Watch Active 2 ECG not working

[Iescaunare]

I got the ECG update today (Norway), but I can't get the ECG to work. It just stays on the screen telling me to put my finger on the button. I've cleaned the watch, and moisturized my wrist, but still nothing.

I found a Reddit post telling me how to enter Test Mode. In 2TEST my L-0 value was 6, which they say means some sensor isn't working. Can I do anything about this, or do I have to send it in for repairs?

I too have the GWA2 and am unable to get the ECG to work. Like "tattdmoma" I got code 5 when doing the test. Guess I have a faulty finger sensor. I bought my watch off from a private seller long ago so the warranty option isn't an option.

I just opted to trade the watch in for the new Watch 4. I've been waiting for Samsung/Google to play nice and combine efforts so it's a win for me. I got $150 trade in value which is what I paid for the watch long ago anyway. Now let's hope the new watch doesn't have any issue!

I am having the same issue but I cannot find out what the test is, I am able to go into the testing mode but cannot figure out what to do after. would it be in the HRM button?

The option is "2Test"

Just adding my same issue to the pot. I'm getting a L-O value of 5. Everything seems to work fine  except the ECG. Worked for about 2 months after the update. No longer in warranty so I'm stuck with it.

İ have the same problem i get 5 in the L-0 value. But after i read the comments here i went to a tech Shop and I reviewed the Galaxy Watch 4 display product and look from the menu to L-0 value. İt was allso 5!!! How is it possible on a unused new product???
