Cellphone is something too much personal so I prefer a new device, cause I’ll be having it for its whole lifespan. I went for S23 8/256 on 6 of February and no regrets cause I’ll be having it for whole 5y. But I got it for 600$, I wouldn’t pay the full price.
I had only one phone from second hand and it was xperia compact z1. It wasn’t bad deal, but it was already 2y old, but for the price it was ridiculous deal. It lasted 2 years and I had to upgrade to new device, newly bought this time.
I assume if I had to I’d not mind buying second hand again but only max 1y old (since premiere) device, from reputable reseller and it would have to be flagship only.
