Internet Trick: Can AluminumBlock Phone Spying
Elias, who typically resorts to easier methods to disrupt wireless signals, can use aluminum foil to cut off connection to smartphones by wrapping them tightly. Aluminum limits the electromagnetic waves reaching the device by reflecting or absorbing some of them, according to the "Faraday Cage" theory. This method may fail if there are small gaps, and experts recommend placing the phone inside a plastic bag before wrapping it in aluminum to prevent damage. Although this technique is effective at blocking signals, simpler alternatives such as activating airplane mode are available. It is also advised to rely on built-in security features to protect privacy rather than depending entirely on aluminum covers.
