A smart TV with reliable long-term support is one whose manufacturer clearly separates security updates from feature updates and states how long each lasts. Among the current manufacturer policies cited here, eligible Samsung TVs launched from 2023 have the clearest longest commitment—up to seven years of One UI Tizen upgrades and seven years of security updates—while LG’s cited webOS25 statement promises five years of security updates. That still may be shorter than the seven-to-ten-year period many households keep a television, so the safest purchase combines a documented support window with a replaceable external streaming device.
Use the guide below to verify the exact model, calculate its remaining support, and plan what happens when the built-in software ages.
At a glance
| Name | Best for | Key support evidence | Checked |
|---|---|---|---|
| Samsung eligible TVs launched from 2023 | Buyers prioritising the longest published manufacturer commitment | Up to seven years of One UI Tizen upgrades; seven years of security updates from initial launch, subject to model and region | November 2026 |
| Other Samsung smart TVs | Samsung buyers choosing a model outside the seven-year eligibility | Samsung says five years of security updates for other smart TVs; feature support varies | November 2026 |
| LG webOS25 product class | Buyers wanting a stated security period on a current LG platform | Five years of security updates from the webOS25 launch date; cited product supported until 31 December 2029 | November 2026 |
| Amazon Fire TV models | Households planning to use a replaceable Fire TV platform | Which? reports at least four years of support; verify the exact model and region | November 2026 |
| Hisense or Sony models covered by Which?’s comparison | Buyers comparing mainstream alternatives | Which? lists four years; confirm the model-specific policy before purchase | November 2026 |
| Panasonic models covered by Which?’s comparison | Buyers considering a shorter published window | Which? lists three years; verify the exact model | November 2026 |
| Philips models | Only if the seller supplies a written model-specific policy | Which? reports no typical published support policy | November 2026 |
These are policy summaries, not guarantees for every television sold under a brand. Eligibility, launch date, country and hardware can change the result.

It includes at least two different promises. Security updates fix vulnerabilities and help keep a connected television safer. Functionality or operating-system updates add features, change the interface, update built-in apps and sometimes alter compatibility. A manufacturer can continue security patches after feature development has slowed, so one headline number is not enough.

Ofcom says most television-selection-service providers offer functionality updates for only one or two years from market launch and security updates for around five years. It also warns that hardware limits or commercial decisions can prevent an older platform from receiving updates, and that content services may stop working with old platform versions. That explains why a TV can still display an input perfectly while its built-in streaming apps become unreliable.
The support clock matters as much as its length. A promise may run from the model’s launch, the product launch year, the first sale in a region, or another date. A television discounted two years after launch can therefore have less remaining support than a newer model with a similar retail price.
Which manufacturers publish the clearest support commitments?
Based on the cited manufacturer documents and the comparison published by Which?, Samsung has the strongest clearly stated commitment for eligible recent models. LG provides a concrete five-year security statement for the referenced webOS25 product class. Other brands have shorter or less consistently published periods, so model-level confirmation is essential.
| Brand or platform | Security-update evidence | Feature or OS-update evidence | Important qualifications |
|---|---|---|---|
| Samsung, eligible TVs launched from January 2023 | Samsung’s security page says seven years from the product’s initial launch. | Samsung UK says eligible TVs released from 2023 receive free One UI Tizen upgrades for up to seven years from the product launch year. A 2024 TV is described as supported through 2030. | Availability varies by model, region and hardware; delivery timing can vary. |
| Samsung, other smart TVs | Samsung says other smart TVs are guaranteed security updates for five years. | No single seven-year feature promise applies to every older or excluded model. | Check the exact model family and regional page. |
| LG webOS25 product class | LG’s UK PSTI statement says the security-update period is five years from the webOS25 launch date. | The document is a security commitment, not a guarantee that every future webOS feature will arrive on every model. | The referenced product is stated to be supported until 31 December 2029; scope is tied to that product class and market. |
| Amazon Fire TV | Which? lists at least four years for Amazon Fire TVs. | Feature availability can vary by device and software version. | Confirm the exact television or streaming-stick model and region. |
| Hisense and Sony models in Which?’s comparison | Which? lists four years. | Model-specific feature promises are not supplied in the comparison. | Use the manufacturer’s policy for the exact model before paying. |
| Panasonic models in Which?’s comparison | Which? lists three years. | Model-specific feature promises are not supplied in the comparison. | Confirm the launch date and support end date. |
| Philips models in Which?’s comparison | Which? reports no typical published support policy. | No general feature-update period is established by the cited comparison. | Ask the seller or manufacturer for written, model-specific terms. |
Read Samsung’s security-update policy and One UI Tizen support page together: one covers security, while the other describes the broader upgrade programme. For LG, the webOS25 compliance statement is the relevant evidence for the cited five-year security period.
How do I check the support period for an exact TV model?
Do this before relying on a retailer’s “latest” or “future-proof” wording. The product family, country and launch date can all change the answer.
- Copy the complete model code. Record the suffix, screen size and regional version, not just the marketing name. Similar names can cover different hardware and policies.
- Find the manufacturer’s support or security page. Search for the model code plus “security updates,” “software support” or “PSTI statement.” Prefer a dated manufacturer document over a retailer summary.
- Identify the support start point. Write down whether the clock starts at initial launch, launch year, first sale or another stated event.
- Record security and feature periods separately. For example, “security: seven years from launch; feature: up to seven years, model-dependent” is more useful than simply writing “seven years.”
- Check region and hardware exclusions. A policy page may cover one country, selected model families or only hardware capable of running the newer operating system.
- Calculate the remaining window. Subtract the current date from the published end date. A new-looking clearance unit may already have consumed part of its support period.
- Save the evidence. Keep a PDF, screenshot or link with the model code and date checked. Policies can be revised, and this record helps with future troubleshooting or a warranty conversation.
If no policy can be found, treat the support duration as unknown rather than assuming the brand’s newest headline applies to the television in your cart.

How should I compare security updates with feature updates?
Use two columns in your buying notes and make a decision only after both are filled. Security support protects the connected device; feature support determines how long the built-in platform is likely to keep evolving and accepting current services.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitches| Question | Why it matters | What to write down |
|---|---|---|
| How long are security updates promised? | Shows the stated period for vulnerability fixes. | Years, end date and the event that starts the clock. |
| How long are OS or functionality updates promised? | Indicates how long new interface features, app changes or platform improvements are expected. | Years, “up to” wording and any model exclusions. |
| Are updates automatic, manual or both? | A supported TV can still miss fixes if updates are disabled or never installed. | The manufacturer’s update instructions and the setting you will use. |
| What happens after feature support ends? | Some apps may continue for a while; others can require a newer platform version. | Your fallback device and the services it supports. |
Be cautious with “up to” language. It describes a maximum programme, not a promise that every model receives every feature for the full period. Samsung explicitly notes variation by model, region and hardware, and LG’s cited statement is specifically about security updates.
Will streaming apps still work after the TV stops receiving updates?
They may, but there is no dependable universal grace period. Ofcom notes that content services can become incompatible with old platform versions, even when the television itself still operates. App developers can also change requirements independently of the panel manufacturer.
List the services your household actually uses—such as live-TV catch-up, subscription video, music or fitness apps—and check whether each is available on the TV’s current platform. Do not assume that an app present on the box will remain supported for the entire ownership period.
Use a replaceable streaming device as a longevity plan
A streaming stick or set-top box moves the app layer to separate hardware. When the television’s built-in software becomes outdated, you can replace the small external device without replacing the panel. Ofcom treats these devices as television-selection-service platforms too, so they have their own hardware and support limits.
Which? reports at least four years of support for Amazon Fire TVs. An Amazon Fire TV streaming stick can therefore be a practical fallback, but verify the exact model, country and current support terms before buying. The accessory does not extend the TV manufacturer’s security period; it simply provides a newer platform for apps.

- Confirm that the stick or box supports the services and video formats your household needs.
- Read its own security and software-support policy, including when its clock starts.
- Keep the TV’s built-in software updated for as long as it remains supported, even if you mainly use the external device.
Is Samsung or LG better for long-term support?
Samsung is the stronger choice on the cited published duration if you buy an eligible TV launched from 2023 onward: the evidence combines seven years of security updates with up to seven years of One UI Tizen upgrades. LG’s cited webOS25 document gives a clear five-year security period, but it does not promise that every future webOS feature will reach every model.
That does not make every Samsung television a better purchase. An excluded Samsung model may carry the brand’s five-year security guarantee rather than the seven-year programme, and a later LG model could have more remaining support than an older Samsung clearance unit. Compare the exact launch date, regional policy and end date rather than choosing by logo.
How much should support affect the buying decision?
Weight support according to how dependent you are on the built-in platform. If the TV is mainly a display for a game console, disc player or computer, panel quality and inputs may matter more, because an external device can handle streaming. If the television is the household’s only streaming hub, a longer, clearly documented platform window deserves a higher priority.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Use this simple decision rule:
- Choose the longer documented window when two models have similar picture, audio and connectivity characteristics.
- Choose the newer launch when policies are otherwise similar, because more of the published period should remain—but verify the actual policy first.
- Choose a model with a fallback path when the manufacturer publishes little or no support information.
- Do not pay a premium for an unverified promise. A retailer’s “future-ready” label is not a support term.
Ofcom’s seven-to-ten-year average replacement interval shows why this matters: a five-year security period can end while the panel is still perfectly usable. Which?’s survey of 1,051 members in October 2022 found that around nine in ten considered security updates important when buying a smart product, yet about two-thirds did not know how long support would last at purchase.
What privacy and update settings should I review?
Keep updates enabled while the television is within its support period, and review data-sharing choices during setup and after major software changes. Samsung documents both automatic and manual update methods; use the model’s on-screen Software Update controls and check periodically that the last update completed successfully.
Review advertising personalisation, voice-assistant permissions, viewing-data collection and connected-app permissions individually. Turning off optional collection can reduce personalisation or convenience, so record what each setting changes. Privacy controls do not replace security updates, and disabling updates to avoid interface changes can leave a supported television without important fixes.

What happens when the built-in support period ends?
Support ending does not make a TV instantly unusable. It means the manufacturer no longer promises the same flow of security or functionality fixes. Existing inputs, broadcast reception and some apps may continue, but compatibility and security become less predictable.
At that point:
- Move streaming to a currently supported external device.
- Remove unused accounts and apps from the TV.
- Use the television primarily as a display if you no longer trust its connected software.
- Check your home-router controls and isolate an unsupported smart TV from sensitive devices if your network equipment allows it.
- Replace the panel only when its picture, inputs or reliability no longer meet your needs.
An external streamer is a mitigation, not a permanent guarantee. Its own support window will eventually end, so record that device’s model and policy as carefully as you did for the TV.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What should I ask a retailer before paying?
Send these questions to the retailer or manufacturer and keep the answers with your receipt:
- What is the exact regional model code?
- When was this model first launched in this market?
- What date does the security-update clock start?
- What is the published security-update end date?
- How long are operating-system or functionality updates promised?
- Does the policy apply to this screen size, hardware revision and region?
- Which built-in apps are guaranteed, and what happens if they become incompatible?
- Can the TV use an external streaming stick or box as a fallback?
If the seller cannot answer the first five questions, compare another model or budget for an external streaming device from the start.
How we picked the support criteria
The comparison prioritises published security duration, published functionality or operating-system duration, the date that starts each clock, model and regional exclusions, likely app-dependency risk, availability of a replaceable external streaming platform, and the clarity of privacy and update controls. The periods come from manufacturer statements and the cited Which? comparison; they are not independent performance tests.
Bottom line: buy the policy, not just the panel
For the clearest longest commitment in the cited evidence, start with an eligible Samsung TV launched from 2023 onward and verify that the exact regional model qualifies. LG’s webOS25 class is a credible alternative when its five-year security statement fits your needs. Whatever brand you choose, write down separate security and feature end dates, confirm the launch clock, and plan a replaceable streaming device before the built-in apps age.

Frequently Asked Questions
Can I use a smart TV safely after security updates stop?
You can still use it as a display, but an unsupported connected device no longer receives the manufacturer’s promised vulnerability fixes. Move streaming to a supported external device, remove unused accounts and consider isolating the TV from sensitive devices on your home network.
Does a newer TV always have more support left?
Usually a later launch leaves more of a stated support period remaining, but not always. Eligibility, regional versions and the policy’s start date can make an older model’s remaining window longer, so compare published end dates rather than relying on release year alone.
Are smart TV app updates guaranteed for the whole security period?
No. Security updates and app or feature updates are separate promises. A manufacturer can continue security patches while a particular streaming service changes its requirements or stops supporting an older platform.

One-click scans. No signup required.
Should I buy a TV with no published support policy if it is heavily discounted?
Only if you are comfortable treating the built-in software as temporary and using an external streamer. Without a written policy, you cannot reliably calculate the security window or know whether the brand’s general statement applies to that model and region.
Will an external streaming stick make an old TV future-proof?
It can extend app access by moving streaming to newer hardware, but it does not upgrade the television’s firmware, panel or inputs. The stick has its own hardware limits and support period, which must also be checked.
