Sooo as you guys know. I've been buying these watches for some time. Even if they don't work on my tattood skin. I'm very happy to report after getting my GW6 that they finally some what fixed the problem.
1st, wrist detection is to WAKE the watch. Turning it off, simply stops the watch from turning on every time you move your wrist.
I turned mine off immediately as it conserves power. Pushing the back button or the cancel button or turning the bezel also works to turn on the screen.
Not familiar with the tattoo issue.
I like the watch, yet, we're all just the newest bunch of Guinea pigs!
Keep in mind it will not receive phone call notifications. Sadly. I posted about this here in the community and on reddit.
Hopefully my post here in the samsung community will get more traction and get escalated.
