Ok, I get a Weekly PDF for my part time job. It is usually around 110 pages. I forwarded it to myself in my gmail account. I managed to open it, using nothing more than the stock abilities of the phone (I guess). Is there a way to search the document? Or do I need to download an App? If so, what APP? I don't need to edit, just be able to read. It is a list of names if that helps.
