I'm trying to update (Documents to go Main app) in my device.

When I'm trying to install it an error comes out says an existing package by the same name with a conflicting signature is already installed.

I have root access on my device. Is there anything I can do?


Question: Is it better to scan negatives or prints?
Answer: That depends on the print.

Is the print just a simple print, or has processing been applied, e.g. filters to enhance contrast, burning, dodging, etc. Then I would suggest that you scan the print, if this is the version you like and want.

Otherwise, I would scan the negative.

E.g. Had I an Ansel Adams negative, and the corresponding print, I would certainly choose to scan the print.
