Model: IPhone 7
Total Storage: 32gb
I'm having the same issue here too. It suddenly started saying the storage was full (even though i had just checked it a day or two before and I had 16gb left of a 32gb IPhone 7). I went ahead and deleted apps I wasn't using and cleared out my photos, went through the IPhone recommendations of deleting large attachments, I even bought a subscription for ICloud storage (I never had it before, but I figured if I got that then all the storage would sync to there). None of those things freed up any storage space on my IPhone.
I then noticed that each time I deleted an app or a bunch of attachments, that the "App & Photo" portions went significally down but when it did the IPhone "Storage - Other" would get bigger. I can't even update the IPhones software or backup it up to icloud because there's no free space at all. I cleared all my website data & cache and that didn't do anything either.
Here is how much space each category is taking up:
Photos: 266 MB
Apps: 2.20 GB
System: 3.46 GB
Other: 17.99 GB
I'm hesitant to do a full reset because I can't even do a backup of the phone and I have a lot of work things on my phone. Anyone have any other ideas to try without resetting the whole phone?
