For both Android and iOS, most accessibility features are available across standard devices and rarely impact product pricing of the same brand or manufacturer. However, ultra-budget smartphones might face some constraints across features that depend on new functions, are tied to specific hardware, or require higher performance (camera, RAM etc.). For some major brands, we compared 133 accessibility features (see the Product Catalogue Annex and Appendix F) 26 across a sample of smartphones within each brand to provide a representative sense of accessibility feature differences by smartphones, and their relationship with pricing.
A table in the Product Catalogue Annex lists major global manufacturers, their product lines in budget and mid categories and prices27 based on information provided by manufacturers or publicly available information. This list is not exhaustive but is indicative for providing visibility to buyers on potential smartphone product options. Despite minor device-by-device differences, most accessibility features are determined by the operating system.
