Smartphones have become our digital wallets, offices, banks, and personal diaries. We store photos, passwords, messages, money apps, emails, contacts, and sensitive information. Because of this, hackers constantly look for ways to break into people’s phones.
The good news?
You can protect your Android or iPhone very easily — even without being a tech expert.
In this updated 2025 guide, you’ll learn practical steps to secure your smartphone and keep hackers far away from your data.
Let’s begin.
1. Use a Strong Screen Lock
The first layer of protection is your phone’s lock screen.
Use one of these:
✔ PIN (6 digits or more)
✔ Password
✔ Fingerprint
✔ Face ID
Avoid simple PINs like:
❌ 1234
❌ 0000
❌ 1111
❌ Your birthday
Hackers try these first.
Tip:
Use a 6-digit PIN or alphanumeric password for stronger protection.
2. Turn On Two-Factor Authentication (2FA)
Two-Factor Authentication protects your accounts even if someone knows your password.
Apps that support 2FA include:
- Gmail
- TikTok
- Banking apps
With 2FA, a hacker cannot log in without your verification code.
Tip:
Always enable 2-step verification on Google and Apple ID — this protects your entire phone.
3. Keep Your Phone Updated
Software updates fix security holes that hackers can exploit.
Update includes:
✔ Security patches
✔ Bug fixes
✔ System stability
✔ New protection features
How to update:
Android: Settings → Software Update
iPhone: Settings → General → Software Update
Tip:
Turn on Auto-update to stay protected.
4. Avoid Downloading Apps Outside the Official App Store
One of the easiest ways hackers install malware on phones is through unofficial apps.
Avoid downloading from:
❌ Unknown websites
❌ Random APK files
❌ Untrusted links
❌ Fake app stores
Only use:
✔ Google Play Store (Android)
✔ Apple App Store (iPhone)
Tip:
If you must install APKs, scan them with antivirus first — but avoid this practice completely if possible.
5. Use a Trusted Antivirus (for Android)
iPhones don’t need antivirus, but Android phones benefit from security apps.
Best antiviruses:
- Avast
- Bitdefender
- Kaspersky
- Norton
- AVG
Antivirus helps detect:
✔ Spyware
✔ Malware
✔ Ransomware
✔ Keyloggers
✔ Unwanted apps
Tip:
Avoid fake antivirus apps that slow down your phone.
6. Don’t Use Free Public WiFi Without Protection
Free WiFi in cafés, hotels, airports, and malls is dangerous.
Hackers use it to intercept passwords and banking details.
If you must use public WiFi:
Avoid logging into banking apps
✔ Avoid online shopping
✔ Avoid entering passwords
✔ Use a VPN
Tip:
Prefer using your mobile data — it’s more secure.
7. Check App Permissions Regularly
Some apps ask for permissions they don’t need.
For example:
❌ A calculator asking for camera access
❌ A game asking for microphone access
❌ A wallpaper app asking for contacts
These are red flags.
How to check permissions:
Settings → Apps → Permissions
Tip:
Disable permissions for apps that don’t need them.
8. Avoid Clicking Suspicious Links
Hackers often send fake links through:
- SMS
These links may install malware or steal login details.
Signs of a suspicious link:
❌ Misspelled websites
❌ Unknown numbers
❌ Messages asking “Click this”
❌ Fake promotions
Tip:
Never click links from strangers — even from friends if they look suspicious, their account may be hacked.
9. Turn Off Bluetooth and WiFi When Not in Use
Hackers can access your phone through open Bluetooth or unsecured WiFi.
Tip:
Turn them off when you’re not using them to reduce the attack surface.
10. Use a Password Manager
Reusing the same password everywhere is risky.
A hacker who gets one password can get into all your accounts.
Use password managers like:
✔ LastPass
✔ 1Password
✔ Google Password Manager
✔ Apple Keychain
They help you create strong and unique passwords.
11. Lock Your Important Apps
Some apps contain sensitive information such as:
- Banking apps
- Gallery
- Notes
- Document apps
Use App Lock or built-in security features to protect them.
On Android:
Use App Lock (built-in on Tecno, Infinix, Xiaomi)
On iPhone:
Use Screen Time → App limits + passcode
12. Enable Find My Phone
This feature helps you:
✔ Find your phone if stolen
✔ Lock it remotely
✔ Erase your data
For Android:
Use Find My Device (Google)
For iPhone:
Use Find My iPhone
Tip:
Turn it on immediately after buying a phone.
13. Beware of Fake Charging Stations
Public charging ports can be hacked (“Juice Jacking”).
Hackers can install malware or steal files through USB charging.
Tip:
✔ Use your own charger
✔ Use a USB data blocker
✔ Avoid free charging stations
14. Avoid Rooting or Jailbreaking Your Phone
Rooting/jailbreaking removes phone protection layers.
This allows hackers to:
❌ Install hidden apps
❌ Access your files
❌ Control your phone remotely
Tip:
Never root or jailbreak if you are not a technical expert.
15. Back Up Your Data Regularly
If your phone gets hacked, you can still recover your:
✔ Photos
✔ Contacts
✔ Files
✔ Messages
Use:
- Google Drive (Android)
- iCloud (iPhone)
16. Use Alerts for Suspicious Activity
Both Android and iPhone warn you when apps behave strangely.
Watch out for:
- Apps draining too much battery
- Unknown apps installed
- Messages you didn’t send
- Rapid data usage
- Phone overheating suddenly
These are signs of hacking.
