I got one for my dad who is totally blind, and it’s worked out pretty well, but he’s having an issue where if no longer rings (just vibrates). Also, it does not read menu options as he scrolls, so the only way he can make calls is with the quick dial feature. However, all these problems go away when he has his headphones on (it talks and rings just fine with headphones). I have read the Manuel and can’t find any solution. Anyone familiar with this issue able to help? Thanks!
