Hi @k_p95, you mentioned that before reinstalling iOS, we'd need to create a backup to iCloud. The problem is (for me and many others I am finding) that backups are IMPOSSIBLE while this issue is happening. I have tried backups using iCloud, iTunes, Finder (on my Mac and MacBookPro), via wifi AND cable, yet every time the backup attempts fail after hours of messages like "Waiting for data transfer" and spinning animated icons.
So I cannot create a backup at all on my iPhone Xs and this is where we hit a brick wall when it comes to reinstalling iOS or otherwise attempting to salvage data from an iPhone suffering from this issue.
My VoiceMemo app is showing that it is taking up 12.31 TB (yes, terabytes!) of space... and this is on a 256GB iPhone Xs, so clearly this is some nasty software bug.
After all the headaches and literally hours I've spent with Apple (in-store and on the phone with support cases), I was still unable to create any backup and therefore unable to restore my new iPhone 13Pro "from a backup".
I was able to rescue all of my photos by syncing those to iCloud, but nearly two years worth of text messages (and all pics+vids associated with them) are missing in my iPhone 13Pro... partially my fault for not creating full backups on my Mac for the past two years. Clearly this bug originated between my last successful backup and today.
Today, I tried to both DELETE and OFFLOAD the VoiceMemo app data from my iPhone Xs. During the approximately two hours of each attempt, the phone gets extremely slow-to-respond, heats up, then kicks me out only to leave me where I was before . Frustrating beyond anything!!
Anything else I can try to get rid of the "12.31 TB" of Documents & Data in the VoiceMemo app??
Appreciate it if anyone else has more ideas!
