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

enter image description here

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.


This is a new feature in Windows 10 Mobile called one-handed mode. It's designed to help people using larger-screened phones reach the top of the display better (e.g. to open action centre). If you dislike this feature, simply don't tap-and-hold on the Windows key.

For more information about one-handed mode, see this article at Windows Central.

    You can resume to the normal screen mode by pressing the black part, or not touching the screen for four seconds – kelvinelove Oct 28 '16 at 23:13

    You can also resume normal screen mode by long-pressing the windows key again. – IROEGBU Nov 1 '16 at 15:19
