I really like the crisp, bright graphics of the standard screen, but I do frequently sit with my back to a large window that catches the afternoon sun. Rather than getting a permanent matte screen protector, I’m experimenting with a removable one. I bought this, hoping it would be a close fit on height. It was only $10 on Amazon.
Using a paper cutter, I trimmed the right side to bring the overall width down to about 9.5 inches and needed to trim the bottom edge up about 1/8 inch. The filter has (had) reusable adhesive strips along both sides (the right side was trimmed off). This filter is supposed to fix to the frame around the screen and works quite well to reduce glare. By trimming along the right and bottom sides, it left the notch at the top to expose the camera, but moved the notch to the right so the filter covers the brightness sensor.
The only problem now is that the remaining adhesive strip is not quite strong enough to hold the filter securely more than briefly. I need to come up with a thin, removable, reusable adhesive for the right edge.
