Canvas scaling blurry

So I'm working on a game and I decided to use canvas scaling. Easy, right? Well, I set the default resolution to 1080p and everything works perfectly when I'm in the editor. However, when I export it and open it on android it looks like this.

Note that this isn't blurry because of the upscaling on pc, it actually looks like this on my 720p android phone. I set the UI scaling to "scale with screen size" and set the resolution to x: 1080 and y: 1920 because my app is portrait. Does anyone know how to make it not blurry? Also I am using textmeshpro if that matters.
