Can hotspots see interconnected content?

Open the hot spot. After someone connects, as long as the other party doesn't steal mobile phone information, they won't see the information in your mobile phone.

Mobile phone wifi hotspot is a technology that converts GPRS, 3G or 4G signals received by mobile phones into wifi signals and sends them out, so that portable devices such as mobile phones, tablets or notebooks can pass through wireless network cards or wlan modules.
