I just received a "[3 Pack] LK Screen Protector for New iPhone SE 2020 / iPhone SE2 / iPhone 7 / iPhone 8" from Amazon.
After working for 10 minutes to get the bubbles out, the screen works Perfectly.
I ripped out the flimsy plastic from the Otterbox Defender case, and so far I'm very happy with this solution.
I looks better and works better than Any of my previous Defender cases alone, which would always look like **** when I cleaned the plastic with 92% alcohol.
My only advice is to wait a bit before putting it inside the case. Some tiny bubbles may appear a few minutes later.
If I do see more bubbles, and the rioters leave my Apple Store standing, I will try Apple's Belkin screen protector solution.
They have a machine to apply the screen protector without Any bubbles, so it will probably be a better solution.
But with C19, Apple Stores closed, rioting ... yada yada yada - this will be quite workable for now and Massively better than before. I can scroll with just a feather touch, just like it should work without a screen protector.
