The Mobile World Congress, which takes place annually in Barcelona, is usually dominated by smartphones. Grabbing headlines this year, however, is the Pilot earpiece and its promise to instantly translate languages: a real-life version of the Babel Fish from The Hitchhiker's Guide to the Galaxy. It is not the first time that elements of science fiction from Douglas Adams's story have subsequently become science fact. The technology that allows the Hitchhiker's Guide to be operated simply by brushing with one's fingers is now familiar from smartphones and tablets. The information the Guide stores, meanwhile, is user-generated, and constantly updated; the approach adopted by Wikipedia.

Taking a look back at seven days of news and headlines across the world of Android, this week's Android Circuit includes Samsung's efforts to spoil MWC, new images leaked of the Galaxy S8, asking if the new Nokia handsets are worthy of the Nokia name, a hands-on review of the Nokia 5, the LG G6 design, Huawei's new camera technology, the return of the BlackBerry keyboard, and the designer of the Psion PDA returning with an Android dream machine. Android Circuit is here to remind you of a few of the many things that have happened around Android in the last week (and you can find the weekly Apple news digest here). Although it had previously declared that it would not be announced the Galaxy S8 at this week's Mobile World Congress in Barcelona, the South Korean company announced when it would be announcing its new flagship. It looks like a tactical move to remind consumers not to fall in love with the new devices from MWC until it can consider Samsung's latest: But today's news about the Galaxy S8 launch wasn't about reassuring the public. It was about taking away some of the momentum that the S8's rivals could gain from Mobile World Congress.

Masayoshi Son, chief executive of SoftBank Group Corp., believes that within 30 years, artificial intelligence will be smarter than the human brain. The Wall Street Journal reports that Son made the prediction at Mobile World Congress, the telecom industry's biggest trade show, which is currently being held in Barcelona, Spain. Not only does Son think that super smart robots will outnumber humans in 30 years, but more than a trillion objects will be connected to the internet. "That is why I'm in a hurry to aggregate cash to invest," he said. SoftBank has made quite a few recent deals, including purchasing British microprocessor designer ARM Holdings PLC for $32 billion, as well as U.S. asset manager Fortress Investment Group PLC for $3.3 billion. Son plans to ramp up the research-and-development funding for ARM, which designs the basic architecture for chips in more than 95 percent of smartphones around the world.

That's a phrase none of us has uttered yet, but the day when voice assistants go beyond helping us simply complete transactions to facilitating deeper human-to-human relationships is rapidly approaching. In fact, Amazon and Google are rumored to be adding voice calling to Echo and Google Home. While today people might ask Alexa for their bank balance, voice is ultimately about human conversation, which might lead you to doing something like connecting with your financial advisor. The news that Amazon and Google are working on adding voice calling to Alexa and Google Home isn't a harking back to simpler times, nor is it a concerted effort to kill the home landline. Rather, it's an acknowledgement that while voice assistants are great at completing transactional tasks, people still want to have human conversations, such as getting someone's opinion or walking through a complex purchase.

If Google has its way, it might be bringing its virtual assistant to other smartphone platforms. In an interview at Mobile World Congress, Gummi Hafsteinsson -- product management director at Google -- said it wants to port Google's virtual assistant to competing smartphones according to a report from Geekster. "I do not think we have anything to announce at this point," Hafsteinsson said. "But I think the general philosophy is that we would like to have the Assistant available to as many people as possible." Hafsteinsson's statement followed Google confirming that Google Assistant would be available on Android TV and Android Auto platforms.

The Google Assistant feature was finally rolled out to Android Nougat and Android Marshmallow devices on Thursday. But to get the feature on your device, you will need the updated version of Google Play Services, which wasn't available on the Google Play app store at the time of writing. If you haven't received the update on your device, or for some reason, can't seem to get the feature on your device, there is another way out. Users who haven't received the feature but still want to access it will need to download the APK version of the update and install. Note: International Business Times cannot be held responsible if anything goes wrong.

If you have an Android phone running Android 6.0 Marshmallow OS and above, check it, you might have a new feature available -- the Google Assistant is now rolling out to all such devices. It is different from Google's previous voice offerings such as Google Now since it not only lets user conduct conversations with it, but also evolves according to usage. The rollout, which will occur in the form of a Google Play Services update, was announced last week. Gummi Hafsteinsson, Google Assistant product lead, said in the company's official press release issued on Sunday: "Our goal is to make the Assistant available anywhere you need it. It came to Android Wear 2.0--via new smartwatches--just a few weeks ago and, as we previewed in January, the Assistant is also coming to TVs and cars. With this update, hundreds of millions of Android users will now be able to try out the Google Assistant."

Google is about to make more Androids even smarter. The tech giant is rolling out its Google Assistant to devices running on the Nougat and Marshmallow versions of its Android software. The firm first revealed the expansion at the Mobile World Congress and users in the US will be the first to receive the update – Australia, Canada, the UK and Germany are set to follow.

Voice assistants are software programs that respond to voice commands in order to perform a range of tasks. They can find an opening in a consumer's calendar to schedule an appointment, place an online order for tangible goods, and act as a hands-free facilitator for texting, among many, many other tasks. Technological advances are making voice assistants more capable. These improvements fall into two categories: improvements in AI, specifically natural language processing (NLP) and machine learning; and gains in computing and telecommunications infrastructure, like more powerful smartphones, better cellular networks, and faster cloud computing. Changes in consumer behavior and habits are also leading to greater adoption.

Line Corp., owner of Japan's most popular messaging service, is getting into the artificial intelligence market in a big way by outlining an ambitious plan that pits it against the likes of Google, Facebook and Amazon. According to a report in Bloomberg News, Line Corp. is gearing up to launch a suite of AI software tools that will enable a digital assistant that speaks in Japanese and Korean. The assistant will be able to converse with users and provide weather and news via a dedicated smartphone app or a speaker that sits on the table and is called Wave, similar to Amazon's Echo. Line Corp., which unveiled the strategy during the Mobile World Congress in Barcelona, Spain, this week, said both the app and the speaker will come to the market between April and June. While Line faces a lot of competition, the company thinks it can stand out from the pack because of its local knowledge about the markets in which it is operating, including South Korea, Taiwan, Thailand and Indonesia.
