I have never heard of them fixing phone screens and have never seen an area in the store for that.
There is a place on Bass Road across from the McDonald's that fixes phone screens I do not know about televisions. I don't think they have this available at the store though.
Probably not, most geek squad does is usually send it off. There are a lot of different phones. They might send it back to the company for you.
Not sure, but the geek squad does more than they used to..
