From iOS feedback apge

• Formatting of the reference section into two columns is inappropriate for the size of the iPhone screen. The result is 1-3 words per line and excessive wasted space between the columns. On pages that use the template {{Reflist|2}}, it should be suppressed back down to one column. Example: [[w:en:Cepheid variable]] [[User:Bhartshorne|Bhartshorne]] 23:35, 6 January 2012 (UTC)

While this issue is being reported against iOS it easily applies to all phones
