Xamarin - White screen on ComposeEmail
If I open an external app and return to the first app, I will have a white screen. No lifecycle events are triggered.
When I push the back button I will be brought to the login screen. App doesn't fully crash as the debugger stays attached. But no errors are shown

The screen in which the message comes on the top side which display as - app is actively using your location.
Main issue is what I have faced when this come when my app is in the background, and I open any other app, what i see is that the UI moves to bottom side.
This issue comes only in ios 11.2.1.
Working with ionic app for IOS, I am facing one issue is that, when the app is open and then I click the home button of ios device. So then app is in background but after few seconds (may be after ~30 sec). I am trying to open the app from task manager that time on ios app shows me white screen.
Please let me know how I can avoid to display such white screen in ionic.
This bug can be reproduced using the soundcloud app.
download the soundcloud app onto an ios8 device and launch the app
minimize the app by pressing the home button and launch safari
google search "soundcloud hardwell"
click on a search result that will send you to soundcloud.com
at the top of the page should be a button "Listen on SoundCloud iOS", click it
as safari transitions to the soundcloud app there will be a few seconds where the soundcloud splash screen is not visible and will just appear as a black screen
currently I am experiencing a similar problem with my app. The app currently uses image assets for splash screens and i dont not experience the above UI bug. However in attempts to support iPad pro ive removed the image assests and am instead using a splash screen .xib file. Using the .xib splash screen file causes the black screen to appear only on iOS8. Any ideas what the problem is and how to fix it is?
Edit:
The twitter app also suffers from the bug mentioned above. This appears to be a bug in ios8?
My iOS app simply shuts down when I open notification center while the app is visible and in focus. Same thing happens if I double click the home button to show the recently used apps list.
This would seem to be an application lifecycle issue, but no errors are reported in Xcode.
How should I go about debugging this problem?
The app that I'm working on is automatically showing the splash screen only when it goes into background to make a call.
The other functions of going out of the app and becoming active again does not "activate" the splash screen. For example, going out of the app into an external website, phone map or another application and coming back into the app will show user the previous state and does not show the splash screen.
Is this something that can be controlled by the app side or is this an iOS feature that apple automatically handles when a phone call is made?
I have managed the leaks on the app side and all is good now so it can't be anything to do with memory management on the app side. Is there anything else that can be done indirectly so that the splash screen will not show?
The launch image is not a "splash screen". The launch image is used to prevent show a black screen while the app is loaded, and you should use it with an in-app screen which gives the feeling of a quick launch. If you don't show the launch image, you will get a black screen.
Workaround
So, as workaround, my suggestion is that you take an static snapshot of your App, something generic (like the background and toolbars) and use it as launch images. This will give the appearance that the app start immediately, without "splash image". This is what Apple apps do, you can see this in apps like Stocks or Settings.
You see?. The left screen is how your launch image should look.
