Best thing about Tizen is notifications even if phone screen is on
Maybe this was available on recent Touchwiz ROMS and I wasn't aware since I had been on Null since v07, but since upgrading to Tizen, apart from the overall smooth UI, the best thing I have noticed is that notifications appear on the Gear even when the phone screen is on.
It didn't used to do that on Android for me.
This is so useful when in a full screen app like a game, watching a video etc. where you can't see the notification bar. Now, I don't need to stop what I'm doing to decide if a notification is important or not.
Thought it might be useful info for someone not sure about whether to make the move to Tizen.
