Spyware infections on Android phones are common because the platform's openness—allowing sideloading and alternative app stores—makes it a target for criminals seeking to steal banking details or passwords, but Engadget notes that such infections leave detectable traces and are generally straightforward to remove without technical expertise. Recognising the warning signs and knowing the removal steps can help users regain control of a compromised device and protect sensitive information.

Warning signs include sudden battery drain, overheating, unexplained data or storage usage, persistent ads, browser redirects, unfamiliar apps, or unexpected permission requests for the camera, microphone or location, though these can also stem from an ageing device. Most infections occur through phishing links, fake attachments or sideloaded apps rather than physical tampering. Removal steps include running a Google Play Protect scan, installing a trusted antivirus app such as Bitdefender Mobile Security or Malwarebytes, checking and revoking suspicious device administrator permissions, booting into Safe Mode to delete stubborn malicious apps, and, as a last resort, performing a factory reset.
