I have a Ringke Fusion X on mine.
I really like it,you can see the color perfectly
I also have a Spigen neoflex as Screenprotector and i Highly recommend this
i might switch from my S10+ to the Ultra.
They only reason im holding back is that my S10+ looks brand new after 2 years and i will pay 35 euro less every month with my telephone company if i stick with this fone.
but on the other hand i love new gadgets 😁
Well I've always used a Spigen case on my S7E for 2 years and my old telephone looks brand new,so when my Note arrived yesterday the first I bought was a Spigen Slim Armor
