On my iPhone 7 Plus anytime I’m in the notification centre or on the lock screen any touch inputs I make are delayed, so if I were to click the pause button on my music it pauses about a second or two later, swiping to the widgets section is impossible and 3D Touch doesn’t work for the notifications. Is this a bug in 12.1 beta 3? Or an issue with the device itself? I don’t remember this being an issue when I was on 12.0 or 12.1 beta 2.
