Hi, great that your doing this to help people including myself out!
Have you recorded these already, or are you still going? Because the 480p resolution makes it really hard to see what's going on in the video, not to mind the fact that it's letterboxed on all 4 sides so it doesn't even fill the whole screen.
It's pretty unpleasant to watch in this state, but I understand you obviously can't change it now without rerecording if you've already done the whole series. Just would be something to keep in mind for any future videos you might make for this series. (If you are going to)
But overall I really like the content. A video suggestion wouldbe could you focus on adding Android source folders to github (like for example packages/apps/Settings ) and creating a repo manifest so someone could use this to make their own ROM, and then allow others to build it like LineageOS has? And maybe how to merge in security patches and even new versions of Android, but that might be too extensive of a topic.
