Precisely, a couple of days ago, in my search for information on this subject, I found a e-ink device, likebook, that a) runs Android and b) has an option to be able to see things on the screen like a normal tablet, that is, that you can watch videos and more. Grayscale, of course, but without the problems of a typical e-ink screen. In yt there are some videos that show this double use. It's interesting. Anyway I don't know if a custom build of Android can be installed on this device. Actually, the idea of a device running Android is interesting because it allows you to install termux and thus Emacs. You could even use Emacs GUI by installing a GNU/Linux distro in termux and loading it as proot (+ vnc), or just activating the X11 repo in termux, but I don't know what the performance would be like. Probably horrible. On the other hand, the only free app to annotate PDFs on Android is pen&pdf (based on muPDF), but it hasn't been maintained for several years. It can be installed on F-droid by adding the IzzyOnDroid repository, but I don't know if installing it would be a security risk... Everything said in this threed is very interesting, but now I am hesitating between buying one of these devices or simply a 10-inch tablet with a good screen, and then applying all possible blue light filters to it. By activating the developer options, you can also turn Android grayscale. Of course it's not the same as an e-ink screen, but maybe I can work it out. Best regards, Juan Manuel
