Hey there! Hope these two storage articles can help!:

If not then they’re maybe a technical reason the storage will not respond, if so, I may try a force restart and try again:

Otherwise, if the storage is accurate, but there’s not enough to support all the content on it, these articles may help:

Hope all goes well, otherwise if you needed to, you could backup and restore your phone from a backup, or as new:

Backup:

Restore to factory settings:

Restore from your backup:

https://support.apple.com/en-us/HT204184

on a side note, every once in a while, when having an issue, erasing and restoring the same backup may bring the issue back, unless it is an issue with the operating system, (iOS), that’s usually not a problem. Otherwise, setting it up as new, and restoring the data by signing into your accounts and re downloading your data, and setting up your preferences would need to be done.

I know that’s a lot to take in, hopefully, and most likely the first few steps will fix your issue, hope that’s the case! If need be you can always call Apple Support though, they can also help!

Off topic.. friendly advice..

it could help the readability of your post if you used the link function at the bottom of the reply window..

1. type some explanation text prior to your link, press enter
2. go to the other tab/page you want to point the OP to and copy the url from the address bar
3. back here in the reply window click the little chain link icon at the bottom
4. paste the url into the box that appears when you clicked the chain link
5. now the chain link has moved to the left side of the field.. click it again.. give it a second to populate
6. now your link automatically shows the title of the page 👌

sometimes it's buggy and doesn't show, but for me.. works 99% of the time. Also note that this only works with Apple support stuff.

I didn't figure this out until I was level 2/3 and I basically had to figure it out myself. So hopefully this is helpful to you!

Hey Chris0107! I appreciate the feedback! Without disrupting this post any further with this subject, that’s good to know. I’ve been an Apple user and troubleshooter for many years, literally joined about a month ago when I saw a close friend posted a question, and find it awesome! Anyhow when I have time, I usually use my iOS device to check emails and visit this site, not my Mac, Unfortunately I don’t see the chain link option, (Unless I’m looking too closely to see it! 🙂) Either that, or it’s an option for browsers on computers, appreciate it though, if it’s here, I’ll find it at some point, I was wondering about that too! @Listenerman, hope those answers help out! Let us know otherwise, happy to help out!
