Anyone else who updated the 12L update and have screen issues? I just noticed it last night and now I can't unseen it.. it's like how placing a matte screen protector will give you a fine grain filter that is very obvious on white background? Except for my case it's mostly obvious on black background instead. I got my S8+ for over half a year now and I seriously doubt I could had missed this out for such a long time. Last night was the first time I used it after the update so I'm not sure if it's just a coincidence or it was caused by the software, as unlikely as that may be
