Samsung Galaxy Watch4 and Galaxy Watch4 Classic owners have reached the end of regular software support. The August 2026 security update was reported as the final release for both models, and Samsung’s current wearable security update list no longer includes them.
Your watch will not stop working because support has ended. Core features should continue to work, but owners should not expect future security patches, new Wear OS features, routine bug fixes, or compatibility updates.
That matters if you plan to keep the watch for several more years. It also matters if you are considering buying a used or refurbished Galaxy Watch4. The real question is simple: Is the Watch4 still good enough for your needs, or does a newer Samsung Galaxy Watch make more sense?
As technology experts with over 20 years of experience in hardware and application research and development, we look at products through performance, durability, reliability, and value for money. Our goal is to help readers choose the right product for their needs, whether the priority is budget, performance, reliability, or long-term use.
This article is aimed at Galaxy Watch4 owners, Galaxy Watch4 Classic owners, used-watch buyers, and shoppers deciding whether to keep an older Samsung smartwatch or upgrade. Our recommendations are based on product research, component analysis, real-world usability, and industry experience.
This article uses Samsung’s published support information and independent reporting. It is not a hands-on review, and we have not tested a specific retail unit for this article.
Quick answer: did Samsung stop updating the Galaxy Watch4?
Yes. Regular software and security support for the Galaxy Watch4 and Galaxy Watch4 Classic has ended. By
September 2026, Samsung’s current Mobile Security page no longer listed either model in its wearable security-update scope. Independent reports identify the August 2026 security patch as the final update. Samsung’s official firmware record confirms the Galaxy Watch4 received the August 25, 2026 update with the August 5, 2026 security patch level.
The watches may remain usable for everyday functions such as showing the time, tracking some activities, receiving notifications, and running compatible apps. However, software support is no longer continuing in the normal cycle.
| Model | Launch Generation | Final Reported Update | Current Status |
|---|---|---|---|
| Samsung Galaxy Watch4 | 2021 | August 2026 security update | No longer listed within Samsung’s current wearable support scope. |
| Samsung Galaxy Watch4 Classic | 2021 | August 2026 security update | No longer listed within Samsung’s current wearable support scope. |
Important: Update availability can vary by country, carrier, and model. The table describes the reported support position as of September 2026 rather than promising identical rollout timing in every market.
What was the last Galaxy Watch4 update?
The August 2026 security patch was the final reported update for the Galaxy Watch4 series. The update was
mainly about security fixes rather than a major new hardware capability. Samsung’s support page now lists newer Galaxy Watch models for quarterly wearable security updates, while the Galaxy Watch4 models are absent.
Samsung’s support position became clear in September 2026, when its current wearable security-update scope no longer included the Galaxy Watch4 or Galaxy Watch4 Classic. Independent technology reports therefore described September as the point when support ended, even though the final reported update arrived in August.
For buyers and existing owners, the distinction matters. A final patch is not the same as a watch becoming unusable on the next day. It means the device has reached the end of its expected update path.
Will the Galaxy Watch4 stop working?
No immediate shutdown has been announced. The Galaxy Watch4 should not suddenly stop working solely because software support has ended. Existing functions can continue as long as the hardware, paired phone, apps, and connected services remain compatible.
The practical limitations are:
- No guaranteed security patches: Newly discovered vulnerabilities may not receive a Galaxy Watch4-specific fix.
- Compatibility may become less predictable: Changes to phones, apps, payment services, or cloud services may eventually affect older watches.
- Troubleshooting may become harder: A problem caused by a newer phone or app may not receive a watch-side software fix.
- Battery age remains a separate issue: A four- or five-year-old battery can affect practical value even when the watch still turns on.
These points do not mean every Galaxy Watch4 owner must replace the device immediately. The right decision depends on how the watch is used and how important current security and service compatibility are.
Is the Galaxy Watch4 still safe to use?
The safest answer is qualified: it can still be used, but it no longer has the protection of an active update cycle. The Galaxy Watch4 security update situation is therefore different from a simple feature comparison.
For low-risk uses, an owner may decide that continued use is acceptable. For example, a person who mainly uses the watch as a timepiece, notification screen, or basic activity tracker may not need every new platform feature.
More caution is appropriate when the watch is used for services that handle sensitive information or depend on continuing compatibility. These may include mobile payments, LTE services, account authentication, health-related apps, and frequent interaction with a newer Android phone. The exact impact depends on the service and region, so it would be inaccurate to claim that all such functions will fail.
A practical rule is simple: if the watch is used for security-sensitive services or must work reliably with new phones for several more years, upgrading deserves serious consideration.
How many Wear OS updates did the Galaxy Watch4 receive?
Samsung announced that the Galaxy Watch4 and Watch4 Classic were eligible for up to four years of One UI Watch and Wear OS upgrades. Independent coverage reports the major platform progression as follows:
| Platform Generation | What It Means for Owners |
|---|---|
| Wear OS 3.5 / One UI Watch 4.5 | The first major refinement following the Galaxy Watch4 series’ original Wear OS-based software, bringing interface and usability improvements. |
| Wear OS 4 / One UI 5 Watch | A later platform generation introducing additional system, interface, and smartwatch feature updates. |
| Wear OS 5 / One UI 6 Watch | Continued the Watch4’s software lifecycle with further platform improvements and feature updates. |
| Wear OS 6 / One UI 8 Watch | The latest major platform generation reported for the Galaxy Watch4 series, extending the usefulness of Samsung’s older Wear OS smartwatch hardware. |
A Wear OS upgrade changes the underlying smartwatch platform and can add features or improve compatibility. A security update focuses on vulnerabilities and does not necessarily change the interface or add visible functions. Samsung’s four-year commitment concerned One UI Watch and Wear OS upgrades, while the security-update cycle is a separate support question.
Why the Galaxy Watch4 still matters
The Galaxy Watch4 series was an important transition for Samsung. It moved the company’s mainstream Galaxy Watch line away from its Tizen-based platform and toward Wear OS Powered by Samsung, developed with Google.
That change gave the watches access to the broader Wear OS ecosystem while preserving Samsung’s One UI Watch design approach. It also made the series a reference point for later Samsung wearables.
Its historical importance does not remove the practical limitation of age. A watch can receive the promised platform upgrades and still reach the end of security support later. Owners should therefore judge a used or discounted Galaxy Watch4 by its remaining service life, battery condition, software status, and price rather than by its original launch reputation.
Galaxy Watch4 vs Galaxy Watch4 Classic: which model is affected?
Both models have the same support outcome. The key difference between them is physical design rather than update eligibility.
| Consideration | Galaxy Watch4 | Galaxy Watch4 Classic |
|---|---|---|
| Software Support Status | Ended | Ended |
| Final Reported Security Update | August 2026 | August 2026 |
| Main Design Distinction | More understated and streamlined case design | Classic watch styling with a physical rotating bezel |
| Reason to Choose One Today | Potentially lower used price, provided the watch and battery are in good condition | Best suited to buyers who specifically prefer the physical rotating bezel, provided the watch is in good condition |
| Main Ownership Concern in 2026 | Aging hardware, potential battery degradation, and no future security patches | Aging hardware, potential battery degradation, and no future security patches |
A rotating bezel or preferred case design can still influence comfort and usability. It should not be confused with longer software support. Both models have reached the same support boundary.
Galaxy Watch4 vs newer Samsung watches
Samsung’s current Mobile Security page lists the Galaxy Watch5, Galaxy Watch5 Pro, Galaxy Watch6, Galaxy Watch7, Galaxy Watch FE, Galaxy Watch8, Galaxy Watch9, and Ultra families among current quarterly-supported wearables as of the research date.
| Buying Option | Main Advantage | Limitation to Consider | Suitable For |
|---|---|---|---|
| Used Galaxy Watch4 | Lower initial cost with the familiar Samsung Galaxy Watch experience. | No normal future security or feature updates, combined with aging hardware and potentially reduced battery health. | Buyers comfortable with basic or short-term use. |
| Galaxy Watch5 | Newer hardware than the Watch4 and a later position in Samsung’s support lifecycle. | It is still an older-generation Galaxy Watch compared with Samsung’s latest models. | Buyers looking for a more affordable newer Samsung watch. |
| Galaxy Watch5 Pro | Larger, endurance-focused design with a bigger battery and newer hardware than the Watch4 generation. | Its larger case may feel bulky on smaller wrists. | Buyers who prioritize battery endurance and a larger watch design. |
| Galaxy Watch6 or Newer | Newer hardware and a later position in Samsung’s software support cycle. | Typically costs more than purchasing a used Galaxy Watch4. | Buyers planning to keep their smartwatch for several years. |
| Galaxy Watch FE | Provides a newer entry point into Samsung’s Galaxy Watch ecosystem. | Hardware and feature differences should be compared carefully with other Galaxy Watch models before purchasing. | Buyers prioritizing a lower-cost entry into a newer Galaxy Watch generation. |
This is a support-position comparison, not a laboratory performance ranking. Battery life, sensor behavior, charging speed, display visibility, and app support can vary by model and configuration.
Should you still buy a Galaxy Watch4?
For most buyers seeking a smartwatch for several years of ownership, a new or refurbished Galaxy Watch4 only makes sense at the right price. The device can still make sense in limited cases, but its low price should compensate for its support status and aging battery.
A Galaxy Watch4 may be reasonable when:
- The purchase price is substantially below current supported models.
- The watch is intended mainly for basic notifications, timekeeping, and simple activity tracking.
- The seller provides a clear return policy and accurately describes battery condition.
- The buyer accepts that future software and service compatibility are uncertain.
- The exact model, connectivity version, region, and phone compatibility have been checked.
A newer Samsung watch is the safer choice when:
- The watch will be used for payments, LTE, authentication, or other sensitive services.
- The buyer expects several years of security updates.
- The watch must pair with newer Samsung phones over a longer period.
- Battery longevity and current app compatibility matter more than the lowest purchase price.
- The price difference between the used Galaxy Watch4 and a supported model is small.
The most important buying calculation is not the original retail price. It is the total cost of ownership: purchase price, likely battery replacement, possible service limitations, and how soon another replacement may be needed.
What to check before buying a used Galaxy Watch4
Before purchasing, check the following details rather than relying only on a low headline price:
- Software version: Confirm that the watch has received the final available update for the seller’s region.
- Battery condition: Ask how long it lasts during the seller’s normal Battery performance varies, so avoid treating an informal estimate as a guarantee.
- Model and connectivity: Confirm whether it is Bluetooth-only or LTE and whether the LTE model is compatible with the intended carrier.
- Account removal: Make sure the previous owner has removed the Samsung and Google accounts and completed any required reset.
- Screen and bezel condition: Check for burn-in, cracks, touch problems, and inconsistent bezel operation.
- Charging accessories: Confirm that the correct charger is included or budget for a compatible replacement.
- Return protection: Prefer a retailer or marketplace with a meaningful return window.
- Phone compatibility: Check the required Galaxy Wearable app, Android version, and regional restrictions before paying.
These checks cannot restore future software support, but they reduce the chance of buying a damaged or incompatible unit.

Frequently asked questions about Galaxy Watch4 updates
When did Galaxy Watch4 support end?
Samsung’s current support page no longer lists the Galaxy Watch4 or Galaxy Watch4 Classic. The August 2026 security update is reported as the final update, with the support-list change becoming visible after the September 2026 security bulletin.
Does Galaxy Watch4 Classic still receive updates?
No regular future updates are expected for the Galaxy Watch4 Classic. It reached the same support endpoint as the standard Galaxy Watch4.
What was the final Galaxy Watch4 security patch?
The final reported patch was the August 2026 security update. Rollout timing can vary by market, carrier, and model.
Can Galaxy Watch4 still connect to a phone?
It may continue to connect while the required phone software, Galaxy Wearable app, and related services remain compatible. Because support has ended, future phone or app changes cannot be assumed to work indefinitely with the watch.
Will Samsung repair a Galaxy Watch4?
Repair availability, parts, warranty coverage, and regional service policies are separate from software support.
Check Samsung’s local service information before assuming that a repair or battery replacement is available.
What is the oldest Samsung watch currently supported?
As of the last check, Samsung’s current wearable security list begins with the Galaxy Watch5 and Galaxy Watch5 Pro among the older listed models. The list can change as support periods expire.
Is the Galaxy Watch5 a better buy than the Galaxy Watch4?
For buyers who value a current support position, the Galaxy Watch5 is the more practical choice. The Galaxy Watch4 may cost less, but its lack of future security and feature updates should be reflected in that price.
Should existing owners upgrade immediately?
Not necessarily. Owners can evaluate their usage, battery condition, security needs, and phone compatibility. Immediate replacement is more justified when the watch supports payments, LTE, authentication, or other services that must remain reliable over the next several years.
Where to check current prices
Prices and stock change frequently, especially for refurbished and discontinued wearables. Check the model, condition, return policy, warranty, and regional compatibility before ordering.
Amazon US
The Galaxy Watch4 can still be considered when the price is low and the intended use is basic. Check the latest Amazon US price, seller rating, warranty, and return terms before buying: Amazon US Galaxy Watch listings
Amazon India
Indian buyers should verify LTE-band compatibility, warranty coverage, charger condition, and whether the seller is authorized or offers a dependable return policy. Check the latest Amazon India listings and current offers before buying: Amazon India Galaxy Watch listings
For a longer ownership period, compare the final Galaxy Watch4 price with a supported Galaxy Watch5 or newer model. If the difference is modest, the newer device may provide better value because it starts with a more current support position.
Final verdict
The Galaxy Watch4 and Galaxy Watch4 Classic have reached the end of regular Samsung software support. Their August 2026 security update was the final reported release, but the watches are not expected to stop functioning immediately.
A current owner can continue using the watch for ordinary tasks while accepting the loss of future patches and feature updates. A new buyer should be more selective. The Galaxy Watch4 is only a sensible purchase when its price is clearly low, its battery and condition are verified, and the buyer accepts a shorter and less predictable ownership runway.
For buyers who want a Samsung smartwatch for several more years, a Galaxy Watch5, Galaxy Watch5 Pro, or newer model listed on Samsung’s current support page is the safer choice. The final decision should be based on support status, battery condition, compatibility, and total cost rather than on the Galaxy Watch4’s original launch status alone.
