Can we reproduce this on Flame?

Comment 3

[Diego Marcos [:dmarcos]]

No. Flame front camera does have face tracking because the HW doesn't support focus regions.

I meant Flame front DOES NOT support face tracking

Comment 5

[Diego Marcos [:dmarcos]]

If any camera support both face tracking + focus regions the feature will be available automatically

Comment 6

[Hema Koka [:hema]]

If Face Detection and Focus regions are both available, face tracking will be enabled automatically. Otherwise it is disabled. 

Bhargav: Can you confirm if QRD supports focus regions on front camera?

Comment 7

[Diego Marcos [:dmarcos]]

I don't have a QRD device but my guess is that either face tracking or focus regions are not available for the front camera so the feature is not available.

Comment 8

[Diego Marcos [:dmarcos]]

On flame we could paint the circles around the faces but we would not be able to focus on them. It would be misleading for the user.

Comment 9

[Lawrence Mandel [:lmandel] (use needinfo)]

Clearing the nom on the invalid bug. Comment 6 has justification.

Comment 10

[Inder]

Hema -- we confirmed that 8x10 QRD has fixed focus sensor so it won't have face detection circles. We are trying to verify on 8926.

Comment 11

[Pooja]

On 8x26 targets the front camera focus mode is fixed and so focus region in not supported.
