Screen protector suggestions?

[BParker99]

Hi,
I recently got a spigen rugged armor case and a tempered glass screen protector for the xperia xz premium. The case is great, but the screen protector is causing a halo effect in thin bars on the sides of the screen. I am guessing this is due to a slight curve in the screen, and is really bugging me so does anyone have suggestions for a better fitting protector that will still work with the spigen case? (as a side not I don't want to use the oil trick to remove the halo effect)

Thanks!
