Images and Text are blurry (UMG) in iOS build when making a build from UE5

I made a project with 4.27 everything works fine. The UI looks sharp on iOS and android devices. But after porting it to UE5 the UI looks terrible, especially the text on iOS devices. I am not sure what the problem is, On 4.27 it works fine with default settings but not on UE5. Even if i make a new project on UE5 with just a text and an image it shows okay in editor but on device it is blurry. Kindly someone guide me is there something else needed in UE5 to make it work?
