Does the mobile phone strongpoint represent poor quality?

This situation does not mean that the quality of the mobile phone is not good.

When shooting indoors or at night, the lighting is usually powered by alternating current, and its frequency is 50Hz or 60Hz.

If the shutter speed of the camera is not synchronized with the light frequency, stroboscopic phenomenon may occur. This situation does not necessarily mean that the quality of the mobile phone is not good, but that the camera cannot match the frequency of light under certain conditions.
