Just to check - is the Samsung Galaxy S7 G930F 32GB supported? I am sure I read about an installer (possibly still beta) that can be used from a laptop (I use Linux Mint) to install eOS on your phone. I cannot find reference to it now an any e.foundation webpage!
This is from the full spec of Galaxy S7 G930F;
“The phone is powered by the Exynos 8890 soc with a Quad-Core 2.3 GHz + Quad-Core 1.6 GHz configuration. Memory is 4GB, with the device offering 32GB (UFS2.0) internal storage.”
