The face cameras of mobile phones are all on the front camera.

Knowledge expansion:

Face recognition mobile phones have been widely used by major mobile phone manufacturers as a popular unlocking program. Speaking of face recognition technology, this is not a new thing. This technology has existed as early as the Android 4.0 period. Due to the immaturity of the technology, manufacturers simply use ordinary software and cameras to conduct image-level analysis to safely "swipe faces" "The above technology is really difficult to achieve. With the development of technology up to now, face recognition has broken away from the two-dimensional imaging principle, and three-dimensional modeling technology has begun to turn around. The new technology is used in unlocking mobile phones, and its safety and speed are guaranteed. With the popularity of full-screen mobile phones and the contradiction between front-facing fingerprint unlocking, face recognition unlocking is becoming more and more important.
