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.

ABI Research says consumers are suffering because conventional smartphone components are being used in smart watches, even when manufacturers claim otherwise.

Its ‘teardown’ service reports a lack of optimised smartwatch components, resulting in the end user experiencing sub-optimal battery life, unnecessary costs and a device that’s bulkier than it needs to be.

This year's Mobile World Congress was notable for the number of product launches by handset manufacturers. To get a better understanding of smartphone manufacturing, we spoke to Johan Lodenius of semiconductor company MediaTek.

He gave us a simple overview of how 'fabless' manufacturing works, discussed developments in smartphones and wearable devices, contemplated the end of the PC era and talked about the importance of driving costs down.

Even though the first mainstream 64-bit mobile processor was only launched towards the end of 2013, new figures from ABI Research show this type of chip will dominate the mobile market within the next five years.

Apple’s 64-bit A7 processor had been shipped in more than 36 million iPhones and iPads within the first three months of launch. It was followed by Intel, Marvell, MediaTek, Qualcomm and Nvidia all announcing their first 64-bit mobile processors at Mobile World Congress 2014.

Strategy Analytics has published information about the major companies producing applications processors for smartphones during 2013.

It shows that Qualcomm remains the leading producer of smartphone processors and is also the second-largest tablet chip producer as well.

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?

This week we're talking about two big announcements from BlackBerry: a luxury smartphone and some major management changes.

We also discuss the latest Samsung/Apple patent ruling, Vodafone's new mobile wallet, Android licensing, Doro's anti-virus deal, BYOD and the rise of the 'selfie'.

With more than half of all pre-teen children reported to be using text messaging as their main form of mobile communication, it's not surprising to hear that bullies are taking advantage of SMS to attack their victims.

But what can mobile networks do to help these victims of cyber-bullying?  Louise O'Sullivan of Anam Technologies explains why she thinks network operators are apparently reluctant to take action - and why other organisations need to get involved.

This week's headline-grabbing product launch is the Motorola Moto G, which promises a decent Android smartphone at a very attractive price.

We also discuss new rules about mobile phones on planes, a new campaign to ban hands-free calls in cars, falling SMS revenue, mobile wallets and BlackBerry's $1 million investment.

The past few days have been a good time for launches. Twitter has floated on the stock exchange, Kazam has revealed its smartphone range and EE has created a tariff with a million gigabytes of mobile data.

On the other side of the coin, Acer's CEO is quitting, Vodafone UK has missed its 3G coverage target and hackers can take control of your handset's camera to ascertain PIN codes.

It looks like BlackBerry is safe for the moment... but not with the takeover many had expected.

Meanwhile Google launches the Nexus 5, Nortel's patents are sent into battle, EE promises ever-faster 4G, the FAA allows electronic devices to be used throughout flights and we celebrate a record quarter for smartphone shipments.
