Suppose you’re rocking a Garmin Fenix 8, Enduro 3, or Tactix 8, and you’ve joined the Garmin Public Beta program. In that case, there’s a new update headed your way — Beta Version 15.33 is now rolling out over the air (OTA).
No cables, no desktop syncing, just a quick tap on your watch, and boom — you’re up to date.
But let’s be honest — is this update worth your time right now? Or should you hold off for a bit? I’ve broken down everything you need to know, step by step, in plain English.
Who’s Getting This Beta Update?
This one’s currently rolling out to 50% of beta program users. If you’re already signed up, your watch might get the update within 24 to 48 hours.
Feeling impatient (like me)? Good news: you don’t have to wait.
You can manually check for the update anytime by heading to:
Menu → System → Software Update → Check for Updates
Even if you’re not in the initial rollout wave, this trick often works — one of the nice perks of being in the beta program.
Not signed up yet? You’ll need to enroll in Garmin’s Public Beta program to get this or future beta updates. It’s easy to do, and Garmin has a guide for that right here.
Devices Compatible with Beta 15.33
Here’s the full list of Garmin watches getting this OTA update:
- Fenix 8 AMOLED (43mm, 47mm, 51mm)
- Fenix 8 Solar (47mm, 51mm)
- Enduro 3
- Fenix E
- Tactix 8 Solar
- Tactix 8 AMOLED (47mm, 51mm)
What’s New in Garmin Fenix 8 Beta 15.33 Change Log
Garmin hasn’t released a long changelog this time, but here’s what’s confirmed:
- ECG and Dive features stay enabled ✅
- Minor internal improvements (across GPS, software, wireless, touchscreen, etc.)
- General bug fixes and refinements from earlier beta feedback
Nothing groundbreaking, but if you’re a regular user or a serious athlete, these small tweaks often make your device feel smoother, more responsive, and more reliable during workouts or outdoor adventures.
Once the update finishes installing, your watch should show these version numbers:
| Component | Version |
|---|---|
| Software | 15.33 |
| GPS | 5.05 |
| Sensor Hub | 34.12 |
| Wireless | 28.85 (or 28.27) |
| Touchscreen | Varies by model |
To confirm everything updated correctly:
Menu → System → About → Look for the “Host” version. It should say 15.33.
How to Roll Back (Downgrade) Beta 15.33?
If version 15.33 doesn’t sit well with your watch, Garmin does let you downgrade to the last stable release. Each device has a .zip file and instructions for rolling back.
But heads up:
- Once you downgrade, you can’t reinstall this same beta version (15.33).
- You’ll need to wait for the next beta to go live.
- Backdating resets your watch, wiping your settings, custom layouts, and profiles.
So, make sure you back up anything important before you go that route.
Where to Report Bugs for Garmin Beta Software
Spot a glitch or hiccup? That’s what beta testing is for!
Here’s how to report issues:
- Post directly in Garmin’s Beta Bug Reports forum
- Check the Beta Wiki if you need help with things like freezing, crashes, or file access.
Your feedback helps Garmin improve things for all of us.
Final Thoughts: Is It Worth Updating Now?
Yes.
If you’re already in the Public Beta program, version 15.33 is a solid update. It doesn’t strip features like ECG or Dive, and the minor stability improvements are worth it, especially for high-performance watches like the Fenix 8 or Enduro 3.
Even if you don’t see big changes on the surface, these kinds of updates usually make the watch faster, more accurate, and better at syncing, which adds up over time.
