Hello =) The title says it all: do Kindles ever get firmware updates? I've had issues on my Kindle that went away on their own and a friend suggested it might be due to a firmware / software (not sure what the correct term is?) update that introduced a bug that was removed in the next update. But that would only be possible if there are updates to begin with =) I have a 4th gen basic Kindle if that's relevant. Thank you ^^
Yes, they do!
In fact at this page you can find the update for your kindle (if it's not a kindle touch, then it's called kindle 5th generation), with the following information (bold is supplied):
We have a new, free software update available for your Kindle (5th Generation). This update automatically downloads and installs on your Kindle when connected wirelessly; however, you can also manually download the software and transfer the update to your device via USB cable.
This means that, yes, it is possible that your Kindle automatically updated itself downloading the new firmware online.
