The book I read to research this post was The Samsung S4 Manual The Complete Galaxy S4 Guide To Conquer Your Device by Daniel Forrester which is a very good book which I bought from kindle. This book is written in an easy to understand way and although it's only 68 pages certainly covers all the basics with this smartphone. The processor is a quad core 1.6 GHZ so is only a small upgrade on the S3 but the memory has gone from 1 GB to 2 GB and the software is much more efficient so the phone is much faster at doing things. It has a rear 13 MB camera and a front 1.9 MB camera and has technology incorporated to let you take several shots and combine them into 1 photo and also there is a built in eraser app that lets you remove moving objects from the background if they are a bit blurred for example. It runs the Android 4.2.2 operating system called Jelly Bean. I think as updates become available you can upgrade that as time goes on as with most smartphones. The case and the bezel to this phone are smaller but the screen is actually bigger which does mean things like the keyboard might take a bit of getting used to as they are bigger than the previous version. I did see a review of this phone in a technology magazine and it was rated as the best smartphone available. I enjoyed reading this book and I know it's quite a new phone but there doesn't appear to be that many books and ebooks available about it although I am sure that will gradually change.

The book I read to research this post was A Newbies Guide To Nexus 7 by Minute Help Guides which is fairly short but a very good book which I downloaded from kindle. I have done a couple of posts on the Nexus 7 at my technology blog at

This is my computing blog but I thought this is a relevant subject for this blog too. The Nexus 7 is a digital tablet which is much cheaper than the current leading tablet the iPad by Apple but has a similiar amount of processing power and on the whole does away with some of the more superfluous features like a sim card in favour of wi-fi & bluetooth which it still uses but also is very cheap for a tablet especially with the features it has. It generally needs a wi-fi network to do things like install apps via your computer or a wireless hotpoint. It's worth mentioning Google were giving away $25 away in the form of a voucher if you joined Google Play for you to download apps and I know currently give away 1 paid app free every day. It's worth noting Google remove any apps that get a lot of negative reviews but don't check them as such like Apple do with the Appstore. It's best to check reviews prior to downloading an app to make sure it's value for money.

The Nexus holds a charge for 300 hours, lets you watch 9 hours of video & lets you read a book for 10 hours when fully charged. It has a 7 inch screen measured diagonally. You can watch video in high definition. I noticed in a technology magazine that rated digital tablets it was 2nd behind the iPad and it has the latest form of the Android Operating System 4.1 and as new features are rolled out you can update that via a wireless connection to the internet. This book keeps it simple & I think was a free or very cheap download but I think if you want something more detailed on the Nexus I would recommend the book Google Nexus 7 For Dummies by Dan Gookin.
