I was wondering what you all think is the best accessory for preventing dust to get under the screen. I'm having a lot of dust issues on the sides and in the upper left corner. My phone is naked now. I want something to block the dust from getting under the screen if there is something. I had a soft case on it but it seemed that made the dust worse cause it stopped on the front right on the edges so the dust piled up on the edges. Any help is appreciated. Thanks.
