Have you ever talked about something near your phone — like booking a holiday or buying new shoes — only to see an ad for it minutes later? You’re not imagining it. Modern smartphones are constantly listening for commands like “Hey Google” or “Hey Siri,” but those same microphones often collect background audio data for targeted advertising.
In this guide, we’ll explain why your phone is listening, how it happens, and exactly what you can do to stop it — especially if you live in Australia, where privacy protection laws are still catching up to Big Tech surveillance.
In the race for faster, lighter, and longer-lasting smartphones, graphene phones are often called the holy grail of next-gen mobile technology. Promising incredible durability, near-instant charging, and eco-friendly materials, graphene might just be the element that transforms how our devices are built and powered.
But are graphene phones really the future—or just another buzzword? Let’s break it down.
Smartphones are designed to be “smart” — but that often means being invasive. Voice assistants like Google Assistant, Apple’s Siri, and Amazon Alexa constantly monitor your microphone for wake words. Unfortunately, these systems sometimes record and store unintended conversations that can later be analyzed for ad targeting or algorithmic learning.
While tech companies claim this data helps improve “user experience,” the reality is that much of it contributes to profiling and marketing. In short — your phone isn’t just listening for convenience; it’s listening for data.
Here’s how you can take back control of your privacy on both Android and iPhone devices.
Go through your app permissions and revoke microphone access for apps that don’t need it.
Android: Settings → Privacy → Permission Manager → Microphone
iPhone: Settings → Privacy → Microphone
Look for suspicious apps — social media, shopping, or weather apps — that shouldn’t have mic access and turn it off.
💡 Pro Tip: Recheck permissions regularly. Some updates can re-enable them without notice.
Voice assistants are among the biggest culprits of passive listening. Turning them off drastically reduces background microphone usage.
Android: Settings → Google → Search → Voice → “Hey Google” → Turn Off
iPhone: Settings → Siri & Search → Turn Off “Listen for ‘Hey Siri’”
This simple setting alone can stop most always-on recording triggers.
Apps like Facebook, Instagram, and TikTok often access your mic when the app is open (and sometimes even when minimized).
Go to Settings → Battery or App Management, and restrict background activity.
On iPhones, use Screen Time to block apps from running when not in use.
By cutting background access, you reduce unnecessary audio and data collection.
Even with permissions off, Google’s core Android system still collects telemetry data, including microphone events. A de-Googled phone — like those available from FreedomTech — runs open-source, privacy-hardened operating systems such as:
GrapheneOS (Google Pixel)
/e/OS (Samsung & Fairphone)
CalyxOS (Pixel & OnePlus)
These systems remove Google trackers, block background listeners, and give users full control over what apps access the microphone. For Australians who care about privacy, it’s the ultimate fix.
Even when powered off, some phones can still retain active circuits capable of signal or sensor listening. To completely block all signals, including microphone activation, use a Faraday bag.
A Faraday bag is a signal-blocking pouch that prevents any wireless communication — including Bluetooth, Wi-Fi, 4G/5G, and NFC. When you place your phone inside, it’s effectively invisible to external devices.

If you’ve ever used voice assistants, your recordings are probably stored on remote servers.
For Google: Visit myactivity.google.com → Delete voice and audio activity.
For Apple: Settings → Siri & Search → Siri History → Delete Siri & Dictation History.
Doing this ensures your past voice interactions aren’t retained for AI model training or ad targeting.

Avoid apps that track microphone or background data usage. Instead, use:
Signal or Session for messaging (Australia-based privacy messenger)
DuckDuckGo Browser or Brave Browser for web searches
ProtonMail for email
These apps are open-source and transparent — meaning you can actually see what data they collect (if any).
Surprisingly, many privacy breaches happen because of outdated security patches. Always keep your phone’s OS and apps updated to reduce vulnerabilities. Privacy-first operating systems like GrapheneOS issue frequent micro-updates to prevent any microphone or sensor exploits.
Technically, yes — but only with hardware isolation. While disabling permissions and assistants helps, there’s always a chance the operating system or hidden firmware processes can still listen. That’s why Faraday pouches and de-Googled phones are the only true solutions for full protection.
If your goal is to stop both digital and physical listening, combining software privacy settings with hardware shielding gives you total peace of mind.
Your phone isn’t the only thing listening — smart TVs, speakers, and even cars can record audio data. Disconnect or disable microphones on all smart home devices if you’re serious about privacy.
Your smartphone is the most powerful data collector you own — but that doesn’t mean you have to accept being listened to. By following these steps, switching to a de-Googled phone, and using Faraday protection gear, you can take back control of your conversations and personal data.
