Hello, so I got a smartphone for the first time and I choose an android Samsung Galaxy Express, but I still have a week more before the 14 days trial if I want to change my phone for an IPhone 5. So i'm new to all this smartphones and download apps things and when I download an app it shows that it has permisions to access my personal information, messages, my location, network comunication, my accounts, storage, phone calls, hardware controls, system tools, gps?? what is this? is this acceptable/normal? all of my apps are free apps. Is there an app or something that will help me protect my information or maybe block some trying to collect data from my phone and MicroSDHC card? I don't mind If I have to buy an app in order to protect my phone. I also downloaded Lookout. Also, is it safe for me to buy books, games, apps, etc from my android phone? I have never bought stuff online before... Please help me and thanks!
