New iPhone 12 Pro. At startup the Apple logo flashes super bright for a brief second then the screen goes dark for about 10 seconds before the Apple Logo re appears at normal brightness to finish the startup. I’ve had iPhones for years and never had the logo turn on and then off during startup. Is that Normal for the 12?
iPhone 12 Pro, iOS 14
After more than two weeks, I think that it is time to sum up the situation: the "flashing Apple logo" issue described by Blue-per does not occur when we unbox and boot the iPhone 12 (mini)/12 Pro (Max) for the first time, it occurs when the iPhone is already set up.
In most cases the phone performs normally after it boots up. Some users found hardware problems when using their new iPhone (phone needing to be connected to power in order to boot up, screen burn-in, battery charges very slowly, camera not taking HDR photos, etc.).
In my opinion those problems are not related with the flashing logo at startup, because they are very different from each other and they are isolated cases. They are just coincidences.
That does not mean that the flashing logo is not an issue: there are iPhone 12/12 Pro which boots with the (classic) steady Apple logo and some iPhone 12/12 Pro that do not, so it is obviously not a normal thing. It is not a "new feature" or "expected behavior".
After reading other answers on the forum, we can deduce that the issue does not occur on iPhone 12/12 Pro that were shipped with iOS 14.1 or with iOS 14.2 pre-installed, it (mainly) occurs on iPhone 12/12 Pro shipped in January with iOS 14.3 pre-installed. As a matter of fact a lot of people returned the device during the last weeks and got a new one with the same problem.
Now, we suppose (and hope) that the issue is part of iOS 14.3 and not in the hardware of the phone. In this case Apple should be able to fix it with an update, maybe already with a sub-dot-release (iOS 14.4.X) or later with iOS 14.5. There are some comments in favor of that supposition too, where people noticed that issue after updating from iOS 14.2 to iOS 14.3.
On the other hand, it is strange that (most) iPhones who updated the operating system from 14.2 to 14.3 did not experience the issue. And it is even stranger that I read a reply from a user who encountered the problem already on iOS 14.2. Those facts contradict our supposition above, and maybe the flashing logo has nothing to do with iOS 14.3.
I am sure a lot of people have this problem too; they do not notice it, because nowadays we do not shutdown and restart our phones very often. And even if they do that, they (probably) don't keep looking at the boot screen for issues.
It is very hard for us to guess if it is a software or a hardware problem. Only Apple can give us an official answer, and in order to solve the problem as soon as possible I ask you to continue upvoting this and other similar posts (clicking on "I have this question too"), commenting if you have some news from Apple and reporting the case to the Apple Support.
Hi all,
Finally everything seems to be resolved with 14.5. Upgraded and the phone loads just fine 👍
updating to ios14.5 solved my logo flash problem also
Facing that issue on my 12 pro max for last 2,3 months
got a latest update 14.5.
issue resolved
thankyou apple for your support 👍
Have you updated to iOS 14.5.1? That fixes the issue.
After updating to 14.5.1 today, it seems that the issue was fixed!
I had the same problem. But since I updated to the latest version of iOS, everything’s fixed.

Same problem here, I have the iPhone 12 Pro (iOS 14.3)
And like all the other users reporting the insignificant graphic glitch, it will be fixed by updating to iOS 14.5.
There seem to be more reports of this issue over the past few days; as of now, there's no official response from Apple yet, but it's certainly not normal.
For the most part it seems the phone can function normally after it boots up, although in my case it eventually led to the phone needing to be connected to power before it would boot up. I'm waiting to see what Apple says over the next few days.
The senior advisor indicates that this is something that software cannot be solved moderately and that it requires a repair or a replacement.
In addition, he also indicates that if there are no further problems with the iPhone, this is not necessarily something to worry about or that other problems may arise due to this phenomenon.
So now you have the choice to continue with a repair or replacement, or to accept it as there are no further problems with the iPhone besides glitching in the reboot.
I just hung up with a Support specialist via chat who had me run a diagnostic on my phone, and finding nothing she could fix, had me visit with a sales specialist. That guy told me that because I traded in an old phone, I had to make an appointment to go to a store to exchange. What a hassle. I've only got a few days left, too as it seems I have 14 days upon receipt of the phone to make an exchange.
I am very happy that I have found this threat.
I bought an iPhone 12 Pro 512GB (white) with serial F2xxxxxxxxxx last week at German Amazon.
On first start everything worked OK. I turned it off to to do restore later on. At the second power on I have seen this strange behaviour. I restarted the iPhone with a "reset" - same strange behaviour.
I did a "recover" and a "DFU recover" with iOS 14.3 and the issues persists.
Today I called the German Apple Support. The support agent searched the knowledge database for this "logo flash issue" -> no hit.
The agent did a remote diagnostic and the diagnostic indicated -> "no issue found"
Therefore that "no issue were found" the agent told me, that a swap of the device isn't possible - I can just send the device in for repair. :-(
The agent recommended that I return the iPhone to Amazon for a refund and buy another one some weeks later...
Currently Amazon is sold-out therefore I have to wait anyway.
I hope that Apple will find the root cause soon!
No, they removed it because someone who was level 2 or higher reported it.
As has been previously posted many times, this is not the place to look for a “formal” answer from Apple for anything. To communicate with Apple use the Contact Support link at the top of this page. You still won’t get a “formal” answer unless one has been proposed by engineering and approved by Marketing and Apple’s legal department, but it will help Apple identify the extent of the problem and prioritize fixing it.
With any software product as complex as iOS at any point in time there are thousands of bugs. It is impossible to fix all of them, and any time you fix one there is a finite probability of causing another one. So the known bugs are sorted into a priority list, with the most critical ones (security vulnerabilities) at the top. Ones that cause the phone to crash are near the top, along with bugs that interfere with normal operation, followed by those that have a workaround. Bugs that are purely cosmetic and don’t affect operation or use of the phone, such as an Apple logo that flashes a couple of times when doing a cold start are pretty near the bottom. And as most people rarely (or never) actually turn off their phone this one affects amazingly few people.
Your issue sounds a little different; is it blinking just once, or multiple times? Also, the issue discussed so far in this thread seems to only affect iPhones delivered since the beginning of the year with iOS 14.3 pre-installed.
In any case, you can try restoring your phone to re-install iOS 14.4, in your case it might resolve the issue.
Because the “flashing logo” is a purely cosmetic issue that has nothing to do with the phone’s operation, as can be determined by the many reports from people whose phones do only this, coupled with the fact that there is no linkage between it and the myriad other issues people want to connect it to.
I had the same issue. Exchanged the phones for more than 3 times in the Apple store, but all the new ones I received had the same issue.
Finally returned the phone and received full refund.
Found a small mobile store in my neighborhood and requested him to find a iPhone 12 Pro Max with a production date of November 2020 or earlier.
He made many calls to his suppliers from various part of the country and found a phone which was assembled in November 2020.
Now the phone I bought doesn’t have the issue.
Peace of mind at last.
Thanks to the small mobile shop friend.
All started in October 2020 (with extended return date due to year end festival offer) and ended well in February 2021. But lost lot of branded screen protectors and petrol for the trips.
