In 2026, Samsung Electronics is carrying out one of its largest smartphone portfolio revisions in recent years. Under the company’s current update policy, a significant number of popular Galaxy models are reaching End of Life (EOL) status. This means the end of regular security patches and official software maintenance.
For users in the US and Canada, this is not an abstract concept. A phone does not stop working once support ends, but over time it becomes less secure and increasingly incompatible with modern apps and services. That is why 2026 marks a turning point for owners of several Galaxy generations.
Samsung’s Update Policy: What Changes in 2026
To properly understand the situation, it is important to distinguish between two types of updates. The first includes major Android and One UI version upgrades. The second consists of regular security patches that fix vulnerabilities and maintain system stability.
Until 2024, Samsung followed a “4+5” model for flagship devices: four years of Android updates and five years of security patches. Starting with the Galaxy S24 series, Samsung shifted to a seven-year full support cycle. However, this policy does not apply to devices released in 2021 or earlier. As a result, many Galaxy models reach the end of their supported lifespan in 2026.

Samsung Phones That Lose or Are Losing Support in 2026
Galaxy S and Z Flagship Models
The most notable change affects the Galaxy S21 lineup. These devices remain widely used in North America, especially on the secondary market and through carrier trade-in programs.
Galaxy S21, Galaxy S21+, and Galaxy S21 Ultra have officially completed their regular security update cycle. The last stable software version for these devices is based on Android 15.
Galaxy Z Fold3 and Galaxy Z Flip3, Samsung’s first widely adopted foldable smartphones, also reach the end of their update support by mid-2026.
Galaxy S21 FE technically remains on the support list, but has been moved to a critical update schedule with extended intervals. Historically, this signals full end of support within the following year.
Midrange and Budget Galaxy A and M Series
Midrange and entry-level devices have always followed shorter support cycles, which significantly expands the list of unsupported models in 2026.
Galaxy A52s 5G, one of Samsung’s most popular midrange phones, no longer receives even minor security updates.
Galaxy A13, A22, and A32 — budget models released between 2021 and 2022 — have also exited Samsung’s update program.
Galaxy M32 and Galaxy M52 5G, known for large batteries and online-focused sales, have likewise entered EOL status.
What End of Support Means for US and Canadian Users
Lack of updates does not cause immediate device failure, but it has practical consequences. Without regular security patches, smartphones become more vulnerable to newly discovered exploits. This is especially important for users who rely on mobile banking, payment apps, corporate email, and two-factor authentication.
Compatibility issues also increase over time. New versions of One UI and Galaxy AI features are designed for modern chipsets and are not optimized for older processors. As a result, even official apps may run slower or lose functionality.
Another important factor is resale value. In 2026, prices for used Galaxy S21 devices on marketplaces such as eBay and Swappa decline noticeably due to the lack of future software support.
When It Makes Sense to Upgrade in 2026
If your device is already on the unsupported list, upgrading becomes a practical consideration. A phone may continue to function for another year or two, but risks related to data security and app stability increase steadily.
Samsung devices released after 2024 are designed for long-term use. They receive regular security patches, Android upgrades, and One UI updates for several years. This allows users to rely on their devices without constantly planning a replacement.
At this point, it makes sense to look at current flagship or upper-midrange Samsung models with a predictable support timeline. A link to a newer device can be placed here without disrupting the overall structure of the article.
Samsung Phones That Will Remain Supported Beyond 2026

| Galaxy S25 / S25 Ultra | 2025 | Android 22 (expected) | 2032 | 7 years (full) |
| Galaxy S24 / S24 Ultra | 2024 | Android 21 (expected) | 2031 | 7 years (full) |

| Galaxy S23 / S23 Ultra | 2023 | Android 17 | 2028 | 4 years Android / 5 years security |
| Galaxy A55 / A35 | 2024 | Android 18 | 2029 | 4 years Android / 5 years security |
| Galaxy A54 / A34 | 2023 | Android 17 | 2028 | 4 years Android / 5 years security |
| Galaxy S21 FE | 2022 | Android 16 | 2027 | 4 years Android / 5 years security |
Why Smartphone Updates Matter Beyond New Features
Many users associate updates with new features or visual changes. In reality, this is only the surface. The primary role of regular Android and One UI updates is maintaining security and long-term system reliability.
Security patches address vulnerabilities discovered in the operating system, drivers, and network components. Without these fixes, smartphones become more exposed to malware, phishing attacks, and data leaks. This is particularly relevant for users who rely on mobile payments, password managers, and work-related accounts.
Updates also ensure compatibility. Banking apps, messaging platforms, authentication services, and web browsers gradually stop supporting older Android versions. As a result, an unsupported device may continue to function, but essential apps can become unstable or stop working altogether.
System optimizations are another factor. Even without new features, updates often include performance improvements, better battery management, and fixes for Bluetooth, Wi-Fi, and GPS stability. Without them, a device may feel slower and less reliable under modern workloads.
That is why end of support is not just about missing features. It represents a gradual loss of security, compatibility, and predictable day-to-day performance.
