So I've been reading some of the thread about switching to android, and one of you mentioned ABK. So, I am asking, since I have an Amazon fire tablet, is it possible to use ABK with VoiceView? I know Amazon has their own braille input, but I've been having issues with the default stuff Amazon does. I know it's usable with any screen reader, but as we all know, Amazon changed their stuff immensely, and I've come here to ask, because if I don't know, I could break it! Which is what I don't want.

You will not break anything by trying and switching off in case of error.
I never used amazon products but give it a try and tell us does ABK work there.
And again, you will never do something irreversible by just installing and trying a program on non-rooted android device.
Just uninstall if you have any errors.
