Hi. I got this SGT in January,my first smart phone. I wanted to use it to view PDF files,most normal size phones are too small to view diagrams or read whole paragraphs without having too scroll around. At first I played a few games but this has never been of much interest to me. I have started to find really usefull aps like cam scaner l can use it copy drawings etc on site then email in just a few simple steps,it can take high detail pictures showing part No then email to get the right part 1st time (A picture paints a thousand words).I have also been using it to record work times just like clocking in & out. For anyone looking at differant phones/tabs I have had no problems with anything not working on this samsung I have found it is very intuative, if it did'nt work 1st time then I just move on. If anyone finds Plumbing or heating engineer apps please pass them on
