The Samsung Galaxy S23 Ultra (Ex-UK) costs from KSh 75,000 in Kenya at Galaxy Brandstore today, for the 12GB/256GB version. Samsung no longer makes the S23 Ultra, so the units we sell are Ex-UK phones: used, inspected in our shop, and sold with a 12-month shop warranty (not a Samsung warranty). It is still one of the best-value ways to get a 200MP camera and a built-in S Pen.

What Ex-UK means at Galaxy Brandstore
Ex-UK phones are used phones first sold in the United Kingdom. Before we sell one, we check:
- The screen, touch, cameras, speakers, microphones, buttons and S Pen.
- Battery health and charging.
- That the phone is not locked to an account and the IMEI is clean.
Every Ex-UK phone comes with a 12-month warranty from our shop. It is not a Samsung warranty, and cosmetic marks may be present. Ask us on WhatsApp for photos of the exact unit before you buy.
Why the S23 Ultra is still worth buying
A 200MP camera with 10x zoom
The S23 Ultra has a 200MP main camera, a 12MP ultra-wide, a 10MP 3x telephoto and a 10MP 10x telephoto. Its 10x optical zoom is something even newer Ultras dropped, which makes it great for wildlife, sport and events.
Snapdragon power
The Snapdragon 8 Gen 2 for Galaxy is still fast in 2026, handling games, video and multitasking with ease.
S Pen and a big screen
The 6.8-inch QHD+ screen runs at 120Hz, and the S Pen lives inside the phone for notes and signatures.
Battery
The 5,000mAh battery supports 45W wired and wireless charging. We check battery health on every unit before sale.

Software updates: what to expect
The S23 Ultra launched in February 2023 with Android 13. Samsung promised four OS upgrades and five years of security updates, so it gets security patches until about 2028. That is shorter than a new phone, so factor it in if you plan to keep the phone for many years.
