I would have been very excited about this Galaxy XR development a year ago but today I don't care to even scroll down the page. Google's recent Android bullshit(walled garden, killing roms) makes this a non-starter.
In fact I wonder if Android/Galaxy XR is secretly responsible for these horrible changes to stock android. No chance of a XR/real life adblocker ever becoming a thing if you can't install your own software and/or the largest advertiser in the world needs to OK it's existence.
