My iPhone won’t update to iOS 16

A question:

1.

Do you have a MDM profile?

If so, contact your company - IT department.

2. 

Have you install / use iOS Beta version?, if so remove the beta profile (Settings -> General -> VPN & Device Management).

Then Restart your iPhone and check for updates again.

3.

If neither of the above question applies, see ⤵️

You need about 6 GB device storage and good Service & Wi-Fi.

If they are On, turn Off Hotspot & VPN.

Charge the battery > 70%.
