Adjust behavior of MobileAccessibility.updateTextZoom and MobileAccessibility.getTextZoom
Adjust behavior of MobileAccessibility.updateTextZoom and MobileAccessibility.getTextZoom so they both return the correct updated zoom value to a callback method. Adjust behavior of isTalkBackRunning and isVoiceOverRunning so that they return true only for the appropriate platform.
