A little tutorial on swipe to look controls for your mobile game: https://youtu.be/GAomDzu54vk
No voice. Still too shy to talk on internetz. 
Awesome!
I also add one more branch to detect swipe only in one side of screen.
I wonder if it possible to make own, custom joystic in UMG (or swipe-to-go blueprint). In mobile devices I get small issue - not always UMG and Virtual Joystick works correctly (one of them stops to react, and you need to take over fingers from screen and reactivate again (put on screen)).
I dont exclude that it my “Tegra note 7” device is react that way.
Sorry for bad English, cheers!
For umg I never use buttons. Idk why but they never seem to work the way I want. I use borders instead.
