This is the tablet for application. I left mine aside for about a week and now, when everything works on the tablet, the aplication reading Kindle books I bought was "stopped". I guess it is because of the update you are reporting. Anyway, I sent "reports" to "reports" without success. So, I uninstalled the application Kindle in the idea of reinstalling but your website does not offer me the store, I installed, and where I can find nothing to read my books. I ask you: 1) How to restore the Kindle for Android on my tablet? 2) And secondarily, how to adjust the brightness myself when I read a book. The automatic adjustment of the application is aberrant. Thank you,
