Turned on a brand new Verizon HTC Desire 530 today. There were actually two updates. The first was a 6.0.1 security update. The only thing i noticed was it went from security patch level June 1, 2016 to OCT 1, 2016. After that it popped up the 7.0 update. Here are some screen shots before and after update. If you're interested in any other info just post or pm thanks.
This was stock before any update
