I'd like to find a screen protector that literally covers every mm of the glass. Ideally what I'm looking for are no gaps discernible between where the protector ends and the surrounding bezel begins. I also prefer the sensors and camera to be covered but realize the ear speaker can not be. I've tried SGP and Green Onions so far. SGP is a much better fit than Green Onions but I'm looking for as close to perfect as possible. What has been your experience regarding precise fit?
