In today’s digital age, smartphones hold a vast amount of personal information—photos, passwords, messages, banking details, and more. With this wealth of data, your phone is a prime target for hackers. If you suspect that your phone has been compromised, it’s important to act quickly. Here’s everything you need to know about the signs your phone has been hacked and how to fix the issue immediately.
Signs Your Phone Has Been Hacked
1. Unexplained Battery Drain
If your phone’s battery is draining faster than usual, it could indicate that malware is running in the background. Hackers may use your phone for malicious tasks, which consumes extra power.
How to Fix It:
Check your phone’s battery usage under Settings. Disable any suspicious apps or perform a full device scan using a trusted antivirus app.
2. Increased Data Usage
Sudden surges in data usage can be a sign that your phone is being accessed by unauthorized apps or hackers. This may happen if malicious software is transmitting data from your device without your knowledge.
How to Fix It:
Go to Settings > Data Usage and monitor apps using excessive data. If you spot anything unusual, remove or disable the app.
3. Suspicious Activity on Accounts
If you notice unauthorized purchases or changes to your social media accounts, emails, or bank accounts, it could mean that a hacker has gained access to your personal information.
How to Fix It:
Change your passwords immediately and enable two-factor authentication (2FA) on all your accounts to secure them further.
4. Pop-Up Ads and Unwanted Apps
Frequent pop-up ads and apps you didn’t install can be signs that your phone is infected with malware. Hackers often install apps remotely without your knowledge, which could lead to invasive ads and privacy breaches.
How to Fix It:
Uninstall suspicious apps and clear your phone's cache. You can also use an antivirus app to perform a full system scan.
5. Unusual Phone Behavior
If your phone is acting unusually—such as freezing, crashing, or restarting on its own—it could be a sign of a hacker’s presence. Malicious software can disrupt your phone’s normal operations.
How to Fix It:
Perform a factory reset after backing up your important data. This will remove any malicious software from your phone.

6. Unusual or Excessive Phone Activity
If your phone is making calls or sending texts without your input, it’s possible that a hacker has gained control of your device. This type of activity may also include unusual outgoing data.
How to Fix It:
Check your call logs and messages for unfamiliar activity. You should also perform a security scan and remove any suspicious apps or files.
7. Slow Performance
A hacked phone often experiences slower-than-normal performance because malicious apps and malware run in the background, consuming resources.
How to Fix It:
Close unused apps and run a full system scan using a reputable mobile antivirus app. A factory reset can help remove any lingering malware.
8. Overheating
If your phone is overheating for no reason, it could be due to unauthorized processes running in the background. Hackers may be using your phone’s resources for their own purposes, such as mining cryptocurrency.
How to Fix It:
Ensure that no apps are running in the background. Close all unnecessary apps and check for any strange processes in your phone’s task manager.
9. Unusual Charges on Your Phone Bill
If you notice unexplained charges on your phone bill, it may indicate that a hacker has been using your device for premium-rate services or fraudulent transactions.
How to Fix It:
Review your phone bill carefully and contact your mobile carrier for details. Consider switching to a more secure payment method for any online transactions.
10. Sudden Text Messages or Emails with Strange Links
If you receive odd text messages or emails containing links that seem out of place, there’s a chance they are phishing attempts designed to steal your personal information.
How to Fix It:
Do not click on any suspicious links. If you’ve already clicked on one, immediately scan your phone for malware and change your passwords.
How to Fix a Hacked Phone
11. Perform a Full Security Scan
Start by using a reputable antivirus app to scan your phone for any malicious software. Popular apps like Norton, McAfee, and Bitdefender offer comprehensive mobile security solutions.
12. Change Your Passwords Immediately
Once you’ve confirmed your phone has been hacked, change the passwords for your important accounts—such as email, banking, social media, and shopping sites. Use a password manager to generate strong, unique passwords.
13. Enable Two-Factor Authentication (2FA)
Activate 2FA on all your accounts that support it. This adds an extra layer of protection, even if your password is compromised.
14. Check for Unusual Permissions
Review app permissions to see if any apps are asking for access to sensitive information that they shouldn’t need, such as your contacts or microphone.
How to Fix It:
Revoke unnecessary permissions and uninstall any apps that seem suspicious.
15. Update Your Operating System
Hackers often exploit security vulnerabilities in outdated operating systems. Regular updates are crucial for protecting your phone from the latest threats.
How to Fix It:
Go to Settings > Software Update to ensure your phone is running the latest version of the operating system.
16. Reset Your Phone to Factory Settings
If the hack is severe, performing a factory reset will wipe all data from your phone and restore it to its original settings, removing any malware or malicious apps.
How to Fix It:
Before resetting, make sure to backup your important data, such as contacts and photos, to a cloud service.
17. Contact Your Mobile Carrier
If you’re experiencing financial issues, like unexplained charges or premium-rate service subscriptions, contact your mobile carrier to investigate the matter further.
18. Avoid Public Wi-Fi Networks
Public Wi-Fi networks are often unsecured, making it easier for hackers to intercept data. Avoid using them for sensitive activities such as banking or entering passwords.
19. Use a Virtual Private Network (VPN)
A VPN encrypts your internet connection, making it more difficult for hackers to monitor your online activities and steal your personal information.
How to Fix It:
Download a reputable VPN app and use it whenever you connect to the internet, especially on public networks.
20. Monitor Your Accounts Regularly
Even after fixing your phone, it’s important to stay vigilant. Regularly check your bank statements, social media accounts, and email for suspicious activity.
21. Avoid Clicking on Suspicious Links
Be cautious of phishing attempts via text messages, emails, or social media. Never click on links from unknown sources, and always double-check the URL.
22. Check Your Installed Apps
Some malicious apps may be hidden on your device. Go through your apps and uninstall anything unfamiliar or suspicious.
23. Install a Mobile Security App
After fixing your phone, make sure to install a reliable mobile security app that offers real-time protection. Apps like Norton Mobile Security and McAfee Mobile Security can prevent future threats.
24. Disable Bluetooth and NFC
Hackers can exploit Bluetooth and NFC (Near Field Communication) connections. If you’re not using them, disable these features in Settings.
25. Enable Device Encryption
Most smartphones offer built-in encryption options that make it harder for hackers to access your data. Make sure this feature is enabled in your phone’s security settings.
26. Check for Unusual Account Activity
Review your recent account activity, including social media, email, and banking accounts, to detect any unauthorized changes or transactions.
27. Use Anti-Theft Features
Many smartphones come with built-in anti-theft tools that allow you to remotely lock or wipe your phone if it gets lost or stolen. Make sure these features are enabled.
28. Avoid Jailbreaking or Rooting Your Phone
Jailbreaking (iPhone) or rooting (Android) your phone removes built-in security features, making it more vulnerable to hacking. Avoid this practice if you want to keep your device secure.
29. Educate Yourself About Phishing Scams
Phishing is one of the most common ways hackers gain access to phones. Educate yourself on how phishing scams work, and always be cautious when receiving unsolicited messages.
