Android Advisor Magazine Issue 4 Edizione posteriore

Android took the smartphone and tablet world by storm, but Google isn't stopping there. With its Nest smart thermostat it's found a way into our homes, and with Chromecast it's sat down in front of the TV and made itself comfortable. But it's more than welcome: its media-streaming dongle can turn any old TV into a smart TV, and at just £30 that makes it a game changer. We explore Chromecast in depth.

Google has competition in the TV space, however. Most recently from Amazon, in the form of its Fire TV streaming box. This device has yet to make its way to the UK, but if the US pricing is anything to go by Chromecast has little to fear.

Let's not forget Android TV, a version of Android optimised for your TV. Read all about it in Android Advisor.

Also in this issue we explore the emerging trend of dual-SIM smartphones. These devices are far more popular in other corners of the world, but UK users could also benefit from having two SIMs. We've also rounded up some of our favourite dual-SIM devices.

Many of the innovations we're seeing in mobile tech concern health and fitness, but are we at the point where your phone or tablet can replace your family GP? We find out.
