How to Disable or Reduce Undo Notifications in Acrobat Reader Mobile
Question details
The user wants to disable or shorten the duration of the 'Undo' toast notifications that appear after reversing changes in the Acrobat Reader Mobile app.

- Product
- Acrobat Reader Mobile
- Device & OS
- not provided
- Scenario
- Reversing changes or undoing actions while annotating and editing a PDF document on a mobile device.
- Observed behavior
- Intrusive toast notifications appear on the screen to indicate the undo action, which cannot be disabled or reduced through the standard app settings.
Keep in mind that the duration of system-level toast notifications is typically managed by your mobile operating system, meaning application-specific settings may not provide a direct toggle to disable them.
Adjust Device System Developer Settings
Modifying the toast or animation duration in your mobile device's developer options might reduce how long the notification stays on screen.
Since toast notification timing is managed by the operating system, altering developer options is currently the most direct way to change how long these messages appear. Note that this process primarily applies to Android devices.
Go to your device's Settings, navigate to 'About Phone', and tap the 'Build Number' seven times to unlock Developer Options.
Return to the main Settings menu, locate 'System' or 'Additional Settings', and open 'Developer Options'.
Scroll down to the drawing or animation section and reduce the 'Window animation scale', 'Transition animation scale', and 'Animator duration scale' to speed up how fast system prompts disappear.

Since the current notification behavior is intended by design, you can request a change or toggle feature directly from the developers.

No, Acrobat Reader Mobile does not currently provide a built-in application setting to disable or modify these specific undo toast notifications.
Are there alternative PDF applications that do not show undo notifications?
Yes, alternative productivity applications like WPS Office handle PDF annotations and undo actions seamlessly natively, without pushing disruptive system-level toast notifications to your screen.
