local pdf also goes blank. Is there any solution?

[santosh.sutradhar7]

I have downloaded a file from internet a month ago and saved to my mobile phone with its original name. Now it goes blank. I tried many pdf viewer but in vain. File size is showing, but opened as blank. Is there any formula to change it dynamically?
