I have been using the scanner feature on my Android device to create PDF documents for quite a while. After a recent update, the scanner is creating distorted files with pixelation when I use the Black and White scan setting. I have viewed the documents on other devices in other apps and the problem is the file that the Dropbox scanner creates. I have tried other scanning apps on the device and the scans are fine. Has anyone else observed this problem? If so, is there a solution?
