Please give me instruction step by step please.. If you want then you can show me video tutorial... thanks
again, I am so sorry if I come off abrasive. it must be your nationality and the structure of your language which is making translation difficult. I have seen you posting an awful lot here lately and sometimes wonder if you are just trying to boost your post count for whatever reason.
anyway, regarding your issue you post about here.........
first of all, I have yet to see you post as to your specific variant of device. if it has anything to do with how this option is activated, you never know, specifics can sometimes mean the difference. you sound as if you don't even know your own device.
as previously suggested, use the 2 finger dropdown to open the toggle option. you should see a marker of sort appear on side of your screen. tap that and applications will then be shown. press on an app, then drag and drop in upper or lower half of screen. so simple, even I figured it out.
if you need a video..........run a search. I did on Youtube and 4 videos cames up.

your supposed to be a senior member here.......put your self in a position to help yourself first. if you still have difficulty, folks can tell and are more than happy to help. I don't get the impression you are doing that.
I am no master here by any means, but more often than not, I can figure things out.
good luck and if your issue is solved, please post in your heading.
