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
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.

If it's happened to be that (hardware) problem, what's the solution for us (general users)?????
If purchased from Apple or an authorized retailer you have a one year warranty, longer if you have AppleCare+.
We don't have any other issues happening so not a big deal. Perhaps other issues are not due to this. I also found with both our phones we hold the button down, the flash happens about 6 or so secs in, then release the button, don't keep pressing it, then about another 8 to 10 secs later our phones boot up. I too called Apple, got a pleasant person that honestly said they did not have any information but her family also had phones that did the same thing and she put in the report so hopefully if it is not normal will be addressed with the next update. Cheers!

Same issue here. Already replaced the phone four times😓 still got it
And if you replace it 10 times you will still see this minor cosmetic issue until Apple releases a software update that fixes 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.

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.

No, you DON’T need to press the power ON button several times. Release the button when the logo first flashes, and WAIT. The phone will start whether you press the power button several times or not. It will take 15-30 seconds to start.
The “issue” is not an issue. It is a minor cosmetic bug. To turn on the phone, press the Side button until the logo appears (or “flashes”) then let go. Wait 15-30 seconds for the phone to finish booting.
If you have a battery life problem that is totally unrelated. Start a new thread for advice on how to fix that issue. No one will see it who can help in this thread.
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.
