Samsung smartphones will end up with a “maintenance mode” for your data protection when you have them repaired

Samsung rolls out One UI 5 ‘Maintenance Mode’ to keep your data safe during repair (9to5google.com)

My Comments

For a long time, most of the good cars came with a “valet key” arrangement of some sort. This especially benefited sedans (saloons), coupes and similar cars that had a lockable trunk (boot), but also benefited any car that had a lockable glove box.

Here, the car would come with one key that can only open the doors and start the engine but can’t open the boot or glove box. You could still open the boot or glove box with a separate dedicated key or another key that can open everything. This was about allowing you to had over your car to a mechanic’s, a valet-operated car park or a similar facility knowing that the staff at the facility can’t steal valuables from the glove box or boot.

Samsung is introducing the “Maintenance Mode” as part of its One UI 5 / Android 13 update for their recent Android smartphones. Here, it is to achieve this same goal by locking your personal data in a separate account not available to technicians who repair or service your phone. These technicians then have access to an account specifically created for testing and repairing the phone.

.. just like cars such as this Jaguar XJ6 did to limit access to the boot (trunk) and glove box when the vehicles were repaired or at valet parking

As well, they can install utility software on your phone as part of the maintenance work but once you log in to your phone again with your normal account, this software is removed. A question that can come up here is what happens if the repair requires the installation of software updates or patches, perhaps to provide driver support for replacement hardware and this has to operate with your own normal account.

Samsung are initially offering this to selected Galaxy phones sold within the USA as part of a beta-test for One UI 5 but are wanting to roll this out across the world through 2023.

Most of us would find this of benefit as we use our smartphones as the digital equivalent of our wallets, photo albums and keyrings. The well-founded fear we have with this is technicians taking advantage of our personal data especially if they see value in it for them.

I would see the “Maintenance Mode” feature being of interest to computing-device vendors and operating-system developers as something to add as a significant feature for an operating system. Here it may be offered during a major feature update cycle for the operating system or as part of a security package.

Such a feature could give all of us peace of mind when we relinquish a smartphone, tablet or laptop computer to technicians that we don’t know for repair.

Apple to lead the way with having smart lock and digital key management as part of a smartphone’s operating system.

Apple to add digital key sharing to iOS • NFCW

My Comments

Apple is the first mobile-operating-system developer to integrate the management of digital keys for buildings or cars within its iOS operating system. This includes the ability to share keys to others or revoke shared keys within your iPhone’s user experience.

It is because of an increasing number of security solutions for buildings, vehicles and the like that use your smartphone as a virtual keyring for digital keys.

Previously, what happened with digital keys was that they were dependent on apps specific to a vendor, hotel or similar smart-lock platform and you had to work these keys from that app’s user interface.

This could lead to confusion about apps that you need to use and can get very messy when you have multiple places to think of and you aren’t sure which platform they are associated with. It can also lead to screen clutter associated with the apps and you may find that they take up too much internal storage space especially if you are responsible for many places.

The approach now is to implement the digital wallet functionality offered by Apple Wallet and is part of iOS. As well, you use what the operating system offers to share out keys or revoke shared keys. That means you can use first-party messaging software like Apple iMessage or Apple Mail to share the keys; or you could use third-party messaging software like Signal, WhatsApp or Outlook Mail to share these keys.

Most likely this will be facilitated with the “share / take-further” function offered as part of the operating system, represented in iOS with a square and triangle symbol.

The problem with this functionality is whether there is the ability to limit the shared key’s functionality when you share it out. That is to limit the number of times one can use the key or the time period they can use it for, or even to limit the doors or cars that the particular digital key can open. In some cases, it may also be about implementing multi-factor authentication for these keys.

hen there is the question about what kind of interface that this Apple Wallet key-management ability will support. That is whether to use NFC “touch-and-go” operation, Bluetooth LE wireless-link or similar techniques to link with the door lock or car.

The other issue that will come about is whether Google will integrated this kind of digital key management within Android, whether as part of the digital wallets available as apps for that platform or simply within the operating system. Also it can be about whether regular computers that run desktop operating systems could have this kind of digital key management built in to their operating systems, which can be of benefit for people who manage buildings or vehicle fleets.

It can also include allowing apps and Websites to add or remove digital keys to the smartphone wallet. This will be seen as important for corporate, hotel and delivery use cases where interaction with smart locks is part of a transaction, such as registering the delivery / collection of goods or as part of a time and attendance requirement for home care and allied workers.

What this will be essentially about is to provide a one-stop shop for managing digital keys for locations or vehicles you are responsible for using your smartphone.

Qualcomm Announces First 5G Snapdragon 6-Series Mobile Platform (Press Release)

My Comments

5G mobile broadband technology will be coming to an affordable smartphone near you thanks to a new chipset that Qualcomm has now launched.

This chipset, known as the Qualcomm Snapdragon 690 chipset doesn’t just have a 5G modem for this class of product but also has processing power to handle some high-end tasks like 192 megapixel high-resolution photography or 4G HDR videography. There will also be support for Wi-Fi 6 (802.11ax) and Bluetooth 5.1 technology along with support for improved artificial-intelligence / machine-learning. It is although Qualcomm haven’t built mmWave support in to the 5G mobile broadband modem.

The silicon is being rolled out at the moment and will have a low bill-of-materials price compared to premium or midrange chipsets that Qualcomm offers. This will mean that a finished Android smartphone product would be expected to retail between USD$300-USD$500 before any telco subsidies. This is compared to the Apple iPhone SE which is a4G only product going for USD$400.

Phones based on this chipset will typically be manufactured by the likes of LG, Motorola, HMD Global (Nokia), Sharp, TCL (Alcatel) and the like. This will include various original-equipment-manufacturers who specialise in selling products under a private-label agreement with the distributor, retailer or telco.

The coronavirus plague, with the various event and business shutdowns associated with it, has  thrown a spanner in the works regarding bringing 5G mobile broadband in to the mainstream. As well there hasn’t been much market interest in newer smartphone technology and there would be a strong market for affordable smartphones thanks to people concerned about how much they spend, forced by the COVID-19-driven financial downturn.

But this chipset may also be about allowing manufacturers to take less of a gamble when it comes to creating a smartphone or tablet product that embodies a unique form of innovation or answers a particular market’s needs. An example that could come to mind would be a smartphone that has its radio circuitry optimised for long-range reception and pitched for rural and remote areas. Similarly, LG could pull it off again with a smartphone that has a DAB+ digital-radio tuner that would have a greater zone of relevance thanks to more European countries running DAB+ digital radio full time.

What is being highlighted here is that Qualcomm is making it feasible to provide 5G mobile broadband technology at a price affordable for the masses.

Sony holds 40th anniversary event for iconic Walkman music player | Japan Today

From the horse’s mouth

Sony

Walkman 40th Anniversary video – Click or tap to play

My Comments

Since the middle of 1979, there came a new way of listening to our favourite music while on the move.

This was brought about by Sony where its founder and CEO wanted a way to listen to music held on cassette tape through a highly-compact stereo cassette player that is connected to a pair of headphones. The production device that came about whose model number was TPS-L2 was based on one of Sony’s best handheld notetaker-grade cassette recorders of the time but played music in stereo through a set of headphones. In some markets it was known as the “Stowaway” or the “Soundabout” but Sony changed the product class’s name to “Walkman”.

This tape player opened up a product class based around a highly-portable stereo cassette player or radio that worked with a pair of lightweight headphones. As more of these devices came on the market, there was a huge rush to improve on their design for portability, sound quality, functionality, and affordability and they became the thing to have during the 1980s. A classic example of this was the Sony Walkman II (WM-2) which was about the size of two cassettes in their cases placed back to back.

Using these devices underscored the idea of a “personal soundtrack” that you enjoyed while you were on the move, whether it was your favourite broadcaster or one of your favourite tapes as you shut out what you didn’t want to hear. Most of these units were so lightweight that you could end up walking, jogging or running for a significant distance without them weighing you down, with this idea encouraging an increase in an interest towards physical exercise. On the other hand, travellers or those of us who had to go to hospital would take a Walkman and a collection of tapes with us to while away the time.

Today’s headsets like this JBL headset replace the headphones associated with the Walkmans

This is while you were able to hear your taped music in a manner where tape or playback faults could show up clearly. It encouraged the record labels to improve the quality of their pre-recorded “musicassette” offering with this manifesting in high-grade tape and higher-quality mass-duplication techniques for the cassettes. Examples of these include EMI’s XDR and CBS SuperSound cassettes.

Schools and parents worried about this device because it was a way for teenagers to shut out what they didn’t want to hear i.e. the lesson material or what the parents wanted them to do, then substitute it with the music that the kid preferred to listen to like the New Wave sounds of the era. As well, it brought about the expression of one being “wired for sound” when they continually used a Walkman device to listen to music, something highlighted in that 1980s Cliff Richard song “Wired For Sound” (Spotify).

With the CD came along the Discman which was a highly-portable CD player intended to he used as a Walkman but for a digital media source. There was also the DCC and MiniDisc Walkman products that used their own media kind. But these led towards file-based audio in the form of MP3 players like the Creative Nomad and Apple iPod family.

The smartphone is today’s equivalent of that Walkman

Eventually the role of the Walkman became part of the smartphone’s function set thanks to the Apple iPhone and some of the Symbian-based Nokia feature phones. You would be able to connect a headset to these phones which would be loaded with file-based audio content whether through tethered syncing with a companion app or through loading a memory card with these files. This is while it could be a navigation device, a communications device, a personal library or handheld games machine amongst many other things.

Along with this, the quality of lightweight easy-to-wear headphones improved over the years with factors like improved bass response. The different types of headphones came about such as active-noise-cancelling headphones and Bluetooth wireless headphones that removed the factor that destroyed many a set of Walkman headphones – broken wires. The headphones ended up being full-on headsets that allowed you to listen to music or make a phone conversation with the same device.

Over the past 40 years, the Walkman underscored the idea of the personal private soundtrack that you can enjoy anywhere using a small battery-operated music-playing device with a set of headphones.

Most iPads and iPhones updated to iOS 11.2 now safe from the KRACK exploit

Apple fills the KRACK on iPhones – at last | Naked Security

Previous Coverage

KRACK WPA2 Wi-Fi vulnerability–what is affected

My Comments

There has been intense computing-press coverage regarding the KRACK WPA2 exploit against otherwise-secure Wi-Fi wireless network segments. As my previous coverage highlighted, most of the major regular-computer and mobile operating systems were updated to rectify the vulnerability associated with this exploit.

Check the Settings App on your iPhone for the update

But, as I called out in the article, the iOS 11.1 update that Apple rolled out for their iPhones and iPads only remediated the vulnerability on certain newer devices. Here, it was ignoring a larger installed base of iPhones, iPads and iPod Touches by not providing the remediation for devices earlier than the iPhone 7 or the iPad Pro 9.7 (2016).

Now Apple has rolled out the iOS 11.2 update to extend this remediation to more iOS devices in the field. These include:

• iPhone 6 encompassing the S and Plus variants, the iPhone SE, the iPhone 5S,
• 12.9” iPad Pro (1st generation), the iPad mini 2 and its successors, the iPad Air, the iPad (5th generation)
• iPod Touch (6th generation)

Here, it means that those commonly-used recent iPhones and iPads are now safe against the KRACK exploit. Check your Settings app on your iOS device to be sure it is up to date with this patch.

These SIM cards will be embedded in subsequent generations of mobile devices including Always Connected PCs

It’s time to embrace the eSIM | Engadget

What Is an eSIM, and How Is It Different From a SIM Card? | How-To Geek

‘Telstra One Number’ Is Telstra’s New eSIM Tech | Gizmodo

eSIM feature to arrive with Windows 10 Version 1803 for always connected PCs | WinCentral

My Comments

A trend that will have an impact on devices that use cellular-based wireless broadband technology is for them to implement eSIM authentication.

What is the eSIM technology?

It is effectively an embedded SIM which is a hardwired equivalent of the SIM card that authenticates you to a mobile-telephony / wireless-broadband service as a customer.

One of the key advantages to this approach over the traditional user-replaceable SIM card is that there isn’t a need to design a large user-accessible space in a mobile device to accommodate one of these cards. Instead, the customer’s wireless-broadband service is provisioned to their device “over the air” rather than having to encode a SIM card to hand over to the customer to be installed in the device. It is similar to the online provisioning and service activation process implemented for some prepaid mobile-telephony / wireless-broadband services sold through ordinary retailers in some markets.

What devices will this appeal to?

This approach appeals to the wearables market where size does certainly matter but is also appealing towards the connected car where there isn’t a desire to create a cavity for a SIM to be installed. Just lately, the eSIM technology is also appealing to the “always-connected” ultraportable laptops thanks to the next major functionality iteration of Windows 10 having software support for this functionality baked in.

Let’s not forget that newer smartphones, USB modems and MiFi routers including multiple-WAN routers will become equipped with eSIM support, especially where multiple-service functionality is to be part of the feature set. It could allow one to design, for example,  an Android smartphone with a classic SIM slot and an eSIM along with a microSD card slot. Here, a user could then benefit from the advantages of multiple services while using a microSD card to provide “infinite” storage for music, photos and videos.

The main disadvantage that the eSIM will offer to some people will be that they can’t switch SIM cards around quickly, which may be of concern with people using a “decoy” number associated with a prepaid service or people who are troubleshooting mobile devices.

What does this allow?

It was brought on board in 2013 but recent improvements to the eSIM standard allowed for a customer to maintain multiple eSIM services from the same or different carriers in the one device. It is similar to how users are switching SIM cards around to maintain multiple service accounts, such as to maintain separate “business” and “private” services, to sign up with “destination-local” mobile-telephony services with a “destination-local” number and payment options, amongst other reasons.

This provides simplification for these users by providing “over-the-air” provisioning for additional services including varying these services or re-instigating dormant services. The user-experience that may be offered is to choose the network that provides the service you want to use then enter an activation code of some sort to “turn on” that particular service. Typically this would be something you receive in an email if you are enrolling online or receive from a staff member at a “bricks-and-mortar” store.

Some carriers and service providers are exploiting eSIM by offering a “one number one account multiple devices” option for their mobile services such as Telstra’s “One Number” service. But there are other ways that mobile-telephony service providers can exploit the emerging eSIM setup. But the carriers can look at exploiting the eSIM further such as tying it in with BYOD business setups, mobile services that can be “parked” when not needed amongst other things.

In some business environments, it could allow a single shared device to be associated with multiple service accounts with the accounts in operation dependent on who is logging in to the device. This could tie in with the “portable desktop” approach towards business telecommunications where one’s computing and telecommunications setup is moved amongst multiple devices but your boss or clients call you at the same extension number.

Conclusion

The eSIM approach for authenticating mobile-telephony and broadband service can open up a wide range of approaches both for device design and for service delivery.

TV setups with large screens and powerful sound systems could also appeal to videocalls where many people wish to participate

A reality that is surfacing with online communications platforms is the fact that most of us prefer to operate these platforms from our smartphones or tablets. Typically we are more comfortable with using these devices as our core hubs for managing personal contacts and conversations.

But there are times when we want to use a large screen such as our main TV for group videocalls. Examples of this may include family conversations with loved ones separated by distance, more so during special occasions like birthdays, Thanksgiving or Christmas. In the business context, there is the desire for two or more of us to engage in video conferences with business partners, suppliers, customers or employees separated by distance. For example, a lawyer and their client could be talking with someone who is selling their business as part of assessing the validity of that potential purchase.

This is more so when there is that family special moment

But most of the smart-TV and set-top platforms haven’t been engineered to work with the plethora of online-communications platforms that are out there. This is although Skype attempted to get this happening with various smart-TV and set-top platform vendors to allow the smart TV to serve as a Skype-based group videophone once you purchased and connected a Webcam accessory supplied by the manufacturer.

The Skype situation required users to log in to the Skype client on their TV or video device along with buying and installing a camera kit that worked with the TV. This was a case of entering credentials or searching for contacts using a “pick-and-choose” or SMS-style text-entry method which could lead to mistakes. This is compared to where most of us were more comfortable with performing these tasks on our smartphones or tablets because of a touchscreen keyboard or hardware keyboard accessory that made text entry easier.

An Apple TV or Chromecast that has the software support for and is connected to a Webcam could simplify this process and place the focus on the smartphone as a control surface for videocalls

The goal I am outlining here is for one to be able to use a smart TV or network-connected video peripheral equipped with a Webcam-type camera device, along with their mobile device, all connected to the same home network and Internet connection to establish or continue a videocall on the TV’s large screen. Such a goal would be to implement the large-screen TV with its built-in speakers or connected sound system along with the Webcam as the videocalling-equivalent of the speakerphone we use for group or “conference” telephone calls when multiple people at either end want to participate in the call.

Set-top devices designed to work with platform mobile devices

A very strong reality that is surfacing for interlinking TVs and mobile devices is the use of a network-enabled video peripheral that provides a video link between the mobile device and video peripheral via one’s home network.

One of these devices is the Apple TV which works with iOS devices thanks to Apple AirPlay while the other is the Google Chromecast that works with Android devices. Both of these video devices can connect to your home network via Wi-Fi wireless or Ethernet with the Apple TV offering the latter option out of the box and the Chromecast offering it as an add-on option. As well, the Chromecast’s functionality is being integrated in to various newer smart TVs and video peripherals under the “Google Cast” or “Chromecast” feature name.

Is there a need for this functionality?

As I have said earlier on, the main usage driver for this functionality would be to place a group videocall where multiple people at the one location want to communicate with another . The classic examples would be for families communicating with distant relatives or businesses placing conference calls that involve multiple decision makers with two or more of these participants at one of the locations.

Most of the mobile messaging platforms offer some form of videocalling capability

In most cases, the “over-the-top” communications platforms like Facetime, Skype, Viber, Facebook Messenger and WhatsApp are primarily operated using the native mobile client app or the functionality that is part of the mobile platform. This way of managing videocalls appeals to most users because of access to the user’s own contact directory that exists on their device along with the handheld nature of the typical smartphone that appeals to this activity.

It is also worth knowing that some, if not all, of the “over-the-top” communications platforms will offer a “conference call” or “three-way call” function as part of their feature set, extending it to videocalls in at least the business-focused variants. This is where you could have multiple callers from different locations take part in the same conversation. Such setups would typically show the “other” callers as part of a multiple-picture “mosaic” on the screen. Here, the large screen can come in handy with seeing the multiple callers at once.

How is this achieved at the moment?

At the moment, these set-top platforms haven’t been engineered to allow for group videocalling and users would have to invoke screen-mirroring functionality on their mobile devices once they logically associate them with the video endpoint devices. Then they would have to position their mobile device on or in front of the TV so the other side can see your group, something which can be very precarious at times.

How could Apple, Google and co improve on this state of affairs?

Should this still be the way to make group videocalls on your Apple TV or Chromecast?

Apple and Google could improve on their AirPlay and Chromecast platforms to provide an andio-video-data feed from the video peripheral to the mobile device using that peripheral. This would work in tandem with a companion Webcam/microphone accessory that can be installed on the TV and connected to the set-top device. For example, Apple could offer a Webcam for the latest generation Apple TV as an “MFi” accessory like they do with the game controllers that enable it to be a games console.

When users associate their mobile devices with a suitably-equipped Apple TV / Chromecast device that supports this enhancement, the communications apps on their phone detect the camera and microphone connected to the video peripheral. The user would then be able to see the camera offered as an alternative camera choice while they are engaged in a videocall, along with the microphone and TV speaker offered as a “speakerphone” option.

What will this entail?

It may require Apple and Google to write mobile endpoint software in to their iOS and Android operating systems to handle the return video feed and the existence of cameras connected to the Apple TV or Chromecast.

Similarly, the tvOS and Chromecast platforms will have to have extra endpoint software written for them while these devices would have to have hardware support for Webcam devices.

At the moment, the latest-generation Apple TV has a USB-C socket on it but this is just serving as a “service” port, but could be opened up as a peripheral port for wired MFi peripherals like a Webcam. Google uses a microUSB port on the Chromecast but this is primarily a power-supply and network-connection port. But they could, again, implement an “expansion module” that provides connectivity to a USB Webcam that is compliant to the USB Video and Audio device classes.

These situations could be answered through a subsequent hardware generation for each of the devices or, if the connections are software-addressable, a major-function firmware update could open up these connections for a camera.

As for application-level support, it may require that the extra camera connected to the Apple TV or Chromecast device be logically enumerated as another camera device by all smartphone apps that exploit the mobile phone’s cameras. The microphone in the camera and the TV’s speakers also would need to be enumerated as another communications-class audio device available to the communications apps. This kind of functionality could be implemented at operating-system level with very little work being asked of from third-party communications software developers.

User privacy can be assured through the same permissions-driven setup implemented in the platform’s app ecosystem that is implemented for access to the mobile device’s own camera and microphone. If users want to see this tightened, it could be feasible to require a separate permissions level for use of external cameras and audio-input devices. But users can simply physically disconnect the Webcam from the video peripheral device when they don’t intend to use it.

An alternative path for app-based connected-TV platforms

There is also an alternative path that smart-TV and set-top vendors could explore. Here, they could implement a universal network-based two-way video protocol that allows the smart TV or set-top device to serve as a large-screen video endpoint for the communications apps.

Similarly, a smart-TV / set-top applications platform could head down the path of using client-side applications that are focused for large-screen communications. This is in a similar vein to what was done for Skype by most smart-TV manufacturers, but the call-setup procedure can be simplified with the user operating their smartphone or tablet as the control surface for managing the call.

This could be invoked through techniques like DIAL (Discovery And Launch) that is used to permit mobile apps to discover large-screen “companion” apps on smart-TV or set-top devices in order to allow users to “throw” what they see on the mobile device to the large screen. As well, the connection to the user’s account could be managed through the use of a session-specific logical token established by the mobile device.

This concept can be taken further through the use of the TV screen as a display surface, typically for communications services’ messaging functions or to show incoming-call notifications.

Update

Apple has answered this issue with their tvOS-based Apple TV set-top box platform in June 2023. Here, they are implementing a dual-device approach with iPhones or iPads running iOS/iPadOS 16 being linked with Apple TV set-top boxes that run tvOS 17. Here, both devices can be used to handle a videocall on FaceTime, Zoom or an increasing number of other popular platforms with the TV’s screen and audio system handling the picture and sound of the caller at the other end while the iOS device’s microphone and camera picks up your face and voice for the other party to see and hear.

You can start the call on the iPhone’s handheld interface and “throw it over” to the Apple TV or you can start the call from the Apple TV’s lean-back interface and use the iPhone associated with your Apple TV for microphone and camera functionality. Apple is to sell a cradle for the iPhone so that it can be positioned in fromt of the TV with the rear camera facing the participants.

Conclusion

What we still need to think of is to facilitate “dual-device” videocalling with the popular mobile platforms in order to simplify the task of establishing group videocalls using TVs and other large-screen display devices.
