Lag when waking up phone...iOS 9.3

iOS 9.3 is a complete cluster. Phone was working fine until middle of the week when this update was pushed out, and now my phone has a 2-3 second lag whenever I try to "wake" it by either pressing the home button or the on/off switch.

The problem is, half the time the phone thinks I'm trying to activate Siri (I'm not) so instead of the Touch ID working, Siri comes on. I have tried a hard reset, a restore (that took forever thanks to Apple's buggy app update process) and have no other ideas.

...and I STILL can't add cards to Apple Pay which were removed when did the restore.
