Problems updating iphone 6s to ios 13.2
Need help updating iPhone 6s to ios 13.2. It apparently has downloaded a significant part of the update. It started out saying "about 4 days left." This went down to "about 1 day left" in a relatively short time. Now it is stuck on "Estimating time remaining . . ." and won't complete. Have tried rebooting phone a few times to no avail. Anyone have an idea.
Thanks
iPhone 6s, iOS 12
