All photos from last 3 months are gone due to apple backingup on my old phone.
I was using my iphone x for 3 years and a couple months ago i switched to an iphone 15 and transferred all my data to it but kept the iphone x just incase. 2 days ago i wanted to sell my iphone 15 so i backed everything up and resetted it. Since then ive been using my iphone x as normal again but i saw that none of my photos were synced and since the seller never came to pickup the iphone 15 i transferred all my data from the iphone x to the iphone 15 again and all my pictures from since i got my iphone 15 are gone what do i do. im scared that while using my iPhone x it backed up again and overwritten all my data causing me to lose all my pictures. i disabled backups on both phones for now but are all my pictures and whatsapp chats since i got the iphone 15 permanently gone now???
iPhone XS, iOS 17
