I am having trouble with my 6th generation Kindle Fire HD8 32gb. When I try to download a Book from my Kindle it goes to my kindle but freezes and will not allow me to open and read. I have to go to my main computer and reload from my Amazon account. Also, on Facebook, half of the pictures on any posting or all of the pictures are blanked out. Also, sometimes, my Kindle just cycles and cycles trying to access something using WIFI (even though it shows it is connected) and can't seem to get to the app. All of these things are intermittent and started happening about 6 months ago. Please any advice.
