If you have to ask that question, you may have some valid concerns about your personal data. You might keep your cell phone safe and locked with a PIN code, a fingerprint, facial recognition, etc. But is that enough? Sadly, there is a way someone can spy on your phone without ever touching it. It’s called spyware and has many ways to get inside your mobile device.

    How to know if someone is spying on your phone

    Here are the most common warning signs that your phone is being tracked, tapped, or monitored by spyware software:

    1. Anomalous data usage

    You probably know your monthly mobile data usage. If you notice any strange data usage spikes, it may be a sign of spy apps. If someone is spying on your cell phone, they’re using the network to download the data collected on you.

    2. Unusual activity on linked accounts (Google, Facebook, iCloud)

    As we mentioned, someone can start spying on you via your iCloud account – multiple spyware mobile apps do just that. However, unusual logins and other activity on platforms like Google and Facebook may also signal a breach in your defense. 

    3. Weird pop-ups

    We’re not talking about the GDPR or “Please disable AdBlock” stuff here. If you’re receiving push notifications for fake virus alerts and such, it may be a sign that your mobile phone is infected by adware – an obnoxious form of malware. From being annoying to carrying phishing attempts, they threaten your security.

    4. Phone getting slower

    If your cell phone is old or filled to the brim with apps, it’s natural. But if it’s not, you should be worried. Spy apps use their share of processing power to track your phone.

    5. Random reboots

    Your phone should not reboot without your say-so or an obvious critical error. Frequent unexpected reboots may be a sign that your phone has been hacked. 

    6. Longer or impeded shutdowns 

    This one is hard to notice because we hardly ever shut down our phones these days. However, if your phone is taking a long time to shut down – or just doesn’t shut down – it may be due to interference from the spy apps. Try it a few times to be sure. 

    7. Your emails end up blocked

    Have your friends or coworkers missed your emails because their firewalls blocked them? This may indicate that malware is operating on your phone and infecting your correspondence.

    8. The phone wakes up randomly 

    So you left your phone idle, it went into standby mode and possibly locked the screen. And suddenly, it lights up, yet there aren’t any incoming calls, messages, push notifications, or anything similar. This may be a sign that someone hacked your smartphone.  

    9. Interference outside phone calls

    You know how your phone causes interference with nearby electronics when you’re on a phone call? Well, it shouldn’t do it when you’re not. In these situations, it may be a sign of a listening app sending information to whoever is stalking you. 

    10. Weird noises during phone calls 

    Mobile phones have advanced to the point where you shouldn’t hear random sounds and distant voices during your phone conversations. If this keeps happening – and it’s not just background noise from the end of the line – someone may be tapping your call

    11. Weird texts

    Who’s texting these days? In any case, if you receive weird text messages that are weirder than the usual marketing stuff, those may be control messages meant for a spy app on your phone. Those messages usually contain strange symbols, character combos, and such. 

    12. Unusual battery drainage

    Has your battery started draining faster without any particular reason (like installing new apps)? Well, spy apps need the energy to function just like any other piece of software, and if they’re constantly recording your audio, they need quite a bit more. 

    On the off chance that it’s just the battery getting old, try using the battery with another device (if your smartphone doesn’t have a replaceable battery, take it to the service or something). 

    13. The battery heats up while idle

    Unless you have one of those phone models that just shipped with an exploding disaster battery, your phone should not be heating up when idle. While a single occurrence of that may be explained by some app going awry, if you experience this on the regular, something is amiss – and you probably have a spy app on your hands. 

    14. Autonomous app storage permissions (for Android phones)

    If you find your Android phone allows downloading and installing apps outside of the Google Play Store without asking you first, you might be dealing with mobile spyware.

    You can check this by going through your Storage permissions in the Settings. 

    Do you have unfamiliar apps on your phone that can store stuff? If so, someone may be spying on you.

    15. Bad screenshot quality 

    Word around the block is that keyloggers – spyware that records your inputs (read: typing) – can mess with screenshot quality. So if you notice your screenshots aren’t looking as good as they usually do, this could indicate your phone is being spied on. 

    16. Autocorrect doesn’t work well 

    Autocorrect is a finicky beast on the best of days. However, if it starts acting strange or lagging, this may be the result of a keylogger at work. After all, what better app to steal your inputs if not the keyboard or autocorrect?

    Can someone spy on you when your phone is off?

    Yes, there are ways to spy on you via your phone, even when it’s turned off. In the Snowden days, there were rumors of NSA software called “The Find” that could tap switched-off phones. 

    But a more likely situation – and something that a regular hacker could do – is making your phone appear turned off when, in truth, it’s just pretending to be. Locking the screen, blocking calls, and turning off notifications, makes it possible to simulate a switched-off state. 

    This can’t be done remotely – someone or something has to compromise your phone in the first place. Only when malicious software has been placed on your phone can such tricks be accomplished. 

    Another related subject is Airplane Mode. For iPhone users, turning on Airplane Mode doesn’t mean the phone is immune to tracking. An iPhone will still ping other iPhones via Bluetooth as part of the system that makes Find My Device and Apple AirTags work. So while this doesn’t allow hackers to access your files, they can still track your location. 

    How can someone remotely access my phone? 

    The best way to hack a phone is by physically installing one of the monitoring apps from the app stores. But there are other things to be on the lookout for if you’re worried that someone may hack your phone. Your cell phone can get compromised by one of these other means: 

    • Suspicious emails: just as you shouldn’t open suspicious email links and attachments on a computer, neither should you do so on your phone. 
    • Compromised apps: maybe you downloaded some third-party app that wasn’t vetted by the app store or got a free VPN, 38% of which were found to contain malware (at least on Android devices). Once again, the infection is happening with your help. 
    • Jailbreaking: mostly an iPhone issue – if you want to install third-party apps on Apple products, you need to jailbreak them…which opens you to a world of risks. 
    • “No-Jailbreak Apps:” a rare category of Apple monitoring apps that spy on you by accessing your iCloud updates. 

    Sure, all of this sounds terrible. But there are ways to remove spyware from your device. 

    How to remove spy software on Android 

    Checking for apps: 

    It is possible that a spyware app on your phone is installed with a name like “spy,” “monitor,” or other similar unsubtle words. Here’s how you can detect them:

    1. Go to Settings;
    2. Choose Applications;
    3. Find either Manage Applications or Running Services;
    4. Check for suspicious apps

    Don’t know whether the app you found is suspicious or not? Google the name! If it’s an incompetently named spy app, uninstall it. 

    An alternative method is to root through file sections and directories to find ones titled something suspicious. Here’s how it’s done: 

    1. Find My Files or an equivalent app on your device;
    2. Access internal storage (phone or SD);
    3. Choose Android;
    4. Choose data;
    5. Browse around for folders with suspicious names. 

    What about an iOS device?

    How to remove spy software on iOS devices

    The no-Jailbreak apps like mSpy depend on spying on the stuff you upload on iCloud. The easiest way to fix them is to change your iCloud password. 

    Now, for real spying, an iPhone must be jailbroken. And even then, the apps need a third-party installer to work. Check your phone to see if you have apps like Cydia or Icy. If they’re there, your phone is jailbroken. 

    You can also see if all the apps installed on your device exist on the Apple Store. If any of them don’t, your phone is jailbroken.

    How do you fix that? By updating to the latest iOS version via iTunes

    Codes to check if your phone is tapped

    Unstructured Supplementary Service Data (USSD) codes are short codes that allow you to access certain network functions directly – and they can be mighty handy for seeing if something is amiss. Just enter the full code – yes, with the *’s and #’s – and tap the call button. It may not work with all phones or operators. 

    *#62* – this checks for redirections. If you see another phone number, your calls may be redirected to it. However, it is smart to check that phone number online – it may turn out to be your service provider’s voicemail function. 

    If it’s not, dial ##002# to reset it. 

    *#21# – checks for diversion, which is similar to redirection. 

    How to reset to factory settings on Android and iPhone

    This is the nuclear option for removing spy apps. It will wipe your phone, which means your settings, apps, contacts, media, and other stuff will be gone. Make sure to back up the important things before a factory reset. 

    Factory reset on an Android device

    1. Make sure the phone is well-charged or plugged in;
    2. Enter the Settings menu (usually by swiping down on the main screen and then selecting the appropriate button);
    3. Tap System;
    4. Tap Advanced;
    5. Go to Reset Options;
    6. Tap Erase all data (factory reset);
    7. Tap Erase all data;
    8. Enter PIN if prompted;
    9. Tap Erase all data;
    10. Watch the process happen.

    Factory reset on an iPhone

    1. Go to Settings;
    2. Select General;
    3. Tap Reset;
    4. If you have an iCloud backup, you’ll be asked if you want to update it. It’s a good idea, so tap Back Up Then Erase;
    5. If you set a passcode, you’ll be asked to enter it;
    6. Tap the Erase iPhone option in the warning window;
    7. Enter your Apple ID password;
    8. Wait for the phone to reset. 

    Factory resets are the most extreme option for removing spy software. But it’ll make sure your phone is fresh. And now that you’re spyware-app-free, here’s how you can protect yourself from future cell phone spying.

    How to prevent spyware from infecting your phone

    Here are a few tips on preventing your phone from being riddled with spyware:

    1. Keep it updated: Phone OS and various app updates happen for a reason – and sometimes, that reason is filling a known security gap. 
    2. Use antivirus software: a simple antivirus can easily detect many spy apps. Having one is especially recommended for Windows and Android users as viruses, malware, and spyware are more common on these OS.
    3. Don’t go third-party: enabling unsupported apps on Android devices or jailbreaking iPhones makes your phone a bit more vulnerable to exploitation. 
    4. Don’t leave your phone unattended: locking your screen and never separating from your phone is the safest way to keep your smartphone from being hacked. 
    5. Be careful online: shady websites and suspicious email attachments (or URL links) can be dangerous. So don’t click on what you don’t know. 
    6. Use a Virtual Private Network (VPN): VPNs sometimes offer additional features – like Surfshark VPN’s CleanWeb, which keeps your phone safe from over 1,000,000 known malicious sites. 

    It’s a short list, but these steps will significantly improve your phone’s security and  protect it from being hacked (spyware is just one form of hacking). If you’re interested in that, check out our article on how to know if your phone is hacked.

    How can you tell if someone is spying on your phone?

    A few common conditions, like your phone heating up or restarting for no reason, can help you determine whether your phone has been compromised. 

    Is someone watching me through my phone?

    Right now, in real-time? Probably not. State security agencies usually collect data for analysis instead of looking at it live. 

    Can someone spy on your phone without you knowing?

    Yes, if they had physical access to your phone and installed monitoring software.
