I bought my Kindle 3 wifi/3g about 3 months ago. 2 weeks ago I noticed that if I press down on the "frame" area around the screen near the page turning buttons on the right side, that it appears as if the glue is not quite tight? Sometimes it makes a pop noise like it will stick and then wont move again until I use it again. I know this sounds confusing, but I dont know, it seems like the glue holding the area I mentioned is not quite sealed properly. Should I call customer service? I bought this particular Kindle from Bonanzle (kind of like ebay) and so I am not sure what they will say? My k2 never had this problem. Has anyone else noticed this before?
