If you take a new mobile phone
Apps are arranged in disordered way.
There seems no option by which you can order the apps in ascending order for quick findings, when needed.

Moreover GOOGLE NOW adjusts icon of apps with background colour so that they are easily visible. It also adjusts size.
Also known as Google Now Launcher.
