-

FACE_AUTH_TIP_TOO_DARK

-

2

-

The obtained facial image is too dark due to low illumination.

-

FACE_AUTH_TIP_TOO_CLOSE

-

3

-

The face is too close to the device.

-

-

4

-

The face is too far away from the device.

-

FACE_AUTH_TIP_TOO_HIGH

-

5

-

Only the upper part of the face is captured because the device is angled too high.

-

-

6

-

Only the lower part of the face is captured because the device is angled too low.

-

FACE_AUTH_TIP_TOO_RIGHT

-

7

-

Only the right part of the face is captured because the device is deviated to the right.

-

FACE_AUTH_TIP_TOO_LEFT

-

8

-

Only the left part of the face is captured because the device is deviated to the left.

-

FACE_AUTH_TIP_TOO_MUCH_MOTION

-

9

-

The face moves too fast during facial information collection.

-

FACE_AUTH_TIP_POOR_GAZE
