No "trust this computer" dialog box
Since the iOS 10 update on my iPhone 5s, I'm having the opposite issue of the "trust" loop that many have, in my case, every time I want to import photos to the Photos app, it says, please tap the "trust this computer" dialog on the iPhone, but there is no dialog box. Without that, I can unlock the phone, but then I don't have the opportunity to delete the photos on import...
