2. download Gravity box according to your Android gravity box available in various version for various plateform like jellybean, kitkat, lolipop, marshmallow or you can simply google gravity box for your android and you will see xda site first in search result download from there.
3. download xposed installer (search it like we did in gravity box) and after install of gravity box go to xposed installer go to modules and tick the gravity box and then reboot.
4. now open gravity box move down and here you will see Navigation Key Actions click on that here is a image available you can see it then click on under menu key double-tab action and choose go to sleep and that's it now whenever you want to sleep your phone just double click on menu button or you can choose any different button and set it according to your needed here is lots of future play with it be carefull and if you want you can too assign a app on any specific key like when i press home key for a while it opens a specific app i hope you guys got it so keep it up
