When I updated yesterday I noticed a bit of a lag at first and discovered that my Photo library of about 2500 images along with 6 or so sub folders was being "restored" (actually said Restoring....". This took about 20 minutes as the count of photos increased to the final total and then the folders populated and new folders were created for Selfies and Screenshots (which means it was scanning my whole library to find these). After it finished doing its thing the phone was much more responsive. I only noticed this restore after I opened Photos. I wonder if this is happening behind the scenes on every update or whether I was just "lucky". Anyone else see this?
