This is for the iPhone and Android. Screenshots are from iPhone 14 Pro running iOS 16+

For better or worse, our smartphones are always with us, so if someone taps into the camera or mic, it’s a serious problem. But how can you tell if your phone is being tapped, and how do you protect yourself?

How to Tell

If someone gains access to your phone they can potentially send fake emails, read your personal messages, record your calls, and all sorts of other nefarious behavior. But can you even tell if someone’s hacked your phone? Let’s explore a few ways to find out.

1) Battery Life is Failing

If your phone constantly overheats seemingly for no reason and the battery drains quickly without any apparent cause, your phone might be hacked. Malicious software running in the background can drain your battery without any apps running and can be anything from malware that’s reading your email to call-recording spyware.

If you are already a heavy phone user, your battery probably gets hot anyway. Streaming video or playing games for long periods of time, for example, will cause your phone to heat up which is pretty normal. If you have not been using your phone a lot and the battery still heats up or can no longer hold a charge, you might want to check for malicious software.

To do that, check your battery settings. On either an Android or iPhone you can see which apps are using the most battery by going to:

Settings > Battery

where you will see which apps are using the most power. If there are apps on that list you do not remember installing, or a third-party app that should not be using much power, uninstall them immediately. Refer to the below image:

2) Weird Noises

A high-pitched hum or strange, pulsating static on the line could be a sign your calls are being recorded. If you hear static or other strange sounds like clicking or beeping even when you are not calling someone, that’s another sign, especially when your phone’s been tapped by the police.

Hearing these sounds once or twice at random is probably okay, but if it happens consistently, check your phone. You can try using a sound-bandwidth sensor app from another phone set to a low frequency. If it picks up several sounds over a minute, your phone may be compromised.

3) High Data Use

Spyware and malware will routinely use a lot of data; constantly sending information back to whoever hacked your device. If your location or data icons at the top of your screen regularly move or light up, that could be a sign someone is sending data from your phone or controlling it remotely. Higher than normal data use can also show up as a higher phone bill if you do not have an unlimited data plan.

iPhones and Android phones both let you check your data usage to see if your phone is (possibly) tapped. To do it on an iPhone, go to:

Settings > Cellular

See the below image:

On Android, go to

Settings > Network & Internet

It may also be under:

Connections > Data usage or > Mobile data usage.

4) Unusual Activity

If your phone has trouble shutting down, that could be a sign it’s being tapped. Randomly shutting down on its own is another sign of trouble. When turning off your phone, check to see if the backlight stays on even when the phone is powered off or if the shutdown fails altogether.

Other strange behaviors your phone could exhibit if it’s been compromised include popup ads, the screen lighting up at random, and messages you do not recognize that push you to follow unfamiliar links. Also, performance often slows way down.

Watch out for your camera or mic turning on randomly. If you keep seeing the camera light go on when you did not open an app that uses the camera, it could be a sign your phone’s been hacked. Some malicious software lets hackers access your camera without turning the light on, so always dig deeper if you think something’s fishy.

5) Websites Look Strange

Some forms of malicious software can infiltrate your browser, showing you a fake web page that looks legitimate, then harvesting your login credentials when you type them in. If you are browsing on your phone and the web page you are looking at acts strange or does not look quite like it’s supposed to, close the browser and check your phone for malware by scanning it or taking it to a professional.

Protect Your Phone From Being Tapped

If you want to make sure your phone is never compromised, avoid downloading any apps that are not from the Google Play Store or Apple’s App Store. Even when using the mainstream app stores, though, do a Google search of the app and the developer to double-check that they are on the level before you download; bad apps can and do occasionally get past their vetting processes.

Download trusted anti-malware and antivirus apps and use them regularly. If you can afford a premium subscription, do it. If not, there are some great free options available.

Using a VPN to obscure your true IP address can make it harder for someone who’s trying to track you to pin down your location. If you can, try a few out and use one regularly when are in public or on an unsecured connection

.You can also check and see whether your calls and messages are being forwarded to other devices using Man-Machine Interface (MMI) codes. They will be different depending on the network but can allow you to discover and cut off any unauthorized forwarding. To use them, dial the desired MMI code with your keypad, then hit the call button.

If you are on a GSM network (like AT&T and T-Mobile):

• *#002# — Lists all call and data forwarding settings
• ##002# — Clears all call and data forwarding settings

If you’re on a CDMA network (like Verizon and US Cellular):

• *72 — Lists all call and data forwarding settings
• *73 — Clears all call and data forwarding settings

Unfortunately, MMI codes only work on Android devices, but you can use the USSD (Unstructured Supplementary Service Data) code *#21# on an iPhone to check your call forwarding status and see if your calls are being forwarded anywhere else.

If you are done your due diligence but you are still experiencing these symptoms, take your phone to a professional. Odds are they will have the tools to scan more deeply and remove any bad software that could be causing the problem.
