How to prevent android from automatically rearranging home screen icons? I don't know in which which version of android this has been added but it seems like a really frustrating feature. 

Once I delete an icon on my home screen, every other icon gets rearranged automatically towards the left top corner.

This is problematic because some of my apps are placed in a way that is easy to access with right thumb. 

This means that every time I remove something from my home screen I need to manually rearrange all the icons back to how they ware, and I can't seem to find a setting that would fix this. 

Version of Android - 6.0.1
But the same thing was happening in 5+
The smartphone I'm using is Sony Xperia Z3 compact.
As to the launcher I'm not sure which one Sony uses.
Apps > the more button (3 dots placed vertically) > settings > turn off "automatically place icons together"
