You can tell if your phone is hacked by watching for signs like sudden battery drain, high data usage, slow performance, unfamiliar apps, unexplained charges, pop-ups, or unusual background noises on calls, plus unexpected 2FA codes or activity on your accounts. To check, review your device settings for data/battery hogs, dial specific codes like *#21# for call forwarding, check linked devices in apps like WhatsApp, and run reputable antivirus software.
To check if your phone is hacked, look for signs like rapid battery drain, unexpected data spikes, new apps you didn't install, strange pop-ups, slow performance, or weird noises on calls, then use reputable antivirus software, check your account activity, and dial codes like *#21# to see if calls are being forwarded, taking steps like changing passwords and resetting to factory settings if needed.
Unfamiliar apps, losing access to your accounts, call and messaging features that suddenly stop working, and performance issues — such as apps crashing, a hot or loud device, and reduced battery life — are all common signs that your phone has been hacked.
Yes, if your phone is compromised, a hacker could gain access to everything — photos, texts, GPS location, microphone, camera, and even saved passwords. This typically requires powerful spyware, such as Pegasus, or a highly targeted phishing or other social engineering attack.
Start by deleting unknown apps, updating your software, and running a security scan. Change passwords to any affected accounts and turn on 2FA. If you believe your phone has been hacked, start by removing any suspicious apps, updating your phone, and getting access back to any hacked accounts.
If warning signs indicate that somebody hacked your phone, you should confirm if malware is present before beginning the recovery process. The simplest way to check if your phone is hacked is to run a reliable malware scan with a trusted anti-malware tool.
Does Turning Your Phone Off Stop Hackers? Mostly, yes. Everyday threats (spyware, phishing apps, scamware) can't survive a true shutdown. But against advanced spyware, a shutdown may not be perfect protection.
Why do Android phones turn up in breach headlines so often? Android powers most of the world's phones and many run outdated software, so attackers get more mileage for their effort. iPhones see fewer hits overall but attract highly skilled spyware crews.
Secure Your Accounts: Upon learning you've been hacked, immediately change passwords for all your online accounts. Start with those associated with sensitive information such as banking, email, and investments. From there, move on to accounts that contain less sensitive information such as social media and e-commerce.
Dial codes like *#21# or *#62# help check call forwarding settings, but they can't confirm if your phone is hacked. They're useful for spotting suspicious redirections, but use trusted antivirus apps for reliable threat detection.
For iOS, use Apple's Safety Check: To check if your iPhone has been hacked, go to Settings > Privacy & Security > Safety Check. This tool helps you review and revoke the access you've granted to people, apps, and devices, which is a common way iPhones are compromised.
Unwanted pop-ups/ads: Frequent strange pop-ups or ads can mean that malware is installed on your device. Suspicious device activities: Sudden clicks, apps opening or crashing on their own, background noises during calls, or being redirected to unexpected websites can indicate hacking.
Code to check if phone is tapped: *#21# Code to show unknown connections and tracking (for Android): *#*#4636#*#* or *#*#197328640#*#* Code to show unknown connections and if someone is tracing you (for iPhone): *3001#12345#* Code to find your phone if lost or stolen (for Android): *#*#1472365#*#*
Phone tapping sometimes involves call forwarding, where incoming calls are silently redirected to another number. Dialing MMI codes like *#62# or checking call settings can reveal whether calls are being diverted. If call forwarding is detected, you can disable it – instructions below.
You'll know your phone has a virus by symptoms like slow performance, rapid battery drain, high data usage, pop-up ads, strange apps, or unexpected messages to contacts, indicating malicious software is using your phone's resources or stealing data. To check, review your Settings > Apps for unfamiliar apps, monitor data/battery usage, and run a scan with a reputable mobile antivirus app like McAfee Security for Android from the Google Play Store or App Store.
On Android phones, select “verify apps,” which scans apps for malware. Depending on the type of phone you have, this is under Settings/Security or Google Settings/Security.
To clean a virus from your phone (especially Android), disconnect from the internet, reboot into Safe Mode to disable malicious apps, uninstall any suspicious apps, clear your browser cache, run a reputable antivirus scan (like Google Play Protect or a third-party app like Malwarebytes), and change important passwords; if issues persist, a factory reset is the last resort.
Turning off your phone effectively stops most hacking attempts since there's no internet connection and no malicious code can be executed.
What Else To Do if Your Phone Has Been Hacked
Experts and security professionals trust these phones:
Immediately change all your passwords on any accounts you think might have been affected. If you use the same password across several accounts, make sure they're unique from now on. Regularly changing your passwords is also a good habit to get into.
Set your phone to lock when you're not using it and create a PIN or passcode to unlock it. Use at least a 6-digit passcode. You also might be able to unlock your phone with your fingerprint, your retina, or your face.
