I am still happy with the build. It is stable and usable, however, I am not using the device very often now. (Sfos is a bit slow on it and got some other devices to work with and test.) I still build sfos to the S2 but some things do not properly work. I've planned to make waydroid work on it but that would require a lot of work as the port uses a cm12.1 base and the device has a very old kernel (version 3.0). I've started to re-base to los17.1 but unfortunately, that also lacks some stuff that is required for Waydroid. Therefore I've put it aside and probably will come back to it later.
