About the Samsung Galaxy S23
The Samsung Galaxy S23 launched in February 2023 as the compact flagship in Samsung's lineup, and in 2026 it stands out as one of the best small Android phones you can still buy. Its 6.1-inch Dynamic AMOLED 2X display packs a 120Hz adaptive refresh rate and 1,750 nits peak brightness into a form factor that sits comfortably in one hand, a rarity in an era of ever-growing screens. The Snapdragon 8 Gen 2 for Galaxy chip remains impressively capable, handling everything from demanding games to 4K video editing without throttling, while its 4nm efficiency keeps battery drain in check. The triple camera setup features a 50MP main sensor, 12MP ultrawide, and 10MP 3x optical zoom telephoto, delivering versatile photography that holds up against current mid-range phones and many flagships. Samsung has committed to four OS updates and five years of security patches: the S23 now runs Android 16 (One UI 8), will receive Android 17 as its final update, and security patches continue through 2028. Gorilla Glass Victus 2, IP68 water resistance, and wireless charging round out a complete package. With prices dropping significantly below the original launch cost, the Galaxy S23 is the rare compact phone that sacrifices nothing in performance, cameras, or build quality.

Frequently Asked Questions
Is the Samsung Galaxy S23 still worth buying in 2026?
Yes, the Samsung Galaxy S23 is an excellent buy in 2026, particularly if you want a compact flagship. The Snapdragon 8 Gen 2 still delivers smooth, responsive performance, the camera system with 3x optical zoom remains versatile, and it will receive Android 17 with security patches through 2028. At current discounted prices, it offers flagship quality at a mid-range cost. The main reason to choose the newer S24 instead would be for the brighter display and Galaxy AI features.
How big is the Samsung Galaxy S23 screen?
The Samsung Galaxy S23 has a 6.1-inch Dynamic AMOLED 2X display, making it one of the most compact flagship phones available. It weighs just 168 grams and is designed for comfortable one-handed use. Despite the smaller screen, it delivers the same 120Hz refresh rate, Full HD+ resolution, and 1,750 nits peak brightness as its larger siblings.
How good is the Samsung Galaxy S23 camera?
The Galaxy S23 camera system punches well above its compact size. The 50MP main sensor with f/1.8 aperture captures detailed, well-exposed photos in most conditions. The 10MP 3x optical zoom telephoto is excellent for portraits and reaching distant subjects, and the 12MP ultrawide covers group shots and landscapes. Night mode produces impressive low-light results across all three lenses.
Does the Samsung Galaxy S23 support wireless charging?
Yes, the Galaxy S23 supports 15W wireless charging and 4.5W reverse wireless charging for topping up Galaxy Buds or other compatible accessories. Wired charging runs at 25W, getting from empty to around 50 percent in about 30 minutes. While not the fastest charging in its class, the efficient Snapdragon 8 Gen 2 means you charge less frequently.
How long will the Samsung Galaxy S23 receive software updates?
Samsung guarantees four years of major Android OS updates and five years of security patches. The Galaxy S23 launched with Android 13 and now runs Android 16 (One UI 8). It will receive Android 17 as its final major update in late 2026 or early 2027, and monthly security patches will continue through 2027 with quarterly patches through 2028.
How does the Samsung Galaxy S23 compare to the Galaxy S24?
The Galaxy S24 upgrades to the Snapdragon 8 Gen 3, a brighter display at 2,600 nits, and adds Galaxy AI features like Circle to Search and Live Translate. It also gains a flatter design with a titanium-like finish. However, the S23 offers very similar camera performance, the same update commitment timeline, and identical IP68 and wireless charging capabilities at a significantly lower price in 2026.
Is the Samsung Galaxy S23 Ultra worth it over the Galaxy S23?
The S23 Ultra's biggest advantage is its camera system: a 200MP main sensor and 10x optical zoom telephoto vastly outperform the S23's 50MP main and 3x zoom. You also get a larger 6.8-inch display, a 5,000mAh battery versus 3,900mAh, the built-in S Pen, and 45W fast charging. The trade-off is size and cost — the S23 starts at £449 SIM-free and is far more pocketable at 6.1 inches. If photography and screen size matter most, the Ultra justifies the premium.
