Most "hacked phone" fears are actually caused by shady apps, phishing, or a stolen password — not movie-style hacking. Here’s how to tell if something is wrong and how to fix it.
Warning signs
- Battery drains fast and the phone runs hot when idle.
- Unknown apps you didn’t install, or a remote-access app (AnyDesk/TeamViewer) you don’t remember adding.
- Pop-ups, redirects, and data usage spikes.
- OTPs arriving for logins you didn’t start, or friends getting spam from you.
What to do — step by step
- Uninstall any remote-access or unknown apps immediately.
- Update the OS and all apps; run a reputable security scan.
- Change passwords for email and banking from a different, trusted device; enable two-factor authentication.
- Review app permissions; remove accessibility/admin rights from suspicious apps.
- If problems persist, back up your data and do a factory reset.
Prevent it next time
- Install apps only from official stores; never sideload from links.
- Never install an app because a caller told you to.
- Keep the OS updated and use a screen lock.
FAQ
Can someone hack my phone just by calling me?
Practically no. Real compromise almost always needs you to install something or enter credentials on a fake page.
Does a factory reset remove spyware?
In most cases yes. Reset, then change key passwords from a clean device and re-enable two-factor authentication.
An app is asking for accessibility permission — is that risky?
It can be. Accessibility and device-admin rights are powerful; grant them only to apps you fully trust.
