I haven't ran GrapheneOS in probably 5 years now? In 2010 I got my first Android phone. I wanted the Google Nexus One, but it wasn't available on my carrier. Anyway, my first Android phone was the HTC Droid Incredible. A friens basically told me hey you're a tech geek you should run a custom ROM. And I had no clue what he was talking about. I headed over to xda-developers.com and went full Android nerd. For the next decade I ran ever custom ROM I could find, made my own, ran custom kernels and radios, etc. I started with MIUI, and moved around to CyanogenMod, ParanoidAndroid, AOKP, and several others. I mostly ran CM though. I did try Graphene and Calyx years ago as I mentioned. I don't run a custom OS now because I don't want to dick with my phone all day long. I don't have time. I want it to work when I need it. My phone is my #1 computing device and I need it to just work.
