How to Disable or Reduce Undo Notifications in Acrobat Reader Mobile
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.
Before you start

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.

Solution 1Recommended

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.

1
Enable developer mode

Go to your device's Settings, navigate to 'About Phone', and tap the 'Build Number' seven times to unlock Developer Options.

2
Access developer options

Return to the main Settings menu, locate 'System' or 'Additional Settings', and open 'Developer Options'.

3
Adjust animation scales

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.

Operating System Limitations: Depending on your specific device manufacturer and operating system version, you may not have absolute control over toast notification durations.
