Samsung promises 5 years of updates for this phone, so it's supported until February 2028 — buying it today still gets you about 1.7 years of safe use.

TrueCost
Street price ÷ months of safe use remaining — the number that makes cheap short-lived phones expensive, and well-supported ones cheap.
34% above the $300–600 median ($12.54/mo, dying phones excluded)
Our verdict
A 200MP camera, 10x periscope and S Pen for ~$339 used is genuinely tempting — but support ends February 2028, so you're paying about $17 per month of safe use for hardware you'll have to retire early.
Pros
- The most complete used camera kit anywhere near this price — 200MP main plus a real 10x periscope
- Built-in S Pen; no other used flagship has one
- 5,000mAh battery, QHD+ LTPO display, and a still-fast Snapdragon 8 Gen 2
- Monthly security patches continue as of mid-2026, with Android 17 still to come
Cons
- ~20 months of security updates left — over in February 2028
- ~$17 per month of remaining safe use — double what a used base S23 costs per month
- Buy-by date passed in February 2026
- 234g brick; used units often have worn batteries under that big screen

Frequently asked questions
Is the Galaxy S23 Ultra still supported in 2026?
Yes. As of June 2026 it still gets monthly security patches, runs One UI 8.5, and has its final OS upgrade — Android 17 (One UI 9) — arriving in late 2026. Security updates run until around February 2028 under Samsung's 4-OS/5-year policy for the S23 generation.
Should I buy a used Galaxy S23 Ultra in 2026?
Only with a clear exit plan. At roughly $339 used and about 20 months of support left, it costs ~$17 per month of safe use — you're paying a premium for the 200MP camera, 10x zoom and S Pen, not for longevity. If you'll happily resell or retire it by early 2028, it's the cheapest way to get this hardware. If not, skip it.
When does Galaxy S23 Ultra support end?
Around February 17, 2028 — five years after its February 17, 2023 US release. It gets 4 OS upgrades (ending with Android 17) plus 5 years of security updates. Samsung's 7-year support era began with the Galaxy S24 series, one generation later.
Is the Galaxy S23 Ultra still worth it for the camera in 2026?
For photography on a budget, yes — its 200MP main sensor and dual telephotos still beat anything else near $339. Just treat it as a ~20-month purchase: support ends February 2028, after which it becomes a great camera attached to an increasingly risky phone.
