The Samsung Galaxy S6 - SM-G920F - “zerofltexx” was more exposed to bugs in the near past than the Samsung Galaxy S6 Edge - “zeroltexx” - SM-G925F. Now the S6 Edge was also discovered by the “bug devil”. My short /e/ OS experiences with the SM-G925F here and here.
With other custom ROMs like from Resurrection-Remix-OS-Pie or LineageOS-10 / 17.1 or EvolutionX 10.0 I made good experiences so far. But I’m missing a /e/ OS 9-Pie buildfor this optically very well designed done Samsung Galaxy S6 Edge.
