How does Huawei mobile phone detect whether the hotel has a camera?

The first step is to open the membership service in the mobile phone, which is an application that comes with the mobile phone.

Step 2: After opening the membership service, in the shortcut service, click More, and after entering, select Intelligent Detection.

Step 3: After entering, click Manual Detection, and you can see that both front and rear cameras can be used for detection.

The fourth step is to check the front camera first, touch the picture to start the test, and automatically take pictures during the test to see if there is an image. If there is an image, there is no problem.
