Cox over data xbox one?

Ok so can I change all these options on my android tablet? Not each time I'm on YouTube but for all time usage, if doing this does it change data usage?

No unfortunately you would have to change it for every video. The apps set the resolution based off of your speeds then have to be adjusted each time. Unfortunately that's how the devs designed the apps. That would also include the android app. I struggle with
keeping my data down also since I also have capped data. The big struggle for me or these updates on games. Many of them reaching 21GB or even larger, and with 2 xboxes. Most games updating almost weekly. Add that with the 20 to 30GB a day we use as a family
watching videos starts to add up really quick during the month.

Are you asking how to change settings to use less data? With youtube you can lower the quality of the video. This can virtually be done from any YouTube app. On your xbox when watching a video you can change resolution from the more option and choose a
lower quality. Should be similar from any other youtube app on other devices. The more option on you xbox app will be the three ellipses.

Yes we cant afford any other is there other options to control my xbox one through my android tablet if not where in settings do I change all my options ty

To increase your Data limit. You will need to talk with your internet service provider (COX). I had COX when I was in Kansas and they can be a troublesome company to work with but they can increase your data limit so you can have faster speeds, more upload/download
etc.

Hope this helps.
