I have the Samsung SIII and will install /e/ on it but I also have two more devices that are not listed:
Samsung Galaxy S8 5110
Lenovo Vibe K6
Well, I might as well try to learn how to do it myself! Great goal for 2019… 
I’m also interested in installing in a Samsung S8+
I feel like after two years it’s beginning the programmed obsolescence phase. /E/ is running well on much older devices.
No official LineageOS support for those devices.
