Hello and welcome to the community 🤗
If you can’t install the update
- Your iPhone maybe required:
To be connected to wifi
To be connected to a power source
To have 50 % or more
To have more space
To see if your iPhone required that, see if you have a message at the bottom of the update or seed a screenshot.
