So far personally I'm not a fan of the lock screen changes. I had to turn off the lift to wake because any time I slightly move my phone at night it is very bright. Because it's a beta I'm having some issues with mail, safari and Facebook crashing. Having lots of issues with Siri too. Way too quick to tell me she didn't hear me when I have had less than 1/2 second from the time I press the button. Notifications are too big and not as easy to dismiss. Might be going back to iOS 9.3, and staying there. Any other opinions so far ??
