Well today I noticed a 1/2 inch scratch on the left hand side in the horizontal position. This also happends to be we're I slide my left thumb to scroll up/down pages. Anyways with LIGHT pressure I moved my finger side to side across the scratch to verify it was a scratch. And then the unthinkable happened. Thier is now deep scratches going in the same direction that I moved my finger across the scratch . I can see the "trail" exactly of we're I moved my finger across it. So my conclusion is that small glass particles can become dislodged from the scratch and caught under your finger then dragged across the screen causing more scratches. Keep in mind this happened within 3 seconds so the only preventative measure would be to not touch the screen scratches or use a screen protector. Anyone else have a problem like this.
