Garmin is pushing Software Version 17.33 to the Venu 4 and Vivoactive 6, with the Venu 4 getting a list that rises above two dozen changes when its device-specific fixes are counted.
The stable update is rolling out globally and should reach all eligible watches “in the next few days” once users sync through Garmin Connect Mobile or Garmin Express, according to Notebookcheck. This is not a beta build. It follows Software Version 16.37, which arrived in late March with around half a dozen changes and no new features called out.
Garmin turns beta work into a stable Venu 4 and Vivoactive 6 release
Software Version 17.33 is the stable result of beta development that began in early April, according to the source material. Garmin’s changelog lists 24 shared changes for the Venu 4 and Vivoactive 6, plus 6 Venu 4-specific changes.
That means the cheaper Vivoactive 6 gets almost the full package rather than a token maintenance patch. The Venu 4 gets the broader list because it also receives fixes tied to calls, ECG behavior, Garmin Coach syncing, voice features and battery drain after phone-assistant or call use.
The update is heavily weighted toward reliability, a theme also seen in Garmin’s Venu X1 update. Notebookcheck reports that 17 of the shared changes are bug fixes, and 4 of those target issues that could cause either watch to reset unexpectedly.
“Adds support for Approach CT1 club sensors,” Garmin’s shared changelog states, alongside fixes for resets when adding apps through Garmin Connect Mobile, recording an activity, using WhatsApp on an iPhone, or viewing the evening report.
That mix matters because the reset fixes hit routine actions, not obscure edge cases. Adding apps, recording workouts and checking daily summaries are core smartwatch behaviors.
Venu 4 gets silent mode and fixes for calls, ECG touch behavior and battery drain
The Venu 4-specific side of the update brings one clear feature addition: silent mode. Garmin says it can be accessed quickly through the control loop or a button shortcut.
The rest of the Venu 4-only list is mostly corrective. Garmin fixes an issue where the screen could respond incorrectly to touch after an ECG reading, and another where users might not be able to accept an incoming call on the watch.
The update also addresses Garmin Coach workouts sometimes failing to sync to the device. Voice command, music and voice notes apps should no longer be accessible during an active call, based on the changelog.
Battery behavior gets a targeted fix too. Garmin says the update resolves an issue that could cause excessive battery drain after using the phone assistant or accepting a phone call on the watch.
MLXIO analysis: The Venu 4 changes point less to a flashy feature drop and more to cleanup around smartwatch basics: calls, touch input, coaching sync, voice functions and battery behavior. Garmin has not quantified any performance gain, so the supported takeaway is narrower: this build removes several named failure points from daily use.
For readers tracking Garmin’s broader software-maintenance cadence, MLXIO recently covered another changelog-heavy device update in $1,049 Garmin Update Drops 30 Fixes Owners Need Now. This Venu 4 release is smaller in device scope, but similarly driven by fixes rather than headline hardware news.
Vivoactive 6 receives the same shared package, including reset and workout fixes
The Vivoactive 6 does not receive the Venu 4-only silent mode or the Venu 4 call and ECG fixes. It does, however, get the full shared Software Version 17.33 package.
That includes Approach CT1 club sensor support and access to the keyboard layout menu by swiping up from the bottom of the page. The update also includes GCM Translations - 3.90 and general translation updates.
The shared fix list spans workouts, reports, weather, file uploads and responsiveness. Garmin says the update fixes a possible issue where the back and down key would not work for indoor climb and bouldering activities, and another where an upcoming race event might not appear on the device.
Swim tracking also gets attention. Garmin fixes pool swim workouts progressing through active steps without interaction, send-off time not vibrating during swim workouts, and rest-timer countdown tones during strength workouts sounding out of rhythm.
A few fixes target device state and syncing rather than activity tracking:
- Uploads: Fixes a failure when uploading an activity file to Garmin Connect.
- Saved files: Fixes devices with many saved activity files appearing unresponsive at times.
- Gear tracking: Fixes the progress bar shown after an activity not including the just-completed activity.
- Strength records: Fixes syncing strength personal records with Garmin Connect.
- Power modes: Fixes battery estimates when switching power modes for activities.
- Weather and watch faces: Fixes weather app updates and sunset/sunrise fields not refreshing.
The shared package also improves responsiveness when starting the timer and prevents automatic track detection during trail run activities. With a Garmin Golf subscription, it adds premium features including green contour data, enhanced CourseView maps and PlaysLike distance.
The changelog favors reliability over new feature marketing
The biggest split between the two watches is straightforward: Venu 4 gets the shared package plus six extra changes; Vivoactive 6 gets the shared package only.
| Area | Venu 4 | Vivoactive 6 |
|---|---|---|
| Shared Software Version 17.33 changes | 24 | 24 |
| Device-specific changes listed | 6 | Not listed in source |
| Reset-related shared fixes | 4 | 4 |
| Silent mode | Yes | Not listed |
| Approach CT1 club sensor support | Yes | Yes |
| Garmin Golf subscription premium features | Yes | Yes |
That comparison is useful for buyers looking at Garmin’s mid-range smartwatch lineup. The Vivoactive 6 is not being left far behind on this update, but the Venu 4 still gets extra polish tied to its own feature set.
This also follows Garmin’s wider pattern of issuing feature and software updates across selected smartwatches. Garmin said in May that select devices, including Venu 3 and others, were receiving features such as breathing variations, rucking activity, passcode and stage timer, alongside premium golf additions.
For wider consumer-device update context beyond wearables, MLXIO has also tracked forced interface and hardware-limit stories such as Roku Home Screen Redesign Hits 100M Homes—No Opt-Out and USB-C Flaw Locks OnePlus Nord 6 Out of Big Screens. The common thread is simple: post-sale software behavior increasingly shapes the device experience long after launch.
Owners should sync through Garmin’s named channels and watch the reset fixes first
Garmin says System Software 17.33 should reach all Venu 4 and Vivoactive 6 watches in the next few days once they are synchronized with Connect Mobile and Garmin Express. The source does not specify any special installation steps beyond those update channels.
The first practical signal will be whether the four reset fixes behave as intended in normal use. The listed triggers include adding apps via Garmin Connect Mobile, recording an activity, using WhatsApp on an iPhone and viewing the evening report.
The next watch item is whether Garmin follows this stable rollout with a smaller patch if early users surface new issues. For now, the supported read is that Software Version 17.33 is a broad reliability release with a few targeted feature additions, not a reinvention of either smartwatch.
Key Takeaways
- The update brings a substantial stable release to both the Venu 4 and Vivoactive 6 rather than a minor maintenance patch.
- Several fixes target unexpected resets during common actions like adding apps, recording activities, and viewing reports.
- Venu 4 owners get extra fixes for calls, ECG, voice features, Garmin Coach syncing, and battery drain.
