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.
Update: i spoke with attle support (italian one). They run a system diagnosis, no issues.
Then they said they made specifics checks regarding this issue and they told me it's expected behaviour, there is no hardware fault that can impact system functionality and this problem "could" be solved with next system updates.
Noticed it immediately on both our new iPhone 12 256—A bright flash on the first attempt to start up the phone followed by about 10 to 12 seconds of a black screen until the logo appears normally. At first I thought it was the way it operated. But I had to call Apple about something else and realized that this was not normal. We restore the operating system to the most recent and it didn’t go away. After almost three hours on the phone, I was told to go to the Apple store. Our phones are not even a week old yet. HELP!

Same here on a 12 Pro 128gb 14.4.1
Seems pointless exchanging the phone when an update will fix it!
Correct. To be clear, if you hold the Side button until the first Apple logo appears, and then release it, and the phone starts normally 15-30 seconds later without any further action on your part your phone is working as designed, and this is just an annoying glitch in the boot-up process. If the phone has any other symptoms they should be reported to Apple using the Get Support link at the top of this page. Any other issues are unrelated to the double-logo appearance, and should be dealt with separately.
Pressing the Side button several times won’t cause any issues, but it’s the equivalent of pressing the same floor button in an elevator several times.

What is the solution?
There is no solution, because there is no problem. It is working as designed. There is a minor cosmetic glitch currently where the Apple logo does not stay on until the phone finishes its startup process.
If you had bothered to read the thread you posted to you would have found that it is a common occurrence on all iPhone 12’s with iOS 14.4 and saved yourself a lot of trouble. And also that it is a harmless quirk.
I went to the apple store genius bar the other day and was told by the support staff this is a known issue and their proposed solution is to wait for a software update. Here’s their email for confirmation

It's not. Apple support said that to several here and they replaced their phones only to find out the replacement did the same thing. Allegedly is it fixed in 14.5. Time will tell.
FWIW, I raised an executive escalation after receiving my replacement phone, which had this same issue. Their senior engineers ran through some diagnostics and noted that they are aware of the issue. That being said, this issue may not have communicated to all 1st level support staff. At least this issue does not affect the functionality/operation of the phone.
It was fixed 4 iOS versions ago (14.5, 14.5.1, 14.5.2 and 14.6). Go to Settings/General/Software Update and update your phone.
And read the Apple Recommended post at the top of this page for some historical background.
Today Apple officially released iOS 14.5 and I confirm that the update finally fixed the flashing logo issue at startup.
Enjoy your powerful iPhones, stay safe and have a great day!
Yep!
I am pretty convinced its only with devices that ship with ios14.3.
I had a 12 pro with ios 14.2 -> no issue
I had 2 iphone 12 pro max with ios 14.3 -> both same issue.
A collegae of mine orders few days ago iphone 12 pro max with ios 14.2.1 -> no issue.
but are we really really convinced apple can fix this through an update?
I have the hard choice to make on sending my pro max back since I am still in cooldown period of my webshop...and indeed an iphone 11 or android is not an option :-)
I had the same issue too, I did replace 6 devices even tried to change capacity and color all with the same issue (12 pro max blue 128, 256, and graphite 256).
I noticed it's happening only after the first full charge (100%).
Used the last replaced one for 2 days keeping the battery less than 100% it was working fine but last night I decided to fully charge it and then the apple logo start to flash again now.
People are not reading the posts before posting there troubles... most answers are already here.
The issue looks to be part of iOS 14.3 and not in the phones hardware as iOS 14.2.x works fine, so Apple should be able to address it with software. It also does not effect the operation of the phone, only reboot which no one should be rebooting much anyways... since the release of iOS 14.4 went golden last week and is coming out this week before this issue was really noted by Apple... I do not believe the patch/fix for this issue will be in this update so we may may have to wait a bit longer for a sub-dot-release 14.4.x shortly after.
Apple senior support advisor told me directly that they will fix this issue... Apple also has a video I sent them showing this issue happening in a support case they have created on this problem.
When i called customer support last night about the single flash apple logo when starting up the phone, they said it was a software issue and it was normal as long as the phone has no performance issues, hopefully it will be cleared in a future update
I have an iPhone 12 Pro Max, which has had this issue since purchase two weeks ago. After the flash there is a delay for a few seconds and then the phone boots normally. I can live with this, and apparently from what I have been reading there is a fix coming in the next update. I am convinced this is a software issue and I will not be exchanging my phone. Aside from this minor issue, it is an excellent phone.
Yes, you are correct. No second press after the logo flash required. Just be patient, it does take approx. 10 seconds of staring at a black screen if you're the anxious type that stares at the iPhone during bootup to make sure it indeed starts up. I'll try to wean myself off this habit.
