    Locking a PDF form post signing and filling. [Android]



      I have created a PDF form for our service engineers, and it works well with your Android app re customers signing on site.
      However, when my engineers send the signed PDF it can be altered, and the form fields changed by anyone who opens it with PDF reader.

      How can I “lock” PDF forms once post filling and signing with your Android APP…?

      I see from hundreds of people, in various forums, including Adobe’s forums, that this is a problem.

      Any help or advice would be appreciated.
