How To: Save Battery When Playing YouTube Music on Your Galaxy, Pixel, or Other AMOLED Device

If your phone has an AMOLED display, it doesn't waste any battery to power black portions of the screen. This is because the individual pixels that make up an AMOLED screen emit their own light, which means the backlight you'd find behind a traditional LCD screen is not present. In other words, showing a full-screen black image on an AMOLED phone is like turning your display completely off.

How To: Get the Pixel's Solid Nav Bar Buttons (Or Color Yours In) on Other Phones — No Root Needed

Google's own devices have always been the first to get new Android features — but unlike the Nexus series, last year's Pixel phones have a handful of exclusive tweaks that were never intended to trickle down to other devices once the newer Android version rolled out to them. These Pixel exclusives included the Pixel launcher and a unique set of on-screen navigation buttons.

How To: Get Rid of the Built-in Google Search Bar on Almost Any Launcher

Almost every Android device comes with a Google search bar embedded directly into its stock home screen app. But Google search is available in so many different places on Android that having this bar in your launcher is almost overkill. On top of that, Google recently changed the logo overlay to a more colorful one that may clash with your home screen theme, so there's plenty of reasons to dislike this feature.

How To: Get CyanogenMod's 'Caffeine' Feature to Keep Your Screen Awake Longer at the Press of a Button

Sometimes it's the smallest feature in your smartphone that makes the biggest difference in user experience. Take screen timeout, for instance. You can probably think of plenty of times when your handset's display blacked out while you were in the middle of something. You could have been cooking with a recipe on the screen or looking at chords while you learned a new riff on your guitar.

How To: Get Nintendo's Fire Emblem Heroes Game on Your Android Phone Right Now

Nintendo's first ever game for Android has finally touched down (unless you actually count the abomination that is Miitomo). Fire Emblem Heroes, a classic turn-based RPG optimized for mobile gaming, has come out for Android and iOS in Australia, Europe, and Japan, and is due out in North America and other worldwide locales very soon. Due to Nintendo's staggered release, the game isn't available to us in the United States at the time of this writing, but fret not—there's another way to downloa...

How To: Set Default Volume Levels for Each of Your Bluetooth Accessories Individually

If you have multiple Bluetooth accessories, Android's volume system can be pretty annoying. For one thing, most phones reset to a "Safe Volume Level" every time you reconnect a pair of headphones, which means you'll probably need to turn up the volume once or twice a day. But even if your phone doesn't exhibit this obnoxious behavior, you might want your car's Bluetooth connection to be louder than, say, your home stereo or your wireless earbuds.

HoloLens Dev 102: How to Add Holographic Effects to Your Vuforia ImageTarget

Welcome back to this series on making physical objects come to life on HoloLens with Vuforia. Now that we've set up Vuforia and readied our ImageTarget and camera system, we can see our work come to life. Because in the end, is that not one of the main driving forces when developing—that Frankenstein-like sensation of bringing something to life that was not there before?

HoloLens Dev 102: How to Create an ImageTarget with Vuforia & Set Up the Camera System

Now that we've set up Vuforia in Unity, we can work on the more exciting aspects of making physical objects come to life on the HoloLens. In this guide, we will choose an image (something that you physically have in your home), build our ImageTarget database, and then set up our Unity camera to be able to recognize the chosen image so that it can overlay the 3D holographic effect on top of it.

How To: The 5 Best Phones for Video Chat

Video chatting has become an important factor in the overall smartphone experience. Even just a few years ago, 37% of teens were making video calls on a regular basis, and that number has surely grown. 85% of households with infants have used video chat apps to call relatives in other cities, and it's been shown that toddlers can create bonds and learn from visual cues in video calls.

How To: Install Kodi on Your iPhone Without Jailbreaking

Kodi, formerly known as XBMC, is one of the most versatile media players available. With it, you can play virtually any internet and media file in a large variety of formats, and it can be used on practically every single operating system out there, including iOS 10. Kodi, an open-source software, was originally designed to connect to your TV so you could control your media from up to ten feet away, and the core functionality still shines today. All of this is what makes Kodi so popular today...

How To: Protect Individual Apps on Android That You Can Only Unlock with Your Face

Locking individual apps on your Android device gives you an added layer of security by safeguarding app data from unwanted attention. I personally prefer using an app locker over a standard lock screen because my kids play with my phone, and they've completely disabled it after inputting the wrong PIN. So app lockers give me the right balance between giving my children access to my device, and the security of locking down my data from would-be intruders.

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: Automatically Launch Two Apps at the Same Time in Android's Multi-Window Mode

Android 7.0 Nougat brought a lot of multitasking improvements along with it, but the most notable addition is a unified multi-window mode (which shines bright in Google's Pixel phones). This means that every Android device can now use the same split-screen interface, and the days of software fragmentation caused by differing multi-window implementations by LG and Samsung are now over.

How To: The Best Apps to Help You Quit Smoking

There's an adage that says "Every plan, no matter how great, goes out the window as soon as you're punched in the face." While our lives are (hopefully) not violent, that saying can easily translate to our daily living. That punch in the face can come in various forms, mainly stress-related. It could be a bad day in the office, rush hour traffic, drama in the family, the list goes on.

How To: 3 Apps for Getting Your Budget & Finances Under Control in 2017

It's become a routine for many of us to ring in the New Year with pledges to finally get our budgets and finances under control. Unfortunately, it's also quite difficult to to keep those promises. Some of us will just dive into our resolutions and wing it as we move forward, which usually ends in failure. But even for those of us who plan carefully, obstacles along the way can spell doom for New Year's resolutions.
