My Moto G4 + Skinomi that worked well for me is going downhill fast so I'm back in the hunt.
So far I have tried the Moto G6. The screen is terribad. Instant eye strain/facial muscle tension. Shipping it back
I tried a Nuu 2 Mobile. Cheap phone from China. Same thing, unusable. Shipped it back.
I found I can still get a lower spec G4 on Amazon, I ordered it and another skinomi screen protector. We'll see what happens, I have had 2 versions of the same device act differently since manufacturers do not use homogeneous parts.
