When unboxing the Xiaomi Night Light 3, you can notice bubbles and a worn appearance on the logo protective film. This film is primarily designed to protect the lens from scratches caused by friction with the PE bag during packaging and transportation. Since the film is applied manually, much like protective films on phones, it is normal for some bubbles to appear. These bubbles do not affect the functionality of the night light.
For optimal sensing performance, it is recommended to remove the protective film during installation and use. This ensures the sensor operates at its best and the light remains clear and effective.
