How to Tell if Your Android Phone Has Spyware
Spyware can often go undetected, but there are several common signs that may indicate your phone is compromised. The United States Computer Emergency Readiness Team (US-CERT) highlights that spyware can operate in the background without visible signs, making it difficult to detect.
Here are some key symptoms:
Battery Draining Faster Than Usual: Spyware consumes resources in the background, draining your battery even when you aren’t using your phone extensively. Norton reports that spyware can cause unexpected battery drain due to constant data transmission and background processes.
Device Slowing Down: Spyware often strains your phone’s system resources, leading to sluggish performance, including lagging apps and system freezes. The US-CERT warns that performance issues, such as unexplained slowness, can be a sign of malware.
Unexplained Data Usage: Spyware may transmit your data to a remote server. Kaspersky explains that a sudden increase in data usage without a clear cause could indicate malicious apps or spyware that’s using your phone’s internet connection.
Unfamiliar Apps: Check for any apps you don’t recognize or don’t remember installing. According to Google’s Android Security 2023 Report, many spyware apps disguise themselves as legitimate apps to avoid detection.
Overheating: A phone running unusually hot even when idle could be a sign of malicious processes running in the background. Norton notes that overheating can be a symptom of spyware or other malware activities.
Strange Pop-ups or Ads: Unexpected ads or redirects to suspicious websites are common signs of adware and spyware. The Federal Trade Commission (FTC) warns that unwanted pop-ups could be linked to malicious apps or spyware.
How to Remove Spyware from an Android Phone
Once you’ve identified potential spyware, here are the most effective methods to remove it:
Option 1: Use a Spyware Removal Tool

Option 2: Manually Remove Spyware
For those who prefer a more hands-on approach, here’s how to manually detect and remove spyware:
Reboot into Safe Mode: Safe Mode disables third-party apps, making it easier to identify and remove malicious software. Google’s Android Security resources suggest that Safe Mode is a powerful troubleshooting tool when trying to isolate malicious apps.
Remove Suspicious Apps: Go to Settings > Apps and uninstall apps you don’t recognize or don’t remember installing. Trend Micro recommends checking for apps that appear suspicious or are disguised as legitimate software.
Check Device Administrator Settings: Some spyware apps request administrator privileges to prevent uninstallation. Go to Settings > Security > Device Administrators and revoke any permissions for apps you don’t trust. This is especially important for apps that may have hidden malicious functionality.
Scan for Root Access: Rooting your phone can expose it to spyware. Use a root checker app to verify if your phone is rooted. The Android Security Team provides resources explaining the risks of rooted devices, which are more vulnerable to spyware.
Option 3: Update Your Android OS
Regular software updates are crucial to maintaining your phone’s security. Android Security Bulletins regularly release information about critical updates that patch vulnerabilities, which spyware can exploit.
Go to Settings > Software Update > Download and Install to ensure your phone has the latest security patches.
Keeping your operating system up to date is essential to prevent exploitation by new threats.
Option 4: Perform a Factory Reset
If all else fails, a factory reset is the most thorough solution. However, it will erase all your data, so make sure to back up important files, photos, and contacts.
Follow the on-screen instructions to complete the reset.
Important Note: Make sure you back up your data before performing a factory reset to avoid losing important information.
How to Prevent Future Spyware Infections
To minimize the risk of future spyware infections, follow these precautionary measures:
Install Trusted Apps Only: Always download apps from official sources like the Google Play Store. Google Play Protect scans apps for malware, including spyware, and removes dangerous apps from the store. McAfee also advises checking app permissions before downloading to ensure they are legitimate.
Keep Your Android OS Updated: Regular updates ensure that your device has the latest security patches, which protect against spyware and other threats. Android Security Bulletins are a great resource for staying up to date.
Use Strong Passwords and Two-Factor Authentication (2FA): Enable 2FA on accounts that support it. The National Cyber Security Centre (NCSC) provides practical tips for setting up and using 2FA to secure your accounts.
Avoid Public Wi-Fi for Sensitive Transactions: Public Wi-Fi networks are a significant security risk. CISA (Cybersecurity & Infrastructure Security Agency) warns that unsecured networks can be used to introduce malware, including spyware, onto your device. Always use a VPN if you need to use public Wi-Fi for sensitive transactions.
Sources of Spyware Infection
Spyware often enters your device through malicious apps or phishing attacks. According to McAfee, mobile malware, including spyware, is frequently delivered through phishing links, fake apps, or infected ads.
Common sources include:
Malicious Apps: Downloading apps from unofficial sources can expose your device to spyware. Always review app permissions and read user reviews. Google Play Protect helps detect and remove harmful apps.
Phishing Attacks: Phishing is a major vector for spyware infections. The Anti-Phishing Working Group (APWG) reports that phishing attacks targeting mobile devices have increased significantly, often leading to spyware installation.
Infected Websites and Ads: Malicious ads, also known as “malvertising,” can be used to distribute spyware. Trend Micro warns against visiting suspicious websites or clicking on ads from untrusted sources.
The Dangers of Spyware
Spyware is dangerous for several reasons:
Privacy Violations: Spyware can steal sensitive data like personal photos, contacts, and passwords. According to Palo Alto Networks, spyware can compromise your privacy by collecting your private data without your knowledge.
Identity Theft: Spyware can record usernames and passwords, leading to identity theft. The FBI’s Internet Crime Complaint Center (IC3) regularly receives reports of identity theft linked to spyware.
Financial Losses: Some types of spyware are designed to steal financial information, enabling unauthorized transactions. The Financial Conduct Authority (FCA) warns about the rise of banking trojans that target financial apps.
