Lightning connector and flat replaced but now a noise on the mic
Hi all. A store replaced my lightning connector+flat from my iPhone cause the original stopped to charge. After this all recorded sounds on whatsapp, voice memos, facebook and phone calls using the regular cell phone and whatsapp audio are generating a noise on the background of the audio. Using the headphone/mic from Apple nothing is recorded. Recording videos using the front and rear camera, the noise is not recording. Only on what I described.
You can hear the noise on a voice memo on a YouTube video that I did. The first audio is the original recorded. The second on the video I just amplified for better hearing.

Any idea of the problem? Thanks.
Update (10/13/2022)
@strongbow I tried to clean the grills, but I think the correct possibility is the "1". Cause I can try to use the iphone near from my face, on the normal position, without touch the sensor with the screen on and the sound is horrible. The answering machine here when I call to test turn off due the sound so low.
The audio message created on the whatsapp before the replacement has a good waveform but after the replacement is horrible. Here is the screenshot.
Es esta una buena pregunta?
