Kindle Fire - Not Responsive to Touch
The screen won't respond to my fingers at all.
The screen is frozen
Frozen screens can be very frustrating. Similarly to computers, our smaller devices can freeze up. Your Kindle may have frozen, so reboot your device by holding down the power button for 10 seconds and letting go. Once your Kindle shuts off, turn it back on. If the screen was just frozen, restarting the device should fix the problem.
The screen is damaged
If your screen refuses to respond, no matter what, it may be damaged. Try to see if you can spot any physical damage on the screen before you determine if the screen is broken (any damage that impedes the use of the device is too much. If it is, you will need to replace the screen.
