will let you know you guys..
hopefully it will get fixed.. if not we wait for an firmware update..
I used my phone all day using the settings above.. (no s-voice at home button and fingerprint lock) I encounter the problem 3-4 times.. other than that all is ok..
Now im going to use all day the pin to lock the screen and see what happens..
still the same issue with pin lock screen.. So probably an update will solve this..
