Can Proctorio Detect Your Phone or a Second Device?

Can Proctorio Detect Phones or Second Devices?

Can Proctorio detect phones? The short answer is no - Proctorio cannot directly detect a separate phone or second screen. The software lives inside your Chrome browser as an extension, and its reach stops at the boundary of that browser on that one device. It has no mechanism to scan your local network, communicate with other gadgets in the room, or identify what other hardware you own.

That said, "cannot directly detect" is not the same as "cannot get you caught." There are indirect ways Proctorio's monitoring can surface phone use, and understanding the difference is genuinely important - whether you are a student trying to follow the rules or an instructor building a fair exam policy.

Key Takeaways

• Proctorio cannot directly detect a phone or second device; it has no access to other hardware or your broader network.
• Webcam-based behavioral analysis can flag behaviors consistent with phone use, such as repeated head-turns or downward glances.
• A second monitor connected to your exam computer may be detectable depending on how the institution configures screen-sharing settings.
• Proctorio generates a suspicion report that a human reviewer interprets - nothing is automatically punished without human review at most institutions.

What Proctorio Actually Does

Before we can answer whether Proctorio can catch a phone, we need to be clear about what it actually monitors. Proctorio is a Chrome extension that activates during an exam session. Depending on how your institution sets it up, it can:

• Record your webcam and flag faces, lighting changes, or multiple people in frame
• Record your screen or require full-screen mode
• Track browser behavior like tab switching, copy-paste actions, or navigating away from the exam window
• Monitor your microphone for background noise or voices
• Analyze gaze direction using facial landmark detection to estimate where you are looking

All of this data feeds into an automated suspicion score, which a human reviewer at your institution then examines. Proctorio does not make final academic-integrity decisions - people do.

So Why Do Students Think It Can Detect Phones?

The confusion is understandable. Proctorio's marketing and some institutional policies describe it as comprehensive monitoring, which sounds like it can see everything. Additionally, some proctoring platforms (not all) do have features that prompt students to scan their room with a phone camera before the exam - which means the phone is temporarily part of the session. Once the exam starts, though, that connection typically ends.

There is also a kernel of truth buried in the confusion: a second monitor connected directly to your exam computer is a different story from a phone sitting on your desk.

Can Proctorio Detect a Second Monitor?

This is where things get more specific. If your institution enables screen recording or screen sharing, Proctorio can detect how many displays are connected to your exam computer. Operating systems report display information to applications, and a screen-capture tool can surface that. Some exam configurations will warn the student or flag the session if more than one monitor is active.

A phone or tablet you are holding or propping nearby is a completely separate device with its own operating system. Proctorio has no channel into that device. It cannot ping it, read from it, or know it exists.

The Webcam Problem: Behavior, Not Devices

Here is where the real risk lives. Even though Proctorio cannot see your phone, it can see you. If your webcam is active and you repeatedly:

• Tilt your head down toward a device in your lap
• Glance sideways toward a second screen
• Look off-camera in a consistent pattern
• Show a change in lighting that suggests a screen nearby

...those behaviors get flagged. A human reviewer looking at a suspicion report will draw their own conclusions. They may not be able to prove you used a phone, but they can see that your attention appeared divided.

This is the indirect detection risk. It is real, and it is worth taking seriously - not because we are encouraging academic dishonesty, but because honest students with, say, a pet that keeps walking by or an anxiety habit of looking away also get flagged for the same reasons. Understanding the system helps everyone.

What Proctorio Cannot Do

Let us be equally clear about the genuine limits, because overclaiming surveillance is its own problem:

What About AI-Generated Answers on a Phone?

This is a newer concern that instructors are increasingly aware of. A student could theoretically use a phone to consult an AI chatbot during an exam. Proctorio itself cannot detect this. However, if the exam is written and the responses look AI-generated, instructors may run submissions through an AI detector test afterward.

AI writing has recognizable patterns - certain sentence structures, hedged phrasing, and a particular kind of smoothness that stands out compared to genuine student writing. Instructors and institutions are increasingly familiar with these signals. So even if Proctorio never flags the session, the written output itself may raise questions.

If you are a student who drafts practice essays with AI assistance and wants to make sure your own voice comes through in final work, a tool like our free AI humanizer can help you rework AI-assisted drafts into something that reflects your actual voice. That is a legitimate use case - preparation and practice, not cheating.

What Should Students Do?

If you are taking a Proctorio-monitored exam and want to stay clearly within the rules:

1. Read your institution's specific policy. Proctorio is configured differently by different schools. Your exam instructions will say what is and is not allowed.
2. Clear your desk of devices. If phones are not permitted, remove them from the room entirely - not just face-down nearby.
3. Disable extra monitors. Unplug any second screen before starting the exam to avoid flags.
4. Minimize movement. Stay in frame, keep your eyes on the screen, and avoid habits that a gaze-tracker might misread.
5. Ask questions beforehand. If something is unclear in the policy, email your instructor before exam day, not during it.

What Should Instructors Know?

Proctorio's automated flags are not evidence on their own. A suspicion score is a prompt to look closer, not a verdict. Students with ADHD, anxiety, physical disabilities, or poor webcam setups will generate flags for reasons unrelated to dishonesty. Policies that treat automated reports as conclusive are unfair and, increasingly, legally questionable.

The Short Version

Can Proctorio detect phones? No - it cannot directly detect a separate phone or any device beyond your exam computer. It runs only inside your Chrome browser and has no access to other hardware, your phone's data, or your local network device list. What it can do is monitor your webcam behavior, flag gaze patterns that suggest distraction, and (in some configurations) detect a second monitor connected to your exam machine. The practical risk from phone use is not technical detection - it is behavioral: a human reviewer watching your webcam footage and drawing conclusions from where your eyes and head are pointing. Know what the software actually does, follow your institution's specific rules, and you will have a clear picture of what you are actually dealing with.
