Hi! I wanted to clarify the situation in more detail so it’s clear what happened.
The main storage on my iPhone was completely full. I tried to free up a couple of gigabytes, but it didn’t work, and all the photos in my gallery remained in place. To try to trigger the memory cleanup process, I restarted my iPhone, as this sometimes helps. During this time, it showed “iCloud Photos Sync.”
After the restart, the storage was freed not by a couple of gigabytes as expected, but by tens of gigabytes, and my iPhone’s storage started behaving very strangely: it was initially 127 GB full, then suddenly dropped to 66 GB, then went up and down again — literally “jumping” on its own.
All the photos in the gallery disappeared, even those that are in iCloud, although I can see them on the iCloud website. Only a small portion of the photos appeared — the iPhone seemed to start restoring them on its own, but then the process stopped.
I had a 2 TB iCloud plan, but it was full, and new photos hadn’t synced yet, so not all new data was in the cloud. After this issue, I upgraded my iCloud storage to 6 TB in hopes of recovering the photos. Currently, my iPhone is performing “iCloud sync” and restoration.
Given all of this, is there a chance that all the photos will return to the device?
It feels like this is a real system glitch, because there were files in the gallery, and to remove such a huge amount manually, I would have had to delete them all myself — which I did not. The iPhone did this on its own.
