Hi all,
I have K3 B006, my kindle keyboards acts like the Alt key is pressed all the time.
Top row keys types numbers. Home take me to the Amazon store and so on.
I tried all including Factory reset.
Do someone have an idea what to try? Is it possible to disable alt or physicaly disconnect alt key?
Even disconnect battery did not helped (I found this on internet as solution with similar problem)

Thank you a lot.
Ales
