The CMF Phone 1 unexpectedly revealed a "see-through" camera feature, as users discovered that the depth sensor could be used to see through certain objects. This occurred due to the depth sensor lacking an infrared light filter, which can sometimes reveal the internal structure of thin or semi-transparent objects.

A user accessed the CMF Phone 1's depth sensor by using a third-party app in developer mode, which allowed them to bypass the normal restrictions and gain access to the sensor's output2. This revealed the depth sensor's ability to see through certain objects due to its lack of an infrared light filter.

The CMF Phone 1's depth sensor could see through certain thin or semi-transparent objects, such as the back of a TV remote, due to its lack of an infrared light filter. The IR light in the sensor can sometimes reveal the internal structure of these objects. However, the company will restrict third-party apps from accessing the depth sensor's output within a week for privacy concerns.
