iPhone X crashing
I have a iPhone X 64 GB running ios 11.2.6, I noticed an issue recently when i would save a PDF from the web and then from the PDF try to "copy to iBooks", it would open iBooks and then restart the springboard. I have tried turning my phone off then back on, closing all other apps, but each time i try to copy to iBooks it restarts/ "crashes" the phone.
iPhone X, iOS 11.2.6
