Motorola X4 has “Dual Autofocus Pixel technology,” according to the website. Dual Autofocus is different from Laser Autofocus. Dual Pixel Autofocus (DPAF) does not use a laser to focus on objects. Most smartphones have DPAF, while some smartphones have laser autofocus. The imaging sensor in the camera has diodes that are sensitive to light. Each of the diodes detects light. The cumulative effect of the diode gives the final picture. So there aren’t any lasers involved in this.
Laser autofocus uses a laser beam to calculate the distance of an object from the camera lens. The laser emits from the phone, detects the object, and reflects back. It helps the camera focus on the object and provides a clear image. While the laser autofocus is not found in Motorola X4, the technology is safe to use. It does not affect the eyes or the skin. Your eye may feel irritated if the laser is exposed for too long.
To check if the phone has laser autofocus or not, you can simply go to Motorola’s website and search for the product.
