Dynamic AMOLED display (Full HD+ / Quad-HD+), HDR10+ support — rich colors, deep blacks and great contrast for media and browsing. 

Multiple size options: from compact 5.8″ (S10e) to large 6.4″ (S10+) — caters to different preferences (compact vs. large-screen phones). 

Flagship-class performance (Snapdragon 855 / Exynos 9820, octa-core + ample RAM) — smooth multitasking, good gaming and overall snappy performance. 

Flexible storage + expandable memory (microSD slot up to ~512 GB) — plenty of built-in storage (128GB/256GB/512GB/ even 1TB on some S10+), with room to expand. 

Versatile rear cameras (wide + ultra-wide + (on S10/S10+) telephoto) + capable selfie camera — good photo/video versatility including wide shots, portraits, zoom, and selfies. 

4K UHD video recording (rear & front) + slow-motion / frame-rate flexibility — strong video capabilities for its generation. 

Good battery life + wireless charging + reverse wireless charging (PowerShare) — reasonable battery capacity for daily use, and convenient charging options. 

Premium build + design — curved/glass / metal (flagship feel) — high-end feel in hand, premium materials and finish. 

Still-decent for everyday use in 2025 — many users report they continue using S10 models as daily drivers years later (good longevity, performance remains acceptable). 

Extra features rare in newer phones: microSD support, headphone jack, and flexible configurations — adds flexibility for those who value expandability or legacy accessories.
