Apple 1 1 What if the camera is dusty?

Take Apple 1 1 and iOS 14.2 systems as examples.

Dust enters the camera of Apple's mobile phone. If only dust enters from the outside, the user can choose to wipe the camera with a fine cotton swab. The cotton swab is small and can be rubbed into the corner.

If the camera is found to have dust, you need to send the mobile phone to Apple for after-sales maintenance, and ask professionals to clean up the dust.

Precautions for using mobile phones:

There are two kinds of receivers and speakers, one is for * * * and the other is independent. Early mobile phones were all * * * one phone, with one advantage, the receiver ringing, and the disadvantage was that the speaker was low, which was difficult to do, because it was necessary to give consideration to both.

After the later separation, the sound of the receiver becomes obviously smaller. Moreover, once the sound is broken, the rupture of the diaphragm cannot be recovered. By default, the volume of the receiver is two full bars, then one bar is adjusted after one week of use, and so on until the maximum volume is reached. So is the speaker. In this way, after a month of use, the mobile phone can generally reach the maximum volume, without breaking the sound and causing serious injuries.
