Stream Beta 1.0.7 (current version)
Samsung UN65fMU8000, version 1270 (current)
The location of the captions is placed in the vertical center of the screen on the left on all programming This is on top of the main viewing area. Should be horizontally centered at the bottom of the screen
Thanks for posting to the Xfinity Forums. Sorry for the experience you're having with the location of the Closed Captions when streaming. Unfortunately, we don't control this, however, I wanted to see if you could try adjusting the CC settings to see if this helps any? If you don't have this option in the Stream App, please try to make the changes in the Xfinity Stream Portal.
How can I adjust the text size of Closed Captioning online?
Within the Xfinity Stream portal, the caption text can be adjusted to small, medium and large sizes. To customize your captions, select the settings icon and then Customize Display under CLOSED CAPTIONING.
I hope this helps.
I know that comcast does not control the placement of the captions on the screen.
However, it seems not likely that every channel and every program decided to put all captionining centered on the left edge of the screen only for the Xfinity Stream app on Samsung TVs. ...but keeps captioning centered along the bottom of the screen for every other TV, set top box and Xfinity Stream for iOS
I understand and will be sure to pass along your feedback. In the meantime, depending on the type of device(s) you are using, can you let me know if this helps in your situation?
On Apple devices, you can change the appearance of Closed Captioning including font size, style, color, background color and opacity.
On devices running Android 4.4 KitKat or later, you can access Closed Captioning settings under your device's Settings menu. On devices running earlier Android versions, you can access Closed Captioning settings from within the Xfinity Stream app.
