When I press and hold the windows key in my lumia 535 (W10M-RM-1090) screen goes half and no matter which app I do open; the screen remains half.See the screenshot
Tapping on that empty space reverts screen to its normal size. When I was on W8.1 nothing happened on holding windows key. Any solution? My phone is 535 DS running W10M (build 10.0.14393.693) if relevant.
