Signs Your Phone is Being Monitored
Detecting stalkerware, spyware, and monitoring apps
Phone monitoring is different from account access. Someone can read your emails by logging into your Google account from their own device. But stalkerware—monitoring software installed directly on your phone—gives them access to everything: texts, calls, photos, location, even your microphone and camera.
This guide covers both the technical signs of monitoring software and the behavioral patterns that often accompany it.
The Two Types of Phone Monitoring
| Account-Based Monitoring | Device-Based Monitoring (Stalkerware) |
|---|---|
| They log into your iCloud, Google, etc. | Software installed directly on your phone |
| See synced data: emails, photos, location | See everything: texts, calls, apps, camera, mic |
| Detectable via account security checks | Often hidden from app list; harder to detect |
| Fix: Change password, enable 2FA | Fix: Factory reset (often the only sure way) |
This article focuses on device-based monitoring. For account access, see How to Check if Someone Accessed Your Google Account.
Physical Signs Your Phone May Be Compromised
Stalkerware runs in the background constantly, which causes noticeable effects:
🔋 Battery Drains Unusually Fast
Monitoring software sends data constantly. If your battery suddenly started dying much faster—and you haven't changed your usage—this is a common sign. Check Settings → Battery to see what's consuming power.
📶 High Data Usage
Stalkerware uploads texts, photos, call recordings to remote servers. Check Settings → Cellular/Mobile Data. Look for apps using significant data that you don't recognize or don't use often.
🌡️ Phone Runs Hot
Constant background processing generates heat. If your phone is warm when you haven't been using it, something may be running.
📱 Slow Performance
Monitoring software consumes CPU and memory. If your phone became sluggish around the time you suspect monitoring started, it could be related.
🔄 Unexpected Restarts
Some stalkerware causes stability issues. Random restarts—especially at consistent times—can indicate background software updates.
🔊 Strange Sounds During Calls
Clicking, static, or echo during phone calls can indicate call recording, though this is less common with modern stalkerware.
How to Check for Stalkerware
On iPhone
iPhones are harder to compromise because of Apple's security model. Stalkerware usually requires either:
- Jailbreaking — Look for Cydia, Sileo, or Zebra apps
- iCloud access — They use your Apple ID, not software on the phone
- MDM profiles — Enterprise management tools misused for spying
Check for MDM profiles: Settings → General → VPN & Device Management. If you see a profile you didn't install (especially if you don't work for a company that manages your phone), this is suspicious.
Check for jailbreak: Search your phone for "Cydia" or "Sileo" apps. Also try visiting cydia:// in Safari—if it tries to open an app, your phone may be jailbroken.
On Android
Android is more vulnerable because it allows app installation from outside the Play Store. Check:
- Unknown sources: Settings → Security → Install unknown apps. See which apps have permission to install other apps.
- Device admin apps: Settings → Security → Device admin apps. Stalkerware often requests admin privileges to prevent removal.
- App list: Settings → Apps → See all apps (including system apps). Look for vague names like "System Service," "Update Service," or anything you don't recognize.
- Play Protect: Open Play Store → Profile → Play Protect → Scan. Google's scanner can detect known stalkerware.
Known Stalkerware Names
Common stalkerware apps (may appear under different names):
- mSpy, FlexiSpy, Cocospy, Spyic
- Hoverwatch, eyeZy, uMobix, XNSPY
- TheTruthSpy, KidsGuard, Cerberus (legitimate but misused)
These apps often hide their icons or disguise themselves as system utilities.
Behavioral Signs (Often More Telling)
Technical detection is hard. Often, the person's behavior reveals monitoring:
- They know things they shouldn't. They reference conversations, plans, or information they weren't part of.
- They show up unexpectedly. They appear at locations they shouldn't know about.
- They react to private messages. They respond to texts or emails you sent to others.
- They had access to your phone. Even briefly—stalkerware can be installed in minutes.
- They gave you the phone. Pre-installed monitoring is common in abusive relationships.
- They're controlling about the phone. They get angry if you take it somewhere, change the passcode, or leave their sight with it.
What Stalkerware Can Actually See
Understanding capabilities helps you assess your risk:
| Data Type | Typically Accessible? |
|---|---|
| Text messages (SMS/iMessage) | ✅ Yes |
| WhatsApp, Signal, Telegram messages | ✅ Yes (usually) |
| Phone call logs and recordings | ✅ Yes |
| Photos and videos | ✅ Yes |
| GPS location (real-time) | ✅ Yes |
| Browsing history | ✅ Yes |
| Email (if app is on phone) | ✅ Yes |
| Social media activity | ✅ Yes |
| Microphone recording | ⚠️ Sometimes (premium features) |
| Camera access | ⚠️ Sometimes (premium features) |
| Keystrokes (passwords) | ⚠️ Some apps |
What To Do If You Find Stalkerware
If You're Safe to Remove It
- Document first. Screenshot the app, its permissions, and any evidence it exists.
- Factory reset. This is the only reliable way to ensure removal. Back up photos/contacts first (to a NEW account they don't have access to).
- Set up fresh. Use new passwords for everything. Enable 2FA. Don't restore from old backups (they may be compromised).
- Consider a new phone number. If they have access to your carrier account, they can still intercept calls/texts.
If You're Not Safe
Removing stalkerware can escalate abuse. Consider:
- Get a second phone. A cheap prepaid phone they don't know about for sensitive communications.
- Use public computers. For research and planning they can't see.
- Contact advocates. National Domestic Violence Hotline: 1-800-799-7233. They have tech safety experts.
- Make a safety plan before taking action that might alert your abuser.
The Account Monitoring Connection
Even if your phone is clean, they might monitor you through your accounts. Stalkerware is one vector; account access is another—and often easier.
Check your accounts for unauthorized access:
- Check Google/Gmail account access
- Check Facebook/Instagram account access
- Check iCloud: Settings → [Your Name] → Devices (on iPhone)
ForensAI analyzes your account data exports (Google, Apple, Facebook, Instagram, Microsoft, Dropbox, Snapchat, TikTok & X) to detect suspicious access patterns—logins from unknown devices, impossible travel, activity while you were asleep, and 20+ other risk patterns. It runs 100% on your device, so the analysis itself can't be monitored.
