It's difficult to tell if your phone is being tapped, but there are some signs that someone is listening in on your conversations or watching your activity:
Static, clicking, or echoes are examples of unusual background noise during phone calls.
Even when you're not using your phone much, the battery drains faster than usual.
You discover unfamiliar apps or files on your phone that you did not install or download.
Your phone acts strangely, such as turning on or off by itself, sending texts or making calls without your knowledge, or automatically opening apps or websites.
You receive strange or suspicious text, email, or social media messages.
Even when you're not using it heavily, your phone frequently overheats.
Even when you're not actively using your phone, you notice an unusual amount of data usage or network activity.
If you suspect your phone is being tapped, you must act quickly to protect your privacy and security. Here are some things you can do:
Using a reputable antivirus app, scan your phone for malware.
Update the operating system and security software on your phone to the most recent version.
Change the passwords and security settings on your phone.
Avoid using public Wi-Fi networks because they can be hacked.
Open email attachments with caution and avoid clicking on links from unknown or suspicious sources.
If you are still concerned, you should seek the advice of a professional security consultant or a law enforcement agency.
