Hi my exported game is extremely blurry on Android, I tried scaling everything differently, increase the font size, change to TextMeshPro, etc and nothing helped. Here are my settings on canvas :
How do your quality settings look?
From that picture it seems Android defaults to medium, which probably is set to lower res textures.
Not your fault by the way, the Quality settings are notoriously badly designed.
I just set everything to ultra, its still happening 
Try setting medium to texture quality full.
Tried it, still pixelated/blurry. Now I remembered, when I exported the first testing version to my phone it was just fine, but later on I changed some setting elsewhere, related to this, I just dont know where… Do you have any ideas what could it be please?
Maybe player settings and you enabled some sort of resolution scaling?
Yesss that worked thanks buddy 
Please what resolution scaling did you enable I’m having same problem
If I remember correctly I meant he should disable it, since it was probably scaling things down way too much and making things blurry.

Worked for me as well
