Buzzing sound

[Android Central Question]

2 days ago i noticed that when i was in a voice call the person on the other line said that their was some kind of buzzing or static, so i tried removing the headphones and blowing in the earphone jack, and the buzzing was still there, so then i recorded a video and you could hear the static/buzzing noise in the background. yesterday it went away but now its back. when i just record an audio the buzzing isn't there only in voice calls and video recordings, i also tried a different pair of head phones and nothing changed, i even tried recording a video without headphones and the buzzing was still there. and im not really sure how i fixed it last time. i have a umidigi f1 play

Have you made sure all microphone and speakers are clean , if so try safe mode if still happening.I'll leave a link to register so you can communicate here , as a guest account you can't.https://forums.androidcentral.com/showthread.php?t=409154

Welcome to Android Central! So does this only happen when using headphones, or also when using the primary mic or on speakerphone?
