i have my 6s for 2 days now on ios 9.2. I notice that when i wake the phone the lockscreen doesnt pop up instantly.. It takes like 0.5 sec. It bothers me, because when I do it immidiately after again, it responses instantly. So, it seems like if i do not use the phone for 1 minute or more it takes a little longer to wake up... I hope nothing is wrong with my 6s do others have this too?
