My Facebook Instant game looks low resolution and blurry

I’m making a Facebook Instant Game and when played on Windows browser, the games look good. But when played on mobile messenger, the game just became really blurry and low resolution. Even the startup Unity logo and “Made with Unity” screen is blurry. I checked other messenger games and they look good.

Is there any solution to make my game look good on messenger mobile?
Thanks.

You can change the quality of your game.

Go to File ->Build settings ->Player settings ->select Quality.

In Quality you can change the quality of game from very low to ultra based on your requirement.

I think this will solve your issue.
