As Android owners, we ultimately have to look at our device and ask the difficult question: "Where the hell did all these applications come from?" We're all guilty of installing the latest and greatest app or game, but at some point we come to the realization that we're digit ...more
Waking up to hundreds of text messages in the morning usually points to one thing—group messages. Whether it's your fantasy football league, your work buddies, or just a bunch of bored friends, group messages can leave your iPhone vibrating off the hook. If the group message ...more
Your iPhone comes packed with a long list of excellent text tones to choose from. Bamboo anyone? Of course, for some of us, stock sounds from 2013 don't cut it anymore. We want customizability, something that's found more on Android than iOS. However, you can add your very own ...more
Your iPhone's built-in Voice Memos app is a great way to record the audio around you, whether it be conversations, lectures, meetings, interviews, discussions, chitchat, gossip, or other kinds of talks. But if your goal is to record audio on the down-low without being noticed, ...more

To some, SCRABBLE is just a board game to play during family game night or during a casual get-together. Others think of SCRABBLE as a mere hobby. But with any activity, there will always be fanatics—the ones who would rather sell their soul than stop—the ones with a constant ...more

When you tap on a URL link in a text, email, or wherever, your iPhone's default reaction will be to open it up in Safari, and there's no way to change this in the settings. However, there is a way you can work around this to open up links in Chrome instead. Even if you acciden ...more
Many Android utilities use Android Debug Bridge, or ADB for short, to send commands from a computer over to your phone or tablet. This enables such utilities to run terminal commands that, in some cases, wouldn't be possible on Android without root access. Before getting star ...more
As mentioned before, the Home button is one of the most important keys on your Samsung Galaxy S3, and pretty much all Android devices for that matter. However, when it comes to customization, it's rather tame. If you've ever used Activator on a jailbroken iPhone, you know the ...more
While iOS offers a plentiful mix of excellent and exclusive features, what you see is what you get. Apple doesn't leave much room for customizability, meaning most people's iPhones look relatively the same. You can make yours stand out, however, by giving your apps unique and ...more
We're nearly done getting our Mac set up for hacking. If you haven't checked out previous tutorials, I'd recommend you do so first before diving right into this one. While macOS is a powerful POSIX-compliant operating system, some of our Linux tools do not work out of the box ...more
A custom recovery is a very powerful tool. You can flash ZIPs that modify your Android device in ways that not even root can accomplish, and of course you can use it to install custom ROMs. But when you're applying all of these cool mods, there's always a chance that something ...more
You've unlocked your bootloader and rooted your HTC One running KitKat, but there's still one lingering aspect of security you've yet to rid yourself of—S-On—the extra security measure HTC implemented into Sense. S-Off stands for Security Off and allows you to update your One ...more
When it comes to modding Android, root gets all the glory, but a good custom recovery is really the only thing you need. Not only does it allow you to back up your entire phone, install flashable ZIPs, and load custom ROMs like LineageOS, but a custom recovery will even let yo ...more

In general, smartphones and cars don't mix—but this is mainly because you have to take your eyes off the road to poke around on your handheld gadget. In reality, the only difference between your smartphone and your car's FHWA-approved infotainment system is that the latter is ...more
Update: June 19, 2014 Android 4.4.4 has been released, fixing a small security bug in 4.4.3. The factory images have already been made available to all current-generation Nexus devices, and I've linked them out below. This does not affect the process depicted, you can still u ...more
Apple's line of iPhones, iPads, and iPods are of some of the most advanced devices available on the market. Usually, the biggest complaint is that they are not customizable, but they can be if you exploit a few bugs in the system. Here lie the instructions that turn an iOS 7 ...more
The price of hacking Wi-Fi has fallen dramatically, and low-cost microcontrollers are increasingly being turned into cheap yet powerful hacking tools. One of the most popular is the ESP8266, an Arduino-programmable chip on which the Wi-Fi Deauther project is based. On this ine ...more
If I were to lose access to the entire internet for the rest of my life, one of the websites I would miss the most would have to be Wikipedia. Wikipedia has ended countless arguments, informed me of how old and single some of my favorite actresses are, and helped me brush up o ...more
Apple just released its iOS 16.6 update for iPhone on July 24. When you install the new software, it may look like there's not much to it since Apple doesn't include any features in the release notes beyond "important bug fixes and security updates," but a few new features are ...more
There really isn't any custom manufacturer skin, like Sense, that can match the clean look and fluidity that comes with stock Android. HTC knows this, and they, just like Samsung, include a Google Play Edition version in their flagship lineup. In effect, these GPE variants pu ...more
On the internet, everything is possible, even if it's not grounded in reality (check no further than anything The Onion publishes). Witty headlines combined with clever photo edits make even the most absurd topic seem like a serious news story. Some of these stories are so con ...more

In Apple Music, loving and disliking songs is a great way to teach Apple's subscription service what type of tunes you like and which you don't. While it also seems like it should be an excellent way to keep track of songs you enjoy in the wild, there's no clear way to view al ...more
Starting with Marshmallow, Android added a built-in theme engine called "Runtime Resource Overlay," or RRO. This theme engine was intended to be used only by smartphone manufacturers, not end-users, so unlike Cyanogen's CM Theme Engine, owners can't use it to change the look a ...more
Navigating and editing text is an essential part of any operating system, and with iOS 13, Apple has made some significant changes. Some things remain the same when working with text, but there are many updates to moving the cursor, scrolling, and selecting, cutting, copying, ...more
It may not be as large as the Samsung Galaxy Note 2, but the Galaxy S3's screen size is still big enough to make iPhone owners cry themselves to sleep. The 4.8-inch AMOLED display with 720 x 1280 pixels makes the GS3 a great mobile companion—and an even better portable gaming ...more
There are many different reasons that you might want to revert your Samsung Galaxy S5 back to stock. The main one would probably be that you need to return your device to the manufacturer for warranty purposes. And if you've used root to modify system-level files and component ...more
Microsoft has invested years and countless man-hours in an effort to get their cloud storage service on par with competitors like Dropbox and Google Drive, who have long resided at the top of this market. Their hard work has definitely paid off, as OneDrive (formerly SkyDrive) ...more

Organizing contacts is a bitch, especially on the iPhone. Some contacts will have multiple entries, you can only delete contacts one by one, and certain types of contacts can't be deleted at all. If that isn't enough to make you pull your hair out, then I don't know what will. ...more
Keeping unwanted clowns off on my Samsung Galaxy S3 is priority number one. I've shown you how to snag a picture of people opening your apps and how to lock your screen for whenever you hand off your phone, allowing them to access only the page you left open. Well, with App L ...more

The iTunes App Store makes it easy to buy an app or game on someone else's behalf, and it's a great way to send an iPhone user a thoughtful gift. The Google Play Store doesn't have such functionality, but there are still a few workarounds to accomplish the same goal: gifting a ...more
Your iPhone's new home screen widgets are awesome — until they're not. Photos, in particular, is a big disappointment. It gives you a taste of having your favorite photos appear alongside your apps but ruins it by changing the photo randomly every hour without your input. Whil ...more
Emoji have taken over the world, so there's a good chance you regularly use (or overuse) emoji on your iPhone's keyboard just like everyone else. But before emoji were popular, there were emoticons, short for "emotion icons" — and iOS has a secret emoticon keyboard just waitin ...more
MacBooks are built for creation and creativity. They're built to withstand our careers, our hobbies, and our everyday use. I use mine every day, and there's nothing I'd recommend more for computing needs. However, not all MacBooks are built the same. The newer MacBooks models ...more
The Google Play Store exists so you can download as many apps as your heart desires (and as your memory can hold). Sure, you may only use them once, but it's your choice—and isn't that what life is really about? With that said, the Samsung Galaxy Note 2 already comes with a to ...more
Apple is set to release its latest operating system for iPad, iPhone, and iPod touch this fall, and if you haven't noticed yet from our iOS 7 softModder guides, it's going to be pretty slick. Gone are the boring old icons that have remained basically unchanged since the very ...more

Full disclosure: I really like Apple's stock ringtones on the iPhone. After all, there are over 50 to choose from if you include the classic ones. With all that choice, why would you ever need more? Personally, I get bored easily, and I'd like my music to play when people call ...more
Third-party ROMs like CyanogenMod are the ultimate form of customization for softModders. Hard-working developers offer us alternate Android experiences to replace our often bloatware-riddled stock ROMs. Installing custom ROMs is performed with a special type of software call ...more
I don't know about you, but nothing is more annoying than when my phone hits 15% and I'm nowhere near a charger. Not just because I know my phone will die soon, but until I reach a charger, I have to deal with the annoying low battery notification and LED light. Well, with And ...more
While the Twitch app for iOS came out way back in 2011, livestreaming iPhone games was a rarity until Apple recently updated its ReplayKit in iOS 11. However, Twitch hasn't jumped on the bandwagon yet, but that doesn't mean you can't livestream your iPhone games to Twitch righ ...more
When the Chromecast first came out about a year ago, developers were quick to find a way to root the streaming device. Google was almost as fast, however, in updating the Chromecast's firmware to close the loophole that this method used. Recently, the developers at Team Eurek ...more
