yeah i got a 4k phone several years ago (1440 x 3040), they have been around a couple years now, 4k is still the top, but now the highest resolution phone is 2160 x 3840 which is still like, 4k, just a higher 4k, slightly bigger pixel numbers

mostly i chose that phone because i wanted my smartphone to last a long time and be future-proofed and have the best specs so i wouldn’t have to upgrade for like, 5 or 6 years not planning on getting a new phone until this one stops working
