    Description

      All animations set to a duration of 1 second run in 0.5 seconds on a 120hz Android device.

      QAndroidPlatformScreen does not implement the refreshRate() function and it's base class simply returns 60.

      This affects newer devices like Samsung S20 and OnePlus7/8 Pro.
