Context

QtQuick Controls 2 Slider on Android Phone with TalkBack activated to fulfill requirements of WCAG 2.0 / WCAG2ICT

Expectations

• Value should be announced by TalkBack on value change by gesture

Observation

• Changing the value does not announce the value.
• Sometimes the value is announced with wrong/no rounding of the value.
