Mark Bridge learns about the mobile technology trends at Mobile World Congress 2015 by chatting to James Rosewell of 51Degrees, Dr Kevin Curran from the IEEE and Chris Millington of Doro.

They talk about wearable devices, wireless charging, mobile operating systems and much more... including some of their favourite products from the exhibition.

Canonical, the company behind the Linux-based Ubuntu open-source platform, has announced what it’s calling “the world’s first Ubuntu phone”.

The Aquaris E4.5 Ubuntu Edition is being produced in partnership with Spanish electronics and software company BQ.

Canonical, which leads the open-source Ubuntu project, says the newest version of Ubuntu is the first true mobile release for the platform. Version 13.10 is capable of being run on compatible smartphones and PCs.

OEM versions of Ubuntu-powered mobile devices are now being planned for next year.

The Ubuntu Edge, a high-spec flagship smartphone from Canonical that was attempting to raise $32 million via crowd-funding site Indiegogo, has failed to achieve its target.

In total, over $12.8 million was pledged by almost 20,000 people around the world. Their money is now being refunded.

We start this week's show by discussing the recent quarterly results from Google, Nokia, Vodafone and Microsoft.

There's also time to talk about SIM security, Ubuntu's crowd-funded smartphone, the HTC One mini, smart watches and an unusual process for recharging your phone battery.

By incorporating advanced algorithms and machine learning capabilities, AI can help to optimize a smartphone's performance, providing users with a faster, more efficient and user-friendly experience.

I've been taking a look back at the devices I've written about during the past few years. Some are still faithful companions, others... well, let's just say my faith was misplaced.

Mark Windle, head of marketing at OpenCloud, predicts that this year’s reduction in the number of traditional telecoms operators in some countries will provide an opportunity for other operators to innovate and capture market share in 2016.

He says next year will be a year of rapid change for telecoms… whether it’s MVNO disruption, competitive tariff pricing or simply defence from the ‘dark art’ of hacking.

The most memorable moments in life often go unrecorded. You don't have your camera in your hands. Your finger is still hovering over the 'pause' button on your audio recorder. Or you were simply too busy experiencing whatever was happening. It's all about the one that got away.

That's where Kapture can help.

James Rosewell shows me a colourful roll of paper that's the width of an iPhone but well over three metres long. When I look closer, I can see it's a printed copy of the Wall Street Journal's mobile website. That's a lot of scrolling to do... and a pretty unfriendly user experience for anyone reading the news online. Why does it work so badly?
