Because its a very cute phone
The Samsung Galaxy Alpha SM-G850F Codename “slte” aka “sltexx” with its metal frame and exchangeable battery is a compact smartphone with 4.7" inch HD Super AMOLED screen with 1,280 x 720 pixels, chipset Exynos 5430 Octa; released 2014, September, last StockROM Android 5.0.2 (Lollipop).
Officially the device “slte” was never supported by LineageOS. I could only find older UNOFFICIAL CyanogenMod 12.1 and 13.0 and LineageOS 14.1 builds. In my estimation the chances for a /e/ OS relaunch should be extremely small.
Yea you are probably right but still its a nice phone (although battery life is poor), I want to update it but i cant find a good custom rom.
