iPhone 12 Pro Lock Sound Issue

the same here. 12 Pro. But i've discovered one thing. if you do hard reset (volume up, volume down and hold power button until you see apple logo) that fix the problem.

The problem happened everytime i connect magsafe charger or the silicon case magsafe in iPhone. If i use thunderbird cable no problem. if i reboot the iPhone no problem. only when attach the magsafe (something) the problem come back.

so maybe it's the sound of magsafe create a bug.

I’ve had this same issue, i didn’t really notice it much at first i thought that the sound was changed. It was only when it changed back temporarily that I noticed it. I’d say it’s definitely some kind of software audio bug, as when I removed the magsafe case the lock sound returned to normal. Put the case back on and it went back to being weird.

So, as instructed by support I did a reset and restore, however as I am pretty sure this is some sort of bug I opted to do a restore using Apple configurator on my Mac instead of the erase all content and settings through iPhone as using configurator would download a fresh copy of iOS 14.1 and so far (almost 24hrs later) the problem hasn’t returned!

The soft reset did work for me but only for a few times of locking.

My guess is that some, if not all iPhone 12 Pro’s have potentially shipped with a rogue/corrupt version of 14.1.

Out of interest what types of 12 pro do you all have and which country did you purchase from, mine is the Pacific Blue 128GB from the UK, just wondering if it only affects certain models etc

This doesn't fix it. I'm now on 14.3 and the issue persists. It does seem to be MagSafe that triggers the strange lock sound. One work around that I have discovered is that if I flip my silent switch before I apply MagSafe charging, when I remove the MagSafe, and flip the silent switch back (silent off) the lock sound still sounds normal. Kind of an annoying way to fix it, but it seems to work.

Issue is not gone in 14.3... It's very strange but if you reboot the phone, the issue seems to go away. If you attach a magsafe device, the issue is back. Rebooting the phone fixes the issue... Until you attach a magsafe device again.

I'm using the magsafe case.

It appears to be fixed in iOS 14.4 that will be released soon (now in release candidate stage)

@sebrem and @nixle32: iOS 14.4 fixed it for me, too.

iOS 14.4 has fixed the issue for me. I have not had the problem since upgrading to it once it became available.

eh... the problem for me it's that... everytime you attach magsafe (charger or case) the bad lock sound come back...

with soft reset fix the problem until next time you put in the charger. i've tried to put a normal charger cable (lightning) and no problem.

This has been driving me nuts. At least I know why it’s happening. I wish Apple would fix it.

For what it’s worth, I’ve confirmed it’s related to MagSafe. I removed my MagSafe case and powered the phone off and back on. The lock sound was normal when I tested about 5 times. Put my Apple Leather MagSafe case back on and the lock sound started making a “clack” noise again. This is with iOS 12.4.1.

This is what I did and so far it's worked:

1. Remove the magsafe case.
2. Soft reset phone to rectify the "clack" lock sound.
3. Turn off the phone by holding down side button and volume button together.
4. Replace magsafe case whilst phone is turned off.
5. Turn phone back on.

The lock sound should stay normal and not return to the short "clack" sound, as long as you don't take the case off and put it back on whilst your phone is turned on.

Noticed this issue as soon as I got my iPhone 12, keyboard & lock sounds volume variation and the magsafe animation that make the lock sound go crazy (loud click). Plug in a magsafe accessory like the charger without power that will not trigger the magsafe animation and your lock sound will stay normal so it's related to the software. As for the system volume variation I get the same issue with the iPad Air 4. Apple dev team should read their own boards to fix things...

The newest update 14.3 does not fix this issue....at least not for me. Currently, there’s only the temporary fix of restarting the phone.

It seems to be entirely caused by the MagSafe charger and/or the MagSafe case. Could something else be causing this too? Who knows. Many people are saying this bug causes changes to the screen lock noise and the keyboard typing noise.

I have the iPhone 12 Pro Max. I don’t use the MagSafe case. I do, however, use the MagSafe charger. Every single time, the moment I take my phone off the MagSafe charger, the lock noise ends up changing to a loud one click noise. If I restart my phone, the lock noise goes right back to normal. I too have noticed that if I’m watching a YouTube video, playing a video game, or listening to iTunes, and then lock my screen while doing these activities, the lock screen noise goes back to normal. However, if I unlock my phone, close whatever app I was using, then the lock noise goes right back to being loud. Only restarting the phone helps.....until I use the MagSafe charger again.

I’ve contacted Apple for help. They have no idea what I’m talking about. Gives me little confidence they’ll fix it anytime soon....

I solved the problem. This is an issue with Magsafe. Make an appointment and go to the Genius Bar Request a Magsafe replacement and you will realize that with the new magsafe all the problems are solved

IOS 14.4 public beta 2 seems to have solved the problem for me (12 Mini). Screen lock sounds stay normal after connection with magsafe leather cover or using magsade charger.
