Hello! Thank you for your question. I will be assisting you today.I'm sorry about the issue. It looks like it's just a glitch. If you have a leather (or any other) cover on the kindle, please remove it. Then please press & hold the power button on the kindle for about 45 seconds, then turn it back on and check.Please let me know if there is still any issue.
Edit: Please let me know if you still need help with this. Thank you,
