the reply yes, both official , practical perspective.
people may utilize external inputs (i.e. switches, keyboards, keypads) mobile devices, visually indicating focus still necessary.
visible focus helps users track in content. includes hover , focus states mouse , keyboard touch states. ... means sighted keyboard or keypad users can track progress navigate focusable elements on page mouse users can, , touch users receive confirmation going happen. 2
the guideline stated in wcag 2.0 1 (which applies web content), unofficial mobile guidelines bbc2 , ssb bart group3.
notes: safari on ios , chrome on android both indicate input focus without css outline (with blinking cursor), it's subtle. also, switch controls on ios 7+ , ios voiceover add together focus indicators on elements automatically, these platform specific concerns.
