Welcome to my ultimate guide on preventing remote access to your smartphone.
With over years of experience in Android security, I’m here to share everything you need to know to keep your device safe from hackers in plain English.
Whether a stranger is spying on you or someone you know is snooping, remote access to phones is a growing problem.
The good news is there are steps you can take to stop intruders in their tracks.
Let’s get started securing your smartphone!
How Hackers Gain Remote Access to Phones
Before learning how to stop remote access, it helps to understand the common ways hackers initially gain entry to devices:
Malware Apps
One sneaky way hackers infect phones is through malware apps masquerading as legitimate software.
For example, they may create a fake Flash Player app that secretly logs keystrokes or spies via your camera.
Always vet apps before downloading.
Stick to official app stores like Google Play rather than third-party sources, which are more likely to host malware.
Be wary of apps that ask for unnecessary permissions.
Phishing Links
Watch out for phishing emails, texts, and web links that trick you into downloading malware or sharing login credentials.
Hover over links to inspect their true destination before clicking.
If a link seems suspicious, delete it.
Unsecured WiFi Networks
Connecting to public WiFi like in a coffee shop makes it easy for hackers nearby to access your network traffic and inject malware or steal data.
Always use a VPN when on public networks.
Physical Access
If someone can physically access your unlocked phone, they could install spyware apps or change device settings to allow remote access.
Password protect your phone and don’t leave it unattended.
Now that you know common vectors, let’s move on to signs your phone may already be compromised.
Telltale Signs Your Phone Could Be Hacked
If you suspect remote hacking, watch for these red flags:
- Unfamiliar apps – An unknown app could be malware. Check your app list and google any apps you don’t recognize.
- Pop-up ads – A sudden onslaught of pop-up ads could indicate malware.
- High data usage – If your data usage suddenly spikes without changing habits, it may mean someone is secretly stealing data from your phone.
- Overheating – Excessive overheating can signal crypto mining malware infection.
- Weird noises – Some spyware uses your mic to listen in and may create static or clicking sounds.
- Higher bills – Unusually high monthly bills can occur due to background processes from malware.
- Sluggish performance – Malware strains your phone’s resources, causing lag.
- Unauthorized account access – Check bank and social media accounts for any logins from unknown devices, which could indicate credentials were stolen via your phone.
- Camera light activating – Some spyware activates your camera. The light coming on can clue you in.
If you notice any of these issues, it’s time to start securing your device.
How to Stop Remote Access Through Apps
Apps provide one of the easiest ways for hackers to control your phone remotely.
Here are smart app habits to stop unauthorized access:
Only Use Trusted Apps
Stick to downloading apps from the official Google Play store or Apple App Store.
Avoid third-party app stores, as they are more likely to host malware.
Also, be cautious of apps from lesser known developers.
Vet apps before downloading by Googling “[app name] + malware” to check for any red flags.
Check App Permissions
Pay attention to permission requests during app installation.
Avoid apps that ask for unnecessary or suspicious permissions they shouldn’t need to function.
For example, a calculator app asking for camera permissions could indicate malware.
Install Antivirus Software
Antivirus apps like AVG and Avast scan your phone for malware.
They can detect and remove dangerous apps.
Just be sure to only download antivirus software from official app stores, not third parties.
Keep Apps Updated
Developers frequently update apps to fix security issues.
Enable auto-updates in your device settings to maintain the latest secure versions.
For apps lacking auto-update, manually update them regularly.
Remove Unused Apps
Get rid of any unused apps lurking on your phone.
The fewer apps, the smaller your risk profile.
To uninstall, hold down the app icon and tap “Uninstall.” For pre-installed apps, disable them instead.
This prevents background processes that could create vulnerabilities.
Next up, let’s talk about securing connections to stop remote access through your network.
Preventing Remote Access Via Network Connections
Your phone’s connections like WiFi and cellular data provide gateways for hackers to slip through and control your device remotely.
Following these tips will keep connections locked down.
Encrypt Network Traffic
Encrypting data makes it unreadable to hackers intercepting your network traffic.
On Android devices, enable the “Encrypt Device” option in security settings.
For iPhones, network encryption is automatically enabled once you set a passcode.
Use a VPN
A VPN (virtual private network) funnels all your traffic through an encrypted tunnel.
This hides your IP address and online activities from prying eyes.
Enable a trusted VPN service like NordVPN or ExpressVPN to prevent remote access.
Only Connect to Secure WiFi
Using public WiFi like in cafes makes it easy for nearby hackers to sneak onto your network.
Only connect to private, password-protected networks you trust.
Completely avoid public WiFi if possible.
Disable WiFi Auto-Connect
Prevent your phone from connecting to networks automatically.
Hackers can create WiFi hotspots with trusted names to fool your device into connecting.
Manually select and connect to verified networks instead.
Turn Off WiFi When Not in Use
To prevent idle snooping, toggle off WiFi in settings when not actively using it.
Also turn WiFi off when not at home so your device won’t connect to unsecured public networks.
Use Cellular Data Instead of WiFi For Sensitive Tasks
Only use WiFi for general browsing.
When banking, shopping, or accessing sensitive accounts, opt for cellular data instead.
This prevents hackers connected to the same WiFi network from intercepting your activity.
Disable USB Debugging
Turn off USB debugging in developer options to prevent someone from accessing your device via a USB connection, which bypasses security measures.
Only re-enable if you have a specific need for USB-based development.
Securing your network connections goes a long way toward blocking remote access.
Now let’s look at some extra measures for keeping your phone locked down.
Extra Security Measures Against Remote Access
Here are a few additional precautions to implement:
Install a Firewall App
A firewall monitors network traffic and blocks unauthorized access attempts.
Apps like NetGuard and NoRoot Firewall add an extra layer of protection beyond your phone’s built-in firewall.
Frequently Change Passwords
Regularly change the passwords for your phone, accounts, WiFi network, and any connected smart devices to limit how long hackers have access if they manage to steal credentials.
Utilize strong, unique passwords for each account.
Enable Remote Device Management
Android Device Manager and Find My iPhone allow you to remotely lock, locate, or wipe your phone if it’s ever lost or stolen – preventing access to your data.
Disable USB Access on the Lock Screen
Turn off the setting allowing USB data transfer while your device is locked.
This prevents access to data via USB without unlocking the phone first.
Check the Connected Device List
Occasionally review the list of trusted devices connected to your phone in settings.
Remove any unfamiliar or deactivated ones to prevent unauthorized remote access.
Perform Regular Security Audits
Routinely audit your phone’s apps, settings, passwords, and network connections to catch any vulnerabilities or suspicious activity.
Security audits help identify issues before they’re exploited.
What to Do If Your Phone Is Hacked
If you confirm remote access, take these steps immediately:
- Change all account passwords entered on the device so hackers won’t maintain access.
- Back up any important data, then perform a factory reset to wipe the phone and eliminate malware.
- Remove the compromised phone from linked cloud accounts like iCloud after backing up data.
- Contact your carrier to suspend service on the hacked SIM card and request a new one.
- Install antivirus software on the reset device and run a scan to check for lingering malware before restoring data.
- Enable two-factor authentication on all accounts for an extra layer of security moving forward.
- If you believe the hacker was someone you know, consider filing a police report.
Now that you’re an expert on securing devices from remote access, let’s wrap up with answers to common questions.
