OnePlus and Meizu have been cheating benchmarks for some reason

Why are manufacturers still cheating on benchmarks?

An XDA Developers investigation in cooperation with our friends at Primate Labs, the company behind the excellent Geekbench test suite for Android, has uncovered a vast conspiracy of benchmarking infractions across thousands of Android devices.

OK, that’s not entirely true, but it sounds good, right? In reality, it was discovered that, as Samsung, HTC and others were found to be doing a number of years ago, OnePlus and Meizu have been activating “performance” modes on their flagships, the OnePlus 3T and Meizu Pro 6 Plus, when entering some CPU and GPU benchmarks. From XDA:

We came to the conclusion that OnePlus must be targeting specific applications. Our hypothesis was that OnePlus was targeting these benchmarks by name, and was entering an alternate CPU scaling mode to pump up their benchmark scores.

The OnePlus 3T was looking for Geekbench, AnTuTu, Androbench, Quadrant, Vellamo, and GFXBench. As by this point we had fairly clear evidence that OnePlus was engaging in benchmark cheating.

XDA Developers worked with Primate Labs to obtain a special build of Geekbench that wouldn’t trigger the cheating, and found significant performance differences and, of course, higher overall temperatures as a result. Similar results were found with the Meizu Pro 6 Plus, which isn’t popular outside of China.

For its part, OnePlus says that there was no malice intended in the optimizations, and that they were meant to improve overall game performance, not benchmarks, at the expense of a bit more heat output and battery usage. A future build will remove the benchmark optimizations.

Of course, a level playing field is necessary in an industry where benchmarks, for a small number of users, inform buying decisions, but we always recommend looking at the entire device — not just the speed of its cores — as a measure for purchase.

Amazon Fire HD 10 vs. iPad Air 2: Which is the better big tablet?

Is Amazon’s big tablet a worthy alternative to the might of the Apple iPad Air 2?

Both Amazon’s and Apple’s tablets have their own content ecosystems to go along with their hardware, so in some ways are very similar. The biggest difference, of course, is Amazon’s Fire HD 10 uses Android, while Apple remains the default choice for the casual consumer considering a tablet, since iOS has the App Store.

The question is, if you’re looking for a big tablet, is the Amazon Fire HD 10 a good buy, or does it fall short compared to the stalwart iPad Air 2?

Hardware

The Fire HD 10 starts at $229 in 16GB configuration with special offers and is available in white or black plastic or a silver aluminum finish. Other options include 32GB or 64GB of storage, and for an extra $15 you can take away the money-saving lock screen ads.

The iPad Air 2 starts at $399 in its base 32GB WiFi configuration, with all metal finishes and available in silver, gold or Space Gray. Not only does Apple offer a higher base storage but there’s a 128GB model available for $499. Both sizes of the iPad also offer an optional cellular version for an additional $120.

Storage is a more important consideration when buying an iPad versus buying a Fire tablet. While Apple’s tablet is sealed off and you get what you get, Amazon throws a microSD card slot on the Fire for expandable storage. So you can get away with buying a cheaper model and purchasing a low-cost memory card for your apps, games and media content if you wish.

Amazon has the price edge, but when it comes to all-round specs, there’s no denying Apple’s more expensive iPad Air 2has the Fire HD 10 on the ropes.

Amazon has the edge there, but when it comes to all-round specs, there’s no denying Apple’s more expensive iPad Air 2has the Fire HD 10 on the proverbial ropes.

The iPad Air 2 has a gorgeous 2048 x 1536 9.7-inch Retina Display, which is also great to use in portrait thanks to its 4:3 aspect ratio. By comparison, the Fire HD 10 has a rather lowly sounding 1280 x 800 resolution 10.1-inch display in a more common (for Android at least) 16:9 widescreen aspect ratio. This makes it perhaps better for watching videos, but more awkward to use in portrait mode. It’s disappointing, too, that it’s not even a Full HD display in a tablet that costs over $200.

It doesn’t stop at the display, either. Down to the processor, RAM, even the cameras, the iPad Air 2 is a higher-end, more sophisticated tablet. But while Apple wins on the hardware, there’s always more to it than that — otherwise, everyone would always buy an iPad.

Software

At this point in time it’s not worth debating Android vs iOS. If you have a strong preference towards either you’ve probably already made up your mind. The key thing to point out here is that while the Fire HD 10 runs Android, it’s not the same build you’d find on your phone or Samsung tablet. There’s no Google here, only Amazon and its customized Fire OS.

Fire OS is better now than it has ever been, but it’s still a big storefront for Amazon’s products and services. If you use Amazon stuff, that’s probably why you’d even consider a Fire tablet and you’ll probably be OK with it. Fire OS is easy to navigate and isn’t a huge departure from the principles of ‘regular’ Android. But because there’s no Google, there’s no Play Store, which means using the Amazon Appstore for your apps and games.

Amazon lets you add more storage. Apple does not.

That’s not as bad a thing as it used to be, but there are shortcomings in the availability of some apps and how often they’re updated over their Play Store compatriots. By contrast, the iOS App Store has pretty much everything you could want, including Google and Amazon services.

The Amazon Prime Video and Kindle experience on the Fire HD 10 is still best, though, even if you can get it on the iPad. With being able to save offline video from Prime to a microSD card on the Fire HD 10, you’ve got a big advantage over the limited storage on the iPad, unless you stump for the 128GB option.

What’s also better on the Fire HD 10 is the specialized mode for your kids. With Freetime (or Kids Unlimited depending where you are) for a small fee you can create a locked, curated area of the Fire HD 10 for your little ones. It gives them targeted content to enjoy without you worrying about your credit card being used to buy a laptop on Amazon.

Voice Assistants

Finally, we have the voice assistants: Amazon’s Alexa and Apple’s Siri. The latter has been around much longer but the former is arguably more refined and more useful. Alexa isn’t just confined to the Fire tablets. You’ll also find it on the Amazon Echo, the Fire TV and even third-party products now such as the Huawei Mate 9 and the Android-based CoWatch. It’s an AI assistant that can play you music, tell you the weather, control your smartphone, hail you an Uber and so much more.

Siri has long felt underwhelming and been the butt of many a joke over the years. Apple hasn’t done nearly as much with Siri as Amazon has with Alexa in a much shorter time, and there’s no surprises which one would get our vote.

The conclusion here is something of an odd one. The iPad Air 2 is a better tablet if you treat it on face value. It’s nicer, more powerful hardware with all the apps you’ll ever want, a gorgeous screen and access to all the Amazon content, too. But that doesn’t necessarily mean you should buy one.

For once, the better tablet isn’t necessarily the one to buy

For starters, it’s $170 more expensive than the cheapest Fire HD 10, and that’s a lot of money. It’s almost a second Fire HD 10. It’s a significant saving, with compromises which aren’t enough to recommend folks stay away from it. The display is disappointing, but not horrible, you’ve got the space for tons of storage and if you’re a heavy media consumer or Amazon user, it’s a no-brainer.

The iPad Air 2 excels in areas that you might not even be bothered about using a tablet for. It’ll be better for playing high-end graphically intense games and many folks use them for light work. But is that enough to make you spend that $170 more? For once, the technically better tablet isn’t really the one to buy.

Magnetic fields could explain an ‘erratic’ neutron star

Scientists think they’ve discovered why an unusual star system is emitting “sudden, erratic and extremely intense” bursts of X-rays. Using three different space telescopes, the team set out to investigate “Rapid Burster,” a binary system first discovered in the 1970s, in 2015. It contains a small star and a “neutron star,” the term given to collapsed cores of formerly giant stars. Normally, this setup would produce “type-I” bursts, as the dense neutron star strips the gas of its younger neighbor. The Rapid Burster does this too, but curiously it also exhibits rarer, high energy “type-II” blasts.

Following some close examination, scientists believe the neutron star’s magnetic field is to blame. It spins so fast that it creates an inner edge to the gaseous disc collected from its companion star. The best way to think of it is like a merry-go-round — the field spins at such a velocity that hardly anyone can get on. As the gas accumulates at the edge, however, it gradually spins faster and is able to make the jump. That build up, the team says, is what causes the seemingly erratic and powerful type-II bursts.

“The Rapid Burster is the archetypal system to investigate type-II bursts — it’s where they were first observed and the only source that shows both type-I and type-II bursts,” Jakob van den Eijnden, a PhD student at the Anton Pannekoek Institute for Astronomy in Amsterdam explains. Indeed, type-II bursts have only been discovered in one other place: Bursting Pulsar, another binary system uncovered in the 1990s. The far-flung location, as far as scientists can tell, exhibits type-II bursts exclusively, however. That makes the Rapid Burster unique, and a constant curiosity, one that will no doubt attract further examination in the future.

GoPro’s troubled Karma drone is back on sale today

Surprise! GoPro’s Karma drone is back on sale. GoPro recalled Karma in the run-up to the holidays last year due to instances where drones were losing power mid-flight (not cool, obviously). In early January, the company cryptically “announced” that it would give details on Karma’s return in early February.

Many speculated that probably meant we’d see its return later that month, or early spring. Instead, the news, delivered this morning, is simply that it’s returning to “select” retailers (no word on which), and GoPro’s online store today. International buyers will have to wait just a little longer, with the company only committing to “spring” for non-US customers. The timing isn’t that surprising, as GoPro is also announcing its holiday period financial results to shareholders tomorrow.

If you were hoping Karma might get a little upgrade, or a price-cut upon its return to curry favor with potential and previous customers alike, sadly you were wrong. Introducing new functionality at the same time as trying to isolate and fix a problem is probably not wise, any way. Instead, GoPro hunkered down and clocked in thousands of hours of test flights to make sure its fix (a change in the battery clasp mechanism) had done the job.

We also imagine GoPro came under pressure to get the Karma show back on the road/up in the air, so new software features would likely have introduced unacceptable delay. Though, there is the promise of updates later down the line. As for discounts, GoPro already gave early buyers a free Hero 5 camera for the inconvenience of returning their drone.

A few days ago, GoPro added a ($399) “Karma core” item to its online store, which only includes the body, arms, and landing gear (no gimbal or controller or backpack). Today, GoPro’s also adding a “Flight Kit” which comes with everything but the Karma Grip and the gimbal (for those that bought them separately) for $599.

It’s fair to say that it’s been a bumpy ride for GoPro with Karma. When it was first released, it was generally positively received by mainstream technology sites (Engadget included). The hardcore drone-enthusiasts were, well, less enthusiastic. Especially once DJI released its smaller, more featured Mavic Pro causing many industry pundits and forum users to vocally denounce GoPro’s debut product in this space. IN particular this one scathing review, from a vlogger later spotted working for DJI at CES.

When I spoke with GoPro CEO Nick Woodman last month, he was eager to point out that the hardcore drone crowd have plenty of options they may prefer. The message being that Karma is, essentially, a set of tools for people that want to get the most out of their GoPros. Let’s hope that that’s enough people to persuade the company to make another one, as right now DJI’s pretty much the only big player in the consumer camera-drone game, and that’s not good for anyone but DJI.

MIT demos smartwatch app that detects emotions

A conversation is never just about the words we speak, it’s about our tone, volume, body language, gaze and everything in between. But the signals that we send out can sometimes be misinterpreted, or ignored, by people who struggle to understand non-verbal communication. That’s what prompted researchers at MIT to develop software that could take the ambiguity out of what people say, and what they do.

Researchers Tuka AlHanai andMohammad Mahdi Ghassemi built an algorithm that can analyze speech and tone. This data is crunched to work out what emotion a person is roughly feeling for every five second block of conversation. In one example, a person is recalling a memory of their first day in school, and the algorithm can identify the moment the tone shifts from positive, through neutral, down to negative.

The researchers used an iPhone 5S to record the audio part of the conversations, but made each test subject wear Samsung’s Simband. That’s the company’s developer-only wearable platform that runs Tizen and has space for various additional sensors. It’s not the most elegant of implementations, but the pair have built the system with an eye on incorporating it inside a wearable device with no outside help.

Right now, the implementation is very rough around the edges, and basic to the point where it couldn’t be used more widely. But, the pair believe that it could be the first step on the road to building a social coach for people with an anxiety disorder or conditions like autism. It’s early days, but if there was a device that meant an end to awkward conversations, it would probably be quite popular.

Spaceflight changes the shape of the human brain

The human brain reshapes itself during spaceflight, according to a study by a team of scientists from the University of Michigan. They came to that conclusion after comparing the structural MRIs of 12 astronauts who only spent a couple of weeks as ISS crew members against 14 who spent six months aboard the space station. Apparently, they saw both an increase and a decrease in gray matter in different parts of the brain, and those changes are more pronounced in the subjects who spent the most time in orbit. In short the more time you spend in space, the more gray matter gets displaced.

According to lead investigator Rachael Seidler:

“We found large regions of gray matter volume decreases, which could be related to redistribution of cerebrospinal fluid in space. Gravity is not available to pull fluids down in the body, resulting in so-called puffy face in space. This may result in a shift of brain position or compression.”

The team also observed an increase in gray matter volume in the parts of the brain that control leg movement and the parts that process sensory information in the lower extremity. This could be the result of the human brain learning how to move in microgravity. The researchers think that the change became very noticeable despite the relatively short amount of time the astronauts spent in orbit because their brains learned 24/7 aboard the ISS.

They still haven’t figured out the exact nature of the changes, though. When they do, their findings could be useful for the study of hydrocephalus and other conditions. The team believes this is the first study of the structural changes of the human brain during spaceflight. However, this is far from the only one that looked into the effects of long-duration missions on the human body. We have to make sure spacefarers can endure months or years outside Earth before we send them off to explore new worlds.

OnePlus 3T caught cheating on benchmarks

No, the days of smartphone makers cheating on benchmarks aren’t over yet. XDA has discovered that the OnePlus 3T artificially boosts processor clock speeds when running certain benchmark apps, keeping its CPU cores running at higher rates even when there was virtually no processor workload. This has apparently been a staple of HydrogenOS (OnePlus’ interface for the Chinese market) for awhile, but only showed up in OxygenOS (the software for other parts of the world) in community builds ahead of the Android 7.0 Nougat upgrade.

The good news: the 3T won’t be playing fast and loose with numbers for much longer. In a statement, OnePlus says that it will stop ramping up the processor for benchmarks in “upcoming” OxygenOS releases for both the 3 and 3T. The company claims that this was part of a broader effort to provide a “better user experience” in demanding apps (particularly games), although that doesn’t really pass muster — there was no reason to be hiking speeds in benchmarks. You can read the full statement below.

OnePlus certainly isn’t alone in this behavior, as XDA caught the Meizu Pro 6 Plus cheating at the same time. That doesn’t justify rigging tests, however, and it suggests that benchmark makers and testers alike will have to remain extra-vigilant if they want to keep companies honest. It’s also a reminder to test phones in real-world circumstances whenever possible — even when benchmarks are accurate, they can only tell you so much about your day-to-day experience.

“In order to give users a better user experience in resource intensive apps and games, especially graphically intensive ones, we implemented certain mechanisms in the community and Nougat builds to trigger the processor to run more aggressively. The trigger process for benchmarking apps will not be present in upcoming OxygenOS builds on the OnePlus 3 and OnePlus 3T.’”

The best baby monitor is a simple night-vision camera

As a tech reporter, I’ve been pitched a whole host of smart baby monitors recently. That’s partly because I work here, and also because I have easy access to an infant with whom I can test out such gadgets. Nanit, Cloudtot, Neebo, Owlet and Knit (to name a few) all claim that they can soothe the brows of novice parents like myself. But the more time I’ve spent with Project Nursery’s 5-inch HD Video Baby Monitor, the less I want the extra bells and whistles. They’re nice, for sure, but they aren’t essential to the fairly simple practice of parenting.

I hadn’t bothered to buy a baby monitor when my girl was born because my wife and I knew we wouldn’t need one for months. In those early days, you can’t let your kid out of your sight for a moment; indeed, we still sleep with her in a cot at the foot of the bed. When it came time to finally get a monitor, I opted for a smart-ish one because, you know, I have a reputation to maintain.

Project Nursery’s set comes with a micro-USB-powered night-vision camera that generates its own 2.4GHz wireless signal. Then there’s the so-called Parent Unit, a boxy 5-inch display that looks more like a fancy home cinema remote than a baby gadget. In addition, the package comes with a “Mini Monitor,” a 1.5-inch cube that can be worn on the wrist for more mobile monitoring.

The Parent Unit lets you control the camera, letting you reposition its angle like you’re a security guard in a surveillance state. In addition, you can speak through the device’s built-in microphone / speaker combination — again, like you’re an all-seeing guard. Unlike in a totalitarian regime, however, you can also play pre-recorded lullabies from the device to send your kid to sleep.

The experience of using it is actually pretty lovely. Setup took just five minutes and most of that was pulling the plastic packaging off. Being able to watch your child while you do the dishes, sterilize bottles or — gasp — stare at the TV is extremely useful. Still, I’ve found that the ability to watch her is pretty much all I need or want from my baby monitor; I know when she begins stirring and can quickly race upstairs to soothe her.

The device is not without its faults. For starters, the laughable notion that a cube standing an inch from your wrist is “wearable.” I mean, you can, but you’d certainly only do it when nobody else is watching — and I’m not admitting to that in front of all you. Then there’s the fact that the Parent Unit is rated for 16 hours of battery life, but I find myself reaching for the charger after a combined eight or nine hours over two or three days.

Much like Owlet, the camera’s base here has an obnoxious glowing light that can be distracting when you’re trying to sleep. And the speaker, when it’s replaying human voice, is sufficiently distorted and crackly that you’d probably wind up giving your kid more nightmares. Not to mention, as well, that the retail price for this device is $300, which is probably a little bit too much when you could roll your own solution for much less. Or buy the 4.3-inch version for $200, which will be a little easier on your wallet.

But, and I guess this is the point, the device does precisely what you want a baby monitor to do without too much friction. You plug it in, it sets itself up and boom, you can watch your kid so you don’t have to sit in the same room. I don’t need artificial intelligence to tell me how much sleep she’s getting or the ability to view her on my smartphone. A night-vision camera and a portable display are all you really need because being able to see when she starts rousing means you can offer comfort. And that is worth its weight in gold.

Apple Quietly Updates AirPods Firmware to Version 3.5.1

Apple today quietly put out a firmware update for the AirPods, bumping the Bluetooth headphones from version 3.3.1 to 3.5.1, as spotted by a user on Reddit. The update to AirPods is automatic for any AirPods in their Charging Case and connected to a nearby iOS device. After making sure the AirPods are connected, users can check their current firmware version by going to the Settings app on iPhone > General > About > AirPods.

It’s not clear what the 3.5.1 update covers due to its silent release and a lack of specific patch notes, but the AirPods have faced a number of complaints over the past few weeks that the new firmware version could potentially be addressing. Mainly, there have been a number of user complaints regarding battery drain issues with the AirPods and the Charging Case, as well as dropped Bluetooth connections when on phone calls on iPhone 6s and iPhone 6s Plus devices.

AirPods launched in December to largely positive reviews from users praising their ease of connectivity with iOS devices, thanks to the W1 chip, as well as their sound quality. Since the launch, the AirPods have been hard to come by both online and in Apple retail stores, with current shipping estimates on Apple.com sitting at the six week mark, arriving mid-March if users order today.

Fantastical 2 for OS Gains Stickers, Rich Notifications, and Haptic Feedback

Popular calendar apps Fantastical 2 for the iPhone and Fantastical 2 for the iPad are both being updated to version 2.8, adding support for many new features introduced in iOS 10.

Fantastical 2 now includes a set of stickers that can be used within the Messages app. The stickers feature an animated, smily calendar icon with useful sayings like “I’m on my way!” or “I’m running late!” so users can send quick messages to friends. There are also a set of emoji-based stickers for general usage.

Rich notifications are now included, so users can see additional details about upcoming events and reminders directly from the lock screen, and on the iPhone 7 and the iPhone 7 Plus, haptic feedback is supported.

“We’re really happy about iMessage stickers,” said Michael Simmons, Co-Founder of Flexibits. “They are a fun and friendly way to let someone know you’re running late or even propose a dinner date.”

With all of the iOS 10 features, both versions of Fantastical 2 now require users to be running the iOS 10 operating system. Other new features include improved support for Dynamic Type, improved reliability of the Apple Watch app, and other small fixes and performance improvements.

Fantastical 2 for the iPhone is available from the App Store for $4.99. [Direct Link]

Fantastical 2 for the iPad is available from the App Store for $9.99. [Direct Link]
