There is no way to answer your question without a lot more information, such as what happens when you try. But here is something to get you started.
To update over the air from the phone all of these requirements must be met:
- You need at least 6 GB of free storage
- You must be connected to a Wi-Fi network (and not a personal hotspot)
- The phone must be charged to at least 50%, and preferably plugged in so it stays above 50% during the update
- The phone must not be in Low Power Mode
- The phone must not be connected through VPN
- The phone cannot be in Airplane mode
If you can't meet all of them you can still update using your computer.
