Question about Dual Electronics CECT P168 Cellular Phone
I have a cect i9+++ so i think anyways but it has an ear piercing buzzing noise when others try to hear me wondering if anyone else has the problem or knows what to do about it thanks
This problem exists actually at all phones of this kind. The microphone replaced to a more sensitive type, but the firmware is not tuned for it. In this case, the electromagnetic field of the flash memory controller near the microphone generate this noise. If you pull out the mic from its case, the noise clams up immediately. This problem could be solved by a new firmware. The voulme of the microphone can not be adjusted through the phone's UI.

I had this same problem with my daughters telephone i9+++. The microphone is seated in a little place in the metallic frame. I has a small hole for the sound. I made the hole a little bit bigger with a miniature metallic philips screw driver and seated the microphone again to its place. And voila....buzzing noise disappeared totally....at least for now....

Did anyone solve the "buzzing" noise that others hear when using a CECT phone? I see hints that you can adjust a parameter to solve, however, I can not find the specifics. Anyone know?
