My watch updated overnight to 6.2, heart rate during workouts all over the place. I tried ECG and it’s just a screen of static. Took two restarts to get it back to normal.

Out there...way out there
Seriously? it was broken and I found a fix, Carry on

No, the ECG suffered a disruption that apparently required a couple of restarts to correct.

And since it's working on 6.2 the OS didn't break it. In fact, you've no proof it was the OS upgrade at all.

All you really have here is the cum hoc ergo propter hoc causual fallacy.

Just because you upgraded doesn't mean that's the cause. It may be, it may not be.

You however cannot currently state that it was absolutely the cause. Now, if now other folk start posting that they also had the issue, then now the evidence is starting to back up the assertion.

Until then, your post should be "ECG required two reboots to correct itself after a 6.2 upgrade". But hey, that really doesn't sound as dramatic or sensational, does it?

Just updated to 6.2 and I also have very erratic readings during workouts. Just rebooted the watch and will report back if it clears it.

No luck here, restarts didn't cure the problem. ECG seems to work fine, but whenever heart rate starts to elevate due to exercise wild readings from 60-160 when my heart rate during my workout averages 120. It also loses the pulse quite a bit during the workout and can't pick it up again. Resting heart rate and walking around works fine.

Yeah I’m thinking more that it’s a fit issue against my wrist even though it seemed better before the update. When it’s locked on to the pulse it seems ok. It’s also more reliable it seems with a bit of moisture between the watch and wrist.

Well after all stones have been turned, both wrists, multiple restores, and same result. HR is picked up fine until it gets just over 100 then it loses the pulse. Once I cool down it picks it up again close to 100. Would like to go back to 6.1.3 out of curiosity, but can't.

I read it's not uncommon to see the HR sensor go bad in these watches, which is both frustrating and hard to figure given the hardware should be pretty solid unless a Led burns out or something. Only 3 months old too.

GBNova, this is a known feature/bug that has been around for a while. It isn't new with 6.2. You will have to look it up, but as I remember, ECG doesn't work when the heartrate is between 100 and 120 bpm.

Yes, as stated in the section If you consistently receive an inconclusive result
The ECG app is not ment for workout, but to detect irregularities. If you want to check your workout HR with ECG, use the Pulse App.

Thanks but I'm not having an issue with the ECG, the original poster was. I just have an issue with the HR sensor picking up my HR while exercising.
