The samsung galaxy s4 is the most technologically advanced smartphone currently available and is also one of the most popular. This book is a good guide to its features and as with a lot of smartphones the documentation with the phone is a bit brief so I think this book is a necessity for the potential owner. It has an eyescan feature so if you are watching a film and look away it pauses the movie until you look back at the screen. It also if you are reading an ebook will let you advance forward or back a page by merely swiping your fingers across the screen without actually touching it. It can recognise your face which is part of the security set up on this phone and often this will be in conjunction with a pin or password for increased security. When you look at the screen it lights up and when you look away it powers down which is much better than the going into standby of conventional smartphones. The sensor on the phone also optimizes the picture displayed according to where you are looking. Many android apps are made exclusively for this phone and as a result have increased functionality. The google play store is the most popular android app selling website. You do have to watch out for rogue apps probably more on the less well known selling websites and should always watch what information is being collected by the app and whether it's doing things like dialing out for no apparent reason. Many of the selling points do scan apps for malware but you have to be careful. Always check the reviews and only use apps that are fairly well established or come from well known developers.
