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.
regardless the issue is software or hardware, no official feedback from Apple, no support from apple customer services, no responses from feedback communication, we are just able to write here which is not helping us. I already escalated the issue ministry of commerce in Saudi Arabia for Arab Computers as they are not able to fix the issue in warranty time frame passed and no response from them as well. They push me to take the faulty iphone without fixation or replacement or refund.
so we are stucked and forcing by Apple to wait with new sw upgrades which we dont know this issue will be fixed and no timeplan ot announcement even for it.
If you get the blink, it’s booting, you just need to wait.
You can press the button a second time if you like, but it isn’t doing anything except making you feel like you’re doing something other than waiting.

You need to deal with a bug in the forum software:
Once it remains the white "Follow" after you reload the page, you're done. You will have to repeat the process for roughly as many times as you have posted to the thread.

Thank You Lawrence! I’ve tried just that several times but have not been successful. I so appreciate your reply! I’ll keep repeating it until it works!!
Yes, it can be frustrating but it will eventually work.
I have the same issue on my iPhone 12 Pro. The apple logo flashes at start up then followed by dark screen. I need to press the power ON button several times before the phone starts. The Software update is IOS 14.4. I hope Apple resove this issue. Thank you.
How did you like how you are assuming it is not an “issue” this cosmetic bug could be causing voltage spikes to the screen And or other parts from what it looks like. Just say cosmetic bug without testing internal voltages. It’s like seeing a car that won’t start because of a dead battery is because of a blown engine without any true diagnostics. luckily Me and my team are taking apart an iPhone with this issue. To see if there any voltage spikes across-the-board.
Because I have information that you don’t, but I’m not permitted by NDA to say how I know. Other users in this thread also know and did post their source, but their posts were removed because they violated their NDAs.
This happened to me as well. First iPhone 12 bought in March had this issue immediately when activated at home. Returned it to store and second iPhone 12 started to have blinking Apple logo a week later. Hoping this doesn’t become a more significant issue later.
I agree, unfortunately too many times Apple is justified, but after spending 1289 € (in Italy) I am absolutely not satisfied, this is a pretty serious problem, I did not return my iPhone just because I had already sold my old one 11, to avoid problems I do not turn off the iPhone but activate the "airplane mode".
Hello! I have the same problem with my new device 12 Pro Max IOS 14.4.1
I realized strange behavior during my phone turning on Logo appear twice.
I just left a report and hope that tnis problem will be fixed in new updates(
We must also have confidence to Mr.Lawrence Finch and Dogcow-Moof because they have a lot of experience and want to help us to all technical problems of the device( iphone 12, pro-pro max ) and reassure us.
Perhaps they should release that to the rest of us because some of us are not happy with "an annoying cosmetic glitch" on our 1500 dollar iPhones. Some people can't return them or want to be hassled with a return.
Brand new iPhone 12 pro max (bought March 15). After two days I experienced my first big crash. Actually it is my first iphone crash ever. The Camera app froze, and after closing it i would not load again, and neither the Settings menu. I tried a force restart and after some time I got the dreaded "Flashing Apple Logo". Out of curiosity I took a look at the Analytics log and noticed many crash logs named "Stacks" and "Jetsam", just after a few days owning it. To compare, I took a look at my late iphone 11 logs and it shows a grand total of 0 crash logs of the like on the 12PM.
Besides this crash and those many failure logs, the phone seems to perform fine. Battery is ok but not much better than the older iphone 11 though...
My iPhone 12 apple icon flashes upon star up .I may have to press the button twice maybe three times for it to startup .
This is my second device in a ten day period . If apple can not fix the issue then maybe we should try the new samsung phones or apple should compensate all iPhone 12 owners .
I am and have never had my 12 Pro Max fail to start when I pressed the button and released it upon the first flash of any kind of light from the display.
It takes a while, so any subsequent presses are no more than when people feel the need to press the already illuminated call button while waiting for an elevator.
