Resetting one iPhone of two with the same content
Hi guys. I bought a new iPhone 12 and when I switched it on, it automatically transferred all the data from my old iPhone 8. Then i gave the 8 to my son as it was and later noticed that now we share photo library and if we delete photos on one phone it disappears from the other. Now I want to reset iPhone 8 to factory settings so my son has a new empty phone, but afraid to do so because I fear it can delete all my carena roll, on iPhone 12, is it possible?
iPhone 12 mini, iOS 14
