Given the majority of issues experienced in attempting to open/view a PDF form on a mobile phone are normally related to opening and viewing read only PDFs, this article provides the reason/s why interactive/fillable Javascript enhanced PDF forms created in Adobe Acrobat are not intended for and as a result fail to perform on a mobile device/phone to begin with. In reality, the answer is altogether quite simple and easy to understand for those well versed in Acrobat Javascript (JS) methods required to provide never-before-seen form features an EasyPDF™ form has to offer. In short, the JS methods alluded to herein were primarily created by Adobe for interactive PDF forms created in Acrobat, whereby many (but not all) are designed to work on a Windows 10/11 or Mac desktop/laptop computer running the Free Adobe Reader version 2020 or higher. Unfortunately, in order to use an EasyPDF™ form or other JS enhanced PDF form created in Acrobat including all features provided, once again the PDF form will only perform using the Free Adobe Reader installed and running on a desktop/laptop computer. Moreover, the JS methods created by/for Adobe Acrobat are proprietary to Acrobat and as such a JS enhanced interactive PDF form created in Acrobat will normally fail to perform in any other PDF creation tool or reader on the market including but not limited to PDF Filler, Foxit PDF Editor, etc. Pure and simple there are none! In short, if you're searching for features in a digital form comparable to what an EasyPDF™ form has to offer, you're literally wasting your time. Truth is there are none!
