An update to Adobe Reader has just dropped in BlackBerry World for BlackBerry 10 devices. This new update brings built-in document signing and text annotation to the app.
NEW! Signature Support - Easily 'sign' documents with Adobe Reader signature support. Quickly create a signature, save it and then place the signature anywhere on a document! Now - move, resize and adjust color, opacity & thickness of a signature, too.
NEW! Text Annotation - easily insert any text using the Text Annotation Feature in Adobe Reader. The annotations can also be moved, deleted and adjusted for opacity, color & thickness.
