An update is rolling out to Dropbox users on Android, one which includes a built-in PDF viewer and an in-document search feature. For those who view a lot of PDFs on their phone or tablet, Dropbox allows you to share the file straight from the viewer, which will automatically save it in a Sent folder. This will make sure you don’t lose track of those important documents.
In addition, in-document search will allow you to find specific keywords within any document. For example, if you are looking over a 10 page document, looking up a specific word can help you track down the select part you are looking for. No more fumbling through pages in search of a particular section.
The update is currently rolling out to Google Play now, so be on the look out.
