Bro i took a Moto F3 for my father and then a Moto F3 for my Granny.
It has a LCD like Calculator, ( Gud for those having Eye side problem )
Here is the link for this phone :

it also has a feature like when you press any button a voice guides you.
there are three languages ( voice ) support for this phone.
URDU, English, Punjabi...
when you want to delete any sms it says : message nu mitaan wastay utay jaan walay button tu dabiyaa... hahahaha
but i really hate its screen.. this phone is no more available in market but if you are interested i can try (not promise )to get this phone for your mom.
