No downloading/installing properly for me. Started the download, all ok, went back to check it about 5 mins later, no indication I ever started an update. Go back into settings, tap phone update and end up with the picture below, won't open "phone update", bar just goes grey. Phone is unresponsive to many touches but does eventually go back to the start screen, but update is not happening it would seem.
Now restarted the phone, and it says there was a problem downloading the updates, trying again now, download currently at 93%.
Will update this post with my progress.
Cogs now, about 60% of the way through.
