Re: 1080p and 1440p play option on youtube
Pretty sure older versions of youtube it works, and a few months back they pulled HD video out of the app in an update. Anyone that has an older version of the app can still play it, new versions cannot. Some of these Note 4's might have a version of youtube that was before the update, and if some of you have auto update apps on, it might be updating it and losing the feature. A way to test it would be either uninstall updates on youtube and turn off auto app updates in google play and try that, or if someone who has a working version, can upload the apk here for others to sideload and test.
