Overheating even when idle
Apps you never installed
Pop-up ads on the screen
Strange background data usage
Messages you didn’t send
Microphone or camera turning on unexpectedly
Slow performance for no reason

If you notice 2 or more of these, your phone may be compromised.

1. Update Your Android System and Apps

One of the easiest ways hackers break into devices is through outdated software. Manufacturers release security patches to close vulnerabilities. If you ignore updates, you leave your phone exposed.

How to update:
Go to Settings → Software Update → Download and Install
Also update apps via Google Play Store → Manage Apps → Update All.

2. Uninstall Suspicious or Unknown Apps

Most beginner-level hacking happens through apps installed outside the Play Store.
If you see apps with strange names or icons, delete them.

Steps:

Open Settings → Apps
Look through all installed apps
Remove apps you don’t recognize or don’t use

Avoid “free cleaners”, “battery boosters”, or unknown “optimizer” apps — many contain spyware.

3. Disable Unknown App Installations

If your phone allows apps to be installed from unknown sources, hackers can easily sneak in malware.

Turn this off:
Settings → Security → Install Unknown Apps → Disable for all browsers and file managers.

4. Check for Device Admin Permissions

Some malicious apps hide in the Device Administrator section, making them hard to remove.

To remove:

Go to Settings → Security → Device Admin Apps
Turn off access for apps you don’t trust
Uninstall them immediately

5. Use Safe Mode to Remove Malware

If a hacking app refuses to uninstall, restart in Safe Mode. This disables third-party apps.

Steps:

Hold the Power button
Long-press Restart
Tap Safe Mode
Uninstall all suspicious apps
Restart normally

Safe Mode prevents hackers from running their software. How to secure an Android phone from hackers.

Hackers often aim to steal account login details.
Change passwords for your:

Google account
Facebook, WhatsApp, Instagram, TikTok
Banking apps
Email services

Use a strong format like:
Wisdom@2025!Secure

Never reuse passwords across multiple apps.

7. Turn On Google Play Protect

Google Play Protect scans your apps and blocks harmful ones in real time.

Enable it via:
Play Store → Profile Icon → Play Protect → Turn On

This adds an extra layer of security.

8. Install a Trusted Antivirus App

A reliable antivirus can detect malware, spyware, and hidden threats.

Recommended apps:

Bitdefender Mobile Security
Kaspersky Mobile Security
ESET Mobile Security

Avoid free “random” antivirus apps — some are malware disguised as security tools.

9. Disable Unnecessary Permissions

Apps that access your camera, microphone, or SMS can easily spy on you.

Review permissions:
Settings → Apps → Permissions

Remove permissions from apps that don’t need them.

10. Factory Reset (Last Resort)

If your phone still behaves suspiciously even after cleaning it, a factory reset is the strongest solution.

Warning: This deletes everything.
Backup your photos, contacts, and files first.

Reset via:
Settings → System → Reset Options → Erase All Data

This eliminates all malware completely.

How to Prevent Future Hacking

Avoid connecting to free public Wi-Fi
Never click links from unknown SMS or WhatsApp messages
Don’t download apps from unofficial websites
Use two-factor authentication
Lock your phone with PIN, fingerprint, or face unlock

Small habits make a big difference.

Conclusion

Blocking hackers from your Android phone is easier than most people think. By keeping your software updated, reviewing installed apps, managing permissions, and enabling Google Play Protect, you can significantly reduce the chances of being hacked. For deeper infections, Safe Mode or a factory reset will clean your device entirely.
