The screen is the most important part of your smartphone, and serves as both display and interface. Over the past decade or so, we’ve been inundated with selling points like Retina Display, 720p, 1080p, 1440p, and even 4K. The latest buzzword for screens is high dynamic range or HDR, and the latest flagship phones tout it as a must-have spec.
But what is HDR in the first place?
More colors, more brightness
Put simply, HDR lets your display exhibit a far wider range of colors. How? First, whites are whiter, and blacks are blacker. The screen does this by being much brighter than what you’re normally used to, to the tune of 1,000 nits (a unit used for display brightness). By comparison, your old flagship phone probably topped out at around 500 nits. An HDR display can also illuminate or darken specific areas of the screen, whereas a non-HDR display commonly lights the entire screen evenly.
Second is wide color gamut, or WCG. This feature increases both the color palette (the number of colors available and the bit depth (or the number of shades of those colors). Your old phone could display nearly 17 million colors. By contrast, an HDR display can show over a billion, which is much closer to what you can see in real life. When working in tandem, these two processes enable the screen to show a range of colors that are more akin to real life. This is why people who have seen an HDR display liken it to looking out a window.
But there lies the problem. The most difficult issue with conveying what HDR is exactly is that if you don’t actually have access to an HDR-capable display, it’s impossible to show the difference. Conversely, if you have an HDR display and a non-HDR display side by side, the improvements are instantly evident. This technology represents a generational leap, much like the jump from black-and-white to color, or standard definition to high definition.
A feature by any other name
You’ve probably heard the abbreviation “HDR” before as a vaunted feature for smartphones even before it was used for displays. Another source of confusion is that HDR also applies to another selling point for phones: the HDR feature of a camera. In camera HDR, the camera takes many exposures of the same scene and combines them, thereby showing all of the subtle steps in highlights and shadows.
The principle between HDR displays and photography remains roughly the same, with the end result being an image that has higher contrast and more colors. Crushed blacks and blown-out whites are also eliminated as a result. This is where the phrase “high dynamic range” comes in, representing the difference between the darkest parts of an image with the lightest.
Which gadgets have HDR?
All of this year’s important flagship phones have HDR-enabled displays, including the LG G6 and the Sony Xperia XZ Premium. However, these phones appear to be using different standards for what constitutes HDR — the LG G6 uses both the open HDR10 standard and proprietary Dolby Vision, and Sony’s 4K phone appears to be using its own definition of HDR.
Hopefully, HDR specifications normalize in subsequent generations of phones. You wouldn’t want to get a phone with HDR to find out that your HDR content won’t even display properly on it. Thankfully, at this year’s Mobile World Congress, the Ultra HD Alliance announced Mobile HDR Premium, which is an HDR standard specifically developed for smartphones, tablets, and laptops. The Samsung Galaxy S8 and S8+, two of the best phones of 2017, were the first pair to adhere to this certification.
Here are the specifics of Mobile HDR Premium for a wide variety of portable devices:
|Device||Resolution||Dynamic Range||Color Space||Bit Depth|
|Smartphones (3- to 7-inch screens)||60 pixels/degree||.0005-540 nits||90% of P3 Color gamut||10|
|Tablets (7- to 12.9-inch screens)||60 pixels/degree||.0005-540 nits||90% of P3 Color gamut||10|
|Laptops (9.5- to 18-inch screens)||60 pixels/degree||.0005-540 nits or 0.1-600 nits||90% of P3 Color gamut||10|
Why do you need HDR?
If you’re after the top-end phones, you’ll find it increasingly difficult to avoid HDR. The benefits that a more accurate display brings is most useful if you’ll be doing image work on your phone, like quickly editing photos on VSCO before sharing it to the ether. But its advantages will also be immediately noticeable if you consume content on your phone (like most people do). More and more media providers are putting out HDR content —YouTube, for one, has had HDR support since last year, and both Netflix and Amazon Video have it as well.
And with diminishing returns in terms of resolution on a five- to six-inch screen (do you really need 4K on a screen as big as your palm?), HDR is one display buzzword that is instantly apparent. Plus, unlike a 4K screen that eats batteries for breakfast, HDR on your phone can actually extend your phone’s longevity; the dynamic and selective adjustment of brightness, depending on what’s shown, should increase your screen-on time by a significant amount.

Here’s what you need to know about eSIM
The technology behind Apple’s first dual-SIM iPhone
When Apple first revealed their new iPhone XS and iPhone XS Max, people were expecting something different. While on the outside nothing seems to have changed, the inside is a whole different story. The most notable change is the introduction of eSIM (embedded SIM) technology, something that they’ve done before with the Apple Watch.
But, what is this eSIM? How different is it from the SIM card that you know and love? And does using an eSIM change the game completely?
Let’s talk about the SIM and eSIM
One of the essentials for any phone in the market is a SIM card. Short for Subscriber Identity Module, a SIM card contains key identification and security features from any network carrier. It is used by these networks to identify their consumers and provide mobile connectivity for them — through calls, texts, and access to the internet. SIM cards also allow you to store information when you decide to switch devices every now and then.
eSIM technology, as the name implies, is embedded into the phone yet it still keeps the same functionalities as before. On devices that were designed with only one SIM card slot, adding an eSIM makes it a virtual dual-SIM machine.
How have regions adopted eSIM?
As mentioned earlier, this isn’t the first time Apple dealt with eSIM tech. The company had initially launched the eSIM for their Apple Watch Series 3 to give it better connectivity on the go. While Apples continues to incorporate eSIM in its newer Watch Series 4, they’ve decided to take it one step further with the iPhone XS and iPhone XS Max.
However, as of writing, only ten countries in the entire world currently support eSIM. This is mostly due to these countries having the proper infrastructure to support the use of it. While smartphone companies are looking to incorporate this new technology, the market for it seems to be relatively small.
The good and bad about eSIM
Like any other new technology, eSIM comes with its own set of benefits and difficulties — especially for those transitioning from the traditional SIM card. With eSIM installed in your phone, users will no longer have to go through the hassle of buying a specific SIM card.
Ideally, having an eSIM also allows you to switch between networks easily. Apart from an eSIM-capable phone, it also comes with the needed software to make the switching process faster and easier. In essence, you will be able to free up the allocated SIM card slot for a physical SIM card if your device supports it. This is most helpful when you travel abroad, and you need a local number in that country to access their network.
However, there are some processes that prove to be difficult with eSIM, one of which is quickly transferring your phone number to another phone, especially if you frequently switch devices. Unlike traditional SIM cards wherein you just transfer the card, you’d have to contact your service provider to activate the number in your new phone. This could be cumbersome depending on your provider’s customer service.
Furthermore, if the eSIM in your phone becomes corrupted or gets damaged in any way, it’s possible that you would need to replace your whole phone. Because the eSIM is integrated inside your phone, it won’t be easy to pry it out when things go wrong. This wouldn’t be too big of a concern for traditional SIM cards, especially when the card gets destroyed.
Are smartphones ready for the eSIM?
The eSIM technology is still in its young stages, and only a handful of devices currently support it. There is potential for the tech to be implemented across more devices in the future despite only a few countries welcoming them. However, a lot of people still primarily utilize traditional SIM cards given the difficulties of using an eSIM.
In the case of the new iPhones, for example, you can’t create two instances of chat apps on iOS. So even if you have two numbers running at the same time, you’d need a separate phone for another WhatsApp or Viber number, until Apple comes up with a software patch for this.
In the end, the technology’s impact can only be measured once more devices embrace it. But, for now, let’s celebrate how the eSIM gave us the first dual-SIM iPhone and see where the future will take us.
All filters: Article 13 of the EUCD explained
Is this the end for memes everywhere?
If you haven’t been on the web often lately, this may be something that has slipped past your radar. On September 12, 2018, the European Parliament voted to pass a directive that could change the way we approach the internet for years to come. But, consider first that it’s only the initial review, with a final vote happening next year.
What is this directive, and why is the internet involved? Why are people suddenly seeing #Article13 trend on Twitter a few hours after the decision was passed? What’s with this #SaveTheInternet nonsense?
Understanding the copyright directive
The directive at the forefront of this entire debacle is known as the European Union Copyright Directive, or EUCD. The EUCD hopes to streamline effective regulations towards the protection of intellectual property in the EU. It was first adopted in 2001, following the ruling during the 1996 World Intellectual Property Organization Copyright Treaty. Earlier this year, another version of the directive was drafted with added articles and stipulations.
Basically, the EUCD seeks to create measures to protect one’s copyright on created content. The range of intellectual property that should be protected include music, videos, images, algorithms/codes, and even software. The directive calls for member countries to enact and implement laws that protect copyright owners. Eventually, such stipulations also reach big companies that operate within the EU.
You might be thinking why there is an outcry over it in the first place, especially when the directive’s purpose is clear. Well, there’s one particular part of the EUCD that a lot of people disagree on: Article 13.
The unlucky Article 13
Article 13 of the EUCD isn’t a lengthy piece of reading. The whole article contains three provisions for the implementation of copyright protection on websites that host user-generated content. The directive makes a note that these websites store large amounts of user-generated content, with the main purpose, if not one of its main purposes, of earning profit. Basically, any website that allows you to upload your own content and allows you to earn money from it is affected by the directive.
The article also cites that such websites should create measures such as “effective content recognition technologies,” complaint management systems, and tracking solutions. These measures should be readily available the moment users upload content on the website itself. With such measures taken into account, it allows content creators and service providers to properly engage in discussions should there be a dispute. It’s basically what YouTube Creators is all about.
Websites like YouTube, Twitch, Facebook, and Twitter, as well as streaming apps such as Spotify, Apple Music, and IGTV (when monetization is available) are most likely the article’s main targets. The directive also explicitly states that non-profit service providers and online marketplaces will not be affected. So, Wikipedia and Shopee aren’t affected, don’t worry.
The ongoing debate towards copyright protection
For some people, the EUCD is inherently good for intellectual property protection. They argue that the primary goal of the directive is to protect users from piracy and copyright infringement. Through the EUCD, there will be systems in place that protect music labels, content creators, and publishers from any illegal use of their content online. For these people, users should be held liable for infringement of any kind (memes, remixes, and parodies are a few examples).
Furthermore, the directive not only affects users but also the companies that run these websites. It basically mandates companies to create better content recognition systems, or change their already existing system for stricter copyright protection. If they don’t make adjustments, they will be held liable for any infringement-related issues. What Article 13 does, for those who are for the EUCD, is simply a suggested improvement.
However, there are others who believe that the directive is a little too extreme and could potentially do more harm than good. Leading institutions and companies in the tech industry think that the provisions are too vague, leaving it open for interpretation. This has the potential for companies to abuse copyright claims without effective ways of intervention. Furthermore, any significant changes to already-existing systems would require heavy costs to implement.
The bigger picture here is how the directive affects the internet as a whole. Big names in the tech industry argue that it’s an attack on the creative freedom of users. Instead of allowing the internet to be an open space for the right way of creativity, it simply adds more filters and restrictions in the process. Basically, you can’t put up an Avengers meme without having the approval of Disney and Marvel Studios first.
So, what happens now?
The EUCD was put in place to protect copyright — a simple and basic goal. There is recognition that there are measures that must be in place to uphold copyright. There is no denying that big companies have to abide by intellectual property rules, or suffer severe consequences for infringement. However, a lot of people are clamoring that these measures are both vague and sound extreme. Not only does the directive infringe one’s creative freedom in providing quality content, but it also makes the whole process costly and rigid.
At the end of the day, everybody wants to protect copyright. The argument for or against the EUCD is already past the debate on whether protecting copyright is right or wrong. The debate now is whether or not a open source like the internet should be kept that way or be strictly protected at all costs.
All of these will come into play in January 2019, when the European Parliament casts its vote for or against the directive. If you have the time to read the EUCD, you can access the full document here.
Play more, charge less: Huawei’s GPU Turbo explained
Better visuals without sacrificing battery life?
Aside from using your phone to call, text, and take pictures, you now have the power to access the internet and play games with others. Instead of limiting yourself to Snake and Bounce, you now have online games such as PUBG Mobile and Mobile Legends.
There’s just one problem: Not all games are playable across all smartphones. With the gaming world now expanding to the mobile scene, you would need a smartphone with the latest hardware and software inside it. Even if that’s not the case, you would need a smartphone that can handle long hours of gaming, as well. It’s an intense fight over what matters to you the most: performance versus efficiency.
Fortunately, the choice shouldn’t be very difficult thanks to Huawei’s latest mobile advancement: GPU Turbo.
What’s GPU Turbo all about?
GPU Turbo processing technology aims to enhance the gaming experience across Huawei’s smartphones. Executives promise that the tech will boost gaming performance while maintaining the phone’s efficiency. This means you can play games on your smartphone without sacrificing much — like battery life, for example.
The technology looks at the graphical capabilities of your phone and adjusts it accordingly, especially for gaming. With GPU Turbo, technologies such as 4D gaming and both augmented and virtual reality (AR and VR) are taken care of. Huawei believes that GPU Turbo will boost graphical performance by 60 percent, and can make even budget phones play graphically intensive games.
Apart from boosting visual performance, GPU Turbo also enables smartphones to maximize efficiency. One common problem across all smartphones is that the battery depletes relatively fast while you’re gaming. Partner that with a non-effective cooling solution within the phone, and it’s basically device overkill when playing games. What GPU Turbo does is extend your phone’s battery life by 30 percent and keep your device relatively cool while playing.
Implications on Huawei Smartphones
One of the key insights Huawei executives received was about consumer demand for a smoother mobile gaming experience. Because people want to play the latest mobile games seamlessly, they would want to buy smartphones that are capable of doing so. Graphical performance should not suffer in the slightest, especially for multiplayer online battle arena (MOBA) and battle royale games.
The fun doesn’t stop there: With Huawei smartphones supporting GPU Turbo, other technologies such as AR and VR get a chance to truly shine. Huawei executives claim that GPU Turbo opens up opportunities for innovations like online shopping through AR or telemedicine through VR. At this rate, in theory, you could have a truly complete smartphone experience on your hands.
As of writing, GPU Turbo will take effect Huawei’s latest smartphones like the new Huawei Nova 3 series. However, older smartphones supported by the latest EMUI will experience the upgrade, as well. (View the list here.)
If you’ve been dying to have the full mobile gaming experience, GPU Turbo is definitely something to watch out for.
