Lost scan, unable to save files

Hi @Dr. Ali haide28274772eplw,

Hope you are doing well. Sorry for your experience with Adobe Scan.

If the application crashes, you should get a message stating whether you want to continue with the last scan or create a new document. 

The crash here signifies that the device cannot render or process so many pages at once, thus causing the crash. I would like to suggest, going further, scan pages in small numbers to prevent over-processing of the phone's processor and prevent crashes.

If you did not receive the pop-up for the continuation, I am afraid, you will have to re-capture the scan.

Hope this clarifies your question.
