Galaxy S10 for everyday users

The Samsung Galaxy S10 is an unlocked 4G smartphone with 128 GB of storage in Prism Black. Its 6.1 inch Dynamic AMOLED display supports HDR10+ for vivid colour and contrast. The glass front uses Gorilla Glass 6 while the back uses Gorilla Glass 5, both set in an aluminium frame. A single Nano-SIM slot keeps connectivity simple for personal or work use.

Sustained performance and thermals

The Snapdragon 855 or Exynos 9820 processor paired with 8 GB of RAM handles multitasking and demanding apps without rapid throttling. A 3 400 mAh battery supports a full day of mixed use and includes fast wireless charging plus reverse wireless charging for accessories. The ultrasonic in-display fingerprint sensor remains responsive during extended sessions. IP68 water resistance adds durability for daily exposure.

Build quality and daily practicality

At 149.9 x 70.4 x 7.8 mm and 157 g the handset fits comfortably in one hand. Grade B condition means the body may show dents, chips or scuffs and the screen may have hairline scratches. The glass sandwich construction feels premium but benefits from a case to prevent further cosmetic wear. The hybrid SIM tray offers either a second Nano-SIM or a microSD card up to 512 GB for extra storage. Not suited for buyers who need dual physical SIMs and expanded storage simultaneously or who require 5G connectivity.

Questions about this item

How much heat does the Snapdragon 855 generate during all-day use?

The Snapdragon 855 and Exynos 9820 are built on a 7 nm process for efficiency. The 3400 mAh battery supports full-day runtime, and the 7.8 mm glass-and-aluminium body dissipates heat without active cooling.

What size nano-SIM do I need for the single-SIM tray?

The tray accepts a standard nano-SIM (4FF). No adapter is required, and the phone is fully unlocked for any 4G carrier.

Will my existing microSD card work in the hybrid slot?

Yes, the hybrid tray supports microSD cards up to 512 GB alongside the nano-SIM, so you can keep using your current card for extra storage.
