I have a web app saved to homescreen in iOS7.
While its open and running, if i double tap the "home" button on the phone, the minimized display correctly shows a screen capture of the apps current state.
However when switching to another app and then double tap "home" button to reveal the minimized app switcher, a blank, white screen is displayed instead.
In other words, if a user has switched from my "homescreen" web app to another app and then attempts to switch back via the app switcher, a blank white screen is displayed as the minimized view.
Is there any known way to fix this? Is there a way to tell iOS7 to keep the first screen capture? I have searched everywhere and cannot find a solution.
As per this link, this is a limitation of ios 7 wherein the right screenshot is seen only if it is the currently active app.
