For instance, Oppo is utilising its digital health lab platform with one of the ColorOS 

features on the Find X6 Pro to provide you improved sleep tracking directly 

from your phone without the use of other devices.

In order to give you a complete picture of your sleep pattern from your phone alone,

, the installed Health app where the sleep tracking option is located uses a combination 

sensing components like the accelerometer or mics to track your body movements, 

the pulse or breathing rate, and the snoring sounds.
