Hi everyone, recently I found my iphone 6s lagging when I try to wake it up. All the wake up methods would cause it to lag, including raise to wake, lock button, home button. Even the silent/un-silient switch would lag. It does not happen every time, but it's quite annoying. Does anyone know why is this happening? Thanks a lot. --- Post Merged, May 30, 2018 --- BTW I'm running iOS 11.3 on my phone.
