Yes. Chromatic aberration is caused by the lens, not the sensor.

Different wavelengths of light are bent by different amounts as they pass through the lens, so red, green, and blue light do not all focus at exactly the same place or with exactly the same image size. By the time the light reaches the sensor, the color channels are already slightly misaligned, which appears as color fringing.

The Bayer filter does not prevent this. It only determines which color each photosite measures; it does not correct the lens’s focus errors. The camera then reconstructs a full-color image from those sampled color values, so any lens-caused misregistration between colors remains visible in the final photo.

This is not specific to smartphones—any camera lens can show chromatic aberration. Lens designers reduce it with optical design, but they cannot eliminate it completely. In very small phone lenses, correction can be especially challenging because of size constraints, though software may reduce visible fringing afterward.
