I think the Nexus 4 is still my favourite phone I've ever owned. Maybe it represents a period of techno-optimism I had, and how my relationship with phones have changed over the years. Now I despise my phone but am required to own it for my digital ID to pay taxes, receive work messages, etc.
Sounds like I've been very lucky with my Pixel 4 and 7 that I haven't had any hardware issues while running GrapheneOS.
