storage is full on iPhone 12 and its stuck on a boot loop

Hello Lupegarza12,

Thank you for using Apple Support Communities. Based on your post, your iPhone constantly reboots due to a lack of available storage.

To confirm, you aren't able to create additional storage space when it powers on: How to check the storage on your iPhone, iPad, and iPod touch

If it won't turn on, try: If your iPhone won't turn on or is frozen

In case it does power on, but only to the Apple logo, see: If your iPhone is stuck on the Apple logo

Let us know if this helps out or not, take care.
