This change has to happen sooner or later because of Android's limitations. Other games do this as well! I don't think a lot of people have problems with it but if they do have problems, it's probably on Android because 1. The installation is more complicated than on PC and 2. On average, Android users are less tech savvy than PC users.
Someone should do a video tutorial on how to install Eternum on Android, I think that'll help a lot.
