While loading a question the app froze. A force-quit and restart lead to a blank blue screen. Using the Return to Feed setting had no effect. Using the task switcher froze the whole device; only the power button was responsive. Rebooting the phone had no effect. Setting Return to Feed after a reboot finally got everything back to normal.

iPhone 5S, iOS 9.2, app v1.4.1

  • Sounds like a device issue, you sure all other apps worked fine? Dec 15, 2015 at 21:47
  • No problems with any other apps. The SE app almost did it again earlier when returning to the feed, but was able to recover without rebooting the phone.

  • I definitely can't take responsibility for locking up the whole OS. I can't think of anything specific that would cause the app to freeze on question load but if the feed was loading simultaneously, there's a bug with the feed that could cause the app to freeze. The fix will be in 1.4.3 in January. Dec 16, 2015 at 17:03
  • If it deadlocks or burns some resource on an EnteredForeground notification or app delegate that might give the OS some trouble keeping up. Was on a slow and patchy network at the time, so it may all be that feed freeze.

This should be fixed with yesterday's app store release. (

Please let me know if it resurfaces.
