My sister just received the gift of a Vizio M401i-A3 Smart TV and is having a difficult time learning how to use it properly. The main 2 problems she is having are: how to enlarge FaceBook so that she can actually see the photos....AND how can she text someone? Does she need to have a keyboard in order to do that? I have been trying to locate a user manual that can explain in detail the questions she has, but no luck yet. Thanks for any help you can give..... Pamela
