Nintendo Switch 2 firmware 23.0.1 released with fix for startup delay

• The update fixes an issue from version 23.0.0 that could make some software take longer than normal to start, pause, or close.
• Nintendo does not list any other changes in the patch notes.

What happened

Nintendo released firmware version 23.0.1 for Nintendo Switch 2 on October 1, 2026. According to the official update notes, this is a small system update that fixes a bug from version 23.0.0. The version number 23.0.1 follows directly after 23.0.0, which was released on September 10, 2026. That puts roughly three weeks between the two updates.

The bug could cause certain software on the console to take longer than usual to start, pause, or close. Nintendo does not mention any extra features, improvements, or other fixes in the patch notes beyond this one issue. Based on the available information, 23.0.1 appears to be a targeted maintenance patch rather than a broad system update with new features.

The same firmware update is also available for the original Nintendo Switch. That means 23.0.1 is not only an update for Switch 2, but also a maintenance patch for the older console family. In the shared description, Nintendo does not note any difference in content between the two systems, aside from both correcting the same timing- and startup-related issue from 23.0.0.

GameRant reported on the update and the patch notes on October 2, 2026. The summary also points to Nintendo Support, where the system update information for Nintendo Switch lists the latest version as 23.0.1 with a release date of October 1, 2026. That supports the conclusion that the update was officially made available through Nintendo’s own update channel.

Background

Nintendo describes 23.0.1 as a targeted fix for a problem introduced in version 23.0.0. The issue specifically affected software on Nintendo Switch 2 and the original Switch, which could respond more slowly when starting, pausing, or closing. That makes the update narrow in scope: the patch notes name one concrete problem and one fix.

The available patch notes do not include any additional changes. Based on the information provided, 23.0.1 is a small maintenance update without new features or broader system changes. There is also no indication in the supplied sources that Nintendo added interface changes, performance improvements, or compatibility tweaks. The only explicitly mentioned change is the fix for the software delay attributed to 23.0.0.

The update matters for two hardware lines at once: Nintendo Switch 2 and the original Nintendo Switch. That is important because the reporting is not limited to the newer console. Nintendo’s support page for Nintendo Switch lists 23.0.1 as the latest version and gives October 1, 2026 as the release date. That lines up with GameRant’s reporting.

The timeline around 23.0.0 and 23.0.1 shows Nintendo releasing two consecutive firmware versions in a short span. 23.0.0 arrived on September 10, 2026, followed by 23.0.1 on October 1, 2026. The available sources do not mention any other firmware releases in that period. There is also no confirmation in the supplied information that rollout differed by region; the sources only say the update is available and what issue it fixes.

Because the patch notes are so limited, it is best to stick to what Nintendo itself has stated. The sources do support that the update is official, that it arrived on October 1, 2026, that it is available for both Switch 2 and the original Switch, and that it fixes a problem from 23.0.0. The supplied information does not confirm anything beyond that.
