I have been updated on W10M now. When I was on WP8.1, I disabled double-tap to wake up option. Now I want to re-enable that option but I couldn't find that option. I have searched all over including extras & info but now there's no such option. I am really wondering where had that option gone. What should I do now ? My phone's L535DS running Windows 10 Mobile if relevant.
settings => Personalization => Lock screen does not have any option:
And in Extras I can't even find Touch option.
