Apple logo flash at startup

I updated to 14.4 and am seeing the logo flash at startup. I’ve had the phone for less than 24 hours. NOT a happy camper. Blue Pro Max 128. I tried the update because I had terrible reception, dropped calls, no signal. What a lemon.

Same issue. I had 4 replacements and the same issue everytime. 256GB Graphite and the problem was from when I took it out the box and turned it on for the first time. Returned and got a Gold 512GB with the same issue. Returned again for the same and same issue. Returned for a 3rd time and got the Graphite 512GB to find it was fine for a day and then restarted just to check and guess what?!.....

Can't be bothered returning anymore.. Will wait for Apple to respond...there better be a fix for this!!

Yes, you can; however, the recovery splash screen doesn't appear on the phone, even though the Mac recognizes that the phone is in recovery mode (once the cable is connected). And doing a recovery or an update doesn't eliminate the issue, even though it reloads the OS and the firmware.

Hi again. I went down to the service provider shop and they gave me brand new one! They could se the error when it turned on and also the burn-in on the screen, even though its hard to see. The new iPhone 12 Pro i got instead had ios 14.2.1. and didnt have the flash error when turning on the phone... It starts normally, like an iPhone should! I'm not updated it to the newest ios, before they fix it... !

Facing same issue on iPhone 12. Updated device to 14.4 but that weird startup behaviour still exist. I talked to apple support they told me that most probably this is just a software issue which will get fixed in upcoming updates. Let’s hope that apple will take this issue seriously and fix it as soon as possible.

While doing the new iOS 14.4 update (which does not fix this issue), did anyone notice the initial apple logo that come up while the phone is installing was super bright as well (which took quite a while)... but on the second installation restart the apple logo was normal. Interesting yes? Happened the exact same way for both my iPhone 12 Pro Max and my wife's. Some people have been commenting about this burning in the apple logo into there OLED screens which is very possible but I did not see that happen to my phones. I wish Apple would expedit a fix to address this soon... Apple seems OK to swap phones out all the time which does not fix the issue and I spoke to a manager at apple support about this two weeks ago and nata...

i think the screen burn from others is nothing related to the apple flash because even the flash gets bright it is just the max light it can emit. which is pur phone is capable. and its a hardware issue.but the flashing apple seems is a software issue

I too had my iPhone 12 Pro replaced and the same issue with the brief flash of the logo. 14.4 did not fix this. Called Apple and they were not aware of this issue. Informed the support rep and all they wanted to do was a reset/restore. Really poor support from Apple for such a pricey phone. I came over to Apple for quality, this is not the case with this issue/phone.

I got the exact same problem with the flashing Apple logo. I hope apple can fix it soon. I also noticed that my IPhone charges really slowly, too. Don’t know if there is a connection between these two problems

You know, I wish Apple would at least admit there is an issue. It is annoying. You pay a lot for a phone, in this case an ugly phone (its a brick), but one would expect it to at least turn on properly. Never had this issue with Samsung or HTC. Not very good Quality control.

I've been noticing this issue since I got the phone 3 weeks ago. Last week, I called Apple support about this over the phone since it's bugging me, but was told that this was normal... which is obviously isn't. You can see just from rebooting videos on YouTube that this isn't normal. I read from somewhere that this could be an indicator of a corrupted system file. I'm also not sure what's the next thing to do, though.

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.

Thank you Shawky101 for your reply. Although I read some comments of people saying that the issue appears only after the first full charge (100%), I did not speak about that in my post due to the fact that two users (MrMiyamoto and roT-) wrote that their iPhones were already experiencing the issue even before the first charge.

I get your point of view, after so many replacements it is logical that you get that impression. But if what they say is true and they are sure, then there is no direct relation between the flashing logo and the first full charge.

Please note as long as the flashing logo issue start, the feedback screen also become blank during the recovery mode and battery out of charge screen.

thats also tested in my last device and feedback screen was perfectly fine before the 1st full charge.

hopefully this will help recognizing the issue.

My iPhone 12 Pro pre-shipped with iOS 14.3. After unboxing, when I turned on the phone, I already had this flashing logo issue. I had not charged it at all. I've updated it to iOS 14.4 and the issue still exists.
