I have the LK screen protector installed on my AW series 9 and it's great; doesn't affect touch sensitivity, screen clarity, and you can barely tell it's there. However, I tried the Spigen Rugged Armor Pro case and it caused the edges of the screen protector to lift up and bubble. I applied the screen protector about as perfectly and evenly as I could. Are there any cases out there that fit perfectly fine with screen protectors without issue?
