The second thing I'm noticing is 2 dark vertical lines while watching movies that have dark scenes. I am used to all my tablets having some minor screen issue but I'm wondering if anyone else is seeing this. You can really see it in dark blue backgrounds like the settings menu. Everything else about this tablet is great!
I had a similiar issue with my 8.4 and my 64 GB micro SD card that I noted here - http://forum.xda-developers.com/show....php?t=2799399
I haven't had an issue with my SD card files being unreadable since I exchanged it for a new one. The weird thing is on the original one that wasn't working was that it was missing the clear tape around the edges and there were some scratches around the SD slot. The box was sealed and I bought it the first day at Best Buy (6/27) so I don't think it was a re-stock, but it was still weird. Also, the original bad one had a brown picture of the tablet on the front and the 2nd one that I don't have an issue with had a black tablet on the front even though it is still brown.
I haven't noticed any vertical lines though.
