Mobile phone for someone deaf, partially sighted & with tremor

Share your ideas about the practical side of caring.
My aunt can no longer see her Doro 612 text or keyboard. She only wants to send and receive texts. I've been researching high and low with no luck. Oh and it would also have to have a charging dock because of fiddly Micro USB leads. I'd be grateful for any ideas.
Try checking out RNIb and talking phones. She might be able to use her voice rather than eyes and hands
