Chromecast & Google TV support: keep or replace?

Sources: Google security policy and production firmware. Minimum dates are not final support dates.

Read the dates correctly

The minimums below use Google's US Store start-of-sale basis, not your purchase date or a worldwide launch date. Google's policy table supplies these dates directly. For example, Chromecast with Google TV (4K) is beyond its minimum but still listed for critical updates. This does not guarantee a new fixed support period.

Why older model dates may look different elsewhere

Google's policy table uses 22 October 2018 for third generation, 30 September 2015 for second generation and 31 July 2013 for first generation. Launch announcements or third-party directories may use other dates. We retain the policy's own basis instead of combining unlike milestones. We do not infer an exact last-patch day for first generation.

A documented build is not a live scan

The firmware source displays an update date of 23 June 2026; we checked it on 20 September. Google lists October 2025 security patches for both Google TV Chromecasts and April 2026 for Streamer. These are dated source observations, not readings from your device. Google's production table differs from its preview table; rollout happens in stages.

Identify and update your device

Confirm the full generation from your device information or packaging; HD and 4K are separate entries. In Google Home, open the device tile, then Settings and Device information to inspect firmware. For Google TV system updates, use All settings → System → About → System update. Follow Google's linked instructions if your menus differ.

Keep: when the evidence supports waiting

Our decision guidance: if your model remains on the critical-update list, is updated through its official interface and reliably handles the apps you need, the end of production alone is not a reason to buy a replacement. Record the installed version and today's source check. Revisit the decision if Google changes the support row, an essential app stops working, or a specific unresolved fault affects your use. App playback alone does not prove security.

Repair: set a limit before paying

First establish whether the problem is the streaming device, its power supply, remote, cable or television input using the manufacturer's troubleshooting. Ask a repairer for a model-specific quote, warranty and parts availability. We have not verified repair scores, spare-part guarantees or local repair prices for this cohort. Weigh repair cost against support uncertainty and a replacement's total cost; a cheap accessory repair and an expensive board repair need different decisions.

Replace: define a concrete trigger

For first generation, plan a supported alternative for continued connected use rather than treating the last firmware number as ongoing maintenance. For the other models, use a confirmed support-ending notice, inability to install an applicable fix, a required service becoming incompatible, or an uneconomic physical fault as a trigger. Before transferring ownership, follow Google's account-removal and reset instructions. Do not reset a device merely because a directory reports a different firmware version.

Discontinued production is a separate fact

Google announced the end of Chromecast production on 6 August 2024, with stock available while supplies lasted and no change to the existing support policy. That announcement is not a universal retail sell-out date or an instruction to discard every Chromecast. We have not verified country-specific stock or reseller warranty promises.

What this guide does and does not cover

These eight generation-level rows are editorial guidance, not new records in the phone/tablet/router catalog. We have not mapped every regional hardware code or certified identical delivery in every country. No device-specific recall clearance is claimed. Physical safety notices, accessories and local service terms need separate checks. This guide uses documentary research, not hands-on reliability or repair testing.

How this guide was produced

DevLifeCheck separates manufacturer commitments, regulator notices and editorial interpretation. The editor checks the linked primary sources, records the applicable model and region, and avoids turning a missing date into an estimate.
