How to Tell If Your Phone Is Being Tracked: Signs and Removal

If you may be in danger from a current or former partner, please read this section first. Removing tracking software can alert the person monitoring you, and that alert can escalate abusive behavior. Before you change anything on your phone, contact the National Domestic Violence Hotline at 1-800-799-7233 (US, free, 24/7) or visit stopstalkerware.org for international resources. A trained advocate can help you build a safety plan, preserve evidence, and decide on the right sequence of steps. The technical instructions below assume you have already considered these safety resources.

The rest of this guide covers what tracking actually looks like on a modern phone, how to check iPhone and Android for monitoring software, and how to remove it once you are ready. The detection steps follow the Coalition Against Stalkerware’s response framework, the National Network to End Domestic Violence Safety Net Project guidance, Kaspersky’s annual stalkerware threat reports, and Apple/Google published platform-security documentation. You can also review how phone location tracking actually works to understand the underlying technology.

Signs your phone might be tracked: technical indicators

Stalkerware and aggressive monitoring apps leave fingerprints. None of these signs alone proves tracking, but a cluster of them is a real warning.

• Battery drains much faster than before. Continuous GPS polling, microphone capture, and background uploads use measurable power. A phone that used to last all day and now dies by 4 PM, with no new heavy apps installed, is suspicious.
• The phone runs hot when idle. A device sitting on the table at 40 C or warmer with the screen off suggests something is running in the background.
• Cellular data use jumps. Stalkerware uploads logs, screenshots, and location pings. Open Settings and look at data usage by app over the last 30 days. Unexplained gigabytes from “System Services” or unfamiliar apps deserve attention.
• The screen wakes or lights up at odd times with no notification visible afterward. Some monitoring tools wake the device to capture screen state.
• Performance degrades. Lag when opening apps, slower keyboard response, or unexpected reboots can indicate background processes competing for resources.
• Unexpected texts arrive containing strange characters or codes. Some older stalkerware tools use SMS to send commands, and you may see fragments slip through.
• You hear faint clicks or echo on calls that were not there before. This one is rare on modern networks but still reported.

A 2023 Kaspersky report on stalkerware tracked over 31,000 unique mobile users globally affected by detected stalkerware in a single year, and the real number is higher because most stalkerware is never reported. If two or three of the signs above match your experience, treat it seriously.

Signs your phone might be tracked: behavioral indicators

Technical signs can be ambiguous. Behavioral signs often tell you more.

• The other person knows things you only said in private text messages or emails.
• They show up at places you went without telling them.
• They reference conversations from apps they should not have access to.
• They make off-hand comments about people you have been texting or calling.
• They seem to know when you are about to come home, leave work, or arrive somewhere new.
• They push you to keep your phone unlocked, share your password, or use shared cloud accounts.

TL;DR

If a partner consistently knows things they should have no way of knowing, the source is almost always one of three things: stalkerware on your phone, access to your cloud account (iCloud or Google), or a hidden physical tracker like an unknown AirTag in your bag or car.

How to check for tracking apps on iPhone

Apple’s App Store sandboxing and review process make iOS hard to compromise compared with Android. True iPhone stalkerware almost always relies on one of three vectors: a configuration profile, a jailbroken device, or stolen iCloud credentials. Check each.

Step 1: Look for configuration profiles. Open Settings > General > VPN & Device Management. On most personal phones this screen is empty. If you see a profile you did not install, or one named after an MDM tool from a workplace where you no longer work, that profile can route your traffic and read encrypted data. Apple documents profile removal in their official support guide. Tap the profile and choose Remove Profile.

Step 2: Audit Location Services per app. Go to Settings > Privacy & Security > Location Services. Scroll the entire list. Look for apps you do not recognize, or innocuous-looking apps (a calculator, a flashlight) with “Always” location access. Set unfamiliar apps to “Never”. For a deeper walkthrough see how to turn off location on iPhone.

Step 3: Check Battery by App. Settings > Battery shows the last 24 hours and 10 days of usage. An unfamiliar process consuming 15 to 30 percent in the background is a flag.

Step 4: Review Find My sharing. Open the Find My app, tap the People tab, and see who you currently share your location with. Anyone in this list can see you live, and you can tap their entry and choose Stop Sharing My Location.

Step 5: Audit iCloud.com sign-ins. From a separate computer, sign in to appleid.apple.com and review Devices. Any device on this list can pull your iCloud data, including location through Find My. Remove unfamiliar devices and immediately change your Apple ID password.

Step 6: Check for jailbreak signs. Look for apps named Cydia, Sileo, Zebra, or Checkra1n on your home screen or in App Library. Their presence indicates the phone was jailbroken at some point, which dramatically opens the surface for stalkerware.

How to check for tracking apps on Android

Android stalkerware is more common than iOS stalkerware because the platform allows sideloading and powerful Accessibility permissions. The Coalition Against Stalkerware tracks dozens of active commercial brands targeting Android.

Step 1: Review every installed app. Settings > Apps > See all apps. Sort by size or by last opened. Tap anything unfamiliar and read the package name. Stalkerware often disguises itself with names like “System Service”, “Wi-Fi”, “Sync Services”, or a generic gear icon. Search the package name on your computer if it does not look right.

Step 2: Check Accessibility services. Settings > Accessibility. Stalkerware on Android almost always abuses Accessibility because it is the only legitimate way for an app to read screen content, log keystrokes, and capture messages from other apps. Any enabled service you did not turn on yourself should be disabled.

Step 3: Check Device Admin apps. Settings > Security > Device admin apps (path varies slightly per manufacturer; on Samsung it is Settings > Biometrics and security > Other security settings > Device admin apps). Stalkerware uses this to prevent itself from being uninstalled. Disable Device Admin on anything suspicious before you try to remove the app.

Step 4: Run Google Play Protect. Open the Play Store, tap your profile picture, and choose Play Protect, then Scan. Google’s Play Protect documentation explains that the service scans roughly 200 billion app installs per day for harmful behavior. Play Protect does not catch every commercial stalkerware brand, but it catches many.

Step 5: Check Battery and Data by app. Settings > Battery > Battery usage, and Settings > Network and internet > Mobile data usage. Background processes that run constantly without an obvious reason are worth investigating.

Step 6: Look at notifications history. Some Android versions log a 24-hour notification history at Settings > Notifications > Notification history. Stalkerware sometimes leaks notifications during installation or updates.

How to remove stalkerware (iPhone)

Once you have decided removal is safe, work in this order. Each step closes a possible re-entry path.

1. Update iOS to the latest version. Settings > General > Software Update. Many older stalkerware exploits are patched in current iOS releases.
2. Remove unknown configuration profiles. Settings > General > VPN & Device Management.
3. Reset all settings. Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This clears VPN, profiles, and many privacy settings without erasing your data.
4. If concerns remain, do a full Erase All Content and Settings. Back up only data, not apps, to a clean computer first. Then set up the iPhone as new rather than restoring a backup that might contain the original infection.
5. Change your Apple ID password from a different device. Use a long unique password and turn on two-factor authentication.
6. Sign out of every device on appleid.apple.com that you do not currently control.
7. Review Find My sharing list and stop sharing with anyone you do not actively trust.

How to remove stalkerware (Android)

1. Boot into Safe Mode. On most Android phones, hold the power button, then long-press the Power Off option until “Reboot to safe mode” appears. Safe Mode disables third-party apps, which makes uninstalling stalkerware easier because it cannot block the action.
2. Disable Device Admin on suspicious apps first. If you skip this, the uninstall button will be greyed out.
3. Uninstall the suspicious apps. Settings > Apps > select app > Uninstall.
4. Run a full Play Protect scan and a reputable second scanner. See the next section.
5. If you are not sure you got everything, factory reset. Settings > System > Reset options > Erase all data. Set up the phone as new and reinstall apps one at a time from the Play Store.
6. Change your Google account password from a different device and review Security > Your devices to revoke unknown sessions. Turn on 2-Step Verification.

Anti-stalkerware tools that actually help

No app catches everything, but a focused scanner is much better than nothing.

If you are concerned about a physical tracker rather than software, Apple ships nearby AirTag alerts on iOS by default. On Android, install Tracker Detect from Google or AirGuard from F-Droid. Read more about unknown AirTag alerts and what they mean.

For abuse survivors: safety first before you remove

Removing stalkerware can be the safest move, or it can be the most dangerous, depending on the situation. The Coalition Against Stalkerware and the National Network to End Domestic Violence’s Safety Net project both warn that sudden loss of surveillance can trigger escalation. Before you act, work through this short checklist.

• Reach out for support first. Call the National Domestic Violence Hotline at 1-800-799-7233 (US) or chat at thehotline.org. In the EU, the Women Against Violence Europe network maintains national hotlines at wave-network.org.
• Use a different device or a trusted friend’s phone for the call. If your phone is compromised, the abuser can hear or read what you do on it.
• Document evidence before you delete anything. Take photos of the suspicious app names, settings screens, and any messages with your survivor advocate’s permission. This is the evidence that may support a protective order.
• Make a safety plan. Decide where you will be when the abuser realizes the monitoring is gone. Choose a safe location, a trusted contact, and a way to get there.
• Consider a separate phone. A clean prepaid phone, kept hidden, lets you keep emergency communication private even if the original phone stays compromised for now.
• Understand jurisdictional rules. In the US, federal law (18 USC 2511) makes intercepting electronic communications a crime, and most states layer additional stalking laws on top. The EU’s GDPR and the UK’s Computer Misuse Act 1990 offer parallel protections in Europe. A local domestic violence advocate can connect you to legal aid that knows your jurisdiction.

You do not have to figure this out alone, and you do not have to act today. The right sequence depends on your situation. The hotline and the Coalition Against Stalkerware exist to help you decide, in private, what comes next.
