Try this: click 'share image' in Camscanner, choose any option (I used my email account) and cancel. The pix should appear in Saved Pictures in the Photos hub.
Have you updated to the latest v2.3? The option for saving images to photo gallery is much more obvious now. You can access all methods of sharing, saving, uploading, or exporting from "share"
Hi I went through this and I found a solution and I want to share it with you guys. To copy or move your scanned files (Images or PDF) go to programs in your android phone then My Files, All files and from there to the Device storage and select CamScanner. Select the files you want (or select them all by choosing the phone settings button (bottom left)) and select the TOP right corner bottom and choose move or copy and then a window appears choose where you want your files go.
