How long will it last?

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.
29% above the under-$300 median ($6.74/mo, dying phones excluded)
Our verdict
At ~$175 used with security updates to February 2028, the compact S23 works out to roughly $9 per month of safe use — honest value, but only if you genuinely plan to upgrade again in under two years.
Pros
- Still on Samsung's monthly security patch list as of mid-2026
- One more major upgrade coming — Android 17 (One UI 9) in late 2026
- Snapdragon 8 Gen 2 runs cool and fast, a real fix over the 8 Gen 1
- Compact 6.1-inch flagship — increasingly rare
- ~$9 per month of remaining safe use is fair for a used flagship
Cons
- Only ~20 months of security updates left — support ends February 2028
- The buy-by date (February 2026) has already passed for keep-it-long buyers
- 3,900mAh battery was mediocre new; used units will be worse

Frequently asked questions
Is the Galaxy S23 still supported in 2026?
Yes — fully. As of June 2026 the Galaxy S23 still receives monthly security patches, runs One UI 8.5, and has its fourth and final OS upgrade (Android 17 / One UI 9) still ahead of it. Security updates continue until around February 2028 under Samsung's 4-OS/5-year policy.
Should I buy a used Galaxy S23 in 2026?
It's a reasonable short-horizon buy. At roughly $175 used with about 20 months of support left, you pay around $9 per month of safe use. That's fair value — but only if you'll upgrade by early 2028. As a keep-it-forever phone, it fails: the two-years-of-runway buy-by date passed in February 2026.
When does Galaxy S23 support end?
Around February 17, 2028 — five years after its February 2023 US release. The S23 generation got 4 OS upgrades plus 5 years of security updates; Samsung's 7-year window only began with the Galaxy S24.
Will the Galaxy S23 get Android 17?
Yes. Android 17 (One UI 9) is confirmed as the S23 series' fourth and final major OS upgrade, expected in late 2026 after Samsung's beta program. After that, the phone gets security-only patches until support ends in February 2028.
