Hello!
I made a game but I didn’t select any resolution ( it is default, I see there ‘FREE ASPECT’ ) . The game works and looks good in Unity, but when I use Android Debug and I play the game on Android Device, the resolution seems to be so bad, the quality is too low, all the texts are pixelated. How to set a good resolution?
The “Free Aspect” is the resolution of your game window in unity, which is only used for testing and does not affect the resolution of your builds. To change your build resolution and aspect ratio settings, go to [Edit → Project Settings → Player], then expand the “Resolution and Presentation” section if it’s not already.
To prevent stretching and black bars, you’ll want to make sure the aspect ratio matches the dimensions of your screen. You can adjust how sharp/blurry the image is based on how large the resolution is.
Here is a good resource that explains in good detail how to use that window. The article is a little old, but it’s information holds up. http://www.aclockworkberry.com/managing-screen-resolution-and-aspect-ratio-in-unity-3d/
You may also want to check your quality settings and make sure your device isn’t using a lower-than-necessary quality level. Quality settings are in [Edit → Project Settings → Quality].
Good luck!
