Google just made it easier to transfer virtual libraries to Play Books, now that you can upload digital tomes straight from Android phones or tablets. Thanks to the software's latest update, there's no need to go the Play website to add EPUB or PDF files to your account. Simply click an e-book through an Android file manager -- or download it if it's attached to an email -- to get the "Upload to Play Books" prompt. The refreshed app also promises to open files more quickly and smoothly, although we didn't notice any significant upgrade in speed when we tested it out. Other than these two changes, the latest version lets you read any book in landscape mode and comes with the ability to dismiss recommended titles. Finally, you can now take the reader's brightness down a notch to make reading in the dark easier for the eyes.
