In Settings, I don't get a significant difference toggling between the middle and high haptic strength options. I'm pretty sure I can tell a difference, but it's subtle. Mind you, I don't feel that either one is extremely weak or anything, they both feel pretty noticeable, it's just that they don't differ much. How is it for you? Do you feel a big difference between the two? Just wanted to make sure this is normal behaviour, and not indicative of the faulty haptic issues that have been discussed. EDIT: I should mention I have the 42mm SGS. Let me know which watch and band you're using.
