I have Android 4.2.2 on my Kindle Fire and it's worked fine for a few months. Now, though, when it's off or sleeping, the green exterior (charge) light stays on. It's dimmer than when it's charging (and it seems to take a charge fine), but when charging, the light doesn't change to orange like it used to; it's just a bright green. My problem, of course, is the significant battery drain when it's either off or sleeping.
