Speaking of Android, I haven't used any features for people with eyesight disabilities, but I can tell you the "voice access" experience on Android leaves much to be desired. I have a broken screen where only the bottom half is accepting input. Whatever you choose, swap the settings on your phone so you can experience it as he would use it. You will be able to talk him through problems easier, and you will see the common issues with the features that aren't mentioned in documentation.
