iPhone 12 Pro Max Bluetooth Issues

Try using your Find the phone function and from there is the ability to erase the content. That should do it. I hope.

Try go to settings Bluetooth and disconnect and for forget device and then pair them anew.

Yes, I did....they ran test diagnostics on my phone remotely and discovered it had a hardware fault. They tested it again when I returned it to them and have sent out a replacement...

Hi,

reset all network settings, it works for sure

do you have your 12 pro’s since launch?

I think it’s a hardware issue with the first batch. My second iPhone 12 pro have none of this bluetooth issues, but my launch iPhone 12 pro will have

I’m having the same issues but with almost all my devices.. I transferred everything from my old iPhone X to this 12 pro max and after setting up this new phone tried connecting to my work vehicle with Bluetooth and nothing. Sound system nothing. It doesn’t recognize any devices but it recognized my tv.. not sure what’s going on with Apple but this is kind of rediculous

I cannot connect my 12 Pro Max to my cars Bluetooth (hands free calling only). It’s been driving me crazy.

I also have an issue with the echo auto. The phone keeps thinking it’s a pair of headphones instead of a Bluetooth speaker and keeps turning down the volume after a certain period of time.

It’s so annoying and I’ve been back and forth with Apple support and their engineers and they basically told me to contact Amazon—even though it works fine on my XS Max and 6s+.

This is so annoying and needs to be addressed immediately. When I’m driving this is a safety hazard.

I'm having the similar issue. I upgraded from the iPhone X to the iPhone 12 Pro Max, they are both running iOS 14.2.1. I'm having issues mostly with calls and slight issues with streaming audio. When I'm on a call, I'm having a static noise in both hears and people claim to have a hard time hearing me. When I'm stream audio, the i get a loud chirp when switch between apps or when streaming stops.With both Phone call and audio streaming, the bluetooth will disconnect randomly and won't allow me to reconnect. It's almost like they are out of range. None of the issues occur when I'm using my iPhone X.

I've been reading everyone else's posts, and seems like there is a huge APPLE problem with the connectivity of the iPhone 12 (I have an iPhone 12 Pro Max). I work with other people with older iPhones, and their phones connect with no problems to the same devices that my new phone won't connect to.... it's so frustrating. I've reset the network settings, but that did not solve the problem. Has anyone found a solution?

All the paired Bluetooth settings are kept on the cloud. So as long as the old iPhone is still registered to the apple account the paired Bluetooth settings remained with the old iPhone and the devices can’t show or be paired with the new iPhone with the same name. I finally erased my old iPhone and removed from the apple account. Now all 7 separate Bluetooth devices are paired with the new iPhone. The problem with Wi-Fi calling turn on notices all stop also. Apple’s engineers should have figured out the potential problem and address it in Help. Job would agree I think.

I’m having the same issue majority of devices on Bluetooth connect but some don’t. Strange as old XR connected perfectly, it’s only the 12 that doesn’t.

one of the most helpful answers I found was to go to settings, general and reset the network setting. Didn’t work for me but has worked for others so worth a try.

guess I’m just going to have to wait until a new IOS issue solves the problem.

I also went into my older Lexus Bluetooth car phone to delete all previous pairings to two ex iPhones and then pair to the new Pro Max. It’s working. The only time I had problem with intermittent connection was a device low battery.

When I transfer from iPhone6s plus to Pro max got same issue with Sony WH-CH700H and another MDR-ZX770BT, just in Bluetooth device list their never show-up and i-watch can not pair to then either after upgrade the new iOS

This is happening to mine as well. It is so frustrating and I tested my phones Bluetooth on two different devices which helped me determine that it was in fact my new phone and not the other devices. I was first experiencing the constant Bluetooth connection loss on my wireless beats and then later on my cars Bluetooth. Apple needs to fix this because this is beyond frustrating

On followup---it seems like a bluetooth audio sync problem when the iphone 12 (bluetooth turned on) syncs to an existing device that is powering up. I can get my Mercedes audio working if I toggle the bluetooth on my phone off and on for about 5 seconds once the car system is fully powered up and it will work. BUT...if I toggle on and off the car system, it still doesn't work.

To be clear when I have this problem---it looks like it is playing and all the information about the song is on the car system showing it is playing (album, song length, playing time) from the iphone...but there is no sound. Most if not all the time --the telephone audio works---so it is seems to be a problem with the Audio playback stack and not the phone audio stack.
