In our first part on software-defined radio and signals intelligence, we learned how to set up a radio listening station to find and decode hidden radio signals — just like the hackers who triggered the emergency siren system in Dallas, Texas, probably did. Now that we can hear in the radio spectrum, it's time to explore the possibilities of broadcasting in a radio-connected world.
On April 7, 2017, residents in Dallas, Texas, woke to the sound of emergency sirens blaring all over the city. No one could shut them off, and after repeated efforts to contain the situation, the city had to shut down the entire system. While the media reported a sophisticated computer hack was responsible, the truth was much less high-tech.
It's official — the newest version of Google's mobile operating system is called Android 8.0 Oreo, and it's in the process of rolling out to many different devices. Oreo has plenty of changes in store, ranging from revamped looks to under-the-hood improvements, so there's tons of cool new stuff to explore.

Android's open source nature means it gets modified quite a bit. First, the phone manufacturer will add their customizations, then your carrier will add even more on top of that. Between the two, someone almost always adds a startup sound so that you and everyone around you will hear their jingle every time your phone reboots.
Smartwatches are great for notifications. No need to dig your phone out of your pocket or purse when someone texts you — just glance at your wrist! It's great for driving, walking, and any other activities where you need to stay connected to your surroundings. Except it can still be a little distracting, depending on your settings.
With Samsung's One UI 3.0 update, the main on-screen volume slider has a little menu button on the top of it. Tapping this will expand the slider into a full-blown volume panel, complete with controls for all of the various types of sounds your Galaxy might make. Standard stuff, really, but there's more to it.
Apple just rolled out the of iOS 14.5 to developers and beta testers, and one of the headlining features is the ability to keep your iPhone unlocked when your Apple Watch is nearby. As these things tend to go, Android has actually had this same feature for years, though it isn't quite as polished.
These days, the only thing your eyes view more than your phone's home screen is the backside of your eyelids. So it goes without saying that whatever picture you have as your background gets old pretty fast.
Things tend to get noisy when you're in a big group chat, which is why the notification sound for that thread shouldn't be your standard, attention-grabbing ringtone. But you don't want to set the default notification sound to something too subtle, otherwise you'd miss messages that actually matter.
Nowadays, even the dumbest thieves know that the first thing you should do after you steal a phone is turn on airplane mode. Not only does this make it harder for police to track the phone through cell tower triangulation, but it also disables security features the person you stole it from may have implemented — for instance, Samsung's Find My Mobile service.
There are at least 24,000 different Android devices, and they all have varying hardware components. This is why many developers publish several unique variants of their apps, which, among other things, helps accommodate all of the different display sizes and resolutions on Android phones and tablets.
Android's status bar is ever-present. It sits at the top of almost every screen in every app, making it the most prominent part of your Pixel's theme. So it only makes sense that Google would give you a way to change the icons it uses.
Imagine tilting the top of your phone away from you — it becomes a bit of a trapezoid, right? The top will appear smaller since it's further away, and the bottom will appear larger since it's closer to you — in other words, the perspective is all off. The same can be said of the pictures you take with an awkwardly-positioned phone.
If you upgrade to an iPhone 12, 12 mini, 12 Pro, or 12 Pro Max, you can take advantage of super-fast 5G speeds, but which 5G network are you actually getting and is it better than the others? Depending on your carrier, you may see 5G, 5G+, 5G UW, or 5G E in the status bar next to the signal strength, and there's a pretty big difference between them.
As you test out the new Quick Settings media controls in Android 11 and form an opinion, you'll notice one of the changes they made to the player besides the new location. For example, when you swipe away the mini version of these controls, the music keeps playing and the player still appears in the expanded view.
This Black Friday, there are a lot of smartphone deals. Whether you're picking up a new phone or already have one, one of the first purchases you'll want to make is a protective case. And just like nearly every other item, there's plenty of money to be saved on some great phone covers.
Apple has packed a lot of new features into the iOS 13 update, and practically no core app has gone untouched. The Messages app, in particular, got plenty of love, including new ways to dress and use your Memojis.
When it comes to rooting and modding any Android device, ADB and Fastboot commands will quickly become your two new best friends once you realize the power they have. From unlocking your bootloader to flashing any file you could ever want — if you're serious about the modding and customization game, you'll want to become acquainted with these commands as soon as possible.
Android 9.0 Pie moved the status bar clock from the right corner to the left to accommodate phones with notches, but there's one major downside for Samsung users: since no Galaxy phones have a notch, all this did was take away space for the notification icons that would otherwise start from the left corner.
With YouTube TV and DirecTV Now starting at $40/month, and others like Sling TV offering an eye-catching $25/month plan, streaming cable services may sound like a great way to cut costs while cutting the cord. But when you look at all the factors, the price you pay may very well end up being just as high as your traditional cable bill — if not more.
In case you hadn't heard, Google is now a legit cell service provider. Google Fi has its pluses and minuses, but the biggest upside is in the pricing. Depending on how much data you typically use, there's a good chance you could save a lot of money without sacrificing coverage by switching to Fi.
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 an app to an Android user.
The main draw for Google's Pixel series is the software. It rocks a clean version of stock Android instead of a heavy OEM skin like TouchWiz, it gets frequent prompt OS updates, the camera software is downright amazing, and it has perhaps the most fluid UI of any phone. But an understated advantage of the software is how dead-simple it is to modify with root-level tweaks.
Battery drain is a major pain point for Android users, though that promises to change thanks to Android Pie's new Adaptive Battery feature. But Google hasn't said much about the inner workings of this feature, only publicly stating that it uses AI to boost battery life. So we dug in to find out what's really going on under the hood.
These days, it seems new phones get announced every other week. We've grown accustomed to glossing over the specs, looking at some press renders, then moving on to check out the next phone. If you had done this in September 2008, you might have overlooked what would become one of the most important phones of all time.
Year in and year out, OnePlus flagships top our list of the best phones for rooting. Why? Primarily because rooting does not void your warranty, and OnePlus goes out of their way to make the whole process as easy as possible.
When it comes to modding Android, there's no better tool than Team Win's TWRP custom recovery. You can use it to root your phone, flash mods like Magisk or Xposed, and even replace the entire operating system with a custom ROM like LineageOS — honestly, there's not much this utility can't do.
When it works, Android's Smart Lock feature is incredible. There's no need to enter your PIN when your phone "knows" it's in your hands — just unlock and go. But Smart Lock, particularly its Trusted Places feature, can be finicky sometimes.
The great thing about competition is it drives innovation. But when a company tries to one-up its competitor, it's not always with something brand new. Sometimes, one party will draw heavy inspiration from the other — but hey, it's still all good, because the consumers benefit either way.
There are currently 27 available Animoji to choose from in iOS 13, but you're not limited to Apple's animated emoji characters — you can make your own. They're called Memoji, an available feature since iOS 12, and they're highly customizable.
When it's all said and done, it doesn't really matter who did it first — the more important question is who did it best. Still, it's nice to know who's really responsible for groundbreaking innovations in the smartphone space.
App updates bring new functionality, but they can also break old features or introduce changes no one wants. Unfortunately, if you're holding onto an older app version because you don't want to accept the update, it becomes a lot harder to keep the rest of your apps updated.
As with most social media platforms, Instagram can be a double-edged sword. On one hand, it's a great way to share and express yourself — but on the other, it can be just as effective at compromising your privacy. Thankfully, there are a few things you can do to protect yourself.
Snapchat is in the midst of a massive redesign — one that not everyone loves. Still, it's clear that this is a decision fueled by money, and Snap Inc. believes this redesign will help attract more advertisers. Even so, Snapchat has a few more tricks up their sleeves to make a little extra dough. And while the average user couldn't care less about ads, they very easily could care about custom Filters and Lenses.
Root, TWRP, Xposed, Magisk, custom ROMs — before you can have any of these, the first thing you should do is unlock your bootloader. Thankfully, the Pixel 2 and Pixel 2 XL are some of the most modder-friendly phones out there, so you only need to send a single fastboot command to unlock the bootloader.
Update 10/23: The hits just keep on coming. We're now seeing reports of a "smearing" effect when scrolling through apps on the Pixel XL 2. We'll expand on that at the bottom of this article, but it's still worth reading the background information on issues with LG's new POLED displays.
The Pixel 2 debuted a really cool feature that identifies any songs playing nearby and automatically displays the track's name on your lock screen. It's honestly one of the most inventive smartphone features we've seen in a while, especially considering how Google did it — but strangely, it's not enabled by default.
The Pixel 2 is a solid upgrade when compared to the 2016 model, but we've reached a point where the latest generation of a smartphone is never leaps and bounds better than the last. It's hard to justify dropping nearly a grand on a phone when it doesn't improve your situation much — especially when a few software tweaks will give you most of the upgrade for free.
After learning that you'll need to spend at least $74 on a special charger and a USB Type-C Lightning cable to enable fast charging on the new iPhone X and iPhone 8 models, you may be wondering why you can't just use the standard Lightning cable. While we can't answer why Apple didn't include the USB-C cable in the box with their new phones, we can explain why you need USB-C to enable fast charging.
