Telephone

I want to buy a new telephone. I don't really know what kind of telephone but it has to be a smart phone. That I know. But which model of brand is the question. I think I am going to a telephone shop and ask them to give me some good advice. I don't feel like reading of these different brochures. I just don't want to spend too much time on it. Or maybe I let my son take care of it. He loves to know everything about telephones and smart phone. Maybe he can have look on the internet. There you can find all the technical details. And I want a good looking one. Not too big and not too small because I want to put the telephone in my pocket but I also want to have a nice size screen which I can read without spectacles. Now I am writing I know what specifications it must have.
