I lost all the pictures during new iphone set up
Please can anyone help me? I was upgrading my iphone yesterday, i did everything as instruction said so i transferred data from old to a new phone and i had all the pics form 2021 until now transferred however, for some reason probably because of icloud my both phones connected and when i was deleting pictures on old phone, not only pics but voice memo and notes everything was disparaging on new phone as well. I didn't know that, i cleared old phone upgraded system and went to sleep. Somehow data disappeared also on new phone and icloud. I checked icloud and is empty, both phones are still connected, when i make a picture on one, it shows also in another one. Is there anyone who knows how to restore my memories?
iPhone 15, iOS 26
