Muka Keliru

A yellow face with open eyes and a skewed frown, as if scrunching its cheeks or chewing its lips. A look of feeling unsure.

While it can convey confusion or hesitation, it is also commonly used for slight sadness, disappointment, and frustration.

Huawei's design for this emoji includes a ❓ Red Question Mark.

Samsung previously included raised eyebrows, as did Microsoft along with a rotated S-shaped mouth, à la the :S emoticon. Google’s design also previously included a furrowed brow.
