Garmin Confirms the Fenix 8 Brightness Bug, and the Fix Has No Date Yet

Your Fenix 8 should not keep glowing like a flashlight after you walk back indoors. A growing number of owners say that is exactly what it does, and Garmin has now admitted the problem is real. In an October 7 reply on its support forum, a company representative said engineers know about a concern that can leave the display fully lit after time in bright conditions, and that a fix is pending for the next software update.

The catch is the part owners care about most. Garmin has not named a software version, a date or the full list of affected watches. So for now, if your Fenix 8 AMOLED is running out of juice faster than it used to, you have a likely suspect and a ten-second workaround.

What Owners Are Seeing

The original forum report describes a fairly specific setup. With Always On Display enabled and the wrist gesture switched off, the watch ramps up its brightness in strong sunlight, which is normal. The trouble starts afterward. When the wearer steps into a shadier spot or goes inside, the screen sometimes fails to dim again and stays at a high level.

An AMOLED panel that stays bright is a panel that keeps eating power. That lines up with the complaint thread, where owners describe battery life dropping sharply on days when the watch gets stuck. One commenter said the bug made a dramatic dent in endurance, and another was frustrated that an issue seen during the beta ended up in the public build. Those are owner opinions, not measurements, but they point the same way.

The Bug at a Glance

Based on Garmin’s forum reply as reported by Gadgets & Wearables, Android Authority and Garmin News. Garmin has not published a list of affected models.

Why 23.39 Did Not Clear It Up

Many owners expected the stable 23.39 release to tidy up the loose ends from 23.31. For this particular fault, that did not happen. Several owners say their AMOLED Fenix 8 still sticks at high brightness on 23.39, so installing the newest build is not a reliable cure. This is also not the only complaint attached to that software cycle. Earlier reports described wrist heart rate readings dropping out entirely after the 23.39 update, which makes the next patch an important one for Garmin.

Garmin’s pattern with large update trains is worth knowing. Features and fixes often arrive unevenly across its range, something we saw in the Garmin Q3 2026 update, which added fall detection and voice control with uneven model coverage. If your watch is a Fenix 8 variant, expect to wait for the specific build rather than assuming it lands everywhere on day one.

How to Check Whether Your Watch Is Affected

You do not need a lab for this. Garmin has not published a figure for how much battery the bug costs, so the simplest test is behavioral.

1. Look at your settings. Check whether Always On Display is on and the wrist gesture is off, since that is the combination owners keep naming.
2. Take it into sunlight, then back inside. A few minutes outdoors is enough. Watch whether the screen drops back to a normal level.
3. Check your battery trend. If you are losing noticeably more charge on days when you spend time outside, that fits the pattern.
4. Tap or press. If the display snaps back to normal after a touch or a button press, you have probably found it.

Turning the wrist gesture on is our own suggestion, based on the setup owners say triggers the problem. Garmin has not listed it as an official fix, so treat it as a sensible experiment rather than a guarantee.

Is the Fenix E Affected Too?

One report says owners of the Fenix E are seeing the same stuck-brightness behavior on version 23.31. That has not been confirmed by Garmin, and the company’s reply did not list models. If you own a Fenix E and notice the screen staying lit, the same tap-or-press workaround is worth trying, and it is worth adding your experience to the forum thread so Garmin has a clearer picture.

What This Means If You Are Shopping

This is a software bug, not a hardware flaw, and software bugs get patched. It should not scare you off a Fenix 8 if one is on your shortlist, though it is a good reason to read recent owner feedback before buying.

Frequently Asked Questions

Has Garmin confirmed the Fenix 8 brightness bug?

Yes. A Garmin representative acknowledged it in a support forum reply on October 7, 2026, saying a fix is pending and will come in the next software update.

Which software versions are affected?

Owners first reported it on 23.31 and say it continues on 23.39. Garmin has not named an official list of versions or models.

How do I stop the screen staying bright?

Tap the touchscreen or press a physical button. That should return the display to its normal brightness until the watch is exposed to bright light again.

When will the fix arrive?

Garmin has not said. The company only describes it as pending for the next software update.

Does the bug really drain the battery?

That is the strong suspicion. A display stuck at high brightness uses more power, and owners report faster drain. Garmin has not published a number for the impact.
