Default [Q] pull down notifications don't work in landscape.

In have a strange problem with my n5100 note 8. The pull down notification bar works in portrait mode and in landscape orientation when the home button is on the left. If I turn the note to the other landscape orientation with home button on right the pull down stops working. This is only true when using my finger. If I use the S Pen it works in all orientations. I have tried a factory reset which did not help.

something that may be related is at random times the screen will stop responding to my fingers all together until I put the device into standby and wake it. When this happens the S Pen still works as normal.

I have booked the device in for a service but I have to drive a few hours to get it sorted out and would like to avoid that.

anybody had this issue?
