Is My Phone Being Monitored? 10 Signs and How to Check
That uneasy feeling that someone knows too much about where you have been or who you have talked to is worth taking seriously. Sometimes there is an innocent explanation. Sometimes a phone really has been set up to share information without its owner knowing.
The good news is that you can check a lot yourself, without special tools. Modern iPhones and Android phones have built-in settings that show which apps have unusual powers, which devices are signed into your accounts and who you are sharing your location with.
This guide covers 10 common warning signs, how to check both kinds of phone, and what to do if you find something. If you think the person monitoring you may be someone who could hurt you, read the safety section before changing anything.
First, a reality check
Most "spy" worries turn out to be something simpler: a shared account, location sharing someone forgot about, or an old family setting. That is actually good news, because those are easy to fix.
True stalkerware exists, but it usually needs someone to have had your unlocked phone in their hands, or to know your Apple or Google password. Keep that in mind as you go through the signs below. No single sign proves anything on its own.
10 signs your phone may be monitored
- Battery drains much faster than usual. Monitoring apps run in the background and upload data. Check which apps use the most power.
- Mobile data use jumps. Spyware sends recordings, photos and logs somewhere. An unexplained spike in data use is worth a look.
- The phone feels warm when idle. Heat while it sits unused can mean something is working in the background.
- Apps you don't recognize. Some stalkerware hides behind names like "System Service" or "Sync Manager."
- An app has device admin or accessibility access it doesn't need. These powerful permissions let an app control the phone or read the screen.
- An unknown profile or device management on an iPhone. A configuration profile can route your traffic or control settings.
- Someone knows things they shouldn't. Details from private messages, places you went or searches you made.
- Security settings changed on their own. For example, Google Play Protect turned off or a screen lock removed.
- Unfamiliar devices signed into your Apple or Google account. This is one of the most common ways people are monitored, and it needs no app at all.
- The phone was out of your sight and unlocked. If someone had it for a while and knows your passcode, that is enough opportunity to install something.

How to check an iPhone
iPhones are harder to infect with spyware than Android phones, so monitoring usually happens through accounts and sharing settings instead. Start here.
Run Safety Check
Apple built Safety Check for exactly this worry. Go to Settings > Privacy & Security > Safety Check. You get two options:
- Manage Sharing & Access lets you review, one by one, which people and apps can see your location, photos, notes and more.
- Emergency Reset instantly stops sharing with everyone, resets privacy permissions and signs out other devices.
Safety Check also has a Quick Exit button that jumps to the Home Screen if you need to hide what you are doing.
Check your Apple Account devices
Go to Settings > [your name] and scroll down to the list of devices. Tap any you do not recognize and choose Remove from Account. Then change your Apple Account password.
Look for profiles and device management
Go to Settings > General > VPN & Device Management. If you see a profile you did not install, and it is not from your employer or school, tap it and remove it.
Check location sharing
Open the Find My app and tap People to see who can see your location. Also check Settings > Privacy & Security > Location Services > Share My Location.
How to check an Android phone
Menu names vary a little between brands, so use the search bar at the top of Settings if you cannot find an option.
Scan with Google Play Protect
Open the Play Store, tap your profile picture, then Play Protect. Make sure scanning is on and tap Scan. Play Protect can detect many known stalkerware apps.
Review device admin apps
On a Pixel go to Settings > Security & privacy > More security & privacy > Device admin apps. On a Samsung Galaxy go to Settings > Security and privacy > Other security settings > Device admin apps. Only apps like Find My Device or your work profile should normally be there.
Check accessibility and notification access
Go to Settings > Accessibility and look under downloaded or installed apps. Then search Settings for Notification access or Device & app notifications. Apps with these permissions can read what appears on your screen and in your notifications.
Look at battery and data use
Settings > Battery > Battery usage and Settings > Network & internet > Data usage (or Connections > Data usage on Samsung) show which apps are most active. Look for names you do not know.
Check unknown sources
Search Settings for Install unknown apps. Apps allowed here can install software from outside the Play Store. Turn off anything you do not need.
iPhone vs. Android: where to look
| What to check | iPhone | Android |
|---|---|---|
| Built-in safety review | Safety Check | Security & privacy menu, plus Google Security Checkup |
| Malware scan | Not needed for App Store apps | Google Play Protect |
| Powerful app permissions | VPN & Device Management | Device admin apps, Accessibility |
| Signed-in devices | Settings > [your name] | myaccount.google.com > Security > Your devices |
| Location sharing | Find My > People | Google Maps > Location sharing, Find Hub |
Don't forget your accounts
Much monitoring happens without touching the phone at all. If someone knows your Apple Account or Google Account password, they may see your photos, messages backups, location and browsing history from their own device.
Take these steps:
- Change your passwords for your Apple or Google account and your email, from a device you trust.
- Turn on two-factor authentication so a password alone is not enough.
- Sign out of unknown sessions in Google at myaccount.google.com > Security > Your devices.
- Check WhatsApp Linked Devices (Settings > Linked devices) and log out of any computer you do not recognize. The same applies to Messenger, Telegram and similar apps.
What to do if you find something
Before you delete anything, pause and think about safety. Removing an app or changing a password can alert the person who set it up.
If you feel safe to act:
- Take screenshots of the suspicious app, profile or setting. This can help if you later report it.
- Remove the app, profile or unknown device.
- Change your passcode and account passwords.
- Update your phone's software. Updates close security holes.
When to factory reset
If you still suspect monitoring, a factory reset removes installed apps and settings. Back up only your photos and contacts, not full app data. On iPhone go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. On Android go to Settings > System > Reset options > Erase all data (on Samsung, General management > Reset).
After the reset, set the phone up as new with a fresh passcode, and do not restore an old backup that could bring the problem back.
If you're worried about your safety
Monitoring is often part of a wider pattern of control in abusive relationships. If you think a partner or family member is tracking you, your safety comes first.
- Consider using a safer device, such as a library computer or a friend's phone, to research and get help.
- Think about whether suddenly cutting off access could make the situation more dangerous. An advocate can help you plan.
- In the US, contact the National Domestic Violence Hotline at 1-800-799-7233, text START to 88788, or chat at thehotline.org. They are available 24/7.
- The Safety Net Project at nnedv.org has detailed guides on tech safety.
- If you are in immediate danger, call 911.
It is also important to know that secretly installing monitoring software on another adult's phone is illegal in the US and many other countries. You did nothing wrong by being monitored.
FAQ
Can someone monitor my phone without touching it?
Installing spyware usually needs physical access. However, someone who knows your Apple or Google password can see a lot from their own device, so securing your accounts matters just as much.
Does a factory reset remove all spyware?
It removes apps and settings on the phone itself. It does not fix a compromised account, so change your passwords and turn on two-factor authentication too.
Will antivirus apps find stalkerware?
Google Play Protect and reputable security apps catch many known stalkerware apps, but not all. Checking permissions and accounts yourself is still important.
Can my employer see my personal messages?
On a work-managed phone, your employer may see certain data, depending on how it is set up. Ask your IT team what they can access, and keep personal chats on a personal device.
