Im having a weird issue after the last update pushed to my phone, which is weird because my wife has the same phone and did the same update and shes not having the issue. Kind of hard to explain but ill do my best. Ok, so when my screen is off and I get a notification like a text, normally i would wake the screen and i would have the notification there where you could then swipe to open or tap that notification to "select it" then swipe to open to that app. after the update, its real squirlly. if i tap the very top of that notification itll select it, if i tap towards the middle or bottom (of this very slim notification) itll act as if the screen is unlocked and bring down the whole notification bar, the one that shows date, the quick launch buttons and others. From there you can still tap the notification and open it, but its just way more of a process. This happen to anyone else? I even broke down and did a factory reset but it still does it
I would recommend taking the device to your carrier or a Samsung Experience center so they can get a hands-on look at your device, as when we test our device it performs the same way you are explaining.
I am having the same exact issue, happened as soon as I installed the system update - very annoying problem! Additional, I am noticing when paired to a bluetooth playback device unlocking the screen or taping a notification will command a pause in the music player (google music)
