Yes, hackers can see your iPhone screen, but it's typically difficult and requires powerful spyware, a compromised Apple ID, or tricking you into installing malware through phishing or malicious apps, often by exploiting software flaws or gaining physical access. While iPhones are secure, they aren't invincible, and sophisticated attacks can allow remote access, screen recording, and camera/microphone control, so keeping iOS updated and being wary of suspicious links is crucial for protection.
Phone mirroring broadcasts what you see on your screen to another device. If done without your consent, it can reveal sensitive information — your private messages, passwords, and other personal data — to someone else.
7 signs your iPhone has been hacked & how to verify it
Use a Privacy Filter Screen
On an iPhone, dialing *#21# is a USSD code used to check the status of your unconditional call forwarding, revealing if your calls, SMS, or data are being redirected and to which number, without actually changing settings; it's a simple privacy check to see if someone has secretly set your phone to forward everything, though it doesn't detect advanced spyware. Dialing this code brings up a message from your carrier about your call forwarding status, often showing "Disabled" or a specific number if it's active.
Run a malware scan
iPhones don't warn users about malware with pop-ups. If you notice signs of malware on your smartphone, run a scan with a trusted tool like Norton Mobile Security. This is the most reliable way to detect malicious software that may have bypassed Apple's defenses and remove it from your device.
Three-finger gestures on iPhone primarily activate accessibility features like VoiceOver (for screen reading and navigation) and Zoom (magnification), allowing scrolling, zooming, and text manipulation (copy/paste/undo) with specific taps and drags, though some text actions work without VoiceOver enabled for quick editing. Common gestures include three-finger double-tap to toggle VoiceOver speech, triple-tap for the screen curtain, and pinching/spreading with three fingers for copy/paste actions, notes this YouTube video.
Keep an eye out for significant changes in device temperature and battery life, as these might indicate remote access. During calls, pay attention to any strange noises or voices, as they could indicate unauthorized call monitoring or recording. Be cautious of increased service messages and pop-up ads.
Can hackers see me through my phone screen? They can't see “through” the screen, but if you unwittingly download spyware to the device, they could see what you see.
*3001#12345#* on an iPhone activates the hidden Field Test Mode, a diagnostic tool for network engineers and power users to see detailed cellular data like signal strength (dBm), cell tower info, and network quality, accessible by dialing the code in the Phone app and pressing call, often after turning off Wi-Fi for accurate cellular readings.
To check for the most basic methods of mirroring, look to your phone's top tray. You may see an icon from (depending on the devices involved) Link to Windows, AirPlay, or Phone Link. It's also a good idea to monitor for third-party tools like AirDroid and TeamViewer and check to see whether debug mode has been enabled.
How to Know if You're Being Monitored at Work
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#*#*
You can double-tap or triple-tap the back of iPhone to perform actions such as taking a screenshot, turning on an accessibility feature, running a shortcut, and more. Go to Settings > Accessibility > Touch > Back Tap. Choose Double Tap or Triple Tap, then choose an action.
Messages automatically uses the following screen effects for specific text strings:
Control iPhone with a pointer device
Go to Settings > Accessibility > Touch > AssistiveTouch. Turn on AssistiveTouch.
Signs your phone has been hacked
Unknown apps: If you see any unfamiliar apps on your phone that you don't remember installing, this could mean a possible compromise. However, don't confuse these apps with bloatware, which are the unnecessary pre-installed apps that come with your phone.
On an iPhone, dialing *#21# is a USSD code used to check the status of your unconditional call forwarding, revealing if your calls, SMS, or data are being redirected and to which number, without actually changing settings; it's a simple privacy check to see if someone has secretly set your phone to forward everything, though it doesn't detect advanced spyware. Dialing this code brings up a message from your carrier about your call forwarding status, often showing "Disabled" or a specific number if it's active.
Apple notifies you (notification or email) about account activity that you don't recognize (for example, if your Apple Account was signed in to on a device that you don't recognize or your password was changed but you didn't change it).
##002# cancels all forwarding on many GSM networks worldwide. Dial ##002# and press call. You'll usually hear a confirmation message.
Call barring allows you to block certain types of incoming or outgoing calls. Dialing *#33# displays your device's current call barring status. If you're receiving excessive spam calls, enabling call barring can help prevent unwanted calls, including those from potential hackers.
