Enjoying multitasking on my rooted zenfone max. Here i am going to tell you procedure how to do this:
1. You must be on marshmallow and your device must be rooted.
2. You must have a file manager with root access. (i.e. root explorer)
3. Open root explorer, go to system/ build.prop
4. Open build.prop and scroll down to end, now add a new line at bottom
persist.sys.debug.multi_window=true
5. Now save it and reboot phone.
Multitasking is now activated on your phone.
Now open 2 or more apps and tap on recent app key you will see a new icon near clear icon on. (see in marked ss)
Tap on it new icon, you will see 3 options as shown in ss.
1st is for top screen, 2nd is for bottom screen and 3rd is for full screen mode.
I hope now you will understand.
Thanks......
