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.

How To: The 5 Best Phones for Video Chat

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.

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: 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."

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.

Cyanogen, Inc., the for-profit company that spun off from its CyanogenMod roots several years ago, has announced that they're shutting down all of their services.

How To: Track Lyft & Uber at the Same Time to Avoid Surge Pricing & Select Faster Rides

With the exception of New York, D.C., and maybe San Francisco, public transportation in the United States is downright abysmal. Like it or not, you need a car to get around. This is why Uber and Lyft have seen so much success in recent years. Both ride-sharing services get you from point A to point B in an efficient manner, and they do it without costing an arm and a leg. Well, in most cases.

Dutch filmmaker Anthony Van der Meer published his 2015 thesis short from Willem de Kooning Academy in South Holland online in December 2016. It's a brilliant piece of work that managed to be touching, alarming, and informative at the same time. His documentary, which already has over 6 million views on YouTube, covered the journey made by a stolen smartphone and how the theft and ensuing tracking affected all parties involved.

How To: Play Almost Any PSP Game on Your Android Phone

If you really want to play Gran Turismo or Castlevania on the go, Sony's PlayStation Portable is a great way to do it. But it gets harder and harder to justify carrying around a PSP handheld gaming console when you've got an equally powerful Android phone in your pocket already. The PSP had a good 10 years before being discontinued, and your Android can pick up the slack now.
