Undeleteable photos on iPhone
I have an iPhone 14 iOS 16.1.1. I have images and video in my Photos app that have been brought along through all the device and iOS updates over the years. All of these Photos images and videos have been backed up on my mac, and from there backed up again in multiple ways on multiple platforms. The iCloud Photos option and My Photo Stream are both turned off, and they always have been turned off - I have never used them.
So here is the problem. I want to permanently remove all the photos and videos from my iPhone. But I have a LOT of old images and videos that Photos refuses to delete (I select them, and either no trash can or grayed-out trash can). They are stuck in my iPhone's Photos library, and I want them gone.
My question: Is there a way to reset the Photos library on my iPhone? Failing that, how do I get rid of these things without resetting the whole phone?
