch firmware. Like you, I always find that the watch detects my freestyle as backstroke.
However, more recently I have been working on my stroke style after watching some YouTube videos from the Swim Smooth team:

The ONLY change I have tried to make is to stop the 'S' shape my hands and arms make after entering the water, as you pull on the water. I also try to ensure that my hands enter the water without going over the centre line of my body and that the hand travels down the side of my body rather than directly below my torso as this causes more of a wobble in the hand and arms.
This is not easy if you have swum with the same technique for years and you are 'hard wired' to do your freestyle stroke this way. In my case I'm 45 years old now and have swum the same style of freestyle for 25+ years...
I think that the slight change in swim technique for freestyle makes me swim a little bit slower, but I plan to stick with this until I get the hang of the change as I know I will get faster again with practice.
More importantly, changing my technique (only slightly) has made a massive difference to my watch's ability to correctly detect the stroke.
In the link below my first interval this morning was 80x 25m freestyle. Today, out of 80 lengths just 3 were detected as backstroke. Usually most are incorrectly labelled as backstroke! The improvement in detection therefore seems to be all down to my trying to adopt a better swim style for my arms, as demonstrated by the Swim Smooth team.

Now I would be the first to say that it's a REAL PAIN to have to re-learn your technique... especially if it's one you're used to for many years. But, I suspect that in the long term, improving your technique in freestyle will be more beneficial than getting the watch to be more forgiving of incorrect swimming style.
Until I watched the videos and critically analysed how I swim my freestyle, I was convinced that the fault was the watch and that my technique was great. Wrong!!! Now I know, however reluctantly, better.

And here's a helpful (or at least it was for me) video:

Hope that's helpful to some out there...
