Gestures & Touch Settings has received a new update on recently released Windows 10 Mobile Build 10586.338 for Insiders in Release Preview Ring. The update brings visible UI changes to the settings and you can now see Gestures and Touch settings under separate groups.
It also seems to bring back “Flip to silence” feature for the Lumias (which had its support in past) on Build 10586.338 as can be seen in the screenshot above. This update may soon go out to those running Windows 10 Mobile stable release Build 10.0.10586.318.
Thanks @sabriyurga for the tip. Cheers!!
