How to spot and remove spyware on your Android phone
Security experts outline the warning signs of spyware on Android devices and how to safely remove it. Most infections can be resolved without technical expertise using built-in tools.
Android devices are more exposed to malware than iOS because they allow app sideloading and alternative app stores. This openness attracts bad actors who hide spyware inside disguised utility apps, fake updates or phishing messages.
Warning signs
Spyware typically runs quietly in the background but rarely without leaving traces. Sudden drops in performance, overheating or faster-than-usual battery drain can signal an infection. Unexplained spikes in mobile data usage or storage consumption, persistent ads, browser redirects and suspicious text messages are also red flags. Unfamiliar apps appearing on the device, or apps suddenly requesting access to the camera, microphone or location, can likewise point to spyware. None of these signs alone is definitive proof, since aging batteries and phones can misbehave for unrelated reasons, but several issues appearing together are worth investigating. Most infections happen remotely, through phishing links or apps sideloaded from outside the Google Play Store, which skip Google's vetting process.
Removing spyware
The first step is running a Google Play Protect scan from the Play Store app's profile menu. Installing a trusted antivirus app, such as Bitdefender Mobile Security or Malwarebytes, can catch threats a manual check might miss. Users should also check device administrator permissions in the security settings and revoke access for any suspicious app. If a malicious app can't be deleted normally, booting into Safe Mode temporarily disables third-party apps, making removal easier. A factory reset remains the last resort if spyware persists.
Staying protected
To prevent future infections, it's recommended to download apps only from the Google Play Store, checking developer profiles and permission requests before installing. Users should also disable installation from unknown sources in their security settings, regularly review installed apps for anything unfamiliar, install system updates promptly, and use strong passwords with two-factor authentication.
