iOS cached Screen Flashes after Splash Image

It's interesting that the user never had this problem until last week even
on apps that have not changed. I wonder if the Apple speed throttling has
anything to do with it. The user loaded some app that shows if throttling is
in effect and his speed is now reduced by .1 mhz. I wonder if this became a
problem on older devices since Apple introduced as "App Thinning/Slicing."

I don't have a clear answer for this, but just an observation: iPhone
5 was the last of the Apple 32bit hardware devices. That makes me think this
is an OS issue more than an LC issue.
