Here's how WhatsApp tailored its app for KaiOS

With tens of millions of users, WhatsApp is the marquee app on KaiOS — and it is steadily getting new features.

We haven't really talked about KaiOS a lot here, but the operating system is now installed on over 100 million phones, making it the third-largest mobile operating system in the world. KaiOS is a fork of Firefox OS that's designed for feature phones, and over the last three years it has seen a meteoric rise because of devices like the $15 JioPhone in India and Nokia's 8110.

While entry-level Android phones have gotten much better over the years — particularly with the introduction of Android Go — there are still tens of millions of users who turn to feature phones for their affordability. And with KaiOS, feature phones now come with a web browser, a dedicated app store, and even Google Assistant baked in.

Then there's WhatsApp. The Facebook-owned messaging platform made its debut on KaiOS last year, and is now pre-installed on KaiOS phones globally. WhatsApp already counts tens of millions of users on KaiOS, and that's not surprising when you consider that the service has 400 million users just in India. KaiOS phones are aimed at India and other emerging markets in the Middle East and Africa, and these are countries where WhatsApp usage is ubiquitous.

WhatsApp on KaiOS is very similar to what you'll find on Android. You get all the messaging features, including group chats, and a lot of extras. The best part is that the KaiOS version also has end-to-end encryption, just like the Android client. So I talked to Joe Grinstead, software engineering lead for WhatsApp on KaiOS, on how the service was tailored for KaiOS and what we can look forward to in the future.

WhatsApp has been built from the ground up for KaiOS.

KaiOS presents a unique challenge because of the fact that it is designed to run on low-cost hardware. Most features phones based on the operating system have 256MB or 512MB of RAM and internal storage up to 4GB. And because there's no touchscreen, all the navigation on the user interface is on a directional pad and text is entered via a T9 keyboard.

Grinstead mentioned that as KaiOS is built on Firefox OS, it is essentially a web browser that has HTML5 and JavaScript. So most of the time, an app for KaiOS is nothing more than a mobile version of a website that's stored locally on the device. But as WhatsApp does not have a mobile site, the app for KaiOS had to be built from scratch. And while WhatsApp looks simple and has a barebones interface, it has an exhaustive list of features on Android:

Grinstead said his team had to focus on features they could actually deliver on the platform and make them work reliably, settling on a "minimum viable product" that they could launch with and still call it WhatsApp. As such, there are a few features missing from WhatsApp on KaiOS, including voice and video calls, WhatsApp Web, chat backups, custom notification tones, and more.

That said, all the core features are here. You get one-on-one and group chats, the ability to share photos and videos, contact and location sharing, transferring money over UPI in India, and voice messages. Grinstead mentioned that the voice messaging feature in particular gets a lot of use on KaiOS because it is easier than the T9 keyboard.

WhatsApp's Status feature is rolling out to KaiOS shortly.

Grinstead and his team are working on adding more features to WhatsApp for KaiOS. The Status feature is at "Gold Master," meaning it is ready to roll out to the platform. It is a big deal that the feature is making its way to KaiOS, and Grinstead stated that his team is working on introducing more features to the platform over the coming months. It's unlikely we'll see feature parity with Android — that's just not possible given the constraints with KaiOS — but it is good to see WhatsApp actively working on new feature additions.

The fact that KaiOS phones run low-end hardware means WhatsApp had to optimize the app to ensure it didn't run into performance issues. Grinstead said the database structure had to be rewritten because the performance was terrible once the phone filled up with data. It would take around 20 seconds to open WhatsApp on KaiOS, and because there is no multitasking on the platform, every time you open the app, you need to wait for it to launch. The hardware just isn't robust enough to run apps in the background.

Optimizing the database structure allowed Grinstead and his team to bring down the launch time to three seconds. Further optimizations include showing a low-quality version of a photo instead of the original resolution to save on bandwidth, and there are limits for video sharing on the platform — 50MB on the JioPhone, and 35MB on other devices. KaiOS normally allows 1GB for apps, but because WhatsApp stores data locally, it gets an additional 1GB allocation for storing texts and media. The app also shows a low storage warning on KaiOS that gives you the option to free up space. Interestingly, there is also the ability to write natively to an SD card.

Then there's the issue of navigation itself: because there's limited screen real estate on a feature phone and the resolution is usually 320 x 240 pixels, WhatsApp's UI had to be pared down to fit the confines of the screen. The mockups below illustrate the point well:

Now, WhatsApp is different from most messaging platforms in that all your data is stored locally. Because it has end-to-end encryption, all associated data — including chats and multimedia — is stored on-device instead of a server. Then there's the issue of push notifications: because KaiOS is effectively a browser, WhatsApp has to manage push notifications over HTML5, with Grinstead noting, "I don't know if anyone else is doing HTML5 push notifications with anything as complicated as WhatsApp."

End-to-end encryption is a big deal, particularly on a feature phone.

As Grinstead explained, that's because the text that shows up in the notification has to be decrypted locally — the server doesn't provide a preview of the incoming text because of end-to-end encryption. WhatsApp relies on the Signal protocol for end-to-end encryption, and the libsignal protocol itself is now baked into KaiOS, making it that much easier to deliver fully encrypted chats.

One of the major issues with end-to-end encryption is group chats — your phone essentially has to create one-to-one handshakes with everyone in a group before a message is sent. Grinstead stated that the first message you send to a group is the most complicated, because that's when a lot of the initial handshakes occur. Because of the limited resources on offer, Grinstead and his team had to tweak delivery notifications so they wouldn't crash a phone. Instead of sending all the information at once, the delivery server now waits for the phone to acknowledge that there's enough RAM to handle incoming requests.

As for the features that are still missing, Grinstead said that voice calling has been "particularly challenging." There's no timeline for when (or if) the feature will be available on KaiOS. The other notable omission is WhatsApp Web, and similarly there's no update as to when it will show up on KaiOS.

WhatsApp launched on KaiOS in July 2019, and it racked up one million downloads in just under 24 hours. It had 10 million users in two weeks, and the company says it has "tens of millions" of users on KaiOS now. Mozilla is once again involved with KaiOS, and that should allow the platform to switch to a new engine with more modern web features baked in.

That should give WhatsApp more wiggle room to introduce new features. We may even get to see voice calling on the platform as a result.

Samsung Access gives you a new phone, extra perks for one monthly fee

Samsung Galaxy S20 Display 2

Apple was one of the first manufacturers to offer a subscription service for phone upgrades, allowing users to get the latest iPhone for one flat monthly fee. 

Samsung offered a similar program too, and it’s now offering an all-new upgrade program called Samsung Access (h/t: XDA-Developers). So how does it differ from the legacy Samsung Phone Upgrade Program, then?

The Samsung Access initiative includes a number of perks aside from being able to upgrade your phone. These perks include Premium Care protection and support, and Microsoft 365 Personal (including 1TB of OneDrive storage and premium Office apps).

There are a few caveats though, as you need to return your current device before upgrading. Furthermore, you can only upgrade after a minimum of nine months, and you can only cancel after three months. Want to upgrade or cancel earlier than that? Then you’ll need to splash out $100, Samsung says.

It’s also worth noting that there are separate prices for each Galaxy S20 device, with the standard S20 retailing for $37 a month on Samsung Access. Opt for the Galaxy S20 Plus and you’ll be paying $42 a month (or $46 for the 512GB option), while the Galaxy S20 Ultra retails for $48 a month. The S20 and S20 Ultra models are only available in 128GB flavors via this initiative. 

Furthermore, you can’t trade in your current phone to join Samsung Access. Meanwhile, Samsung’s legacy upgrade plan allows you to do this. Like the idea of this Samsung Galaxy subscription program nonetheless? Then check out Samsung Access via the button below.



ACLU's app captures police misconduct even if they smash your phone

Back in 2015, the American Civil Liberties Union (ACLU) launched an app called "Mobile Justice" that is designed to help John and Jane Doe record police misconduct. But the cops can grab your phone, you retort. True, but videos recorded with the app are automatically sent to the ACLU's servers just in case the cops try to pull a fast one. The app has three functions: Record, Witness, and Report.

Record is used to film an incident involving possible police misconduct, and there is a test button that allows users to make sure that their camera is working. Once the recording ...

From the Editor's Desk: Protest under assault

I have this vivid memory from the early days of 2020 that won't subside.

It was January 6, before CES officially began, and I was at the Cosmopolitan hotel looking at Fossil's new smartwatch offerings. The demo was finished and I was standing on this expansive balcony overlooking the city, a fake Eiffel Tower looming to my right. I was claiming a minute just for me, while inside my coworkers were chatting away contently. It was one of those really nice moments that you have to intercede on your own behalf to remember, to crystallize it so that, whatever happens in the future, you can draw upon it for reinforcement.

I've been drawing on it a lot lately, as the world seemingly crumbles around me. I'm safe and healthy and in no immediate danger, and for that I'm incredibly thankful. And I'm also angry. The slow burn of this year, the shelter-in-place of it all, spilled out into the streets in recent days, first as a trickle and then, over the past couple nights, as a deluge.

Now there's another image I can't get out of my head. It's of an NYPD cruiser careening into a group of protestors as they attempt to set up a blockade. People fly in every direction, and most hit the ground hard. In the context of the last few days, it's a small act of aggression, but it's one in an accumulation and escalation of violence that needs to be quickly condemned and then examined for its sheer malevolence. Police have the power, and they are abusing it.

Black people in the U.S. deserve to feel safe wherever they go. They deserve to feel free in places they live and in places they don't. They deserve to be given the benefit of the doubt, just as white people often are, when it comes to public discourse and action taken. They deserve not to be killed by police.

The protests taking place around the U.S. are a response to the inaction black people feel by governments at every level. The rioting and looting a processing of those pent-up feelings. If you're not a black person in the U.S., your job is to listen and try to understand, not judge people for acting as a force for change. If you feel that George Floyd, and so many other innocent black citizens over the past few years, didn't deserve to die, your job is to be an agent for change in your own way, by donating to good causes — in the short-term, bail funds and longer-term, the campaigns of those running in elections at every level looking to subject the current policing system to severe scrutiny.

This shouldn't be a partisan issue. The abuse of power at any government level shouldn't be tolerable, and what's happened — and captured on video again and again and again — over the past few nights is sickening. It's horrifying. And it has to stop.

Black lives matter.

What to expect from the next generation of Android phone processors

Samsung Galaxy S20 Ultra home screen against metal door

Arm has revealed its latest crop of CPUs and GPUs, set to be used in Android phone processors later this year and in 2021. From Qualcomm and Huawei to Samsung and MediaTek, we’re expecting all the major silicon players to use the new tech.

Speaking of these chip companies, what should we expect from them and the mobile SoC industry at large next year?

A massive leap in CPU power (for some)

Arm Cortex X1

The next generation of Android processors could see the biggest CPU performance leap in quite some time, as the new Cortex-X1 Arm CPU prioritizes power over efficiency. This strategy means you can expect a power increase of up to 30% compared to the Cortex-A77 used in Qualcomm, Samsung, and MediaTek’s flagship chipsets. In fact, the Cortex-X1 is expected to be up to 23% more powerful than the Cortex-A78, announced alongside the X1.

Arm has stated that the Cortex-X1 might only be available to specific chipset makers, meaning some chip brands might be left without the hefty CPU. So expect a rather uneven playing field among Android phones if for example, Qualcomm gets access to this Arm CPU but Samsung or MediaTek don’t.

What to expect from GPUs in 2021

Arm Mali G78

Arm’s Mali-G78 GPU is a modest upgrade over the Mali-G77 seen in Samsung and MediaTek’s high-end chips. So truth be told, mobile gamers might not see a major real-world difference between the two GPUs.

This puts Arm in a rather interesting situation in 2021, especially in light of Samsung’s decision to work with AMD on smartphone GPUs. Back in July last year, Samsung said the new GPU tech will be implemented in products that launch “two years down the road,” which means it’s eyeing a 2021 launch date.

Combine Samsung and AMD’s partnership with Qualcomm’s traditionally beefy Adreno graphics, and it seems like Arm GPUs aren’t exactly hot property right now at the high end.

In saying so, the company’s Mali-G68 is the first Arm GPU in an upper mid-range family, sharing the same features as the Mali-G78 and slotting in above the Mali-G5X series. We’ve previously seen the likes of Xiaomi use a flagship Arm GPU (albeit with four cores) to great effect in the Redmi Note 8 Pro. So hopefully the G68 bring even more graphical grunt to mid-range phones.

GPUs are more important than ever in the age of high refresh rate screens, and we’re also starting to see even $200 to $300 phones offer 90Hz or 120Hz displays. High refresh rates don’t mean much if the GPU struggles to keep up, so that’s another reason why we’re glad to see the Mali-G68 plug the gap between budget and flagship mobile processors.

A switch to more efficient designs

Qualcomm Snapdragon 865 in plastic case

The manufacturing process used to make each chipset (measured in nanometers) is another important factor, with smaller designs equaling less power consumption. We’ve seen top-end mobile processors shrink from 28nm designs in early 2014, all the way to 7nm right now.

High-end Android phone processors are due for a switch to even smaller 5nm designs in 2021, and we’re expecting major players to all hop aboard this bandwagon. But mid-range chips usually lag behind in this regard, so they might offer 7nm or slightly bigger designs for a while yet.

New CPUs also tend to offer efficiency improvements, and Arm’s Cortex-A55 is the lightweight CPU of choice for all silicon makers, being paired with more powerful CPUs. The Cortex-A55 is long in the tooth though, having first been revealed in 2017. Unfortunately, Arm hasn’t revealed a successor to it yet, which is disappointing as it’s probably more efficient to use the newer heavyweight cores for many tasks instead. Hopefully we see a successor next year, as it could provide a major upgrade for $100 to $150 phones.

What about 5G?

The Snapdragon 765 series processor for Android phones.

The shift to 5G brought with it a few aches and pains, and power consumption is one of these issues. Fortunately, the aforementioned shift to 5nm designs means new 5G chipsets will consume less power.

We’re also expecting to see the likes of Qualcomm adopt integrated modems in their flagship chipsets, enabling notable efficiency gains as well. And when combined with the switch to 5nm designs, we can expect next year’s 5G flagships to be kinder on battery life than this year’s devices.

Qualcomm’s latest X60 modem also brings a number of enhancements, such as 5G Voice-over-NR capabilities, and improved carrier aggregation for better speed and stability. The US chip giant is also bringing smaller mmWave modules to smartphones in 2021, with smaller components meaning more room for (you guessed it) bigger batteries.

Qualcomm’s rival MediaTek is also poised to improve its 5G capabilities in the future. The company still doesn’t support mmWave just yet, but previously told Android Authority that it was working on a solution.

Connectivity to get upgrades

Android Bluetooth Notification Menu Icon

Wi-Fi 6 has come to a variety of phones in 2019 and 2020, as some of the latest high-end and upper-mid range processors sport the standard. We’ve even seen the tech come to the budget-focused Snapdragon 460 chipset, although phones with that chip are only due closer to the end of the year.

Just when more chipsets and phones adopt Wi-Fi 6, we’ve got Wi-Fi 6E entering the fray. Don’t expect much faster speeds, but it should ease congestion and result in reduced latency. The first phones with Wi-Fi 6E are dependent on processor support, so we’ll need to wait and see if upcoming Snapdragon, Dimensity, and Kirin chips gain this feature.

In saying so, Qualcomm announced Wi-Fi 6E support in its new FastConnect 6700 and 6900 connectivity suites. FastConnect is Qualcomm’s brand name for the wireless connectivity components in its recent Snapdragon chips, so this means we can definitely expect Wi-Fi 6E in its upcoming premium mobile processors.

Read: What is Wi-Fi 6E and unlicensed 6GHz spectrum?

Bluetooth is another important connectivity feature and many high-end chipsets support Bluetooth 5.1, with some upper-mid range SoCs grabbing this feature too. However, we’ve already seen the first processor packing Bluetooth 5.2 support in the Snapdragon 768G, with Qualcomm later adding that Bluetooth 5.2 was coming to the aforementioned FastConnect suites.

Bluetooth 5.2 brings enhancements like Low Energy Audio (LE Audio) for more power-efficient wireless audio, Audio Broadcast support as well as the LC3 codec. Again, this will require new SoCs if you want in on this action. But the new standard means you’re getting better audio quality and more reliable connections than relying on proprietary AptX connectivity, so it’s definitely worth the wait.

Machine learning in 2021

MediaTek AI bannerhead

It seems like every major chip manufacturer has a neural processor of some kind in 2020, with Huawei, MediaTek, Qualcomm, and Samsung all sporting NPUs, APUs, or AI accelerators. We’ve seen virtually all flagship Android processors offer AI silicon, while brands have also moved to bring this hardware to the mid-tier.

However, one trend we’ve noticed is that chipset makers aren’t bringing machine learning hardware to low-end processors right now. We aren’t expecting to see this change in 2021, as CPU and GPU advancements mean many machine learning tasks can be run at a brisk pace without a dedicated neural processor. Furthermore, CPU and GPU upgrades also mean that machine learning tasks aren’t as big a drain on the battery as they used to be.

Nevertheless, as smartphone brands keep pushing the envelope with offline inference tasks like Live Caption, augmented reality, and ultra high-resolution processing, we expect more chips to offer dedicated silicon.

What does this all mean for Samsung Exynos?

Samsung Exynos 990

The Exynos 990 garnered a ton of negative attention due to the real and perceived gap between it and the Snapdragon 865 chipset. But there’s reason to believe that 2021 will be a rebuilding phase for Samsung’s chipmaking unit.

Related: Ditching custom CPUs is the right call for Samsung’s Exynos

Aside from the aforementioned partnership with AMD for graphics, Samsung’s CPU efforts have also been shaken up. The firm’s Austin custom CPU unit was shut down late last year, which means future Samsung CPUs are almost 100% guaranteed to use Arm Cortex technology.

It seems like a good time for Samsung to drop its own CPUs in favor of Arm CPUs, as the Cortex-X1 seems to have a similar performance-focused philosophy to the Korean brand’s CPUs. We don’t know if we’ll see the first Samsung Exynos chipset with AMD graphics in 2021, but you might want to keep your expectations in check for the first product. After all, this is AMD’s first foray into modern smartphone GPUs.

Where do these developments leave Huawei?

Huawei P40 Pro Huawei logo boot screen

Huawei’s HiSilicon division has been a saving grace ever since the Huawei ban kicked in, giving the manufacturer in-house chip manufacturing capabilities. And this was vitally important with Qualcomm not being allowed to supply the firm, as HiSilicon processors helped to address this gap.

Unfortunately, Washington’s draconian decision to now cut Huawei off from its chip producers means the firm is in dire straits as far as Android processor supply is concerned. The Chinese brand said that it had been building a stockpile of chipsets, and the new US amendment still apparently allows for some chips currently in production to be shipped to Huawei. But this will significantly affect the company’s ability to develop the latest and greatest technology. What’s the point of designing a chip if your chip producer can’t actually manufacture it for you?

One possibility is that Huawei turns to alternative chip producers like Samsung or smaller foundries in China. But this will be contingent on these producers not using a significant amount of US know-how to make processors. However, it’s believed Huawei has turned to Chinese foundry SMIC to produce some chips. But these are 14nm designs rather than anything close to 7nm seen on current flagship SoCs.

Another deciding factor for Huawei’s 2021 aspirations is its relationship with silicon designer Arm, as the Chinese brand uses Arm CPUs and GPUs in all its in-house processors. At the time the US trade ban was initiated in May 2019, Arm said that it was complying with the regulations. But the chip designer was then quoted as saying in October 2019 that Huawei has access to next-generation technology.


The latest Arm CPUs and GPUs are clearly a mix of evolution and revolution for the company, with the Cortex-A78 and Mali-G78 being in the former camp. Meanwhile, the Cortex-X1 and Mali-G68 represent new ventures for the Android processor landscape. But this is just the tip of the iceberg for 2021.

Between Huawei’s silicon troubles, Samsung ditching custom CPUs and adopting AMD GPUs, and maturing 5G technology, 2021 is clearly shaping up to be a big year for the industry.

Thanks to the Video Doorbell Pro's built-in speakers and mic, you can talk to visitors without leaving your kitchen. You can also get alerts sent straight to your device any time the Ring Video Doorbell Pro detects motion or someone rings the doorbell.

Outside of checking on the front door, there are plenty of other things you can do with the Echo Show 5. Manage your calendar, make to-do lists, get updates on the weather, traffic, or news, and even cook along with recipes. Use the display to watch your favorite shows, listen to the radio, or keep up with the latest audiobooks and podcasts.

The Video Doorbell Pro will replace your existing hardwired doorbell, and it comes with one of four different colored faceplates so you can match the exterior of your home. Then you just leave it there! The Pro is designed to work in any temperature with an operating range between -5 and 120 degrees Fahrenheit.

The camera has a 160-degree field of view that covers a huge space in front of your door. It can record in 1080p resolutions for crystal clear video, and there are integrated infrared LEDs so you can still see who's at the door even at night. The video that gets transmitted is extra secure, too, thanks to bank-grade encryptions.



Get some great sound and save $20 with the Soundcore Liberty 2 Pro earbuds

Best Buy has a whole new set of deals of the day, and the Anker Soundcore Liberty 2 Pro true wireless earbuds are part of the savings. Get a pair for $129.99, which is down from the usual price of $150 and a match for one of the lowest we've seen this year. The last time we saw them go any lower than this was back in February when they dropped to $120. You can also find today's drop on Amazon, and that sale includes the white versions.

These earbuds have eight hours of playtime per earbud, and you can use the earbuds independently to extend that use. The charging case they come with adds another three full recharges before you ever need to plug into a wire to juice back up. With a quick charge of just 10 minutes inside the case you can get an extra two hours of playtime. Plus, the charging case can be recharged via USB-C or a Qi-compatible wireless charging pad, giving you plenty of options for keeping these batteries topped off. RAVPower has a wireless charging pad on sale for $5 off when you clip the on-page coupon.

The Astria coaxial acoustic architecture helps eliminate interference and produces harmonized treble and bass for fantastic sound. The 11mm dynamic drivers support the immersive audio and create an expansive soundstage. The HearID technology inside the earbuds helps analyze your hearing profile and creates tailor-made sound just for you so anyone using these earbuds gets the perfect listening experience.

The earbuds also have microphones built in so you can use them to answer calls. The four mics combined with cVc 8.0 noise reduction technology helps ensure your voice stays crystal clear and no background noise interupts you.

Read more about the Soundcore Liberty 2 Pro in our review that gave them 4.5 stars out of 5 and a Recommended badge. Daniel Bader said, "The Liberty 2 Pro are an incredible pair of true wireless headphones that are easily worth their steep $150 asking price." Good thing they're cheaper now!



How to install Linux on your Chromebook

Chromebooks can do a lot right out of the box. However, if you want just a little more, you can install Linux apps to most newer models (see the full list here) and have access to a complete catalog of desktop-class applications.

How to enable Linux

Your Chromebook already runs Linux because Chrome is its own Linux distribution, but it's a very locked-down version without access to most Linux tools and programs by default. Luckily, turning everything on is easy.

  1. At the bottom right of your system tray, click on the clock.
  2. Select the gear icon to open the settings.

  3. Scroll down until you see "Linux (Beta)" and choose Turn On.
  4. Read and follow the simple on-screen prompts and wait for things to finish. This could take 10-15 minutes.

  5. Once the terminal window opens, you are ready to type Linux commands. You can always find the Linux terminal in your app drawer if you choose to close it now.
  6. At the terminal command prompt, type the following command to update your package list and packages themselves: sudo apt-get update && sudo apt-get dist-upgrade. Be sure to use the correct spacing when typing this command.
  7. Restart your Chromebook.

You are now ready to install and run most any Linux program found in the base Debian Stretch repositories. A full list of them can be found here.

Not every piece of Linux software will work on your Chromebook, and all Linux programs run inside the same sandbox. You also can't use the microphone or webcam, and hardware acceleration is not yet supported. You'll still find a lot of great software that can make your Chromebook more useful and powerful.

Google Pixelbook Go

From $850 at Amazon

Pricey, but worth every penny

The Pixelbook Go is the best premium Chromebook you can buy right now. It doesn't support a pen or fold over onto itself, but for getting work done on a laptop that's purely a laptop, it's tough to beat it.

The Pixelbook Go is one of the more expensive Chromebooks on the market, but for all you get, it's worth it. You get a fantastic keyboard, excellent battery life, and an Assistant key that lets you connect to the company's smart assistant at any time. It is, like we said, pricey, but there are plenty of other great Chromebooks out there if you're looking for something different.
