    Hello everybody,

    I have a question since i bought my new at&t black matte 7+ from apple store. I heard that a lot of people are affected by the hissing/buzzing(whatever you want to call it) sound. Can you help me, to check if my phone has this problem too? When i put the phone with apple logo near my ear, i can hear some strange sounds (cant describe them). Its like the sound from a working hdd i guess. But that sound i can also hear on my old 6s , even louder than on 7+.

    Is there another way to check the problem? I try to record a video in a silent room but i cant tell if there is a hissing sound on it,because its normally to hear some strange sounds when you record in a silent room and listen it with max volume.

    Here is a link when recording a video in 4k. From sec 8, i put my finger on the speaker near the front camera.

    I haven't heard it in mine, but i hear it has to be super quiet to hear it. During a call listen to the back of the phone. Apparently, that is where a lot of people notice it, because it is coming from the coil.

    Coil whine is always possible but I've had two different 7+s and haven't heard it on either. If you're having a problem you'll hear the hissing sound. If you don't hear anything there's nothing to worry about.

    that's the problem, that i can hear some noises, but i dont know if these are normal sounds or its the hissing/buzzing etc sound. I can hear these sounds on my old 6s too, louder.

    Im experiencing another strange behaviour..my phone gets hot after 15-20 mins of working (light use, fb,whatsapp,instagram. Nothing that can make it overdrive).

    When your phone gets hot is the perfect opportunity to check. Put the back of the phone up to your ear and you'll hear it then. It's the only way I'll hear it on mine.

    so youre phone gets hot too? i ran a benchmark 1 minute ago, and i heard the coil whine/hissing/buzzing sound. It also gets so hot under the back camera that is was so unpleasant to keep it in hand.

    Do you have a case on yours? I have the MB 7 plus 256 gb. With att. I put a black speck case on mine and I haven't noticed any warmth on it but it just might be because of the case.

    I have a 128 GB matte black 7+ on at&t and have yet to hear a hissing noise. Maybe I'm just not as observant as others.

    Sometimes it seems to be warm even though it's in the case when I'm gaming hard on it. I didn't get AppleCare plus on it because I usually don't need it. Wondering if I should take it in to be checked or just leave it and use it.

    Definitely can hear it on my Plus. It sounds more like a computer making noises than a hiss though. I can hear it sometimes if I am in a quiet room holding the phone up to my ear to listen to someone on the phone. It doesn't bother me that much I just think it's interesting
