Silent switch randomly turns on - iPhone 12 Pro Max

My new iPhone 12 Pro Max toggles the silent mode switch randomly to the on position. I don’t know why it’s doing that. I’ve turned off the “do not disturb” and “schedule” functions but the silent mode still toggles randomly to the on position. Could it be a software issue?

iPhone 12 Pro Max, iOS 14

My switch was being toggled by the Apple silicone case. If you have an Apple case, you can easily duplicate this by gently pushing the top left corner of the case (the one nearest the silent mode switch) toward the back of the phone. Without much effort, it will trip the switch. So, in my case, when my phone was in my pocket, it would often flip the silent mode switch. Since I returned the Apple case and replaced it with an Otterbox Symmetry MagSafe case, it no longer accidentally flips the switch. However, the my MagSafe wallet does not stay on as well as it did on the Apple case. I do not know if it's due to the strength of the magnets or the fact that the silicone case was "grippier" or something else. I saw where another poster replaced his Apple case with a Nomad case and the problem went away. Good Luck!

Which Silent Switch are you referring to? The Silent Switch is a mechanical switch located to the TOP LEFT SIDE of your iPhone. Can you clarify which switch is turning ON by itself?

You stated that DO NOT DISTURB is set to OFF and SCHEDULE is also set to OFF. That is good.


How about SILENCE UNKNOW CALLERS ? Is that set to OFF? Open Settings ➔ Phone ➔ Silence Unknown Callers : Ensure that this feature is set to OFF.

I got so frustrated missing many important calls on my iPhone only to find the top left mechanical mute switch had accidentally been activated. I tried taping over it but the tape came off relatively quickly. Out of pure frustration I used a small file to file down the protruding switch until lit was flush. I am still able to operate it with my finger nail and have had no problems since. I hope this helps others. I suspect a combination of the switch protruding a little further than necessary and having not enough resistance to movement may be the cause of the problem to an otherwise faultless product.

Hey Cathie! I have the same exact issue with my iPhone 11, the silent switch goes on off without be touching it. Don’t understand what is causing it, did you find a solution to this? Thanks, just a bit concerned about it

That is impossible. There is no solenoid in the phone that can move the switch. If it changes its position the only way that can happen is if some external force moves it. It may be the case, or, if you carry your phone in a back pocket (a very, very bad idea, BTW, the worst possible way to carry a delicate $1,000 device) it could simply be brushing against your clothing.

Read back away's. it's not the switch that is turning itself off. It's the Apple case. Push the corner of the case back and the thin plastic part on the front side of the switch will flip it off. It happens sometimes when handling it and if the case gets pushed back while the phone is in your pocket. For me it happens all the time. I cut the thin bar off and the case still stays on good and doesn't turn off the ringer any longer.

Yeah I’m finding it is accidentally getting tripped, presumably when taking out / putting in pocket or moving it. As others have said it’s strange as it’s not unlike the same switch on earlier iPhones, perhaps it protrudes a little more or has a less stiff action, but I have had several generations of iPhone and this is the only one I’ve had this problem with.


it is impossible for the switch to move by itself, it is simply a minor design flaw causing a significant annoyance, but I doubt much can be done about it for those of us that own the 12 pro. Just gonna have to get used to checking it’s not on silent!!
