i am on the latest Mahdi-Rom (17/08) with my LG G2 D802 and Stock-Mahdi Kernel.
When I call someone, it makes a very loud noise at the beginning of the call. This noise is really loud if using headset or bluetooth (the noise is also appearing when not using headset/bluetooth).
I am pretty sure I am not the only one with this issue, however I could not find any way to solve this.
Is there some fix? Do you need further information?
