Xiaomi releases kernel sources for the Mi 10 Ultra and Redmi 7/Y3 Android 10 builds

Of late, Xiaomi has been doing a great job of releasing kernel sources for newly launched devices. Earlier this year, the company released the kernel sources for its flagship Mi 10 series on the day the devices were unveiled. Similarly, kernel sources for the Redmi K30 Pro were released just a few days after the device was announced. In keeping with the trend, Xiaomi has now released kernel sources for the recently launched Mi 10 Ultra.

The Samsung Galaxy Note 20 Ultra features NFC, eSIM, and UWB tech in a single NXP chip

Earlier today, we learned that the Samsung Galaxy Note 20 Ultra is the first Android smartphone to feature Samsung’s new Variable Refresh Rate (VRR) OLED display, which makes use of adaptive frequency technology to reduce power consumption by up to 22%. But that’s not the only new feature to make its way to users with Samsung’s latest flagship. The Galaxy Note 20 Ultra is also the first Android smartphone to feature support for Ultra-Wideband (UWB) technology, which enables a host of new features like faster file sharing, the ability to unlock smart doors and find the location of compatible devices near you, and more.

During the launch event, Samsung briefly highlighted the potential uses for the new UWB technology and the company later shared a video explaining the technology and its utility in greater detail. However, Samsung didn’t reveal much about the hardware that enables the new feature on the Galaxy Note 20 Ultra. Thankfully, Dutch semiconductor manufacturer NXP has now revealed some key details about the hardware solution that powers UWB on Samsung’s latest flagship.

According to a recent press release shared by the company, the Samsung Galaxy Note 20 Ultra makes use of a single NXP chip for UWB fine-ranging, NFC, and eSIM capabilities. Talking about NXP’s combined UWB solution, Inkang Song, VP and Head of Technology Strategy Group of IT & Mobile Communications Division at Samsung Electronics, said, “For the first time in a Galaxy device, Samsung is integrating NXP’s UWB technology into our latest Galaxy Note20 Ultra to make sharing photos, videos and files easier. We are excited to introduce future UWB functionality in our Galaxy devices that will help locate items more accurately with AR technology and unlock your home as a digital key that will make life easier for consumers.”

Along with the aforementioned use cases, NXP claims that its combined UWB chipsets can enable the following features:

  • Completely hands-free access control: The unparalleled precision sensing of NXP’s Secure UWB technology includes outstanding localization that will make it possible for mobile devices to communicate with connected doors, points of entry, and cars for completely hands-free access control.
  • Simplified integration: Building on NXP’s NFC connectivity, mobile ecosystems expertise and proven security architecture found in many of today’s popular mobile payment-enabled devices, UWB can be part of a system that quickly and securely initializes communication. With NFC onboard, devices can continue to perform contactless transaction even when they run out of battery.
  • The next generation in connectivity: Unlike traditional SIM cards that must be removed and replaced in new devices, NXP’s GSMA-compliant eSIM solution is integrated permanently into a device, making remote SIM provisioning radically easier and providing over-the-air SIM updates. The external SIM slot plus eSIM allow end users to have two or more phone numbers on a single device. The eSIM functionality comes with all Samsung Galaxy Note 20 Ultra devices, excluding China, Japan, and Korea.

Telegram v7.0.0 beta adds video calls and prepares to support Bubble notifications in Android 11

Telegram is undoubtedly one of the most feature-rich messengers out there, but it lacks one crucial feature that’s available on most alternatives — video calling. The lack of video calling and group video calling support means that Telegram users have to rely on other messengers like WhatsApp and Google Duo to use these features, but that is bound to change soon. Earlier this year, Telegram announced that it will finally add video calling support to the messenger this year. As promised, Telegram is now rolling out version 7.0.0 on the beta channel and it brings video calling support, among other things.

The video calling feature was recently spotted by @alex193a in Telegram v7.0.0 beta for iOS, Android, and macOS. As you can see in the attached screenshot, you can access the video calling feature by tapping the three-dot menu icon in the top right corner of any chat and it’s enabled by default on the latest beta release. However, in order to use the feature, you and the other participant need to have Telegram v7.0.0 beta installed on your devices.

While Telegram hasn’t officially announced anything about the video calling feature yet, we believe that it should reach the stable channel in the coming weeks. Along with the video calling feature, the latest Telegram beta also reveals that the app will soon receive support for Android 11’s Bubble notifications.

Telegram v7.0.0 Beta Bubbles in Android 11

Telegram first started testing floating chat head bubbles late last month in version 6.3.0 beta of the app, which could be enabled via a debug option in the app’s settings. However, the debug option didn’t enable native Bubbles in Android 11. With the latest beta release, Telegram’s chat head bubbles now work with Android 11’s native Bubbles API, but you still need to enable the debug option. As you can see in the attached screenshot, the chat bubbles appear in the Conversations section of the notification shade.

These specs might not seem all too impressive, but this is meant to be a productivity device first and foremost. Productivity devices generally don’t need the latest and best specs, but instead a meaningful combination of specifications that can make the device function in the best manner possible. Microsoft made it very clear that they cared about thickness and weight more than almost anything about this device, and it shows. The device will likely perform well for its lifespan.

Design and Display

The display’s on the Surface Duo are very special. There are two identical 1080p PixelSense AMOLED displays. They both come with a 4:3 aspect ratio and 1800×1350 pixel resolution each. They both cover 100% of the sRGB and DCI-P3 color gamut.

The display panels aren’t all too impressive, but the technology Microsoft put into them is. Both displays use Microsoft’s proprietary dual-screen calibration. This is to make sure both displays are 100% identical. The two displays should be indistinguishable from each other. The displays support Microsoft Active Pens, so you can use any of the recent Surface Pens on them.

The phone is incredibly thin at just 4.8mm while unfolded, which as you see above, is just a tad bit thicker than the USB Type-C port. This is by far one of the thinnest devices to launch in recent memory. While folded it is still a slim 9.9mm, actually coming in very close to the Galaxy S20 Ultra. While unfolded, you can use either the two displays as two separate displays running two separate apps, or two parts of one app, or rotate the display and use it as an 8.1″ tablet.

Just like the Surface Book 3, the Surface Duo is a very adaptive device. On the Surface Duo, you can fold the display 360 degrees. It’s a full display hinge. It also uses watch mechanics to lock into place, so you can fold it half-way like a laptop or into a tent shape for watching something like Netflix or YouTube.

Software Experience

Microsoft made this device a dual-screen because they said there was something natural about windows and the flow of having two screens. Microsoft says on a single screen device you are always having to lose focus by closing apps and switching, it breaks focus and flow. The idea was that having two screens that intelligently work together is much better than a single screen. The Surface Duo’s two screens let you drag and drop images, files, and text along with apps to get work done faster. Microsoft has adapted its Office suite of apps and OneDrive to span across the displays, and some third-party apps like Amazon Kindle can mimic a book-like reading interface to take advantage of the dual-screen design. Outside of these, any Android app should work on each of the displays, even if they aren’t necessarily taking advantage of the design. Microsoft has also created APIs for dual-screen apps to work in the Android codebase, and it plans to upstream them for other manufacturers and third parties to use.

This is the intangible aspect of it. It’s not much larger than your average glass slab phone yet it offers much more versatility and theoretical productivity. It lets you work without stopping. There’s no need to stop to switch apps or close an app to copy and paste or even switch apps to open a link. It just lets you open it on the second screen. LG tried to make a dual-screen device, but even after multiple attempts, there’s still scope for improvement in key areas. The software just wasn’t there, the dual-screen case felt bulky, and the dual-screen felt like an afterthought. The Surface Duo fixes all of these issues.

This phone is not for everyone, though. As Microsoft told us, this is a phone for Surface and Office fans. It doesn’t have a fancy high refresh rate display or quad-camera setup or insane fast charging. It was just designed to take the Surface aesthetic Microsoft has been working on for years and bring it to mobile. It is truly a Microsoft phone, and that by no means is a bad thing. It just means the phone is not going to be for everyone, and that’s fine. Microsoft knows who this phone is for and who it is going to sell to. It’s not the Android enthusiasts or early adopters, but the Surface fans.

Microsoft Surface Duo: Pricing and Availability

The Surface Duo will be available for pre-order starting today in the US. The phone will cost $1,399 for the base 128GB/6GB model. It will also be available in a 256GB/6GB model. You can pre-order it from the Microsoft Store, Best Buy, or AT&T. The phone will be available in-store and online from September 10, 2020, onwards. It only comes in one color, Glacier. It will come in an Unlocked version and also a locked AT&T model. The unlocked model has eSIM while the AT&T model does not. Microsoft has decided not to provide any pre-order bonuses with the device, but you do get a bumper cover in the box.

ZTE says their A20 5G will be the first smartphone with an under-screen camera

In the quest to create a completely bezel-less smartphone, manufacturers have been working on under-screen camera tech for the last couple of years. While we’ve already seen prototypes from Samsung Display, OPPO, and Xiaomi, the under-screen camera tech is yet to make its way to consumers. But that might change soon. In a recent post on Chinese social media platform Weibo, ZTE’s President for Mobile Devices, Ni Fei, has confirmed that the company will be the first to launch a smartphone with an under-screen camera.

As you can see in the attached screenshot, the post itself doesn’t reveal any details about the upcoming smartphone or its launch date. However, if you look closely, you can see that Fei used a device called ‘ZTE A20 5G under-screen camera’ to make the post. This confirms that the ZTE A20 5G will be the first production smartphone to feature an under-screen camera sensor.

While the company hasn’t revealed any details about the ZTE A20 5G, a renowned Chinese tipster has managed to unearth the State Radio Regulation of China (SRRC) certification listing for the device. The certification listing reveals that the device will go by the model number ZTE A2121 and it will, most likely, be a successor to the flagship ZTE Axon 10s Pro 5G (A2020 SP) which was launched earlier this year.

The publication also speculates that the ZTE A20 5G will make use of the under-screen camera solution from China-based Visionox, which started mass production of the tech last month. Visionox will also be supplying its under-screen camera tech to other Chinese OEMs like Xiaomi, OPPO, and Huawei, and we expect to see more smartphones with its under-screen camera solution in the coming months.

Vivaldi Browser on Android gets support for custom ad blocking lists and better one-handed usability

Android has no shortage of good browser options — there’s ChromeFirefoxKiwiBraveOpera and so many more that we couldn’t possibly list all of them. Most users need exactly one browser on their phone, which very likely already comes with two browsers pre-installed. Even then, having more options at hand is always a welcome move, and having more competition in the mix spurs everyone to continue innovating. Popular desktop browser Vivaldi made its way to Android last year, and over time, it has been updated with more features. The latest update to Vivaldi Browser on Android brings over support for custom ad-blocking lists and better one-handed usability.

After its release last year, Vivaldi has been updated with features like swipe to close tabs, start page customizations, DuckDuckGo’s Tracker Radar integration, and even dark mode for web content. Vivaldi v3.2 update now allows users to enable and manage several blocking lists in the Tracker and Ad Blocker, and even add their own custom lists of websites they want to block or unblock while browsing online.

The addition of blocking lists and custom lists gives users more choice in how they want their web data tracked and collected as well as the ads that are displayed. The blocking lists pre-installed within Vivaldi contains many widely used tracker URLs, and the browser stops requests to those URLs before they are sent. But users can easily enable and disable these with the settings presented. There are also country-specific listed sources, if you are looking for that. Importing and adding custom lists is also fairly simple. Further, users can also enable or disable blocking for specific websites according to their preference and manage the blocking levels per site from the Address field or the Settings.

The bottom bar on Vivaldi browser now offers more visual consistency. More options have been migrated from the top bar to the bottom bar, making it easier to use the browser one-handed. Users can now also view and switch between normal, private, synced, and close tabs from the bottom.

The Galaxy Note 20 Ultra is the first phone with Samsung’s new VRR OLED display

The Samsung Galaxy Note 20 Ultra is an incredible smartphone. While it certainly is expensive — no doubts about that — it does pack in a fair few new technologies that make it an exciting Android phone to hold in your hands, more so than the regular Galaxy Note 20. One of these new technologies is VRR, or Variable Refresh Rate, as the Galaxy Note 20 Ultra is the first smartphone to use Samsung Display’s new VRR OLED display.

Samsung Galaxy Note 20 Ultra XDA Forums

Samsung Display is announcing that the Galaxy Note 20 Ultra 5G features new display technology that allows for greater power-savings than was seen on previous commercially available flagships. This low power OLED makes use of adaptive frequency technology to reduce the display power consumption by up to 22% (though a baseline has not been specified). This adaptive frequency tech allows the display panel to utilize variable refresh rates that consume the “least possible amount of power” for each type of application. For mobile games, the display supports a 120Hz scan rate; for movie streaming, it goes down to 60Hz; emails go down to 30Hz, and viewing still images or browsing social media takes it down to 10Hz.

Samsung Galaxy Note 20 Ultra 5G (Exynos) First Impressions

High refresh rate smartphones prior to the Galaxy Note 20 Ultra used certain fixed refresh rates, meaning that they would need to stick to 60Hz, 90Hz, 120Hz or 144Hz depending on the smartphone and the setting. Companies often adapted “variable” refresh modes, but these notch down the display to a comparatively conservative 60Hz only on a per-application basis. The display would consequently either by at 60Hz always, or at a high refresh rate sometimes and 60Hz in other cases. So even though OEMs referred to these mixed modes as “variable” refresh rates, these still offered a seemingly fixed refresh rate — the panel itself could not automatically calibrate the refresh rate as it would result in noticeable image flickering because of luminance differences at the lower refresh rates. Samsung Display claims that its new backplane technology eliminates the flickering for operating frequencies as low as 10Hz, and the Galaxy Note 20 Ultra seamlessly switches between discrete 120Hz, 90Hz, 60Hz, 30Hz and 10Hz refresh rates.

While Samsung Display would suggest that this is a variable refresh rate implementation, it’s final implementation on the Note 20 Ultra isn’t exactly a true variable refresh rate as we have seen in other displays such as gaming monitors and certain TVs. Those have truly variable refresh rates within a certain range, such as 40Hz to 120Hz, letting the refresh rate match the FPS output of the GPU. However, Android does not support true VRR just yet. So even though the display would be fully capable of it, the software isn’t, and Samsung would have to resort to making very heavy modifications to enable true VRR. For now, we can stay content with more options and the resultant power savings, but it does make us very optimistic of the future.
