Yes, someone can track your phone without you knowing, using methods like spyware/malware, phishing, SIM cloning, public Wi-Fi, or even legitimate location sharing you've unknowingly enabled; these methods range from cybercriminals stealing data to people you know monitoring your location through installed apps or permissions. It's crucial to be aware of warning signs like poor battery life, unusual data usage, or strange app behavior and to take steps like using strong security, antivirus software, and checking app permissions to prevent unauthorized tracking.
Here are some ways you can tell your phone is being tracked: Unusual location activity: You see unexpected location alerts, unknown devices linked to your account, or unfamiliar apps with location access. Checking your location history or app permissions can help confirm this.
To stop location tracking on an Android phone, disable Location Services in Settings under Privacy or Location. Review app permissions and revoke location access for unnecessary apps. Use Airplane Mode or turn off GPS when not needed. Regularly update your device to patch security vulnerabilities.
You can check for trackers that are separated from their owners and currently near you at any time.
Apple has not added notifications for when someone is checking another person's location in Find My, under one exception. If someone decides to use the “Find Nearby” feature powered by Precision Finding, that will notify the other person that they are trying to find them.
Three-finger gestures on iPhone primarily activate accessibility features like VoiceOver (for screen reading and navigation) and Zoom (magnification), allowing scrolling, zooming, and text manipulation (copy/paste/undo) with specific taps and drags, though some text actions work without VoiceOver enabled for quick editing. Common gestures include three-finger double-tap to toggle VoiceOver speech, triple-tap for the screen curtain, and pinching/spreading with three fingers for copy/paste actions, notes this YouTube video.
Can I run a test to see if my phone is hacked? Yes, running an antivirus scan using a mobile security app like Norton 360 Deluxe can help you identify malware infections that could be granting hackers access to your device or data.
Hackers (or any creep with physical access to your phone) can install spyware or tracking apps that run in the background, monitoring your calls, messages, location, and online activity. These apps are often disguised as harmless programs, making them difficult to detect.
Code to check if phone is tapped: *#21# Code to show unknown connections and tracking (for Android): *#*#4636#*#* or *#*#197328640#*#* Code to show unknown connections and if someone is tracing you (for iPhone): *3001#12345#* Code to find your phone if lost or stolen (for Android): *#*#1472365#*#*
What is the 3-digit number to see if your phone is tapped? If your phone is on a CDMA network like Verizon or US Cellular, dialing the code *72 will tell you whether any of your calls or data are being forwarded to another number. Dial *#002# to uncover this kind of phone tapping on GSM networks.
Things we can do
Turning off your phone can prevent your location from being tracked because the device no longer sends signals to WiFi or cell towers. However, your service provider or internet provider will be able to see your last location before the phone was turned off and your device's current location once it's turned back on.
Dialing *#21# on your phone uses a USSD code to check the status of your unconditional call forwarding, revealing if all your calls, data, or texts are being redirected to another number without your knowledge, which can happen if someone accesses your settings. It's not a definitive hack detector, but it quickly shows if a carrier-level setting is diverting your communications, potentially to intercept sensitive information like 2FA codes, and can be disabled with ##21#.

Unusual sounds or echoes during calls
If you're noticing weird clicking sounds or high-pitched hums on multiple calls across different locations and with different people, it could be a sign that someone is eavesdropping or tracking your calls.
Generally, a phone that is powered off can't be actively tracked as it stops communicating with cell towers and Wi-Fi networks. However, its last known location is often recorded by your carrier or services such as Google Maps.
Dial codes like *#21# or *#62# help check call forwarding settings, but they can't confirm if your phone is hacked. They're useful for spotting suspicious redirections, but use trusted antivirus apps for reliable threat detection.
Why do Android phones turn up in breach headlines so often? Android powers most of the world's phones and many run outdated software, so attackers get more mileage for their effort. iPhones see fewer hits overall but attract highly skilled spyware crews.
Start by deleting unknown apps, updating your software, and running a security scan. Change passwords to any affected accounts and turn on 2FA. If you believe your phone has been hacked, start by removing any suspicious apps, updating your phone, and getting access back to any hacked accounts.
*3001#12345#* on an iPhone activates the hidden Field Test Mode, a diagnostic tool for network engineers and power users to see detailed cellular data like signal strength (dBm), cell tower info, and network quality, accessible by dialing the code in the Phone app and pressing call, often after turning off Wi-Fi for accurate cellular readings.
You can double-tap or triple-tap the back of iPhone to perform actions such as taking a screenshot, turning on an accessibility feature, running a shortcut, and more. Go to Settings > Accessibility > Touch > Back Tap. Choose Double Tap or Triple Tap, then choose an action.
