Kindle for Android has been updated to 3.4.2. The update includes:
Tablet users – read more text per page with improved margins and line spacing
Fixed several issues that were causing crases on some devices
I can definitely see a difference on my Samsung Galaxy Nexus running Ice Cream Sandwich. It gives me more options than I had before in respect to line spacing and margins. I never experienced the crashing problem they mentioned.
When are they going to add the ability to change the default dictionary, and the ability to use collections?
