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.

That noise, or lack of for the first 7 seconds is white noise from what I can tell.

The hot phone is a different issue. Did you install a backup? If so, maybe restore phone to new and see if it still gets hot. You could have an issue in your backup.

the sound from my video is white noise?

I set it up as a new iphone after purchase(1 week ago), so no backup. I restored it about an hour ago, so lets see how it behaves.

like someone else said above. its probably something when you restored from a back up. it happened to me before, my phone would get so hot i couldn't hold it. i did a DFU restore, and set it up as new (do not restore from a backup), logged into iCloud so i can get my contacts, and photos in iCloud and re downloaded the apps i wanted again from the purchased section and it was fine again. what you'll lose is your texts and app data.

it also sounded like white noise to me. DFU restore and plug it into your computer and redownload ios.

Uhm...yeah...if it's hissing, it's hissing. If it's not, then it isn't.

Why ask a random Internet forum about your phone?!?

my big problem is not that with hissing but with how much my 7+ warm. I think they are related or i dont know. im just upset of how it gets hot even under light use.
