News: Samsung's Galaxy S9 Could Arrive in a Burgundy Red Color

Samsung just announced that the Galaxy S8 is getting a fresh coat of paint, launching a burgundy red color of the flagship in their home market of Korea. There is currently little information about whether this color will come to the US for the S8, but this could be a preview of things to come. The Galaxy S9 is set to arrive in January and may also come in a beautiful red variant.

How To: Disable the Always-on Ambient Display on Your Pixel 2 or Pixel 2 XL

Unlike traditional backlit LCD technology, OLED screens don't use any power to display black pixels. Many manufacturers have taken advantage of this by implementing an always-on display, which only lights up a few pixels here and there to show relevant info when your phone is locked. But this leads to extra battery drain, albeit small, and it increases the risk of screen burn-in.

How To: Get Back the Camera's Missing HDR Button on Your iPhone 8 or 8 Plus

Out of the box, when you shoot a photo on your iPhone using the stock Camera app, it will either shoot a normal or HDR photo. That's because Apple's high-dynamic-range setting is set to automatic by default. However, there's a button in the app so you can turn HDR on or off manually. While this HDR toggle persists in iOS 11 on the iPhone 7 models and older, it's not visible on the iPhone 8 or 8 Plus.

Kodi 101: How to Change the Default Skin for a Fresh New Theme

When you first use Kodi, it can be intimidating. The main menu has numerous options for the various types of media Kodi can play back, and the settings menu has a broad array of tools to customize Kodi to your needs. After poking around in theses menus, you might realize that you don't like the default look. But whether it's the color, font, layout, or just the general theme, Kodi skins can change it all.

How To: Format WhatsApp Messages with Italic, Bold, Strikethrough, or Monospaced Text

Unless you're a WhatsApp pro user, you may be surprised to know that there are text formatting options that you can apply to your messages. Markdown characters can help you emphasize certain words or phrases by making them italicized or bold, and it'll even let you cross out words and change the font. It's one of those nice touches that isn't available in most other messaging apps.

How To: Disable Notification Previews for All Apps in iOS 11

I couldn't live without seeing previews of certain notifications on my iPhone, but there are definitely some that I'd like to hide, either because they're annoying or because I don't want anyone else to see them. Previously, you could only disable notification previews for Apple apps such as Mail, Messages, Photos, and Wallet, but in iOS 11, you can disable previews for every single app on your iPhone.

How To: Add or Remove Email Addresses to Be Reached At for FaceTime on Your iPhone

On your iPhone, your phone number and Apple ID email address are the default ways in which somebody can contact you on FaceTime. While you can't remove your phone number as an option, you can withdraw your Apple ID email account. More importantly, you can add any other email addresses you'd like to the list, so you never have to worry about a friend, family member, or coworker not being able to audio or video chat with you.

How To: Wallet Not Showing on Your Lock Screen? Here's How You Really Access Passes Quickly on Your iPhone

I haven't bought into Apple Pay just yet, but I do love the idea of having quick access to passes like loyalty programs, boarding passes, and my Starbucks card. However, for some users, it's impossible to open these passes stored in Apple Wallet on the iPhone's lock screen. While it's not totally obvious, or even ideal, there is a way to get those Wallet passes back on your lock screen in iOS 9 or iOS 10.

How To: Secure Your Instagram Account by Adding 2-Factor Authentication & Managing Privacy Settings

The photo-centric Instagram app is a great way to share "evergreen" pictures and videos when compared to Snapchat and Facebook's new Messenger Day feature. But like all social media, keeping the account secure is an essential aspect, as it restricts unwanted viewers from seeing your content and can prevent unauthorized users from accessing your account. Instagram has several methods for locking down the account including a new two-factor authentication (2FA) mechanism.

How To: Add a Number Row to Google's Gboard Keyboard

Google's Gboard is by far the most popular keyboard available right now. Gboard lets you search almost anything—from regular Google searches, to emojis, and even GIFs—just by using your keyboard. The app even lets you share search results, saving you a great deal of time, which would've otherwise been spent juggling between apps and programs.

How To: Stop Sites from Tracking You on Your iPhone with Firefox Focus

When you do an internet search, you'll see ads that are relevant to your query mixed in with the rest of your results. Nothing surprising there—it's how the internet is funded. But then, when you click one of the search results, you'll also see ads that are related to your initial search. Now that's a bit creepy, because it demonstrates that one webpage knows what you typed into a different webpage.

How To: Remove Widgets from Your iPhone's Lock Screen

Widgets are great ... if you actually use them. A quick swipe right on the lock screen will reveal the Today view and its widgets, and it's very easy to accidentally open. Plus, others can see your widgets without any authentication. You could manually remove every widget, but that wouldn't prevent the right-swipe from opening the Today view. There is a way, however, to disable the page entirely.

How To: Get 'Hey Siri' Working Again on Your iPhone

When Hey Siri was first introduced in iOS 8, it was a pretty lackluster feature since you had to be plugged into a power source in order to even use it. Since then, newer devices (iPhone 6s, 6s Plus, SE, 9.7-inch iPad Pro) don't need to plug in to have always-on Siri, which makes the feature actually worthwhile—when it works.

How To: Android Nougat's Quick Reply Feature Already Looks Dated Next to This App

When Android Nougat is released sometime this fall (or sooner), a new feature called "Quick Reply" will allow users to respond to incoming text messages directly from the notification. It will definitely be nice to carry on a conversation without leaving the screen you're currently viewing, but unfortunately, most of us won't get that Android Nougat update for quite some time.

News: New Siri Bug Lets Anyone Bypass Your Lock Screen to See Photos & Contacts

A new iPhone exploit has recently been discovered by YouTube user videosdebarraquito, who has found many other exploits and bugs in iOS over the years. This new exploit allows someone to bypass the lock screen and gain access to contacts and photos via Siri, Apple's digital voice assistant—but it only affects the iPhone 6s and the iPhone 6s Plus because it requires 3D Touch functionality.

How To: Get Rid of Microsoft's Annoying Ads on the Windows 10 Lock Screen

For the past three or four months, Microsoft has been pushing advertisements onto the lock screens of some Windows 10 users as part of its "Windows Spotlight" feature. This feature normally shows you scenic photographs and gives you the option to learn more about them by launching an Edge window once you log in. However, the aforementioned users have reported seeing the image below for the new Rise of the Tomb Raider game. Rather than taking you online in Edge to learn about it, you're given ...

Dissecting Nmap: Part 1

Welcome aboard my inquisitive comrades. I am starting a new series that nobody expected coming. It may not seem very exciting at first, but await the last few parts as many startling discoveries will be made. This is a series which I plan to continue after the completion of Nmap, unless you have major objections.
