Historically speaking, if I remember correctly, Microsoft has paid phone manufacturers and cell networks to set Bing as the search engine on their smartphones and completely disable the ability for users to change it. I reckon a large part of the reason Google ended up paying to set their search engine as the default on mobile is because otherwise many users would have to jump through hoops every time they searched just to use it. If this goes through, you will use Bing for searches on mobile and you will like it.
