How To: The Easiest Way to Unlock the Bootloader on Your HTC EVO 4G LTE or Other HTC Smartphone

Nearly two years ago, Peter Chou, CEO of HTC, confirmed that the company would no longer be locking bootloaders. Whether or not they've actually lived up to this claim is debatable. Any phone bought from a wireless carrier comes locked. Only the new HTC One Developer Edition ships with an unlocked bootloader, and it does not have any carrier add-on software installed.

How To: Hack Your Old Phone Line into an Emergency Power Supply for Your Cell Phone

"Ahoy-hoy." If telephone titan Alexander Graham Bell had his way, we'd all be answering phones like Mr. Burns. Thankfully, frienemy Thomas Edison had enough sense to realize we weren't always on the briny. He preferred "hello" as our standard telephone greeting, which he is credited with coining in 1877. Fellow American pioneer Davy Crockett actually used it as a greeting first in 1833 (as compared to an exclamation)—but in print, not over the phone.

How To: Squeeze Blazing Fast Speeds Out of Your Samsung Galaxy S4

We've already covered how to remove the Home button lag on the Samsung Galaxy S4, now let's take a look at how to speed up a few more key areas on your new device. This GS4 is already blazing fast, but let's squeeze every ounce of speed we can from it by making a few basic tweaks. This is a really simple hack, and all you'll need is to have Developer Options enabled.

How To: Fix the Home Button Lag on Your Samsung Galaxy S4

Your new Samsung Galaxy S4 is fast, but it can definitely be faster. One issue that carried over from the Samsung Galaxy S3 is Home button lag. Instead of it being an instantaneous response, it takes a split second for the action to take place—and a split second is enough to irritate the best of us. The culprit here is S Voice. The built-in voice assistant is great, but whether or not you use it, one of its features remains persistent—its strenuous use of the Home button—where you double-tap ...

How To: 10 Unique & Practical Ways to Repurpose Your Old Hard Disk Drives

At one point in the '90s, about fifty percent of the CDs produced worldwide had an AOL logo. About fifty percent of the CDs in my home still have that AOL promise of 500 free hours on them. Though they never got me to join their internet service, I did get a lifetime supply of coasters. Thanks to the rise of high-speed internet access and bigger and better hard drives, there's no reason for companies to snail mail any more of those obnoxious plastic discs.

How To: Restore an iPod Touch Without Using iTunes

The iPod changed the music and electronics industries when it was first introduced way back in 2001. It is credited with ushering in the age of "connected devices," and has held a huge market share of around 70% for years. At the height of its popularity, the iPod made up almost 50% of Apple's revenue. Now that the smartphones and tablets we use every day have the ability to store and play music, the iPod's glory days are over. Nevertheless, there are millions of people who still use them, an...

How To: Connect Your iPhone, iPad, or iPod Touch to Your TV for the Ultimate Viewing Experience

As we all use our smartphones for more and more things, we constantly want to share and view those items on a larger screen, especially when it comes to media. While phones like the Samsung Galaxy Note 2 and tablets like the iPad do make watching Netflix on a portable device pretty legit, bigger is always better. Newer iPhones may have Retina displays, but watching Avatar on your phone is like being forced to drink a delicious mango tango smoothie with a coffee straw. Plus, if you want to sho...

How To: DC Versus AC and the Diode

Direct current (DC) by definition flows in one direction. Alternating current (AC), on the other hand, periodically changes direction, or reverses polarity. It is indeed possible for a portion of a circuit that is normally DC to periodically change direction, or reverse polarity like an AC circuit.

How To: Root Your Brand Spanking New Samsung Galaxy S4

If you pre-ordered your Samsung Galaxy S4, it might very well be possible that you're reading this on your brand spanking new Android device. As is commonplace with the release of popular smartphones, rooting instructions are usually released simultaneously. I mean, what's the point of paying so much for an expensive phone if you can't have a little fun? Android developer Dan Rosenberg (aka djrbliss) recently announced that you can root your Samsung Galaxy S4 using the root exploit he origina...

How To: Improve Battery Life on Your Nexus 7 Tablet with This Easy Power-Saving Tweak

Like most Android devices, the Nexus 7 suffers from its fair share of battery gripes. Nobody wants to see that dreaded "connect charger" warning pop up on their screen. NOBODY. Yet it probably happens to you every day nonetheless. What can you do about it besides charge, charge, and charge? Well, there's actually plenty that you can do. You can manage your notifications better, keep your screen brightness low, and kill apps running in the background. Or, you could just optimize your battery t...

How To: Get Beats Audio on Your Nexus 7 and Take Your Music to Another Level

BEATS by Dr. Dre started making their studio-style headphones and speakers over four years ago, which claim to help listeners actually "hear" music as it was intended by the artists, since commodity headphones and earbuds are known for producing lackluster results. But you can only go so far with Beats Audio headphones, since your computers and mobile devices weren't built to take advantage of high quality audio equipment.

How To: Get Rounded Screen Corners on Your Samsung Galaxy S3 or Other Android Device

Tired of your Samsung Galaxy S3 being a square? Make it more well-rounded by ditching those 90-degree corners on your screen for new adjustable round corners instead. It may be a minor tweak to your device, but the psychological effects of a more circular screen may help you feel more connected, safe, and, well…perfect. If you're the type that prefers the logic, order, and security of a sharp-cornered screen, then stick with your standard Android interface. Otherwise, keeping reading.
