Android: Your phone’s default layout caters to the right-handed user.
First you gotta get into your developer options, then you could initiate the layout change.
Here’s how:
Go into controls > About Phone.
Scroll down until you see “Build Number” and tap it seven times in quick succession.
This will enable developer options (if they’re not enabled already.)
Scroll down and tap the box to enable “Force RTL layout direction”.
In addition, you’ll see the layout direction of your home screen has changed.
