Engineers have learned how to control the smartphone screen without contact.

Chinese and German engineers created the GhostTouch device. It can remotely simulate touching the touch screen with your finger. The device works due to the design features of touch screens and their susceptibility to electromagnetic interference. Vulnerability can also be exploited by criminals. Theoretically, they will be able to unlock a smartphone, connect to Wi-Fi, open malicious content, or answer a call from their number for wiretapping. But scientists believe that the technology is unlikely to be widely used - there are certain difficulties. At the same time, in the future, smartphone manufacturers will be able to develop algorithms for recognizing false touches.
