Also, so much debris would be attracted to the screen like it was a magnet, and fingerprints were easily imprinted on the device. Now that I think about this, I'll probably stay with a screen protector but will give it a shot without one.
It's always good to try that imo. I recently tore off my iCarez protector and was shocked to see the clarity of the screen. I used it for a few days.
However, I like dark mode and I love having brightness around 10-15%. So trying to read a book with that much glare and seeing fingerprints again ... I put another iCarez back on. The clarity difference wasn't enough to bother me and my glare and ability to read for hours and hours came back.
Everyone's different. My wife can't stand screen protectors - so she doesn't use any - and she uses her devices more than I do.
