Does anyone have buzzing noise issue with Galaxy S7? After calling using the earbud included, if I play music, then there is buzzing noise not only through earbud but also through the internal speaker. I contacted Samsung rep. and he told me that restart the phone. After restarting, the noise disappeared, but once I call using earbud, then there is a noise again. Rep. told me to do factory reset. I've done it, it went back to normal. but again, after calling, the noise comes again. Finally I exchanged the phone. It seemed to be okay, but now, I didn't even using the earbud for calling, but at some point, I hear the noise again. I'm wondering if anyone has the same issue. no rooted.
