1. Yes it's normal. Try report this on huami site, so the they might fix it
2. Only the side push gesture, on both sides at once. Also for a while you can tap on the screen to wake it, for like half a minute after a screen timeout. Otherwise no permanent gesture only lifting the hand

Thanks for the quick reply mate, appreciate it. Was also aware of the side option and the temporary tap/wake thing, hopefully this is another thing they'll address soon.
