iPhone 12 Pro Max New iPhone 12 Pro Max Interesting thing. It starts the phone, but flashes once the apple logo starts and then disappears

I have also the same issue, it seems that the first batch November has no problem, and the December has problems.... My officemates who purchased during the preorder and now have iOS 14.3 have no issues, but December batch has this flashes problems

There is no such thing. I had three G0ND devices with various defects. All late builds. Some other posted posted earlier saying his replacement G0ND was perfect according to him. In essence there is no good or bad serial number. It’s a myth. Same as good or bad display serials. Myth.

What do you think is the problem? I am now worry for this long term effect

I would say that if there aren’t any issues with how the phone functions, then it isn’t a big deal. My wife’s iPhone 12 Pro Max exhibits the behavior reported by the OP but has no functional issues.

My 12 Pro Max (brand new) started exhibiting this issue after restoring from backup. So far no functionality issues but I've only begun using the phone for a few days. I'll have to see after a few weeks use.

The November Batches have no issues. But some December batches experience this unusual thing. I am based in Bangkok Thailand.

How are you so sure November made phones have no issues? and how do you tell which phone is made on which month?

I’m glad I found this page. I’ve noticed this happening with my new iPhone 12 Pro Max 256 silver. BUT it only happens during hard reset and the reset doesn’t complete. I press up volume, down volume, then hold the power button. I get a bright flash for a fraction of a second, then nothing. It never finishes. I have to let go & press again. I may get another bright flash & it still doesn’t start up. After a few tries it will start up again. Have been debating sending it back. After reading comments here, I’ve decided to do so. It is serial #G0ND (g,zero,n,d)..

I want to update my post. I received a replacement phone today, exact same model. It started fine without the strange flash which was there from the first start on my previous phone. To note, serial number starts with #G6TD... on the new phone. Hope it stays good. Will update if anything changes. 😊
 
I received my 4th 12PM today. My previous one was week 51. This is week 52. Same factory for both (F2). The previous one didn't have this issue, but the new one does.

Me too, same situation. I didn’t know it was an issue and thought it was a glitch boot up but when I tried restart my phone after a TikTok bug (no videos where playing even after force closing the app) the Apple logo flashed. Then black for a second, and everything was fine. Didn’t try again since. No magesafe charger just a QI one. It’s a G0N 12 PM week 52
 
Interestingly enough, my wife just bought an iPhone 12 (not Pro), and guess what? It’s doing exactly the same thing!

She’s got an appointment tomorrow to have it looked at. The rep on the phone said they had never heard of this issue before!
 
I’m not trying to be funny and sometimes types words don’t come across as intended. But why does this made up issue matter ? I think we have other pressing issues to worry about, like raised blacks, scratched frames out of the box and green tints. I’m giving True Tone aka wanna be Nightshift a free ride here 😂👍🏼
 
I'm starting to think it's not a problem with the phone or iCloud or physical computer restore, because my phone (12 Pro Max) is working just dandy.
 
For those mentioning magsafe: This has nothing to do with that. I don’t have magsafe or any other wireless charger. The phone hadn’t even been charged before it happened. It happened with the very first setup and the first restart. It was fine during the initial boot up, but when restarting, it happened.

Exactly. I never used mag safe either. And with each reboot it was harder to get it to come back up. It would flash, then stay black. After it took 4 tries two days ago (I’d given it almost 2 wks), I called to exchange. I wasn’t going to waste more time on something that costs over $1k & obviously has a defect.
 
I'm just wondering. Are all these week 52 phones with 14.3 preinstalled? I've talked to support and mentioned this problem. He will keep me updated and I've gotten a direct support connection for the next 7 days.

Not sure what week 52 is? Mine was picked for shipping from AT&T on 01/11/2021 if that helps.
 
I am also experiencing this bs. You either have a flickering screen or a weird boot sequence. I am on iOS 13.4 RC and same thing. I think it is a software issue. I have never used wireless charging but It might be linked to bluetooth so lets see if everyone here has an Apple Watch paired to it or not?

There's many more reports on the Apple Community forums of this issue now; it's far from made up. What's not clear is how it affects functionality. For some it seems to just be on boot up, where you see the logo flash then the phone works normally. For others, it affects whether the phone switches on at all, or if it even be reset, so it's not just the logo flash in isolation.

Ok, thanks for the clarification. Appreciate it.
 
Obviously people who have phones with the logo flash and normal boot up wouldn't be on this forum in the first place, how many people here have the logo flash but boots up just fine?

Definitely seems to be an issue with any phones that shipped with iOS 14.3, looking here and at the Apple forum thread. Hopefully an easy fix will come soon. Still happens to me on 14.4 RC, but no other problems with the phone.
