Well that's a bummer! I was
reading here something similar about Air Jump ("Air Jump allows you to scroll through emails or browser pages just by a simple gesture. While this is another great feature, it only works when using the official email client, as well as the official browser on the phone.") and Air Browse (" A bit more reliable, but once again only works with the official Samsung apps."
)
Being a Chrome & Gmail person means I might as well turn these features off and save my battery.
