Last summer, Samsung announced the high-spec Samsung Z, which it described as “the first commercially available smartphone powered by the Tizen platform”. However, the launch was postponed and the phone’s release apparently cancelled in favour of a focus on lower-spec devices.

Samsung has now announced a new Tizen smartphone: the Samsung Z1.

The dramatic growth in smartphones running the Android Open Source Project (AOSP) platform or other ‘forked’ versions of Android is expected to slow next year, according to a report from ABI Research.

Devices that run forked or AOSP versions of Android don’t have direct access to the Google Play app store, unlike those produced by the Open Handset Alliance.

A new quarterly report from ​ABI Research show that shipments of ‘forked’ Android smartphones - those that use the Android Open Source Project rather than Google’s own version of Android - accounted for 20% of the smartphone market in Q2 2014.

Shipments of AOSP smartphones increased by 20% from the previous quarter, while the total market grew by just 3%.

Although smartphone sales don’t have the dramatic year-on-year growth they once had, ABI Research has published a new report that shows these sales figures are still increasing.

It expects 1.25 billion smartphones to be shipped this year, with smartphone shipments forecast to pass the 2 billion mark in 2018.

Nokia has sold most of its Devices & Services business to Microsoft, as originally announced in September last year. The deal also includes an agreement to license patents to Microsoft.

Although the deal was originally worth €5.44 billion (£4.48 billion), Nokia says it now expects the total transaction price to be slightly higher than this.

The adage that “the customer is always right” has apparently been disproved by a recent survey of mobile phone users.

Mobile News reports that virtual networks Virgin Mobile and Tesco Mobile outperformed their network partners in a recent customer satisfaction survey carried out by research firm YouGov for price comparison website uSwitch.

I knew I’d seen it before. Towards the end of last week I read about a study from the Department of Computer and Information Science at the University of Pennsylvania that said it was pretty easy to identify passwords from smudges on touchscreen mobile phones.

Yesterday I received the following text message from O2: “You’ve gone over your data allowance on your mobile. You need to cut down or get a bigger Bolt On to keep using the internet.” I thought this was strange as I’ve an unlimited data bolt on applied to my O2 UK contract so I decided to telephone O2 customer services to find out a little bit more. Here’s what happened.

This week's Carnival of the Mobilists – the best mobile blogging (and podcasting!) of the last seven days – is online at Tam Hanna's new TamsBada site. As always, you'll find a wide variety of mobile-related subjects and discussions.

Supermarkets. You either love ‘em or hate ‘em. Actually, that’s not true. Most of us seem to be happy enough with a half-price bottle of wine but less convinced about globalisation and supplier relationships.

But none of that’s bothering me today. Instead, I’m troubled – as I have been for several months – by the TV commercial for Tesco’s prepay mobile phone tariff.

Iain Graham, James Rosewell and Mark Bridge return to review their mobile industry predictions from last year. Which mergers, partnerships and developments did they forecast correctly... and which didn’t work out as planned?

Later in the programme, the team anticipates some of the topics that will be hitting the headlines during 2016.

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.

We're taking a look back at the biggest mobile industry news stories from February 2015, including allegations that the UK's security service tried to breach SIM card security by hacking into one of the world's biggest SIM producers.

We also talk about the planned BT and EE merger, the creation of two new UK virtual networks, some acquisitions in the mobile payment arena and a new Ubuntu smartphone.

In today's programme Mark Bridge talks to Chris Millington, who's Managing Director for Doro UK and Ireland.

They discuss the state of mobile retailing in the UK, the future of wearable devices and - as you might expect - smartphones for seniors.

We're back with a month of mobile industry news, including takeover talks and takeover rumours. O2 and Three are said to be discussing a merger... but is there any truth in the suggestions that BlackBerry could be up for grabs?

We also discuss Apple's record-breaking quarterly figures, the highlights of CES and the launch of Microsoft Windows 10, as well as saying farewell to the current version of Google Glass.
