Oh man, I'm still using my 4a and am quite afraid of what I'll do once it goes caput. There's essentially no real replacement. The S23/24 are kinda okay, but the custom ROM support is meh. Pixels are unbeatable in that regard... It's a shame

I went for an 8a in a compromise of weight and size Vs an-actually-modern-phone.

After 2 weeks I was completely comfortable with it.
