The Find X6 Pro from Oppo includes a brilliant security-focused function that improves caller privacy.

When we tested it against the earpiece of its predecessor,

When we tested it against the earpiece of its predecessor,

[{"selector":"#anim-9a191b97-9bb7-4eea-ac8a-b607df0f153b","keyframes":{"opacity":[0,1]},"delay":0,"duration":1200,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-79c465ed-73f7-4423-88f8-559fe51dbde9 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(0%, 0, 0) translate(25%, 0%) scale(1.5)","translate3d(0%, 0, 0) translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"fill":"forwards"}]

we could barely make out an incoherent thing from the same spot near

[{"selector":"#anim-3a391d61-eb07-434b-b6c3-3dafbc754791","keyframes":{"opacity":[0,1]},"delay":0,"duration":1200,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-c937c28e-61c4-4fd4-bb09-9466580e14b8 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate(0%, 0%) scale(1.5)","translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

the phone where we were sitting while the other phone was blasting an audible conversation at that volume.

[{"selector":"#anim-e63e360e-150b-4516-a6b2-614a86446c28","keyframes":{"opacity":[0,1]},"delay":0,"duration":1200,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-9539d732-0621-456c-a34f-cc7dd1da7c4e [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(0%, 0, 0) translate(25%, 0%) scale(1.5)","translate3d(0%, 0, 0) translate(0%, 0%) scale(1)"]},"delay":0,"duration":2000,"fill":"forwards"}]

It enhances the sound direction from the earpiece for a greatly reduced spillage.

Just keep in mind that it only functions at volume levels 8 and lower, and that it is clearly visible while dialling.
