Smart TVs lack a universal software support standard, with update lifecycles varying widely across manufacturers and operating systems like Tizen, webOS, Google TV, and Roku TV.
Review how brands such as Samsung, LG, Sony, and TCL structure their security and software update commitments.
The problem is that there is no common rule for how long each manufacturer will support your TV. Each company follows its own policy, which often varies depending on the model.
How long does support last per manufacturer?
Samsung is offering seven years of software updates for its Tizen-powered models from 2024 onwards, as well as for select 2023 models.
LG has a program that guarantees four years of updates for TVs from 2022 onwards, with a one-year delay compared to the latest software versions of newer models.
Sony doesn't offer a fixed support timeframe. End dates vary by device and model, with its post-2021 models using Google TV and older Android TVs.
TCL also doesn't guarantee a consistent support time and uses different systems, such as Google TV, Android TV, or Roku TV. The company states on its security page that it typically provides security updates for at least two years after the initial shipment.
Support can also vary by region. In Europe, most Hisense TVs use the VIDAA OS, with the company committing to up to eight years of support for models from 2025 onwards. In the United States, they often run other systems, such as Android TV, Fire TV, Google TV or Roku TV.
Roku doesn't set a fixed support window for its Pro, Plus, or Select TVs released in 2023 or later. Vizio regularly sends out automatic updates for its system, but doesn't guarantee a fixed support period. Finally, Insignia TVs use Amazon's Fire OS software, which is committed to security support for at least four years.
What can you do if support ends?
If your TV stops receiving updates, an inexpensive external streaming device is an easy way to extend its life and continue using it normally.
