I received this item yesterday. The screen of this Kindle is not as bright as my old 6th generation one. Also where the screen is supposed to be white, it has a sickly yellow cast. Not Happy? I'm deciding whether to send it back for a replacement or to just give up and consume my Amazon content on other devices only. When I installed the micro SD card I got a message that the card was corrupted or incompatible with the Kindle.
