My daughter updated to the latest iOS yesterday. After that, she deleted an app, and her phone glitched and has been stuck on a white screen with the black apple logo, which occasionally flickers. Chatted with apple support for almost 3 hours yesterday (updating, restoring, etc.) with no luck. Can't get a Genius appointment for a week or more. Was wondering if anyone has had a similar issue, and if so, what the fix was?
