Any device that connects to the internet can be hacked — and this includes your smartphone. It’s easy to treat your phone like an unbreakable personal safe; especially when, right now, chances are it contains personal information, your banking details, and data pertaining to your work. Your smartphone is an essential part of your life and that’s exactly what makes it a prime target for hackers.
Cybercriminals can exploit vulnerabilities in your phone to gain unauthorized access to your camera or microphone, potentially spying on you without your knowledge. Understanding the warning signs of a compromised device and taking proactive security measures can help you protect your privacy. In this guide, we’ll cover how to tell if your phone microphone is hacked, how to protect your phone camera from hackers, and other security tips for keeping your devices safe.
How Hackers Gain Access to Your Phone Camera & Microphone
Hackers have a variety of methods through which they can access your smartphone’s camera and microphone. Here are a few examples.
- Malware and spyware. Malicious software can be installed on your phone through phishing emails, fake apps, or malicious website downloads. Once installed, these programs can secretly access your camera and microphone.
- Unsecured apps. Some apps request excessive permissions, including camera and microphone access, even when they don’t actually need them. Malicious or poorly secured apps can then be exploited by hackers.
- Phishing scams. Hackers often send fake messages or emails that trick you into clicking a malicious link, which can then install spyware on your device.
- Network attacks. Connecting to unsecured public Wi-Fi can expose your phone to man-in-the-middle attacks, where hackers intercept your data and potentially gain remote control over your device.
- Physical access. If someone gets their hands on your phone, they can install tracking apps or spyware, allowing them to remotely activate your microphone and camera.
How to Tell If Your Phone Microphone Is Hacked
There are a few symptoms your phone might display if its microphone is being hacked. While these occurrences aren’t necessarily guaranteed proof of hacking, if you experience any of them (especially in combination) and aren’t able to determine any other cause, it might mean you’re being listened to.
Background noise or static during calls
If you frequently hear static, buzzing, or echoes during phone calls, it could indicate that someone is tapping into your microphone. While poor network connections can sometimes cause similar issues, consistent background noise on otherwise clear calls is worth investigating — not least because it’s annoying.
Unusual battery drain
A hacked microphone may continuously record and transmit audio data in the background, leading to excessive battery consumption. If your phone’s battery is draining faster than usual, even when not in use, spyware or malware could be the culprit.
Overheating when the phone is idle
Smartphones naturally heat up when in use, but if your device becomes warm when idle, it might be running hidden processes. A hacked microphone could be constantly recording and sending audio, causing the device to overwork and overheat.
Microphone indicator light turning on unexpectedly (iOS/Android)
Modern smartphones have built-in security indicators to let you know when the microphone is active. On iPhones, a small orange dot appears at the top of the screen when an app is using the microphone, and Android devices have a similar indicator. If you see this light turn on unexpectedly, it could mean an unauthorized app is accessing your microphone.
Higher-than-normal data usage, which may indicate spyware transmitting audio recordings
Spyware that records and transmits your conversations will consume significant amounts of data. If your monthly data usage suddenly spikes without an explanation, it’s worth investigating whether malware is secretly sending your recorded audio to a remote server.
How to Tell If Your Phone Camera Is Hacked
If your phone camera is compromised, it might allow hackers to capture photos or videos and potentially access other sensitive information. Here are some possible hacking signals to look for.
Camera indicator light turning on randomly
Just like with the microphone, modern smartphones display an indicator light when the camera is in use. If you notice your phone’s camera indicator turning on unexpectedly, an app or hacker may be accessing your camera without your permission.
Unknown photos or videos appearing in the gallery
If you find images or videos in your gallery that you don’t remember taking, your phone’s camera might be compromised. Hackers can remotely access your camera and capture footage without your knowledge.
The camera app is lagging, crashing, or running unusually slowly
If your camera app suddenly becomes sluggish, crashes frequently, or takes longer than usual to open, it could indicate that another application is using the camera in the background.
Apps suddenly request camera access without a clear reason
Be wary of apps that request camera access unexpectedly, especially if they have no need for it. Some malicious apps disguise themselves as legitimate software to gain access to your phone’s camera.
How to Protect Your Phone Camera and Microphone from Hackers
Here are some tips for how to protect your phone camera from hackers and prevent unwanted ears from listening in on your activities.
- Regularly review app permissions: check which apps have access to your camera and microphone. If an app doesn’t actively need these permissions, revoke them.
- Use strong passwords: secure your phone with a strong passcode or facial recognition to prevent unauthorized access.
- Install a trusted security app: use a reputable mobile security application to detect and remove spyware or malware.
- Avoid downloading unverified apps: only install apps from official stores like the Apple App Store or Google Play Store.
- Cover your camera when not in use: camera covers, or even simple stickers, can prevent hackers from spying on you.
Additional Tips to Keep Your Devices Secure
Enable two-factor authentication (2FA)
Two-factor authentication (2FA) adds an extra layer of security by requiring a second form of verification (such as a code sent to your phone) when logging into accounts. Combining 2FA with a strong password helps prevent unauthorized login attempts — and in the event that someone does manage to gain access to your password, you’re notified immediately.
Regularly update software and revoke unused app permissions
Hackers exploit outdated software to gain access to devices , so updates help to keep your software and apps secure. This also goes for laptop and computer operating systems: if you’re wondering how to protect your webcam from hackers, it’s important to keep all software updated. iolo Updater is an easy one-click way to ensure you’re keeping your software and drivers updated with the latest security patches. Combine this with regularly going through your app permissions to disable any that are no longer needed.
Be cautious of phishing attempts that install spyware
Cybercriminals often use phishing emails, messages, or fake websites to trick users into installing spyware. Be wary of unexpected messages that urge you to click on suspicious links or download attachments.
Use a VPN
A Virtual Private Network (VPN) encrypts your internet connection, making it harder for hackers to intercept your data, especially on public Wi-Fi. A high-quality VPN will improve the overall cybersecurity and privacy of all your devices.
Don’t let hackers pick up the phone
Your smartphone is a powerful tool, but without the right security measures, it can also be a gateway for hackers. By staying vigilant and following best practices, you can protect your camera, microphone, and personal data from cyber threats.

FAQ
What do I dial to see if my phone is hacked?
There is no universal code to check if your phone is hacked, but some codes can help you detect suspicious activity. For example:
- *Dial #21# to check if your calls or messages are being forwarded
- *Dial #62# to see where your calls are being redirected if you’re unreachable
While these codes may provide useful information, they are not foolproof. If you suspect hacking, use security apps or consult a professional.
Can my phone be hacked by visiting a website?
Yes, hackers can exploit vulnerabilities in websites to infect your phone with malware. This technique, known as drive-by downloads, installs malicious software on your device without your knowledge. Avoid visiting untrusted websites, and use a secure browser with anti-malware protection.
If my phone is hacked should I get a new phone?
Not necessarily. In most cases, you can remove malware by:
- Running a security scan using a reputable antivirus app
- Deleting any suspicious apps
- Resetting your phone to factory settings
Can your phone be hacked through WhatsApp?
While WhatsApp uses end-to-end encryption to protect messages, hackers can still exploit vulnerabilities through:
