Why Do I Feel My Phone Vibrate Even When No One's Calling or Texting?

A few months ago, I decided to give up on text message alerts. Not because I wasn’t interested in replying, but because I couldn’t handle having my phone vibrate at random. I had started experiencing “phantom vibrations,” the false sensation that your phone is vibrating. Unwilling to deal with constant pinging ringtones, and filled with disappointment and embarrassment every time I reached into my pocket to find that my brain had invented the sensation of a vibrating alert, I opted to merely mute everything.

It worked. I no longer feel that phantom phone itch in my leg or where the bottom of my purse brushes against my body. (As it turns out, very few texts are actually urgent.)

I’m not the only person who hallucinates that someone is trying to communicate with me. Psychologist David Laramie dubbed the feeling “ringxiety” in his 2007 dissertation on mobile phone use and behavior, but it wasn’t invented with the cell phone. In 1996, ”phantom-pager syndrome” made an appearance in a Dilbert strip. The phenomenon has since been studied across age ranges, professions, and cultures.

A 2012 study of 290 Indiana undergraduates found that 89 percent had experienced some degree of phantom phone vibration, averaging about once every two weeks. Nor is it limited to phone-obsessed college kids. A study of hospital staffers, who are frequently tethered to pagers and phones at work, found that 68 percent of the 176 workers surveyed experienced phantom vibrations.

It’s not just vibrations, either. Laramie’s 2007 study of 320 adults found evidence for aural hallucinations, too—two-thirds of the participants actually thought they heard their phone ringing.

But why people feel vibrations where there are none is still up for debate. In the 2010 hospital worker study, the Massachusetts-based researchers hypothesized that the phantom signals “may result from a misinterpretation of incoming sensory signals by the cerebral cortex.” They continue:

In order to deal with the overwhelming amount of sensory input, the brain applies filters or schema based on what it expects to find, a process known as hypothesis guided search. In the case of phantom vibrations, because the brain is anticipating a call, it misinterprets sensory input according to this preconceived hypothesis. The actual stimulus is unknown, but candidate sensations might include pressure from clothing, muscle contractions, or other sensory stimuli.

Recently, a University of Michigan phone study posited that ringxiety is linked to insecurity. The 2016 study found that people with attachment anxiety (who are insecure in personal relationships) were more likely to experience frequent phantom vibrations. This seems to make sense: If you’re insecure in your romantic relationship, you’re probably more likely to obsess about whether or not your partner is texting you. Expecting a message or call, or being particularly concerned about something that you might be contacted about, was further associated with phantom alerts.

However, most studies have found that only a tiny fraction of people are seriously bothered by the phantom signals—typically around 2 percent of the populations examined [PDF]. In the Indiana study, “few [participants] found them bothersome,” the researchers noted. The hospital workers studied didn’t, either. Many reported phantom-vibration sufferers didn’t try to do anything about it. Others successfully rid themselves of the sensation: Of the 115 hospital workers who experienced phantom vibrations, 43 attempted to stop it by taking their device off vibrate or carrying it in a different place, with 75 percent and 63 percent success rates, respectively.

The best way to rid yourself of phantom vibrations, it seems, is to be a super secure person with no social anxieties. Or, you could just try moving your phone to a different pocket. 

What's the Difference Between a Router and a Modem?

Despite using it every day, the internet is still a mystery to many of its users. If asked to explain how your home internet connection works, you may start with your router and modem. Both devices are essential to setting up a wireless network, but they serve distinct functions. Here are the major differences between the two pieces of hardware that make home internet run.

What is a Modem?

The modem is your home's gateway to the World Wide Web. It's often a skinny box with a row of LED icons on the front that tell you if it's on and connected to the internet. The name is short for modulator-demodulator—a phrase left over from the days of dial-up when modems worked by modulating telephone signals into frequencies that could send digital information.

Today, most modems use broadband connections like cable or satellite to transmit data. There are different types of modems built to fit different connections. If your internet service provider (ISP) uses cable or fiber internet, you'll need to plug a cable into the back of your modem, and if you still use a digital subscriber line (DSL), you'll have to plug in a phone line.

What is a Router?

You can connect to the internet with just a modem as long as you don't mind plugging your device directly into the Ethernet port. But if you want to provide internet to all the laptops, desktops, and smartphones in your home at the same time, you'll need a router.

Routers usually lie flat and have antennas sticking out of them. The router hooks up to your modem via an Ethernet cable and acts as a conduit between the direct internet and your home network. After connecting your devices, the router "routes" your modem's networking traffic their way, either through Ethernet wires or wirelessly through Wi-Fi (that's what the antennas are for). The router also works in the other direction by routing data sent from your computer back to the web.

Why Knowing the Difference Matters

When they've been sitting in the same spot in your home for years, it's easy to think of your router and modem as basically the same thing. But it's worth knowing the difference—especially if you care about improving your internet connection. Now that you know the router is what directs Wi-Fi signals, you can boost your home network by placing it in a central location away from electronic appliances. And as long as it doesn't interfere with the router, feel free to hide your modem behind a houseplant.

Hackers Used Facebook Quizzes to Steal Data from 60,000 Users

It’s been a tumultuous few months for Facebook. A data breach in fall 2018 exposed information about 30 million of its users to hackers. Only a few months later, the company was also criticized for paying individuals to voluntarily install an app that collected information about their smartphone habits. Now, it’s dealing with concerns that some of the quizzes available on the platform have been used to collect data from unsuspecting users.

According to CNN, the scheme is detailed in a lawsuit Facebook filed in California last week against developers Andrey Gorbachov and Gleb Sluchevsky. The defendants, who are based in Kiev, Ukraine, allegedly created quizzes like, “Do you have royal blood?” or “What does your eye color say about you?” as a way to access private user data. When Facebook users interacted with these tests, they were prompted to install browser extensions that allowed the alleged hackers to pose as those users, collecting information as well as taking control of their browsers. The improperly obtained information consisted of names, ages, and friend lists, which hackers then used for targeted advertising that they injected into users' feeds.

It’s possible the breach also resulted in the publication of 81,000 private messages in 2018, which was initially blamed on unspecified malware browser extensions that have not yet been publicly identified. Facebook has yet to confirm the two incidents are related, however.

Facebook said that the primary targets of the operation were Russian- and Ukrainian-speaking users, with 60,000 browsers compromised.

This isn't the only time Facebook quizzes have been tied to data breaches. Last year’s Cambridge Analytica controversy revealed that the firm used quizzes and questionnaires on Facebook to surreptitiously compile data on millions of users.

So what should you do about it? Online security experts caution against third-party apps that are accessed through Facebook. If you’re concerned about utilities that you installed without much thought, you can see a list by clicking on Settings, then the Apps link on the left menu. If you don’t recognize an app, it’s best to delete it.
