6S+ chirp before connecting a call

    I am getting a very brief but loud chirp/squeak noise from the earpiece speaker on my 6S+ both when making and receiving calls. I hear the noise and then the call connects immediately afterwards. I'd say it happens the majority of the time, but occasionally, the keypad screen glitches/flashes and then the call connects without the noise. Bizarre.

    I've tried making/receiving calls with/without bluetooth, wifi, VoLTE, etc. enabled but nothing seems to make a difference. Anyone else experiencing something similar?

    Had this three times today. Once in the middle of a call. Ear-piercing. 6s T-Mobile.

    Obviously not for you, JAT, but otherwise: I have a network extender for Verizon, and yes it makes a chirp/connecting sound right before the call is taken to let you know that it's using that. Are you in an apartment? Maybe a neighbor has an extender. By default, any Verizon customer can connect to it unless the owner turns it on by a phone # basis.

    Mine were all on LTE today. The one in the middle of a call could have been when switching from a wifi call to LTE, not sure.

    Mine were piercing chirps like a feedback screech in a PA system. Yours sounds like it might be milder.

    Mine were all on LTE. I tried disabling cellular data as well, no change.

    Here is a short video, apologies for the quality but I think you can see/hear what I'm referring to. The first 3 call attempts begin with the chirp, the fourth has the screen glitch/flash with no chirp.

    Oh that is different. You know what, I initially got that too when I was trying to activate the other line. It apparently wasn't activated yet, and made that chirp noise and ended the call right away. I guess it went away once I was officially activated with Verizon and didn't think much of it. It's wouldn't be wifi calling would it?

    Nope - wifi calling is disabled, and I've tried every combination of data and services on/off I can think of. Nothing seems to affect it.

    Could be electric isolation issue... There have been reports about headphone jack buzzing also.

    :( Sorry, that's all the tips I have :|. I have two last things:
    1) Take a backup and set the phone up as new. See if you get the chirp then? If not, there's something with your backup. Maybe even simply restoring from that backup again will fix the problem.
    2) If you are close enough, maybe take it to an Apple store to see what they say. Obviously not ideal but not sure what else it could be. Or it seems like this is happening to a lot of Tmobile people, maybe try calling them (I doubt they'd even know what you're talking about though).

    That video seems similar to mine. They were so sudden and new I didn't really figure anything out. I've never heard it before. 3 years on vzw, now 1 on T-Mobile. iPhone 4,5,6 before, now it shows up with the 6s.

    Just tried a few calls both on lte and on wifi, no chirp so far today.

    I'm wondering if it is a switch between connections. Wifi to lte, or lte to 4G, or between lte bands.

    There is no plastic on the phone, but it is in a Catalyst waterproof case. I wonder if there is some relation? Some type of feedback or noise cancellation issue caused by the case?

    It would seem to definitely be hardware related. Here is a vid I just took which shows the chirp occurring every time I switch the audio source from my car to the phone:

    FYI for anyone who comes across this thread - the 9.0.2 update seems to have resolved the issue completely. *knocks on wood*

    I got another nasty chirp this weekend. Definitely when dropping from T-Mobile Wifi to LTE, right in the middle of a call. I'll try the OS upgrade, see if it helps me.

    YES! I'm on T-Mobile and mine chirped very often till the point where I didn't put my ear to the phone after hitting SEND as it was so loud it hurt my ear....and maybe even the phone's earpiece! It happened less and less while I was on 9.0.1 and is completely gone now that I'm on 9.0.2

    At first, I was worried it was a bad amp and excess voltage was being sent to the earpiece. It was very loud. And I'm wondering if that was the cause for some crackling I am hearing now in my earpiece when I turn the volume up behind 75%. This also occurs if the person on the other end of the call speaks loudly or has a deep voice. The "crackling" is intermittent and is less obvious when I turn the volume below 50% So either Apple put in a weak earpiece that can't handle the increased volume or I have a defect.

    Anybody else with the earpiece "crackling" issue when you talk on the phone with the volume up beyond 75%?

    So what was the fix? I am experiencing this on iOS 10.
