From what I've seen, iPhone is the de facto standard of mobile phones for visually impaired for now, because its VoiceOver function is pretty well made, and more importantly, its UI experience is far less varied than its competitors, i.e. Windows Phones and Androids. It has already a strong community and support from organizations like AFB. I hope this bring them a more healthy competition among the tech companies.
