Smooth edges on android

In Unity my game has very good graphic but when I build and run it on my android phone i have this problem

You can see how the edges are not smooth.
My objects are all unity primitive shapes.
I try using anti aliasing but no result.


It’s definitely a quality setting. AA is only enabled for certain quality settings and I think Android games default to pretty low quality. You could try deleting the other quality presets apart from ‘Fantastic’ and run a rebuild. Do be sure to back up your project before doing that, though.
