I've been using a mobile device for programming since 2012 and I developed a mobile text editor and screen keyboard that I use myself. I think I have the richest experience here. The problem is that the people who create mobile input interfaces developed them on a computer in order to make a “product” for a company, not for people. This is also due to patents and other problems not related to this task like "It’s not the flashy feature that shifts your Net Promoter Scores"
