Post-Purchase Truths

Samsung: What to watch for

Ergonomics
Sharp 90-degree squared corners dig aggressively into palms.
One-handed typing causes the pointed lower corner to dig into your palm tissue unless cushioned by a rounded silicone case.
Hardware Quirk
Anti-reflective Gorilla Armor glass smudges easily with skin oils.
While outdoor glare reduction is class-leading, finger oils create noticeable rainbow sheen smudges in bright sunlight.

OnePlus: What to watch for

Hidden Cost
No wall charging adapter included in the retail box.
Packaging contains only a Type-C cable; high-speed wall charging bricks must be purchased separately if you do not already own one.
