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.
Correct. First Apple logo flash then pause second Apple logo then starts normally.
I have no other issues as yet and have tested every app and control.
There are no reports of any other issues with phones that "flash."
We have many, many reports of just the opposite - once the phone boots it acts completely normally.
The flash is merely an artifact, don't replace your iPhone until after iOS 14.5 has been released.
Just updated to 14.5 and the flash logo is gone.
Hi, Yes already update to 14.5 and there u go its fixed. Thank you.
As others have said, the update to 14.5 fixed the flashing apple logo.
It’s a miracle! It’s gone with 14.5!
The flashing logo was fixed I jus updated my 12 pro max !❤️🔥

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.
Interesting ... I had iOS version 14.5 and still had the issue. Regardless 14.6 fixed it for me ... I might not have been holding the device correctly when I upgraded to 14.5 back in the day. :-/
I think Apple will address this issue in an update/patch since it seems like people are saying its issue is part of iOS14.3 and not the original version release... but it probably will not make it into iOS 14.4 as the master build has already been released to the developers and this update is slated to come out next week (we can always hope though)... But it really does not affect the phones operation or even the overall boot time to a normal either, just a weird startup operation. And what other choice do you have... an old iPhone 11 or go Samsung... afraid not! I'm going to hang on and hope for the best hopefully with 14.4
Well the senior engineer just called back. And at the moment they just dont know what is causing this issue. And they dont know yet if this is a hardware or software issue. So the choice they gave me is: return it to my webshop (since I am still in cooldown period of my webshop) or wait till they can fix it with an update.
I had the exact same issue when I restored my iPhone 12 pro. The phone got stuck and apple logo kept flashing bright at startup and nothing else would work until I had to force restart and restore it again.
Even though phone worked fine after that but on every restart, apple logo briefly flashed at full brightness and few seconds later normal apple logo would appear and phone would start normally.
I did exchange my phone with a new one and never tried to restore data thereafter. Wonder if apple is considering an update to fix this issue? Seems like a software glitch.
What I noticed after 6 replacement devices that the issue start only after 1st full charge.
device out of the box is working fine even after activation and moving the data .
working normally if partially charged , i kept my last replaced device for 3 days working normally with partially charged battery and when I decided to fully charge it to confirm if the issue will happen again or not. Guest what apple logo start to flash again. So i send it back to replace it.
it is a software issue and according to them apple will fix it in coming updates. what country you're from? theres a chance that you will end up with the same issue even a new device as long it is belong to january batch with 14.3 ios
