Thank Brian,

 

No, It’s when the app starts again after being closed. You get the splash page, 
the cached page for .1 to 1 second and then the first card of the app is 
displayed. It’s particularly noticeable because our fist card is the same as 
the splash screen so you get splash/cached/splash. I’m getting a lot of noise 
because the vast majority of other apps don’t exhibit this behavior.

Subject: Re: iOS cached Screen Flashes after Splash Image

 

Sounds like an OS thing. When you double tap the home, is that the screen that 
flashes? I think the OS caches the last screen for switching and throws that up 
before the splash. Apps that resume will not notice. The faster the device, the 
less likely you are to see it. At least that is my non-educated guess :)

I'm getting a very strange complaint from one user who has an older iPhone 5 
running iOS 11.2. When the app opens it briefly flashes the last screen that 
was up before the app was closed. This happens in between the splash page and 
the app's first card. The page flashed page sometimes even has an "answer" 
dialog from a previous session! I can't replicate it on any of my 3 iOS 
devices. I also noticed that Pandora and Google Maps does the same thing on my 
iPad Mini but on my iPad or iPod. The user has two other non-LC apps that are 
doing the cached flashing. All of the user's other apps except for LC apps and 
two others don't exhibit the flashing behavior. I'm wondering if the Apple 
throttle-back for older batteries is exposing: a problem with LC(and other 
apps), an iOS bug or their device need a factory reset. The last thing I want 
to do is have the user factory reset their iPhone and have the same thing 
happen. Could this be an Apple bug for testers that side load many versions of 
apps? This user has side-loaded many versions to test. Then I had download a 
store version of the app that never did it before and it's now happening but 
never did before. I find it very strange that apps that never did this are now 
acting strangely. I find very little in web searches on this subject. The few 
hits I've seen were mainly Safari a couple of years ago and a one or two non 
native Xcode "app building" platforms.

Has anyone else ever seen this?
Thanks
