Hi, I have strange problem after replaceing my Iphone 6 plus to new cover/housing from china. After this during a conversation with someone after some 30 sec I heare a high level signal like some rezonance. For example same signal when microphone is to close with speaker. I can stop it when I uese some power on the back of the housing or when I will change speaker to loud mode and than back to normal for some time. I replaced speaker for ny and still the same …. ANY IDEA ??

Hi, Did you make sure to transfer the gaskets at the bottom of the housing? If you haven’t this may be the issue, or could be the part you transferred over. Please make sure you transferred over the mesh and the gasket at the bottom. :-)
