YouTube AdAway is an Xposed Framework module that removes country restrictions, branding layers, channel logos, video suggestions, and advertising banners from the installed YouTube app, leaving you with a video stream free of restrictions, advertising, and popups.
As the Xposed module requires root in order to function, this module will only work on a rooted device.
There are options for whether you want to block ads or just remove country restrictions, which you might want to consider when using this. Although blocking ads does sound ideal, remember that it’s taking money out of the pockets of whoever posted that video you’re so interested in watching.
It also probably violates the terms of service for YouTube, and probably the DMCA for the country restriction bypass, so check your local laws and ethics before implementing.
If you’re interested in applying this module and don’t have Xposed installed yet, take a minute and make a nandroid backup in case something goes wrong, install the Xposed framework from here, reboot, install the YouTube AdAway module (link below), and enable it in the Xposed app.
Also note that Xposed makes changes at runtime, so no modification to the YouTube application ever happens meaning updates should work later on, although it might break the YouTube AdAway module. It’s easy to disable any Xposed module, however.
This is certainly an interesting module that can save you some data costs and time, but try to be considerate while using it.
