Smartphones of the year: clarity at the high-end

Published

on

It’s been a wild year in smartphones, with a vast range of new options spelling great confusion in consumer choice. But ARTHUR GOLDSTUCK has no confusion about his high-end phone of the year.

Smartphones become so much more powerful and more aesthetically pleasing every year, it becomes increasingly difficult to choose a stand-out device. Overall features and functionality barely differ from one flagship handset to the next. The result is that one tends to focus on a specific feature or aspect of the phone that stands out from the rest.

This column’s choice of smartphones of the year come down to devices that have exactly that: a stand-out feature or function. This selection excludes phablets – phones with 5.5-inch or larger displays – and focuses on standard-format phones, i.e. smaller than 5.5-inch.

Smartphone of the year: Samsung S6 edge

SM-G925IZDAINS-625537-0

The Samsung S6 edge is my choice for smartphone of the year for two compelling reasons. As phones go, it is a beauty to behold. The curved screen edges represent the most significant departure in phone design this year, making it practically the only phone of 2015 to break out of the rectangular block mould.

Initially, the utility of the edge screen was dubious, but once the software was updated to allow apps as well as contacts to be displayed on the edge, it came into its own. It should be said, however, that far more was expected in terms of utilities that specifically took advantage of the format of the secondary screen. There, users are still disappointed.

There has been compensation for this, however, in the dazzling quality of the Super AMOLED display and of photos taken with the 16 MP camera. I have yet to see a phone camera that matches this one for quality and clarity of images. The one-touch automatic light adjustment for shaded images offers almost the equivalent of the LG G4’s manual controls for exposure adjustment. The latter still has the, err, edge in manual settings, but can’t match the S6 for consistent quality in automatic mode.

How does the S6 edge match the Sony Xperia Z in this category, despite the latter’s eye-popping 23MP camera? For one thing, the size of the camera’s sensor plays a bigger role than Megapixels at this level, and both camera’s sport 1/2.6” sensors, as does the G4’s 16MP camera. However, when all else is equal, the software behind the image processing is all-important. Here, Samsung appears to have spent an inordinate amount of laboratory time in ensuring it brings the cutting edge to all its flagship phones, including the S6, S6 edge+ and Note 5, all of which share the same camera specs.

Those for whom high quality photography on the fly is make-or-break on a phone, it will be difficult to look past this one. If aesthetics is their reason to buy the phone, they may want to take heed of a cautionary tale: one cannot keep that gorgeous curved screen in pristine condition without a flip cover. That means its aesthetics will rarely be exposed, except to the user. In other words, not great for those who want a phone for status. I’d be quite happy to enjoy it privately.

Runners-up

The runners-up are all superb phones, but most suffer by their lack of significant advances over previous models.

#2. iPhone 6S

One can tell that Apple is running put of ideas when it calls its latest phones “the most powerful iPhones ever”. What, a new iPhone would be LESS powerful than the previous model?

Of course, almost every element is improved over the iPhone 6. Of course, it is a better version of a phone that was already superb. And of course, it is a must have for a die-hard iPhone user.

To the casual observer, however, it is the same phone, and it would be absurd to regard it as the best phone of the year. “Second-best” sounds like an insult, but it remains a magnificent device, with a 4.7” screen featuring force touch functionality.

First seen in the Huawei Mate S, touch sensitivity is taken a step further with 3D Touch on the 6S, which allows functionality like previewing content before opening it, from email to Instagram to map locations. That would be enough to keep Apple fans coming back.

#3. Sony Xperia Z5

If it’s good enough for James Bond, it’s good enough for, well, Xperia fans. It has a similar look and feel to the previous editions, from the Z1 through to the Z3+. Sony skipped the Z4, almost as if to say this is a leap in technology.

The main spec change is the camera going from 20 to 23MP and its sensor size increasing from 1/2.3” to 1/2.6”, while the device also becomes even slimmer, from 7.3mm down to 6.9mm. A fingerprint sensor is added, bringing it up to speed with Samsung and Apple competitors.

The camera puts it ahead of the iPhone for photographers, but Sony needs to come up with a real step change rather than tinkering at the edges to be a stronger contender for phone of the year.

#4. HTC OneM9 +

Like Sony, HTC has also found itself in an arm wrestle of evolution from great previous models to even better new ones. The One M9, like the Xperia Z3+, represented a holding pattern, but the new One M9+ breaks formation. It has a magnificent display, with its 1440 x 2560 pixels and 565 ppi pixel density beaten only by the Samsung S6 phones, and then only marginally.

Like the M9, it has a massive battery, at 2840 mAh, but that translates into a thicker phone, at 9.6mm, which can feel positively clunky against the competition. It stays with a 20MP camera, introducing a second 2.1MP Duo Camera on the rear, but this doesn’t translate into image quality that competes with the Samsung and Sony options.

Earth 2050: memory chips for kids, telepathy for adults

An astonishing set of predictions for the next 30 years includes a major challenge to the privacy of our thoughts.

Published

on

Buy 2050, most kids may be fitted with the latest memory boosting implants, and adults will have replaced mobile devices with direct connectivity through brain implants, powered by thought.

These are some of the more dramatic forecasts in Earth 2050, an award-winning, interactive multimedia project that accumulates predictions about social and technological developments for the upcoming 30 years. The aim is to identify global challenges for humanity and possible ways of solving these challenges. The website was launched in 2017 to mark Kaspersky Lab’s 20th birthday. It comprises a rich variety of predictions and future scenarios, covering a wide range of topics.

Recently a number of new contributions have been added to the site. Among them Lord Martin Rees, the UK’s Astronomer Royal, Professor at Cambridge University and former President of the Royal Society; investor and entrepreneur Steven Hoffman, Peter Tatchell, human rights campaigner, along withDmitry Galov, security researcher and Alexey Malanov, malware analyst at Kaspersky Lab.

The new visions for 2050 consider, among other things:

  • The replacement of mobile devices with direct connectivity through brain implants, powered by thought – able to upload skills and knowledge in return – and the impact of this on individual consciousness and privacy of thought.
  • The ability to transform all life at the genetic level through gene editing.
  • The potential impact of mistakes made by advanced machine-learning systems/AI.
  • The demise of current political systems and the rise of ‘citizen governments’, where ordinary people are co-opted to approve legislation.
  • The end of the techno-industrial age as the world runs out of fossil fuels, leading to economic and environmental devastation.
  • The end of industrial-scale meat production, as most people become vegan and meat is cultured from biopsies taken from living, outdoor reared livestock.

The hypothetical prediction for 2050 from Dmitry Galov, security researcher at Kaspersky Lab is as follows: “By 2050, our knowledge of how the brain works, and our ability to enhance or repair it is so advanced that being able to remember everything and learn new things at an outrageous speed has become commonplace. Most kids are fitted with the latest memory boosting implants to support their learning and this makes education easier than it has ever been. 

“Brain damage as a result of head injury is easily repaired; memory loss is no longer a medical condition, and people suffering from mental illnesses, such as depression, are quickly cured.  The technologies that underpin this have existed in some form since the late 2010s. Memory implants are in fact a natural progression from the connected deep brain stimulation implants of 2018.

“But every technology has another side – a dark side. In 2050, the medical, social and economic impact of memory boosting implants are significant, but they are also vulnerable to exploitation and cyber-abuse. New threats that have appeared in the last decade include the mass manipulation of groups through implanted or erased memories of political events or conflicts, and even the creation of ‘human botnets’. 

“These botnets connect people’s brains into a network of agents controlled and operated by cybercriminals, without the knowledge of the victims themselves.  Repurposed cyberthreats from previous decades are targeting the memories of world leaders for cyber-espionage, as well as those of celebrities, ordinary people and businesses with the aim of memory theft, deletion of or ‘locking’ of memories (for example, in return for a ransom).  

“This landscape is only possible because, in the late 2010s when the technologies began to evolve, the potential future security vulnerabilities were not considered a priority, and the various players: healthcare, security, policy makers and more, didn’t come together to understand and address future risks.”

Pizoelectrics: Healthcare’s new gymnasts of gadgetry

Published

on

Healthcare electronics is rapidly deploying for wellness, electroceuticals, and intrusive medical procedures, among other, powered by new technologies. Much of it is trending to diagnostics and treatment on the move, and removing the need for the patient to perform procedures on time. 

Instruments become wearables, including electronic skin patches and implants. The IDTechEx Research report, “Piezoelectric Harvesting and Sensing for Healthcare 2019-2029”, notes that sensors should preferably be self-powered, non-poisonous even on disposal, and many need to be biocompatible and even biodegradable. 

We need to detect biology, vibration, force, acceleration, stress and linear movement and do imaging. Devices must reject bacteria and be useful in wearables and Internet of Things nodes. Preferably we must move to one device performing multiple tasks. 

So is there a gymnast material category that has that awesome versatility? 

Piezoelectrics has a good claim. It measures all those parameters. That even includes biosensors where the piezo senses the swelling of a biomolecule recognizing a target analyte. The most important form of self-powered (one material, two functions) piezo sensing is ultrasound imaging, a market growing at 5.1% yearly. 

The IDTechEx Research report looks at what comes next, based on global travel and interviewing by its PhD level analysts in 2018 with continuous updates.
