Knocking sound on iPhone calls

Yes it does sound like a hammer but I never know when the hammer is gonna start banging

Been there done that don’t bother with Apple they can and did not help other than texting all checked out find with them. Total waste of time 👎

Agree with so many users here. To me it sounds like the metal string hitting the glass bowl on a ceiling fan… I have t-mobile and am iPhone 15.

Did it sound like clapping ?

Unfortunately the knocking happens off of speaker too.

Same here I only hear it with certain people and one of them don’t have a IPhone

Has anyone found a solution. I have the exact same issue suddenly with an iPhone 11 Pro Max on Mint Mobile

I just changed from cricket to Mint and I have an iPhone SE. Tonight I called my son who is also in Mint. I could clearly hear a knocking sound like knocking at the door. My son does not hear it. Why would I be hearing a knocking sound when I make a call?

Just to keep this thread alive, I have the same issue with my iphone XR also with a t-mobile plan. Context: Just moved to the US and this wasn’t happening before with my other carrier in a different country. Description: knocking on background of calls to another iphone that the other person can’t hear. The tempo of knocks is consistent and they stop after 10 to 40 seconds, and come back a after a while. It’s annoying.

As almost all of you, I have a tmobile line, its looks to me like this is a carrier issue. By the way, as Mint’s service piggy backs connection from t-mobile infrastructure frequently (thats why they are so cheap) this might be why some Mint iphone users also experience the issue.

Ps: I noticed on some other threads back in 2015, that iphone 6 and 6S users with Verizon had a similar issue. No solution seems to have been found other than switching service, maybe we should do the same.

I have a Samsung Galaxy 22 Ultra and hear the same sound. It started when I switched to TMobile from Verizon, but it's only with 1 person and not all the time, usually at night. He has an iPhone and Verizon. I don't know the specific iPhone. The sound is also different volumes. I tried screen recording our call so I could prove I wasn't going crazy and it didn't pick up any sound, just the screen. After reading all the comments here it feels good to know I'm not going crazy. It also doesn't happen when I talk to other iPhone/Verizon users. Are there any other people who have phones other than iPhones having the same issue?

Same exact thing happening with me. The timbre/quality of the knocking seemed to change, sometimes getting more intense, but always the same tempo. Girlfriend can’t hear it on her side. Seemed to only happen when she was on speaker phone, so perhaps that’s something to troubleshoot? Girlfriend has an iphone. Mine is an iphone XR. Hope more people comment so this thread can get bigger and a solution can be found!

I have same issue and was sprint switched to T-Mobile after merge I have read this tread and due to my experiences with this noise/issue it has to be T-Mobile cause when it happens to me it doesn’t matter what carrier what type of phone or even if it’s a landline rather if I’m on speaker or if the other caller is on speaker I’m the only one hearing it, it may not be every call or all the time but I do experience it enough to realize T-Mobile has a problem with that and after reading everybody’s comments yes it is T-Mobile. Thank you for this tread so I too know I’m not crazy!

Im so happy this is here! I was talking to someone and they said they hear constant knocks on wood when I got silent. I couldn’t hear it through my end!!! So scary!!! Y’all gotta figure the reason and how to stop that asap!!!! Could be someone tryna spyyyyyyyyyy!!!!!!
