Hello,
I recently upgraded from a Galaxy S8 to a Galaxy S8 Active. The phone is essentially the same, with the same Snapdragon 835 processor and Adreno 540 GPU.
Big visual issues happen, everything is low resolution and blurry (especially special attacks and even characters). Cable is a big one; his sp1 is awesome on my previous phone, but the new one you can barely see his attack and it looks like something from 10 years ago.
I took pictures of Dormammu (the most obvious difference I saw).

Pretty bad in my opinion. Any reason why this is?
