Is there an unofficial Graphene OS ROM for S23? Because if there isn’t and you want to try it, the Pixel remains your only choice. Have you had a look at Zenfone (8/9/10)? When my S9 comes to its EOL, one of those will most likely be my choice. (I won’t lie, I prefer to have the 3.5mm jack on my phone!)

Waterproofing requirement means that glue is mandatory even with the presence of a gasket
