I've had my Kindle Fire since the day it was released. (About 5 months). When I would play a game and then exit the game, sometimes there would be this burned image of the game on my screen sort of invisible. I thought it was a just a glitch, so I'd restart my Kindle and it would be fine.
But then it started doing it with other things. Sometimes the search bar would burn into the screen & the navigation bar, so that when I rotated my Kindle I would have 2 dark stripes running alone the screen and if you looked closer you could see the ghosted icons. That wasn't going away even when I would restart. I would sometimes get the keyboard burned into the screen, or the icons on your home screen. It was getting really irritating. I tried to doing a factory reset which wipes out everything from your Kindle Fire, but that did not help. The ghosting was still happening.
I searched for the issue on the Amazon website, on their Kindle Fire Help Forum. There was topic about the ghosting and burned images. It seems a lot of people are having this issue. It's some sort of defect with some of the Kindle Fires.
I contacted Amazon by using their 'Contact Us' button. They must be there 24 hours because I called on a Saturday night at 9:30pm. The customer service rep asked if I had done a reset (holding the button down for 20 seconds). I told him I had done a factory reset and that hadn't resolved the ghosting on the screen.
He told me Amazon would send me a replacement. I just had to send the damaged one back in the box of the replacement with the prepaid UPS label they would email me. They ask for the last 4 digits of one of the credit cards on your Amazon.com account. If they don't receive the damaged device back within 30 days they will charge your account the full price for the Kindle Fire plus shipping.
My replacement Kindle Fire arrived in 2 days! (So I didn't have to go through Kindle withdraw too long, hehe!). Then I packed up my old Kindle and we dropped it off at a UPS store to be mailed. Amazon got my old device back within 2 days also.
Soooo... just beware my Kindle Fire fans. This is an issue with some of the devices. If your Kindle is under warranty Amazon will replace it. My 2nd Kindle Fire is working perfectly and I hope it does so after 5 months of use. Hopefully there will be no need for anymore replacements!
