Samsung A51: Saviour of the mid-range

For a few years, Samsung has delivered some less than favourable mid-range devices compared to the competition. The Galaxy A51 is here to change all that, writes BRYAN TURNER.

It’s not often one can look at a mid-range phone and mistake it for a flagship. That’s what you can expect to experience when taking the Galaxy A51 out into the open.

Samsung went back to the drawing board with its new range of devices, and it shows. The latest Galaxy A range features some of the highest quality, budget-friendly devices we’ve seen so far. The Samsung Galaxy A51 is one of the best phones we’ve seen in a while, not just aesthetically, but in what it packs into a sub-R7000 price tag.

Looking at the device briefly, it’s very easy to mistake it for a flagship. It features a four-camera array on the back, and an Infinity-O punch-hole display – both of which are features of the high-end Samsung devices. In fact, it features a similar camera array as the Galaxy Note10 Lite but features an additional lens in the array. The cameras line up in an L-shape, clearly avoiding looking like a stovetop.

Apart from the camera array, the back of the handset features a striking pattern called Prism Crush, a pattern of pastel shades that come in black, white, blue, and pink. For the review, we used the Prism Crush Blue colour and it looks really great. The feel is clearly plastic, which isn’t too surprising for a mid-range device, but the design is definitely something that will make users opt for a clear case. It’s also great to see a design pattern that deviates from the standard single iridescent colours many manufacturers have copied from Huawei’s design.

Along the sides, it features a metal-like frame, but again, it’s plastic. On the left side, we find a SIM and microSD card tray while the right side houses the power button and volume rocker. The bottom of the phone features a very welcome USB Type-C port and a 3.5mm headphone jack, which isn’t too uncommon for mid-range phones.

On the front, the device is pretty much all screen, at an 87.4% screen-to-body ratio, thanks to a tiny chin at the bottom and the small punch hole for the camera. The earpiece has also been hidden inside the frame in attempts to maximise this screen-to-body ratio. When powered on, the 6.5-inch display looks vivid and sharp. That’s because Samsung opted to put a Super AMOLED display into this midrange unit, giving it a resolution of 1080 x 2400 (at 405 ppi) in a 20:9 format. This makes the display FullHD+, and perfect for consuming video content like Netflix and YouTube in HD.

Hidden underneath the display is an in-screen fingerprint sensor, which is very surprising to find in a mid-range device. While it is extremely accurate, it takes some getting used to because the sensor is so large that one needs to put one’s entire finger over the right part of the display to unlock it. Most other types of non-in-screen fingerprint sensors don’t mind a partial fingerprint. The display itself feels nothing like the back and that’s because it’s not plastic, but rather Gorilla Glass 3, to prevent the screen from shattering easily.

What’s interesting about this device is finding accessories which aren’t quite available in phone stores yet. When browsing online for screen protectors, one has to be on the lookout for screen protectors that are compatible with the in-screen fingerprint sensor. Make sure to check out the reviews of users before purchasing them.

In terms of software, Samsung has made a great deal of effort to make the experience slick. Gone are the days of TouchWiz (thank goodness) and now we have OneUI in its second version. OneUI makes the phone easier to use by putting most of the interaction on the bottom half of the screen and most of the view on the top part of the screen, where one’s thumbs don’t usually reach.

Out of the box, the device came with Android 10. This is a huge step forward in terms of commitment to running the latest software for major feature updates as well as for Android security patches to keep the device secure.

It also has most of the cool features from the flagship devices, like Samsung Pay, Bixby, and Link to Windows. Samsung Pay is an absolute pleasure to use, even if it still confuses the person taking your payments. From linking my cards, I have stopped taking my wallet out with me because all merchants that accept tap-to-pay will accept Samsung Pay on the A51.

Bixby is useful if you’re in the Samsung app ecosystem, especially for owners of SmartThings devices like Samsung TVs and SmartThings-enabled smart home devices. Otherwise, Google Assistant is still accessible for those who still want to use the standard Google experience.

Link to Windows is an interesting feature that started with the Galaxy Note10 and has since trickled down into the mid-range. It allows users to send SMS messages, view recently taken photos, and receive notifications from the phone, all on a Windows 10 PC. This can be enabled by going to the Your Phone app found in the start menu.

The rear camera is phenomenal for a mid-range device and features a 48MP wide sensor. The photos come out as 12MP images, which is a common trick of many manufacturers to achieve high-quality photography. It does this by combining 4 pixels into a single superpixel to get the best colours out of the picture, while still remaining sharp. It also performs surprisingly well in low light, which is not something we were expecting from a mid-range device.

The 12MP ultra-wide angle lens spans 123-degrees, which is very wide and also useful for getting shots in where one can’t move back further. It’s not as great as the main lens but does the trick for getting everyone in for a group photo in a galley kitchen.

The 5MP depth-sensing lens supplements the portrait mode, which adds a blur effect to the background of the photo – the same lens as its predecessor, the Galaxy A50. It features a 32MP wide-angle selfie camera, which is perfect for fitting everyone into a large group selfie.

The processor is an Exynos 9611, which is an Octa-core processor. It performs well in most situations, and there is software built in to give games a boost, so it performs well with graphically intensive games too. In terms of RAM, there are 4GB, 6GB, and 8GB variants, so keep an eye out for which one you are trying. For the review, we had the 4GB, and it performs well with multitasking and day-to-day tasks.

For storage, it comes in a 128GB model on Samsung’s website, which seems to be the standard size. This is extremely welcome in the mid-range segment and is the largest we’ve seen for internal storage capacity as a starting point.

At a recommended selling price of R6,999, the Samsung Galaxy A51 marks the beginning of a great era for Samsung, because it provides a feature-rich handset at an affordable price.

IoT sensors are anything from doctor to canary in mines

Industrial IoT is changing the shape of the mining industry and the intelligence of the devices that drive it

Published

on

The Internet of Things (IoT) has become many things in the mining industry. A canary that uses sensors to monitor underground air quality, a medic that monitors healthcare, a security guard that’s constantly on guard, and underground mobile vehicle control. It has evolved from the simple connectivity of essential sensors to devices into an ecosystem of indispensable tools and solutions that redefine how mining manages people, productivity and compliance. According to Karien Bornheim, CEO of Footprint Africa Business Solutions (FABS), IoT offers an integrated business solution that can deliver long-term, strategic benefits to the mining industry.

“To fully harness the business potential of IoT, the mining sector has to understand precisely how it can add value,” she adds. “IoT needs to be implemented across the entire value chain in order to deliver fully optimised, relevant and turnkey operational solutions. It doesn’t matter how large the project is, or how complex, what matters is that it is done in line with business strategy and with a clear focus.”

Over the past few years, mining organisations have deployed emerging technologies to help bolster flagging profits, manage increasingly weighty compliance requirements, and reduce overheads. These technologies are finding a foothold in an industry that faces far more complexities around employee wellbeing and safety than many others, and that juggles numerous moving parts to achieve output and performance on a par with competitive standards. Already, these technologies have allowed mines to fundamentally change worker safety protocols and improve working conditions. They have also provided mining companies with the ability to embed solutions into legacy platforms, allowing for sensors and IoT to pull them into a connected net that delivers results.

“The key to achieving results with any IoT or technology project is to partner with service providers, not just shove solutions into identified gaps,” says Bornheim. “You need to start in the conceptual stage and move through the pre-feasibility and bankable feasibility stages before you start the implementation. Work with trained and qualified chemical, metallurgical, mechanical, electrical, instrumentation and structural engineers that form a team led by a qualified engineering lead with experience in project management. This is the only way to ensure that every aspect of the project is aligned with the industry and its highly demanding specifications.”

Mining not only has complexities in compliance and health and safety, but the market has become saturated, difficult and mercurial. For organisations to thrive, they must find new revenue streams and innovate the ways in which they do business. This is where the data delivered by IoT sensors and devices can really transform the bottom line. If translated, analysed and used correctly, the data can provide insights that allow for the executive to make informed decisions about sites, investment and potential.


“The cross-pollination of different data sets from across different sites can help shift dynamics in plant operation and maintenance, in the execution of specific tasks, and so much more,” says Bornheim. “In addition, with sensors and connected devices and systems, mining operations can be managed intelligently to ensure the best results from equipment and people.”

The connection of the physical world to the digital is not new. Many of the applications currently being used or presented to the mining industry are not new either. What’s new is how these solutions are being implemented and the ways in which they are defined. It’s more than sticking on sensors. It’s using these sensors to streamline business across buildings, roads, vehicles, equipment, and sites. These sensors and the ways in which they are used or where they are installed can be customised to suit specific business requirements.

“With qualified electronic engineers and software experts, you can design a vast array of solutions to meet the real needs of your business,” says Bornheim. “Our engineers can programme, create, migrate and integrate embedded IoT solutions for microcontrollers, sensors, and processors. They can also develop intuitive dashboards and human-machine interfaces for IoT and machine-to-machine (M2M) devices to manage the input and output of a wide range of functionalities.”

The benefits of IoT lie in its ubiquity. It can be used in tandem with artificial intelligence or machine learning systems to enhance analytics, improve the automation of basic processes and monitor systems and equipment for faults. It can be used alongside M2M applications to enhance the results and the outcomes of the systems and their roles. And it can be used to improve collaboration and communication between man, machine and mine.

“You can use IoT platforms to visualise mission-critical data for device monitoring, remote control, alerts, security management, health and safety and healthcare,” concludes Bornheim. “The sky is genuinely the limit, especially now that the cost of sensors has come down and the intelligence of solutions and applications has gone up. From real-time insights to hands-on security and safety alerts to data that changes business direction and focus, IoT brings a myriad of benefits to the table.”
