Ok, I think I know. If you do "hold to aim" on phone and get a shoot very quickly it does no bonus dmg and it continues to give no bonus dmg even if you hold the zoom in. If you do manual zoom in, or miss the first shot in "hold to aim" mode and then hit another the bonus applies. But also sometimes it just works. I could blame it on "it needs at least x seconds in zoomed mode to work" if not for what you can see on the video, repeated no bonus dmg on same mob even though still zoomed in. Then, once I miss or hit other mob first the bonus applies fine.
This doesn't seem to apply to Joseph in tactics 9. Once you're zoomed in it applies the bonus fine, only mobs in gigalink seem to have issue.
