Tinkernut presents the Bluetooth headset hack! This video shows one of the vulnerabilities of some bluetooth headsets. To prevent this vulnerability, it's best to invest a little more money into a more secure headset and making sure your headset is turned off when not in use. You can find all of the links and scripts used in this video, as well as find answers to questions you may have at the link below:

While viewing notifications, I have a nasty habit of accidentally hitting Clear and getting rid of them all before I actually have a chance to read them. There is an easy way to view the notification history on Android, but if you turn off or reboot your Samsung Galaxy S4, the history is wiped clean.

The pressure underwater is undeniably strong. If you were to fill a balloon with water and take it underwater, it would not burst but would stay the same size because liquids are not compressed. The pressure is the same, inside and outside of the balloon. If you were to fill that same balloon with air instead, the lower it dives into water, the more it shrinks, until it eventually can't take the pressure anymore and bursts.

Certain contacts on my iPhone have special ringtones so that I know exactly who's calling or texting without looking at my screen (like Adele's "Hello" for all my exes). But when my phone is silenced and tucked away in my pocket, these contact-specific ringtones can't really help me out. Luckily, there's something else that can—custom vibration patterns.

For some time now, iPhone owners have been able to use Siri to listen to and reply to text messages, but that functionality has been lacking on Android. That is, until Google silently rolled out a similar feature for Google Now (thanks to Android Police for the tip).

Google Maps, in conjunction with the Android operating system, is a powerful tool for navigation that is often underutilized. While it's no secret that it can get you to wherever you're going and back, some of you might not know that you can use Google Maps without even having to touch the screen. Not having to touch your display means you can concentrate on other things, you know, like driving or eating that jelly-filled donut.

According to the American Osteopathic Association, "1 in 5 teens has some form of hearing loss," and some experts believe it's because of an increase in headphones use. While I understand that music, movies, and video games help keep children preoccupied, there's no reason why they can't be entertained at a healthy hearing level.

When anyone brings up Tasker, the first topic that always gets discussed is how powerful the Android automation app can be. But all of that power can be overwhelming for some people, so even if you're a Tasker pro, it's hard to share your awesome creations with friends that don't quite understand what's going on.

Say what you want about Samsung's TouchWiz UI being cluttered or overbearing, but one thing you can never complain about is a lack of features. In fact, it's been almost 8 months since I first took my Galaxy S6 Edge out of its box, but I'm still discovering features to this day.

Windows 10 runs on laptops, desktops, tablets, and even phones—but even though the operating system should scale accordingly, fonts and icons aren't always perfectly sized for every screen. Luckily, though, there's a handy new menu for adjusting the size of your screen's contents, which you can use to make everything bigger or smaller to match your preferences.

Russians are well known for their knack at documenting exciting and horribly beautiful events on the go, from insane car accidents to attempted insurance fraud and even a superbolide meteor streaking across the sky.

This tutorial shows you how to create an intruder alarm that sends you text message alerts when motion is detected. This may sound complicated but I am pretty confident any beginner with electronics should be able to do this just fine. The range sensor senses motion and tells your Arduino board to send the text (SMS). So you can leave the intruder detector at home, connected to your network, and still receive the SMS alerts, no matter where you are, as long as you have cell phone service.

The new Moto X may not have a lot going for it when it comes to hardware, but there are some pretty cool software features that makes it a tempting device. One of these cool features is its Active Display notifications that appear on the lock screen.

Android smartphones have all sorts of connectivity chips built in, including Bluetooth, Wi-Fi, GPS, NFC, and mobile data. But what about AM or FM radio, two of the most common methods of wireless communication?

We spend over 30 percent of our lifetimes sleeping—yet it never seems like enough, does it? Distractions ranging from work issues to personal relationships keep our minds racing well after they should be shutting down for the night, and the onset of smartphones has only added to this problem with the instant information and easy entertainment that they offer.

While it took Apple a damn-long time to finally include widgets in iOS, I do admire their implementation. Accessible from within any screen by pulling down the Notification Center (or, more correctly, the "Today" view), the home screen remains clean and minimal, which some of you with Android devices might appreciate—despite any Apple hatred you may have.

OS X is built upon a UNIX foundation, which grants you access to the benefits that UNIX offers, including the standard toolkit (make, gcc, clang, git, perl, svn, size, strings, id, and a lot more) via the command line developer tools, which are an essential if you're a developer. Aside from developers, the command line tools can offer benefits to normal users as well, like the ability to purge RAM for better performance.

When there's a crappy stock app you want to hide, the easiest thing to do is just bury it in the back of a miscellaneous folder. But what if there's an app you want to hide on your home screen that you actually use? For instance, what if you don't want everybody in eyeshot to see what banks you use, or don't want anyone to know about your "dating" apps or porn shortcuts?

BlackBerry has yet to find a home amongst the iPhone and popular Android phones, with sales plummeting over the last couple years, but this might be a thing of the past thanks to their latest device, the BlackBerry Priv. It has decent numbers so far and was even sold out on Amazon shortly after its initial release.

An app can request a wakelock to prevent your Android device from entering sleep mode so that it can sync data in the background. This obviously drains your battery, because instead of running in low-power sleep mode, your processor is fully activated while it performs its tasks.

For those times when you can't get something done by clicking a few buttons with your mouse, the Windows command prompt has always been an indispensable tool. But as much as advanced users have relied on this useful utility, it hasn't seen a significant update since the Windows 95 days.

Every phone has its issues and quirks, and the Nexus 5 is no exception to this rule. One of the most common troubleshooting questions asked by its owners is "Why does my Nexus 5 keep shutting off or restarting?" where the device suddenly decides to reboot or power off randomly on its own.

The Fire TV Stick, as well as the Fire TV, may be limited by Amazon's fight on piracy, but after a quick sideloading of Kodi, the floodgates are back open with the freedom to stream just about any video or song you want.

Amazon thinks that by simply removing an app from their Appstore, that they will stop users from accessing it. But with Android OS powering their Fire TV Stick and Fire TV, there really isn't anything they can do to prevent us from sideloading an APK onto the streaming media devices.

Microsoft did a wonderful thing in 2015: for the first time, it was offering a free upgrade to Windows 10 for all current Windows 7 and 8.1 users. And, if you were lucky, the upgrade process was relatively simple and painless. There were, however, some questions after the everything was said and done.

If you ever need to make calls and/or send texts to the U.S. or Canada from abroad, or even just receive them from those locations, there's an easy way to do so without breaking the bank. In fact, it's free, and all you need is a smartphone, computer, and some free tools.

You need a good microphone on your computer in order to make audio recordings, voice chat, or use speech recognition. However, not every computer comes with a built-in mic, and not every built-in mic works great.

Although they're often times the primary source of income for websites, on-site advertisements can annoy even the most tolerable reader. That's why ad blockers have been some of the most popular downloads on Firefox and Chrome for some time now, demonstrating that when it comes down to it, most people just want nothing to do with ads shoved in their face.

If you left your iPhone sitting unlocked, or have friends and family that like to play pranks, you may be stuck with an overly orange screen out of the blue. Or worse, your screen is normal most of the time, but seems to randomly change its tint in certain parts of the day.

If you're experiencing issues with an app or custom ROM and would like to report your problem to the developer, there's no better way to do it than by capturing a logcat. Android keeps track of all the commands that have been executed by various apps and services, which means that when something goes wrong, the error is clearly shown in this so-called logcat.

It might be difficult to admit, but a lot of us are probably guilty of lurking on Instagram profiles, whether it be an ex you've been keeping tabs on or someone cute you literally just met.

With every version bump, Android gets a new Easter egg that can be accessed by tapping the "Android version" entry in Settings. For the most part, these have generally been little animations or live wallpapers that depict the Android code name, but starting with version 5.0 Lollipop, things got a bit more interesting.

Windows has always had an "Administrator" account that allowed you to install programs and manage system files with elevated privileges. The difference between this account and a regular user account with administrator access was that you never got bothered by annoying User Account Control popups when you were logged in as Administrator.

Amazon is slowly trying to gain as much influence in the tech world as it has in the consumer market, and with the Amazon Fire HD 7, they have their eyes set on taking on the "budget tablet" space.

Yes, screen savers are fun to look at for a few seconds, but those animations actually used to serve a purpose beyond simple entertainment.

Back when CRT and plasma monitors were still a thing, screensavers served a purpose beyond just aesthetics: the moving images and patterns prevented static images from being burned into the display.

Unlike the suave 007 that Daniel Craig portrayed, I am not a spy, nor am I that charming, but I do occasionally enjoy taking a stealthy video. Maybe I'm a jerk, but I often catch people doing ridiculous things and just think, "Aren't you embarrassed?"

Playlists are more than just a list of songs that you enjoy listening to while in traffic or hosting a party—they're stories that illustrate who you are or your frame of mind at a certain point in your life.

Android Beam is one of those features that makes you look at technology in awe, wondering how exactly something like that works.

With a slab-style touchscreen device, butt dialing is always going to be a problem. While you're moving about, your phone can unlock itself and give your most recent contact a ring, leading to an awkward one-sided conversation where the other person gets to eavesdrop on everything you're doing or saying at that moment.
