YouTube for Android will soon give users the option to choose default video quality on Wi-Fi and mobile data

For now, you can modify the video quality by choosing the resolution directly and on the video itself. The update brings a new simplified menu, where you will have three basic options: Data Saver, which, understandably, delivers lower-quality video, Higher picture quality, which will always display video in 720p and up, and Auto, in which the YouTube app will determine the video quality instead of you. Additionally, you can go for the Advanced option and pick the exact preferred resolution.
These settings are present on every video, but you will also be able to set default preferences in the app. In the YouTube app's settings, you will have a new menu dubbed Video quality preferences, which, as you can see on the screenshot, is still labeled as beta for now. It offers two settings for the default quality of videos on Wi-Fi and on mobile networks. There, you again have the three options: Auto, Data saver, and Higher picture quality. Unfortunately, you are not able to pick the exact resolution for the whole app yet.

We don’t have information on when this feature will be available to the public at the moment, as it is still in beta, but it's good to know that YouTube is working on it, as it will be helpful for people on limited data plans.
