3.30 Why can I hear noise or current noise when I play
songs in speaker mode at the minimum volume?
1. The speaker is a large-power component, which is driven by a PA. When the volume is
reduced to the minimum, the PA is still working and outputting certain noise floor (similar to
a home theater at the minimum sound volume). When your ear is close to the speaker, you can
hear that noise, which is the noise floor of the speaker circuit. It is recommended that you do
not place your ear close to the speaker to protect your ear.
2. Your phone adopts the third-party sound effect commissioning algorithm in terms of the
speaker sound effects. When the volume is set to the minimum, the algorithm filter's deviation
will be output through the speaker, that is, the current noise, which is a normal phenomenon.

the video is saved to the microSD card, you can copy the video to the internal storage and
play it to check whether the microSD card is damaged.
