I am seeing a difference between what TalkBack reads out loud when a screen is displayed on a Nexus 7 (4.4.2) and a Samsung SGH-I317 (4.1.2). 我发现在Nexus 7（4.4.2）和Samsung SGH-I317（4.1.2）上显示屏幕时，TalkBack会大声读出内容。

On Samsung SGH-I317 (4.1.2) when a screen is displayed some elements are read out loud but not all of the elements displaued. 在三星SGH-I317（4.1.2）上，当显示屏幕时，一些元素会被大声读出，但并非所有元素都不受欢迎。
On the Nexus 7 (4.4.2) TalkBack reads only those elements that are specifically 在Nexus 7（4.4.2）上，“话语提示”仅读取那些专门用于
selected/tapped. 选择/分接。

Is this a Samsung/Nexus difference or an Android 4.1.2/4.4.2 difference? 这是Samsung / Nexus差异还是Android 4.1.2 / 4.4.2差异？

What is the expected behaviour when a screen is displayed, should TalkBack read all the elements on the screen or just read what screen is displayed and leave it to users to touch a UI element before it is read out? 显示屏幕时，预期的行为是什么？“话语提示”应该读取屏幕上的所有元素还是只读取显示的屏幕，然后让用户触摸UI元素，然后再读出？

Android 4.1.2 (early JellyBean) and 4.4.2 (KitKat) are significantly different versions of the Android OS and you should expect different behavior. Android 4.1.2（早期的JellyBean）和4.4.2（KitKat）是Android OS的显着不同的版本，您应该期待不同的行为。 Additionally, unless you have manually updated from the Play Store, the devices will be running significantly different versions of TalkBack. 此外，除非您从Play商店手动进行更新，否则设备将运行明显不同的TalkBack版本。
