An upcoming version of the YouTube app for Android will let you set a preferred video quality for streaming. This feature was discovered in APK version 15.12.33 and given the all-caps “BETA” notes next to the new toggles, it seems that there might be a few bugs left to iron out.
Currently, YouTube has a default video quality that is set server-side. Speaking of, Google decided to reduce the global streaming quality, setting the default to 480p to free up bandwidth for other uses. Of course, while watching a video you can switch to HD quality manually, but the next video will start playing in 480p again.
Once this feature lands, you will have two separate controls for default video quality – one for when the phone is connected to Wi-Fi and one for when you’re using your mobile data. There’s a limited version of this right now, a toggle that defaults to 480p on mobile data and HD on Wi-Fi (well, it used to be HD, until yesterday’s change).
