Samsung has been working on a foldable phone for seemingly forever, but the release of this fabled device keeps getting delayed (presumably because the entire concept doesn’t make a lot of sense).
Now, a new leak claims to show a cancelled, two-screened phone from Samsung, and it looks surprisingly boring.
The concept, leaked by Twitter user @MMDDJ_ and noticed by SlashLeaks, is basically a fat Samsung phone with a second screen on a hinge. Apparently, it was called Project V (model number SM-G929F) — we’ve heard of a similarly named foldable Samsung phone in 2016, so that’s presumably when this thing was designed.
By the look of it, we won’t shed a tear over the fact that this project got cancelled, as the phone doesn’t appear to be very useful, or chic, even by 2016 standards.
It’s worth noting that ZTE did launch a device very similar to this one in 2017 — and it still didn’t make much sense.
The rumors that Samsung is still working on a foldable phone (presumably with a flexible OLED screen) refuse to die, though, so we may still see some variant of it in the future.
South Korean wireless carrier SK Telink discovered an unsold shipment of the third-generation iPhone hidden away in a warehouse, local news service ETNews reports (h/t VentureBeat). Each one will be sold unlocked for the U.S. equivalent of roughly $40.
All of the devices are never sold, new-in-box products. Though given their age, SK Telink plans to open each one, test it, and — provided it works — repackage it. The iPhone 3GS arrived in South Korea for the first time in late 2009, and there’s no way to know if their rechargeable batteries still work without testing them first.
Just be clear before you pick one up, if that’s something you’re considering: In 2018, you’re going to get a very stripped down Apple experience using an iPhone 3GS. This third model in the line to be released was the last to sport a plastic shell; it also used a larger SIM card than iPhones currently do, and it sported the pre-Lightning Apple port.
It’s also capped in terms of performance. The iPhone 3GS is so named because of its support for the last-gen 3G cellular network. You can connect it to the internet via WiFi, but speeds will be noticeably slower than they are on more modern devices that support a 4G/LTE network.
The big advantage you get when you’re buying a six-year-old (or more) smartphone is a lower price. As VentureBeat points out, the $40 cost attached to these newly discovered iPhones is significantly below even Apple’s cheapest smartphone in South Korea, the iPhone SE, which retails there for roughly $450.
It’s also not clear what kind of warranty SK Telink plans to offer customers.
All that said, if you feel a sense of wonderment over technological artifacts like this and you happen to live in South Korea, these affordable new-old iPhones are worth a look.
Sure, the summer has just begun, but that means we’re inching closer to Apple announcing new iPhones in September.
Apple is widely expected to announce three new iPhones this fall. Along with a spec refresh for the iPhone X, all signs point to Apple announcing a larger 6.5-inch Plus-sized version and a 6.1-inch model that’ll likely be priced under $1,000.
Is this the beginning of the end of the $1,000 iPhone? Don’t count on it. As with most things, you’ll get what you pay for.
The key difference between the upcoming 6.1-inch iPhone and the iPhone X and 6.5-inch “iPhone X Plus” will be the display.
One of the reasons why the iPhone X is so pricey is because of the custom OLED display. The screen is designed by Apple and produced by Samsung. Unlike the Super AMOLED displays used in Samsung’s own Galaxy phones, the iPhone X’s OLED screen has a flexible design that enables it to fold backwards internally to stretch the screen edge-to-edge. The result is the iPhone X doesn’t have a “chin” below the screen like many Android phones.
Besides the design advantage, the OLED screen also produces deeper blacks, higher brightness, richer colors, and increased power efficiency.
These features are wonderful, but they’re also lost on many users. Despite the iPhone X being the best-selling iPhone since its release last November, many people are still reluctant to buy it because it’s too expensive.
Which is why Apple is expected to sell the 6.1-inch iPhone for under $1,000 — possibly starting it at about the same price as the current $700 iPhone 8 or $800 iPhone 8 Plus.
But in order to sell the new iPhone for less, Apple needs to reportedly cut some corners. Instead of an OLED screen, the 6.1-inch iPhone will probably have a regular LCD. It’ll probably still be a really good display — at least on par with the iPhone 8 and 8 Plus — but it won’t have any of the OLED benefits I mentioned earlier.
With a lower price, there’s greater potential the new iPhone will kickstart a new “super cycle” for iPhone sales as users who’ve hung onto their older devices are enticed to upgrade. Many analysts strongly believe Apple has requested suppliers ramp up more production for the LCD-based iPhone than the OLED models, according to the Wall Street Journal.
If true, the report suggests Apple is expecting more people to buy the LCD-based iPhone over the its more expensive OLED iPhone X and the yet-to-be-announced iPhone X Plus.
The display won’t be the only thing that differentiates the LCD iPhone from the other two, either. Though all three new iPhones are expected to look virtually identical from the front — they’ll all have a notch and edge-to-edge screens — the materials used to build them will probably be different.
The iPhone X and “X Plus” are expected to have a stainless steel frame and dual rear cameras. However, the 6.1-inch iPhone is rumored to have a less premium aluminum frame with single rear camera. The back is still said to be glass and will support wireless charging.
And, yeah, don’t count on the headphone jack coming back. Seriously, just give up on that idea. It’s never coming back.
I’ve made the case for why the $1,000 iPhone X is worth the money, but not everyone can afford it. We all want Face ID and Memoji is going to straight up crush it, but if only the elite can buy the a phone that has the features, Apple splits its customers into the haves and have-nots. It’s time to get everyone into the haves boat. A cheaper iPhone X seems to be the way to go.
Mobile World Congress is one of those events that make you realize the thin line between civilization and barbarism is the width of a single charging cable.
Anyone who’s attended MWC (or any massive trade show) is familiar with the creeping dread caused by watching your phone’s battery power seep away over the course of a very long workday. Tweet by tweet, photo by photo, text by text, the percentage points tick away, until you’re scrambling in your bag for a battery pack amid a tangle of chargers and cables or searching the packed halls and press lounges for a free plug point — an oasis in the desert.
Imagine you never had to seek out an outlet, carry a backup battery, or stuff an array of cables into your bag again; that all your devices were being charged continuously, no matter where you went. Someday you may not have to imagine it — because companies like Energous and Ossia are working to make it a reality.
Nikola Tesla first envisioned a wireless power transmission system in the early 1890s; he even attempted to build an experimental station, Wardenclyffe Tower, which he hoped would be the first in a worldwide wireless system. Today, phones, smartwatches, and other devices sometimes come with inductive charging coils, which let them charge wirelessly through resonant inductive coupling. But this method relies on direct contact between the device and a charging pad — hardly the untethered future Tesla imagined.
That’s where Energous and Ossia come in. Both focus on developing “true” wireless charging that works over the air (OTA) so you can power up at a distance. This is the wireless charging we were promised over a century ago. Could our dependence on cables or tethered charging solutions finally be coming to an end?
Why Today’s Wireless Charging Disappoints
Though wireless charging has been around for years, it had a big boost last year, when Apple announced that its new phones had the feature. Qi, used by most phones (including iPhones), and the lesser-known PMA are the two forms of wireless charging used by current consumer-oriented devices. Both standards require one or more induction coils in a charging pad to transmit power and another in the device that’s being charged.
There are some minor differences between the two standards, but they share the same limitations: the need for very close contact between the device and the charging pad, as well as proper alignment of the induction coils, for power to be transmitted.
The range can be slightly extended: The FCC Office of Engineering and Technology Laboratory Division recently approved an increase in distance of up to 20cm, potentially by using multiple charging coils. So far, though, no products currently utilize longer-range wireless charging for inductive charging coils.
Other potential problems with this type of wireless charging include heat buildup. “The circuitry in the wireless charger must be thoughtfully designed to prevent excess heat from building up in the charger and transferring to your smartphone,” said Jack Norton, director of electrical engineering at Belkin. “Excess heat can lead to lower life spans for the wireless charger [and] your phone’s battery.”
The primary reason that wireless charging is slower than using a fast charge–enabled power brick is that a device will reduce its charging speed to manage heat and prevent damage to sensitive components. “Managing heat is definitely one of the challenges in wirelessly transferring power beyond 10 watts,” said Charlie Quong, VP of product development and engineering for Zagg (Mophie).
Thermal dissipation can be managed in a variety of ways, including: passive airflow, which means putting holes or vents in strategic locations to transfer heat away from the device being charged; cooling fans; heat sinks made of metal or thermal glue; larger housing; specialized material; and more efficient component layouts. But even when you mitigate heat, inductive-charging speed for phones is limited. According to Pablo Valentin, global product manager at Belkin, “The fastest output realized in the market right now is 15W, both from charger side and phone side.”
That means a device such as the Samsung Galaxy S9+ ($839.99 at Samsung), which is fast charge–compatible, can juice up to 50 percent in 1 hour and 34 minutes. That’s not quite as fast as regular fast charging using an adapter (35 minutes to 50 percent), but it’s a big step toward making wireless charging fast and convenient.
For larger devices such as laptops, which have more surface area and ventilation options, wireless charging can go to 30W or more. But when it comes to phones, you’re still likely looking at a charging speed of 10W to 15W for most wireless charging pads, with most of them dropping down to slower wattages (5W) to prevent heat buildup. That’s quite a bit slower than a 27W Qualcomm Quick Charge 4.0+ power adapter or 29W USB-C Power Adapter for the iPhone X ($999.00 at Verizon Wireless), for example.
Another and perhaps more significant downside of inductive wireless charging involves the size of the charging coils. “There are different coil designs that can be implemented, depending on the application, but the size of the coil must be optimized and calibrated correctly for a wireless charging system to work properly,” said Quong.
Charging coils can be made to fit on small devices such as Bluetooth earbuds, but such coils are uncommon. According to Gary Gao, wireless charging leader for Anker, the most common coil design is 50mm in diameter as required by the Qi standard.
Finally, the biggest limitation of Qi wireless charging is the paucity of the kinds of devices on which it can be implemented. “Right now, if you look at wireless charging, you see it on your phone primarily, and a few other random devices like the smartwatch from Apple,” Energous President and CEO Stephen Rizzone said. “But it doesn’t really get beyond that, and part of that is because of the limitations of that technology.”
What Does This Look Like?
Though other companies are exploring this space, the Energous and Ossia wireless charging standards come closest to matching Nikola Tesla’s vision. The two technologies operate using different radio frequencies, but they both let you charge a device from a distance, transmitting power over the air without using cables or inductive charging coils.
Energous: The Energous wireless charging technology works with the company’s proprietary WattUp transmitter and receiver. It operates similarly to Wi-Fi by transmitting power in the 900MHz frequency to the receiver, which converts the RF signal into DC power.
Energous uses beamforming for the mid-field and far-field transmitters: a directional antenna array sends energy directly to the receiver. In the case of obstacles, it can reflect energy beams off walls and ceilings, although this results in some efficiency loss. The technology breaks down into three different types of wireless charging: near field, mid field, and far field, with varying ranges.
WattUp near-field charging requires a transmitter that can plug or be embedded into existing electronics — laptops, game consoles, tablets, and other devices. It’s certified under Part 18 of the FCC requirements: That means it can output up to 10W of power because of the closer proximity to the transmitter. Rizzone anticipates WattUp charging higher-drain devices, such as phones, while still being able to charge any other device with the same charging circuit.
The mid-field transmitter is certified under Part 18 of the FCC’s rules, so it can send large power outputs at a distance of 2 to 3 feet, with the standard use case being a desktop setup. Energous envisions it being designed into a desktop speaker and charging multiple devices placed around it. Far-field is the longest range currently possible: 15 feet. A typical use case would be a living room.
In each implementation of near-field, mid-field, and far-field charging, Rizzone imagines close integration with existing consumer products. “You’re not going to want to have a big router-type-looking thing,” he said. “Instead, you would primarily put that technology into the bezel of a television, [or] it could be a sound bar, it could be a few different things that are already in the room.”
In addition to charging at a distance, each transmitter would be supported by a software layer (app- or web portal-based) to allow power management of devices connected to the various WattUp transmitters. You’ll be able to control which devices are charged and to prevent your transmitter from charging your neighbors’ devices. The mid-field and far-field transmitters also allow you to set device priorities and rules for charging and authentication and to configure charging zones. The short-range transmitter is more traditional: You can’t set priorities or charging rules, but once you drop the device on the charging pad, you’re able to view its battery level and expected time to charge fully.
The transmitter “sees all the different Bluetooth devices that are within the room,” said Rizzone. “It identifies which ones are close enough to be charged and also identifies [whether] they’re authorized on the network, and then it actually monitors, with sensors, what the user’s typically doing.”
This type of software-based power management is vital, Rizzone said, because “under Part 15 rules, you can only send one watt of power out. That means that at a foot away, you’re going to get … one milliwatt or lower. So a very, very small amount.” (FCC Part 18 doesn’t limit the amount of power).
With the widespread adoption of WattUp transmitters, though (however far off that might be), you’d be able to go to a coffee shop and even travel without having to carry adapters or cables: Various transmitters in public and private spaces would top up your various devices as you need them and according to your usage patterns.
Ossia: Energous is focused on consumer-level wireless charging, but Ossia has a bigger scale in mind.
As with Energous, the company’s technology is similar to Wi-Fi and uses the 2.4GHz spectrum (it’s considering the 5.8GHz spectrum for the future) under its proprietary “Cota” standard. Ossia’s receiver sends a low-power beacon signal to the Cota Power Transmitter. The transmitter then directs power along the same pathway, with the receiver converting the RF signal to DC power. That allows Ossia’s transmitter to send power to multiple Cota-enabled devices simultaneously and to send power to objects in motion. It also effectively bypasses objects that are in the way, since the signal doesn’t pass through people, animals, or other organic matter.
The current implementation of Ossia’s technology is currently showcased by two prototype devices — the Cota Forever Battery and the Cota Tile. The Forever Battery is a AA or AAA battery that wirelessly receives power from a Cota Power Transmitter on the 2.4GHz band. The Cota Tile is a transmitter capable of delivering several watts of power to Cota-enabled devices close to it and milliwatts at a distance of 30 feet. It operates at a greater range than Energous’s far-field transmitter, but this requires the transmitter to be larger.
“We know that at a distance, signals drop off very quickly, and we don’t really get much power in a far field,” said Hatem Zeine, Ossia founder CTO. He explained that the company designs antennas and transmitters to be large enough to extend range of the near field.
Zeine was keen to point out that for consumers, the key to providing useful wireless power isn’t necessarily to transmit a high degree of power to one or two devices. “The idea is that power has to be continuous, no matter how fast you go,” he said. “This system [the Cota Tile] is running 2.4GHz with 20 watts coming out. At about a meter, we’re receiving over 6 watts of power, and at two meters we’re talking about a few watts, 2 to 3 watts, and then at the end of the room we’re talking about 1 watt. So now, suddenly … every cubic inch of this room has power.”
In other words, while a Cota Tile may take a long time to power a phone except at close range, it’s more than capable of keeping every device in a living room topped up — from game controllers to security cameras.
The method for connecting devices to the Cota Tile is similar to traditional Bluetooth or Wi-Fi pairing. The setup allows you to control which devices get charged and manage them as they charge. “If it’s an intelligent device like this [Zeine indicates a phone], then you can basically go into the system here and say, ‘Add me to the power network,’ and it will talk to [the Cota Tile],” said Zeine.
The Cota Cloud software is able to define the priority of devices that get power and show the basic power usage of the device. When using the Cota Tile on a large scale, the administrator can set up and manage users. With prioritized charging, the Cota Tile first charges devices with lower battery levels; the Cota receiver communicates with the transmitter about how much power it needs. When there are no devices within range that need to be charged, the Cota Tile goes into sleep mode, so it’s not wasting energy or transmitting power to devices that are already topped up.
The Cota Tile is able to power a variety of devices in a room because it doesn’t have to operate on line of sight. A pair of Cota Tiles are twice as efficient and emit four times the power of a singla Cota Tile. So in a warehouse, for example, numerous Cota Tiles can join together to power hundreds or thousands of compatible devices.
“It’s unique, because when you put two or maybe even four together, and you can envision it in the ceiling, that amount of power can power a coffee shop,” said Zeine. “It’s a legitimate deployment commercially, where we could power multiple smartphones at the same time. … The other unique thing about having multiple tiles is they don’t have to be right next to each other. You can space them apart and therefore create a [continuous] power situation.” Like, say, walking along a corridor in an airport.
Since Ossia’s technology uses the same 2.4GHz band as Wi-Fi does, there’s little additional hardware needed to enable existing devices to work with the Cota Tile. “The goal is ultimately, the electronics … will be just like Wi-Fi, integrated into the device,” said Ossia CEO Mario Obeidat.
An IoT Revolution
The ability of the WattUp far-field transmitter and the Cota Tile to transmit data along with power makes them particularly compelling for the Internet of Things. “There’s no way you can get to a trillion IoT devices without wireless power,” said Jennifer Grenz, Ossia’s vice president of marketing, in a company blog post. “Wireless power is going to go hand-in-hand with the evolution of this entire market.”
The best example of this is Ossia’s Cota Forever Battery. It can be placed in smoke alarms, sparing you from charging them and also allowing for the transfer of data by giving you the Cota Cloud: cloud-based software that allows for power management of various devices.
“Let’s say your smoke detector in the kitchen goes off,” said Zeine. “The battery will notice that the smoke detector has changed its power-draw pattern and knows that this new pattern is actually the alarm going off. It sends a message to your phone; the Cota Cloud will tell you that, ‘Hey, your smoke detector is going off.’ This makes dumb devices smart. It brings them to the internet age.”
With both Energous and Ossia, the software layer is a key component of what makes them so game-changing, since they allow for intelligent power management. We all have devices that need charging, and when we charge them is up to us. We might charge a phone every day, a wearable every few days, a game controller whenever we use it. With wireless power, the software will make that choice for you based on your usage patterns, lifestyle, and even the time of the day.
Essentially, both the WattUp transmitters and Cota Tile take the burden from the user in deciding what device to charge and when, and take it on themselves. It’s as close to a seamless, cable-free existence as you can get.
Cutting One Cord At a Time
In practical terms, this technology is still a few years from implementation for both consumers and enterprises, but potential use cases are already apparent. Both technologies will allow you to effectively cut the cord at home. Phones won’t have to be plugged in. Game controllers will charge according to usage. Smoke detectors will never need their batteries changed.
Assuming widespread implementation in public spaces such as coffee shops and office buildings, the endless scramble for chargers, cables, and portable batteries could become a thing of the past. “In the future, you would go into a coffee shop. If it has the Cota logo, and you know your phone has Cota, that means you’ll get power when you’re in the coffee shop,” said Obeidat. “That’s the kind of standard that we’re creating.”
But the biggest impact is likely to be felt with low-power-consumption devices that need to be charged (or their batteries changed) infrequently. Rizzone cited the father of Gordon Bell, Energous VP of Marketing as an example of someone who would benefit considerably from Energous’ technology, though he doesn’t have many connected devices. “My colleague’s father wears hearing aids … What happens is, he’s got these little tiny batteries that are the size of a pomegranate seed, and he’s gotta put it in there and swap the battery out. It’s a nightmare for an older person.”
With a mid-field or far-field transmitter, hearing aids would be able to charge throughout the course of an entire day, according to the usage patterns of the individual user.
Of course, devices such as phones and Bluetooth headphones that are more frequently in need of power boosts are also going to see a shift to wireless charging, according to Rizzone: “A lot of devices that you’re currently plugging in and plugging in every single day, eventually, that little tiny tip of your micro USB port breaks. It wears out, or you jammed it in the wrong way, salt water gets in there, sweat, etc. That’s a failure part or a failure point for that product. So companies are trying to get rid of that.”
Radio Beams Everywhere: Are We Safe?
Energous’ longer-range transmission technology are certified under FCC Part 18 and Part 15 while Ossia has passed key tests for FCC approval of the Cota Transmitter, and approval is expected shortly. These rules impose RF exposure requirements and limit power transfer levels. RF exposure must be measured for users and bystanders under different wireless configurations. As a general rule, higher RF power is required to operate at a lower frequency.
In the electric vehicle industry, wireless charging has already been widely implemented and can indicate the kind of requirements we might see for electronics devices. According to an article by Joe Bablo, Ken Boyce, and Hai Jiang at Underwriters Laboratory, aside from the normal safety concerns that apply to any electrical transmission (fire, shock), the wireless charging system has to show it can operate in hazardous conditions and detect and shut down when an organic object enters, among other requirements.
Since the higher power Energous and Ossia technologies use the same radio frequencies as Wi-Fi, one would hope that there are no health impacts — but there are surprisingly few scientific answers to this question. The Nation has reported that the wireless industry has tried to limit the amount of research that can be done into the impact of wireless radiation on public health: “Lack of definitive proof that a technology is harmful does not mean the technology is safe, yet the wireless industry has succeeded in selling this logical fallacy to the world. In truth, the safety of wireless technology has been an unsettled question since the industry’s earliest days,” wrote authors Mark Hertsgaard and Mark Dowie. “The upshot is that, over the past 30 years, billions of people around the world have been subjected to a massive public-health experiment: Use a cell phone today, find out later if it causes cancer or genetic damage.”
According to Ossia, though, Cota technology is safe for people and pets and doesn’t interfere with Wi-Fi or face the overheating issues of Qi wireless charging. “2.4GHz and above don’t heat metal themselves; they reflect off the metal” Obeidat said.
Energous claims the same. “We’re not blasting energy all over,” pointed out Rizzone. “We’re planting a small, unique pocket of energy just around the device, and it transmits [to] that device.”
With FCC certification and no evidence to the contrary, the wireless transmission technologies should be no more dangerous or detrimental than Wi-Fi or any other RF spectrum we’re exposed to daily. Perhaps not the most comforting answer, but the only one readily available.
Our Wireless Future
Energous partners with Dialog Semiconductors, a large electronics manufacturer, to produce their transmitters and receivers while Ossia partners with Motherson and Molex, and there have long been rumors about Energous technology ending up in a future Apple product. Neither company manufactures its own hardware, nor do they create consumer products themselves.
Energous is primarily a licensing company, and its products are partner-based. Myant’s Skiin fitness- and health-tracking clothes, expected to ship this summer, are the first WattUp-enabled products. And neither Ossia’s Cota Forever Battery nor the sizable Cota Tile can be purchased. The company is working on getting the Tile into a smaller, more efficient form-factor.
“The future system that we’re working on will achieve the 10 meters and 20 meters,” Zeine said. “We’re focused at scales where people want to use this, so if they want to put this in the ceiling at Mobile World Congress, you could design a system that could cover 80 or 100 meters. If it’s for a home, you don’t need a system that’s that big.”
The first place you might see the larger Tile is in your local Walmart. In this case, you’d have several Cota Tiles providing power to thousands of low-power RFID tags. And the tags, which could show prices, discounts, and bar codes, could all be managed by software. It’s not the most exciting implementation, but it’s the one most likely to happen soonest.
Ultimately, wireless charging technology needs a few more years, a few more product announcements and certifications, and some experimentation by large retailers. So don’t throw out your cables and chargers just yet. But the widespread adoption of Qi inductive charging on phones and wearables is strong evidence that both manufacturers and consumers are eager to untether.
Anker’s Gao takes a cautiously optimistic view. In one or two years, he said, we should see more and more phones that can charge wirelessly, and he expects that wireless-charging efficiency will have reached the level of wired charging. Gao also said he hopes that in as soon as three to four years, we’ll have a “true position-free technology,” likely debuting on a wearable device.
Wireless power has always seemed like a work in progress. From Nikola Tesla till now, the promise has always been “the wireless power revolution is coming,” yet it never seems to arrive. It remains to be seen if Energous and Ossia can flip the script.
But there’s a reason wireless power is an idea that refuses to die. It promises freedom from arranging our lives around all the many power-hungry devices we’ve accumulated, each one acting as a tether that limits our movement. And that promise is worth waiting for.
With the release of iOS 12, Apple is poised to add a feature that Android users already know well: Spam reporting.
It appears that the feature won’t be baked in to run automatically at the system level, as it does on Google OS phones. Apple’s developer website shares the details on “SMS and call spam reporting,” which is described as an app extension that users will have the option of turning on or off.
“To report SMS messages and calls, the user must enable an Unwanted Communication extension in the Settings app,” the posting reads (h/t 9to5mac). “They can only enable one Unwanted Communication extension at a time.”
The website goes on to explain that users will be able to swipe left on individual items from their “Recents” list or in their Messages transcript. From there, they simply select the “Report” option and reporting feature handles things from there.
Blocked numbers are also automatically added to the device’s Blocked Contacts list.
What’s less clear is if this feature will be baked into an iPhone’s Apple-made phone app. It seems reasonable to assume that it would be, but given that this info comes from a third-party developer-facing info resource, there’s nothing about Apple’s own plans for utilizing the new feature.
On Android devices — or at least, on my own Pixel XL — the whole screen turns red when a suspicious call comes in, with the caller ID noting it’s a suspected spam call. Users have the option of swiping down then and there to report the number and add it to the device’s block list.
