strange signal/rezonance or rezistance after cover/housing replacement
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 ??
Is this a good question?
