Board Thread:Support Requests - Designing Your Wikia/@comment-5558012-20160328192131/@comment-168424-20160328233646

Sound definitely like a Special:Contact/general question. Wikia is not great about communicating how the mobile skin works and I've seen almost literally nothing about touch screen specific support.

In the mean time, I would guess that the touchscreen specific stuff is keyed to your browser user agent string (http://whatsmyuseragent.com), so if you could try different browsers or add an extension to spoof different user agents, it would be interesting to know how that affects your experience.
