iPhone 12 Pro: Apple logo flashes not steady when doing a restart???

The phone operates properly once it boots, this is just an insignificant cosmetic issue when the phone is turned on.

If you feel differently, please tell us what functionality isn’t working when you login to your phone.

Just got off the phone with Apple and the case and diagnostic logs have been received by the senior engineers. I made them aware that this is a worldwide issue and have given them the links to the assorted threads regarding this issue here on Apple communities as well as on Mac Rumors. I have a callback from them scheduled for Friday. They need a few days to research the issues myself and others have noted here. I will report back with an update once I speak to them on Friday and see what they have come up with to that point. Once an issue goes from senior support up to the senior engineers it can take awhile as they do dig deeply, often requiring different logs than what were initially sent so now it’s just a wait and see situation. Have a great day y’all!

There are people who have other problems, but most likely they would have had those problems regardless of whether the logo flashed or not. Most of the people who responded in another, very long thread said that if the released the side button when the logo flashed that their phones started and worked normally. Some users kept pressing the side button repeatedly, which could cause issues, but even most of them said their phones started and worked normally.

You seem very careful and conscientious in your phone’s management.

That’s the same problem I had my phone. But my phone, but my phone won’t strart after the logo Apple logo flashing. So I let it go I let my fingers go at list a minute and do that for like 3,4 times and then the phone start. I went to apple store 2 times. Fist time , they fixed. They change the hardware something in the iPhone. And the second time do you get a chance restart The Second time the guy work there just restore the iOS. Tell me to go home away from you come up and update maybe fix that problem??? I’m Sure the guyI know the new update will fix the problem. I am be told that the first time they saw this happened. Now I know that’s a lot happen for Apple iPhone 12pro. My point is Pay for the phone more then thousand dollars. What I get broken iPhone. So not Exactly broken but iPhone not run right APPLE???

Yes, my iphone 12 pro max is now on 14.4.1 and it still has the flashing logo upon startup. My problem is that I'm also experiencing other quirky and not-so-subtle glitches, such as not being able to disconnect from a phone call. I literally have a green phone button & when you hit the button, nothing happens. I wonder if these kinds of issues are all related. Does anyone else have multiple problems? In the first few days of having the phone, everyone I called had a crackling connection & it turned out to be a faulty sim card. Apparently, that happens a lot.

Al Q,

Thanks for all the details you've provided. Sounds like things are working the way you'd expect when performing an unencrypted backup to your Mac, but not when encryption is enabled. We're also happy to hear you're still getting your encrypted backups manually to your Mac or when backing up to iCloud.

To further determine whether this is expected behavior or not though regarding automatic encrypted backups upon connection your Mac, it'd be best to reach out to Apple Support. They can be contacted using this link: Get Support

Have a great day!

So right now we should wait for future iOS update and hoping that apple will solve this kind of problem? Apple please do something especially for iPhone 12 pro users like us. Usually can we get a replace with a new one if we only use this phone about less than 1 month?

Interesting and reasonable observation. Any idea how / if we can raise this issue to get Apple's attention? Unless they are aware and acknowledge this to be an issue, it is not going to be looked at. And while it is not posing a problem at the moment once the device is up and running, I am concerned there will be other implication down the road. Or am I overly paranoid?

Both my wife and I have logged this issue with Apple Support under separate cases but both reps do not seem to be aware of many reported instances.

I have the same problem. I purchase iPhone 12 Pro Max last December, does not have the problem. I just purchased iPhone 12 Pro, it has this logo problem. I already exchanged it one time, still has this problem. I am thinking of returning to phone for a refund, I still have 14 days to think about it.

I submitted a report as well based on the link provided above by @Alancito. Hope Apple will address this soon... whether it'd be over a software patch or a direct replacement. I assume for a patch, it'll need to be done by a technician at the Apple store rather than a regular o/s update.

Out of curiosity, do you know the serial numbers of the problematic iPhones? Just the first two or three digits will help narrow down where these were produced, which could give a clue of where the error originated. All three iPhones that I returned started with F17.

Ok, so perhaps you can explain why the iPhone 12 (Pro, Pro Max, Mini or just 12) that were delivered prior to January don't show this on boot up? There is a pattern that's worth investigating; whether Apple says it's a non-issue in due course remains to be seen.

And I respectfully disagree that the related issues are "usually due to configuration issues on the phone itself"; I've seen them occur phones that have been completely refreshed, set up as new, with zero data ported from another device.
