Okay, thanks. Since I haven’t even seen a homescreen of /e/ OS GSI and since yesterday I know that “If there are changes in the ROM - even minor it is not an /e/ROM it becomes a Custom ROM.” - so I asked myself this question.
I could install /e/ OS GSI on a Galaxy S9 But I feel like @yoda67 right now. At the moment the thought of a GSI first installation attempt on an almost brand new S9 makes me feel uncomfortable.And I still have to answer the questions about the “how to proceed with the /e/ OS GSI ROM”.
Just for fun, install /e/ OS GSI? Maybe once in a reckless hour …
