It’s about the always-on function. It allows the front camera to always be on alert. For example, helpfully unlock your phone by your face before you even pick it up, or instantly lock it if your face disappears from the camera’s field of view.
The Verge noted that this feature sounds intimidating and may be detrimental to privacy. Of course, being able to unlock the phone with just a glance can be convenient, especially if your hands are dirty. However, privacy is also worth considering.
Qualcomm views the always-on camera as the always-on microphones that have been used in our phones for many years. This option is used to listen to voice commands. Fortunately, the company has assured that users will be able to disable the always-on camera feature. The main thing is that all people know about it.
