Large PDFs LAG like crazy on android!!!!!
Project Butter does not seem to extend to apps. They lag. If you’re using the Nexus 7 for work, I hope you don’t have any large PDF files to work with because you’ll be tearing your hair out. - mackadvs in this comment
I hear this complaint a lot on these forums. I've personally seen it happen on a Nexus 10, and it isn't pretty.
It very smooth for large PDFs on Nexus 7 and 10. If you scroll incredibly fast, it may struggle to render the page, but it will not "lag."
What other tablet-optimized PDF reading apps have you had a good experience with?
