I've been reading around this subject for a few days, but I still have been unable to work this out.

I'm trying to develop a game in Unity for Android devices. I read a guide that suggested 'safe zones' that work for all aspect ratios, then have more decorative stuff around the edges which will only appear for some aspect ratios, but that wasn't for Unity specifically. I'm having trouble working out how Unity handles this on its own - does it automatically stretch the game? does it letterbox?

I have tried this 'safe zone' idea, however I come up with various problems where the game doesn't scale as I expected.

For testing, I have a simple background that appears on the screen; the safe zone is one colour, and the borders around the edge are another colour. In theory, on different devices I should be able to predict where I will see this second colour, but this is often not the case.

In short, how do I make a Unity game that will work with different aspect ratios? How does Unity do it automatically? And what should I be using to test it? (At the moment, I am using BlueStacks emulator, Unity Remote for Android, as well as building to my Android phone, but I never get the result I expected).

Any help will be massively appreciated, as I'm been getting quite frustrated with all the different answers I have found!

EDIT:

Specifically, the game I am planning to make is mostly about interacting with menus, so many scenes will be purely UI, and nothing in the worldspace. Or is it better to make it a Worldspace UI? Will that make scaling for different UIs easier.

Ultimately, I just want to display my game, without blurring, stretching, black bars, or slicing sections of the sides to make it unusable. Is this really difficult, or am I missing something? Is this as simple as designing my UI with a 'safe zone' that will work on any screen, with more decorative areas at the edges?

Something extra - the game will be locked in landscape mode, so that should make it easier.

I am trying to work out how to support various resolutions for my Android game. I have come up with a solution, but do not know how to implement it.

Automatically, I am told that Unity vertically scales the screen to match the screen, leaving more room at the sides. How can I change this behaviour? I am hoping to shrunk the game down till it fits horizontally, and filling it the background above and below with more decorative features. How can I achieve this?

I'm sorry if there is an obvious answer, I'm quite new working with the Unity UI system.

If it makes it any easier, my game is heavily based on UI, and is locked in landscape.

BIG EDIT: I completely rephrased this question because it was so broad and messy.
