iphone 12 pro quick flashes apple logo when starting up.

My iphone 12 pro quickly flashes the apple logo when starting it up, goes dark for like 5 seconds and then the apple logo reappears before turning on. Is this normal?

There is one question to ask yourself. Do you end up with a fully working iPhone? If the phone works at the end of startup there is probably nothing to worry about regardless of what the screen does during start-up.


If the startup process doesn't end with a fully working iPhone you need to contact Apple Support and use the support entitlement which comes with every new iPhone.

I have 2 brand new iPhone 12 Pros in the house which are having the same issue. Apple store technician has wiped and reinstalled iOS 14.3 on one of them but did not fix the problem. At that point, suggestion was to wait for an upcoming software update but I am not holding my breath (I have also tried installing 14.4 beta 2). She confirmed diagnostics revealed no hardware issue so likely software related.
