Watch 7 heart rate sensor issue

[CSevo81]

I'm posting again to raise awareness for anyone thinking of upgrading to the Watch 7 (or in my case downgrading)

I recently traded my Watch 5 Pro for the Watch 7 and have noticed after 2 weeks of workouts I am losing around 25-50% of the heart rate monitoring each time. The drop outs are so regular I unfortunately can't get good workout data now. My calories burned each workout has dropped significantly due to the heart rate not being recorded . Check out the picture I've circled the times it dropped out overall 30 minute circuit training session.

It mentions the wrist strap may not be on firm enough. The issue is my strap is the the same strap as my Watch 5 Pro , same work outs never had this problem, see screenshot from a recent session on my Watch 5 Pro, no loss of heart rate data

The Galaxy watch 7 Ultra is the same. It can barely measure heart rate whilst exercising. Even at low(ish) intensity. Sometimes it's OK but most of the time it has problems.

It only seems to be able to measure heart rate accurately at rest.

I thought the Galaxy Watch 7 was supposed to have a more accurate sensor than previous models.

I traded in my watch 5 for the 7 recently.  Just tracked my first workout and I agree that the watch 7 is inferior to the 5.  The 7 kept losing my heart rate all along a 6 mile hike, for several miles of the hike I have no heart rate data.  This never happened with the 5.

I've just been given the Samsung active watch 7 for Christmas and my heart rate according to the watch fave has been 103 for 6 hours yet when I do the ecg reading but putting my finger on tbe button the reading is only in the 70s. Something not right there

Any idea if this has improved.
