Is your smartphone spying on you without you even knowing it?

Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) recently revealed a startling new privacy threat.

Our smartphones’ ambient light sensors might be turned into makeshift cameras.

From brightness adjustment to privacy invasion

Ambient light sensors are commonplace in smartphones, primarily used to adjust screen brightness according to environmental lighting. However, CSAIL researchers have demonstrated that these sensors could potentially be repurposed to capture images of a user’s surroundings.

By employing a computational imaging algorithm, they managed to recover environmental images from the perspective of the phone’s screen, utilizing only the light intensity data from these sensors.

A comprehensive privacy threat

The implications of this discovery are far-reaching. 

“Ambient light sensors are tiny devices deployed in almost all portable devices and screens that surround us in our daily lives,” notes Princeton University professor Felix Heide. The study underscores a privacy threat that spans a broad spectrum of devices, previously underestimated in its potential impact.

Gesture interception and interaction capture

Beyond static images, the study suggests that ambient light sensors could intercept user gestures, like swiping and sliding, capturing interactions with phones during activities such as video watching. This capability challenges the belief that ambient light sensors are harmless in terms of private data exposure.

The call for tighter permissions

Yang Liu, a Ph.D. candidate at MIT EECS and CSAIL, warns that ambient light sensors, in conjunction with display screens, can capture our actions without consent, posing significant privacy risks. The researchers urge operating system developers to tighten permissions for these sensors, reducing their precision and sampling rate.

Looking ahead: Designing for privacy

To mitigate these security concerns, the study proposes granting users control over ambient light sensor permissions akin to camera permissions. Additionally, future device designs might include ambient light sensors positioned away from the user, such as on the side of the device, to prevent unauthorized visual data capture.

While the study’s findings prompt a reevaluation of sensor permissions and design, it’s equally important to recognize the broader context of smartphone security vulnerabilities. Let’s delve into the realm of spyware, another pressing concern where even the most vigilant users can find themselves compromised.

Understanding spyware vulnerability on your smartphone

You might not realize it, but your phone could be more exposed to spyware than you think. Just a small slip-up while you’re browsing the web, and you could accidentally invite a cyber-spy into your life. If you’re an Android user, be extra cautious. Your phone is usually more at risk than iPhones.

The telltale sign of spyware on your phone

Is your phone acting strange? Here are the telltale signs of spyware on your device.

Unusual noises: Beeping, faint voices or static during calls might not just be network issues. They could signal an eavesdropping attempt.

Performance lags: If your phone suddenly slows down or the battery drains rapidly, spyware might be hogging your resources.

Sensors activate unexpectedly: Modern smartphones signal when cameras and mics are in use. If this happens sans your input, investigate promptly.

Mysterious apps and files: New, unrecognizable apps or files might indicate that your phone’s security has been breached.

Excessive pop-ups and spam: An uptick in ads, error messages or scam texts may be adware, a common companion to spyware.

Overheating issues: Like performance lags, overheating can suggest that spyware is overworking your phone’s internals.

Several steps you can take to protect yourself from spyware on your smartphone

1. Have good antivirus software: Yes, antivirus protection can help detect and disable spyware on your smartphone. The best way to protect yourself from clicking malicious links that install malware that may get access to your private information is to have antivirus protection installed on all your devices. This can also alert you of any phishing emails or ransomware scams. Get my picks for the best 2024 antivirus protection winners for your Windows, Mac, Android & iOS devices.

2. Remove unfamiliar apps and files: If you suspect your phone has been hacked, promptly remove any unfamiliar apps.

3. Restart your device: Rebooting your phone can sometimes stop spyware from running.

4. Update to the latest software: As mentioned before, updates can patch vulnerabilities.

5. Be cautious when browsing: Avoid clicking on suspicious links or downloading files from untrusted sources.

6. Update your phone regularly: Updates often include security patches that can help protect your device from spyware and other vulnerabilities.

7. Don’t jailbreak your phone: Jailbreaking removes security restrictions that can make your phone more susceptible to spyware.

8. Look for unusual activity: This includes unusual noises during calls, performance lags, unexpected sensor activation, mysterious apps or files, excessive pop-ups and overheating.

9. Delete unwanted or unused apps: Some apps use your device’s camera and microphone and collect your data even while it is not in use. Getting rid of unused apps frees up storage space on your phone and declutters your lock screen. It can also eliminate one more potential app that might be collecting information from you unknowingly.

On an iPhone:

  • Hard press the app icon of the app you want to delete
  • Select Remove App
  • You’ll be prompted to confirm your decision in the next window by tapping Delete App
  • Then again by tapping Delete 


On an Android:

  • Go to the Google Play Store app
  • At the top right, tap the Profile icon
  • Select Manage apps & devices, click Manage
  • Select name of the app you want to delete
  • Select Uninstall

Android settings may vary based on the manufacturer’s settings. 

While it may seem like an extra effort to review and change your apps’ permission settings, it’ll give you more peace of mind knowing which apps have access to specific device functions and data. Most devices now have a dedicated part of their settings to view which apps are using the different functions of your phone and what data it has access to.

10. Changing camera settings: It may seem simple to just give access to your camera to certain apps. This way, you can easily use the camera function whenever you pull up the app to use. There are, however, apps that do not need access to your camera to function. Does your navigation app need access to your camera even when it is not in use? Take back control of your camera by using the steps below to find out which apps have access to your camera and turn it on or off.

On an iPhone:

  • Go to Settings
  • Scroll down and select Privacy or Privacy & Security
  • Select Camera
  • You can see which apps have access to your camera. Of course, you can leave the apps where it makes sense to have access to your camera toggle on. For apps that do not, you can toggle access off (it will be grayed out)

On an Android:

Android settings may vary based on the manufacturer’s settings.

  • Open Settings
  • Select Apps
  • Select the app you want to change (If you can’t find it, select ‘See all apps’)
  • Select Permissions to view if you allowed or denied any permissions for the app
  • To change a permission setting, select it, then choose Allow only while using the app, Ask everytime or Don’t allow

11. Restrict camera and microphone permissions: Restricting camera and microphone permissions can make it more difficult for spyware to access these features.

On an iPhone:

  • Go to Settings
  • Scroll down and select Privacy or Privacy & Security
  • Select Microphone
  • You can see which apps have access to your microphone. Of course, you can leave the apps where it makes sense to have access to your microphone toggle on. For apps that do not, you can toggle access off (it will be grayed out)

On an Android:

Android settings may vary based on the manufacturer’s settings. 

  • Open Settings
  • Select Apps
  • Select the app you want to change (If you can’t find it, select ‘See all apps’)
  • Select Permissions to view if you allowed or denied any permissions for the app
  • To change a permission setting, select it, then choose Allow only while using the app, Ask everytime or Don’t allow

The new iPad Pro looks like a winner

Hi, friends! Welcome to Installer No. 37, your guide to the best and Verge-iest stuff in the world. (If you’re new here, welcome, send me links, and also, you can read all the old editions at the Installer homepage.) 

This week, I’ve been writing about iPads and LinkedIn games, reading about auto shows and typewriters and treasure hunters, watching Everybody’s in LA and Sugar, looking for reasons to buy Yeti’s new French press even though I definitely don’t need more coffee gear, following almost all of Jerry Saltz’s favorite Instagram accounts, testing Capacities and Heptabase for all my note-taking needs and Plinky for all my link-saving, and playing a lot of Blind Drive.

I also have for you a thoroughly impressive new iPad, a clever new smart home hub, a Twitter documentary to watch this weekend, a sci-fi show to check out, a cheap streaming box, and much more. Let’s do it.

(As always, the best part of Installer is your ideas and tips. What are you reading / watching / cooking / playing / building right now? What should everyone else be into as well? Email me at installer@theverge.com or find me on Signal at @davidpierce.11. And if you know someone else who might enjoy Installer, and tell them to subscribe here.)

The Drop

  • The new iPad Pro. The new Pro is easily the most impressive piece of hardware I’ve seen in a while. It’s so thin and light, and that OLED screen… gorgeous. It’s bonkers expensive, and the iPad’s big problem continues to be its software, but this is how you build a tablet, folks.
  • Animal Well. Our friends over at Polygon called this “one of the most inventive games of the last decade,” which is obviously high praise! By all accounts, it’s unusual, surprising, occasionally frustrating, very smart, and incredibly engaging. Even the trailer looks like nothing I’ve seen before. (I got a lot of recommendations for this one this week — thanks to everyone who sent it in!)
  • Final Cut Camera. This only got a quick mention at Apple’s event this week, but it’s kind of a huge deal! It’s a first-party, pro-level camera app for iPhones and iPads that gives you lots of manual control and editing features. It’s exactly what a lot of creatives have been asking for. No word yet on exactly when it’ll be available, but I’m excited.
  • The Aqara Hub M3. The only way to manage your smart home is to make sure your devices can support as many assistants, protocols, and platforms as possible. This seems like a way to do it: it’s a Matter-ready device that can handle just about any smart-home gear you throw at it.
  • Battle of the Clipboard Managers.” I don’t think I’ve ever linked to a Reddit thread here, but check this one out: it’s a long discussion about why a clipboard manager is a useful tool, plus a bunch of good options to choose from. (I agree with all the folks who love Raycast, but there are a lot of choices and ideas here.)
  • Proton Pass. My ongoing No. 1 piece of technology advice is that everyone needs a password manager. I’m a longtime 1Password fan, but Proton’s app is starting to look tempting — this week, it got a new monitoring tool for security threats, in addition to all the smart email hiding and sharing features it already has.
  • The Onn 4K Pro. Basically all streaming boxes are ad-riddled, slow, and bad. This Google TV box from Walmart is at least also cheap, comes with voice control and support for all the specs you’d want, and works as a smart speaker. I love a customizable button, too.
  • Dark Matter. I’ve mostly loved all the Blake Crouch sci-fi books I’ve read, so I have high hopes for this Apple TV Plus series about life in a parallel universe. Apple TV Plus, by the way? Really good at the whole sci-fi thing.
  • The Wordle archive. More than 1,000 days of Wordle, all ready to be played and replayed (because, let’s be honest, who remembers Wordle from three weeks ago?). I don’t have access to the archive yet, but you better believe I’ll be playing it all the way through as soon as it’s out.
  • Black Twitter: A People’s History. Based on a really fun Wired series, this is a three-part deep dive Hulu doc about the ways Black Twitter took over social media and a tour of the internet’s experience of some of the biggest events of the last decade.

Screen share

Kylie Robison, The Verge’s new senior AI reporter, tweeted a video of her old iPhone the other day that was like a perfect time capsule of a device. She had approximately 90,000 games, including a bunch that I’m 100 percent sure were scams, and that iPod logo in her dock made me feel a lot of things. Those were good days.

I messaged Kylie in Slack roughly eight minutes after she became a Verge employee, hoping I could convince her to share her current homescreen — and what she’d been up to during her funemployment time ahead of starting with us. 

Sadly, she says she tamed her homescreen chaos before starting, because something something professionalism, or whatever. And now she swears she can’t even find a screenshot of her old homescreen! SURE, KYLIE. Anyway, here’s Kylie’s newly functional homescreen, plus some info on the apps she uses and why.

The phone: iPhone 14 Pro Max.

The wallpaper: A black screen because I think it’s too noisy otherwise. (My lock screen is about 20 revolving photos, though.)

Advertisement

The apps: Apple Maps, Notes, Spotify, Messages, FaceTime, Safari, Phone.

I need calendar and weather apps right in front of me when I unlock my phone because I’m forgetful. I use Spotify for all things music and podcasts. 

Work is life so I have all those apps front and center, too (Signal, Google Drive, Okta). 

Just before starting, I reorganized my phone screen because 1) I had time and 2) I knew I’d have to show it off for David. All the apps are sorted into folders now, but before, they were completely free-range because I use the search bar to find apps; I rarely scroll around. So just imagine about 25 random apps filling up all the pages: Pegasus for some international flight I booked, a random stuffed bell pepper recipe, what have you.

I also asked Kylie to share a few things she’s into right now. Here’s what she shared:

  • Stardew Valley took over my life during my work break.
  • I actually started 3 Body Problem because of an old Installer. Also, I loved Fallout and need more episodes. 
  • My serious guilty pleasure is Love Island UK, and I’ve been watching the latest season during my break.

Here’s what the Installer community is into this week. I want to know what you’re into right now as well! Email installer@theverge.com or hit me up on Signal — I’m @davidpierce.11 — with your recommendations for anything and everything, and we’ll feature some of our favorites here every week. And if you want even more recommendations, check out the replies to this post on Threads.

“I have always found Spotify’s recommendation algorithm and music channels to be terrible; wayyy too much fussing and tailoring required when all I want is to hit play and get a good diversity of music I will like. So I finally gave up and tried Pandora again. Its recommendation / station algorithm is so wildly better than Spotify’s (at least for me), it’s shocking how it has seemed to fade into cultural anonymity. Can’t speak for others, but if anyone out there is similarly frustrated with Spotify playlists, I highly recommend the Pandora option.” – Will

“Everything coming out of Netflix Is a Joke Fest has been 10/10.” – Mike

Mantella mod for Skyrim (and Fallout 4). Not so much a single mod, but a mod plus a collection of apps that gives (basically) every NPC their own lives and stories. It’s like suddenly being allowed to participate in the fun and games with Woody and Buzz, rather than them having to say the words when you pull the string.” – Jonathan

“The Snipd podcast app (whose primary selling point is AI transcription of podcasts and the ability to easily capture, manage, and export text snippets from podcasts) has a new feature that shows you a name, bio, and picture for podcast guests, and allows you to find more podcasts with the same guest or even follow specific guests. Pretty cool!” – Andy

“I have recently bought a new Kindle, and I’m trying to figure out how to get news on it! My current plan is to use Omnivore as my bookmarks app, which will sync with this awesome community tool that converts those bookmarks into a Kindle-friendly website.” – David

Turtles All the Way Down! Great depiction of OCD.” – Saad

“With all the conversation around Delta on iOS, I have recently procured and am currently enamored with my Miyoo Mini Plus. It’s customizable and perfectly sized, and in my advanced years with no love for Fortnite, PUBG, or any of the myriad of online connected games, it’s lovely to go back and play some of these ‘legally obtained’ games that I played in my childhood.” – Benjamin

Rusty’s Retirement is a great, mostly idle farm sim that sits at the bottom or the side of your monitor for both Mac and Windows. Rusty just goes and completes little tasks of his own accord while you work or do other stuff. It rocks. Look at him go!” – Brendon

“Last week, Nicholas talked about YACReader and was asking for another great comic e-reader app for DRM-free files. After much searching myself, I settled on Panels for iPad. Great Apple-native UI, thoughtful features, and decent performance. The free version can handle a local library, but to unlock its full potential, the Pro version (sub or lifetime) supports iCloud, so you can keep all your comics in iCloud Drive, manage the files via a Mac, and only download what you’re currently reading — great for lower-end iPads with less storage.” – Diogo

I have spent so much time over the years trying to both figure out and explain to people the basics of a camera. There are a billion metaphors for ISO, shutter speed, and aperture, and all of them fall short. That’s probably why a lot of the photographer types I know have been passing around this very fun depth of field simulator over the last few days, which lets you play with aperture, focal length, sensor size, and more in order to understand how different settings change the way you take photos. It’s a really clever, simple way to see how it all works — and to understand what becomes possible when you really start to control your camera. I’ll be sharing this link a lot, I suspect, and I’m learning a lot from it, too.

OpenAI could debut a multimodal AI digital assistant soon

OpenAI could debut a multimodal AI digital assistant soon

OpenAI has been showing some of its customers a new multimodal AI model that can both talk to you and recognize objects, according to a new report from The Information. Citing unnamed sources who’ve seen it, the outlet says this could be part of what the company plans to show on Monday.

The new model reportedly offers faster, more accurate interpretation of images and audio than what its existing separate transcription and text-to-speech models can do. It would apparently be able to help customer service agents “better understand the intonation of callers’ voices or whether they’re being sarcastic,” and “theoretically,” the model can help students with math or translate real-world signs, writes The Information.

The outlet’s sources say the model can outdo GPT-4 Turbo at “answering some types of questions,” but is still susceptible to confidently getting things wrong.

It’s possible OpenAI is also readying a new built-in ChatGPT ability to make phone calls, according to Developer Ananay Arora, who posted the above screenshot of call-related code. Arora also spotted evidence that OpenAI had provisioned servers intended for real-time audio and video communication.

None of this would be GPT-5, if it’s being unveiled next week. CEO Sam Altman has explicitly denied that its upcoming announcement has anything to do with the model that’s supposed to be “materially better” than GPT-4. The Information writes GPT-5 may be publicly released by the end of the year.
