Not 100% happy with my Kindle 8.9 HD

Several apps that worked fine on my old Kindle Fire are not working correctly. Two have display problems, one isn't responding to the touch screen. Another takes up only about 2 square inches of the screen. It used to be full screen. Not crazy about the fonts for the e-book reader, either. They need to be bolder. (I know, that is a personal preference thing.) Some keyboard inputs don't have auto-complete. Can't believe it didn't come with an AC charger, especially when the very first thing it wanted to do was update its software and warned "Be sure to use an AC plug to ensure ... " something or other so it didn't run out of juice during the update.
