I may want to buy the S2 (but looking at moto 360 2nd also). What I would like to know is when you get a notification on the S7 (and enabled it in the gear app) how does it appear on the S2? Does it depend on watch face? What I would like is a pop-up, vibrate, turn screen on if was off (and stay on at least for a while). I read to view notifications you need to rotate the dial but I wasn't sure how you know what you got to begin with. I think AW has a notification card that pops up (?). I also just read in a thread that they can be hit or miss like if the watch is sleeping or something. Main reason I want a watch is I don't always feel the S7 vibrating and I miss a call or notification, so having this vibrate also should help. Also how is the strength of the vibrator?
