Use Adobe Acrobat Desktop for Certificate-Based Signatures

Save the PDF document from your Android device to a secure cloud storage service such as Google Drive, OneDrive, or Dropbox.
Access your computer, open your cloud storage, and open the PDF using the desktop version of Adobe Acrobat.
Navigate to the 'Tools' menu at the top of the application and select 'Certificates'.
Click 'Digitally Sign' on the top ribbon, click and drag to draw a signature box, and select your configured digital ID to complete the secure signature.

Monitor Official Adobe Channels for Android Updates
Adobe may introduce digital certificate support in future Android updates. Tracking release notes ensures you get access to the feature as soon as it is rolled out.

Frequently Asked Questions
Can I use standard electronic signatures in Adobe Acrobat for Android?
Yes, while cryptographic digital certificates are not currently supported on the Android app, you can still draw, type, or insert standard electronic signatures using the 'Fill & Sign' tool within Adobe Acrobat for Android.
Will Adobe ever add digital certificate support to Android?
Adobe has not announced a confirmed release date for digital certificate support on Android. Users are advised to check official Adobe product updates, release notes, and the Adobe Blog for future announcements.
What is the difference between an electronic signature and a digital certificate?
