iPad Mini 5 blank on start up
iPad Mini 5 64GB Wi-Fi + Cellular, purchased in April 2021 and has latest iOS 16.2, kept in a Fintie folding folio style case. I use Wi-Fi only and it's kept in airplane mode when not in use.
Twice in the past two weeks, when I've opened the case, the screen has remained black, and continues to remain so after pressing the Home button. After 30-45 seconds or so of waiting and pressing the button, I've closed the case and then reopened a minute to a few minutes later and it shows the first screen as normal. When this happened yesterday, it showed 100% charged, and I think it was similar the other time as well. Any ideas what might be going on? Before the Mini 5, I had a Mini 2 for several years and never came across this.
