Ive had its since friday and its been flawless. Tonight most of the time when I swipe to open I get animation stuttering thats bad at times. Ive tried a full reboot and that didn't help. Not sure whats happening here.
Seems to only happen if i try and do it fast. If I wait a second until the lock opens then swipe up I don't notice it. Don't recall it doing that before though.
This happens on my 8 Plus also, about once a day, and has done since day 1. It goes away if i re-lock, then unlock again. Also, there’s a slight judder to the force touch animations on the home screen.
