@AYHAN-YILDIZ this looks to be a response generated by large language model AI. LLMs are prone to hallucinate, which means generating perfectly formulated responses that look credible but are wrong.

@halajos Hello,
no — this is not an AI-generated assumption. This information comes directly from Suunto support and has also been officially confirmed via email.Suunto has now initiated a technical investigation on the server (back-end) side to understand why, with firmware 2.48.16, a manual SpO₂ trigger that is not supposed to work is still functioning on some devices or accounts.
My own experience supports this:
I upgraded the watch directly to firmware 2.48.16 when I first received it
The first 3–4 manual SpO₂ measurements worked perfectly
Then the manual measurement suddenly stopped
Since that moment, it has never been possible to start a manual SpO₂ measurement again
This behavior strongly suggests that the issue is not a simple firmware bug, but rather related to a server-side configuration, trigger, or feature-flag change applied after synchronization.
Therefore, the statement that “manual SpO₂ was removed in 2.48.16” does not appear to have been applied uniformly or simultaneously to all users.
In short:
this is not speculation and not AI-generated — it is a confirmed issue currently under technical investigation by Suunto. -
@GiPFELKiND hi;For clarity:
Manual SpO₂ was not working on my device. I performed a factory reset, and now manual SpO₂ works correctly via the widget.It was stated that this feature was removed in firmware 2.48.16.
If that is the case, why does it become functional again after a factory reset?I would appreciate a clear and official explanation.
-
Funny thing, I tried the manual Spo02 measurement on my 9 peak pro (on 2.48.16) and the thing promptly, immediately, crashed and turned itself off.
How the f**** is that considered even remotely acceptable ?
I hate, absolutely hate how since the last few years Suunto firmware stability just became a gigantic joke it’s so awful, it’s like they don’t even try it !
-
@Elipsus Vertical2 is working perfekt. Also after 10 times of o2 measurements.
-
@AYHAN-YILDIZ @Elipsus I can confirm that the SpO2 widget is working on field test firmware. I have no idea where the information stating this was disabled was generated from.
-
@Sportsfreund I understand what you are saying, but there is a difference between seeking advice or help vs complaining.
But I agree which what you are saying partly. I would not agree that “Nobody goes to a forum if everything is great.” I came here and I think others have as well to lend support and celebrate Suunto.

No time to show on top screen when using 7 fields screen.

During an activity, the music controls cannot be operated via touch. Can anyone tell me where I can change the settings so that the controls also work with touch? Also, it seems that creating a custom battery mode isn’t possible on the V2, is it?
-
@tuxbuster It is not possible to enable touch for music controls during exercise. For all AMOLED watches custom battery modes are not available.
-
@Brad_Olwin Thanks for the feedback. Now I can stop looking for a solution and finally get some peace of mind again

@GiPFELKiND İşte Suunto’dan gelen yeni geri bildirim mesajı
Dear Customer,
Thank you for contacting us regarding the manual blood oxygen saturation (SpO₂) function on your Suunto watch and for providing your firmware version information (2.48.16).
We have confirmed the issue you described with our engineering team and would like to provide the following explanation:
First, we need to clarify the statement you heard online about the “feature being removed.” Your Suunto watch has always supported two blood oxygen monitoring modes: one is automatic monitoring during sleep, primarily used to analyze blood oxygen levels during sleep stages; the other is the instant measurement you mentioned, triggered manually via the widget.
Previously, some users encountered errors or malfunctions with manual blood oxygen measurement in certain firmware versions, mainly due to software-related issues. Our engineering team has now fixed this issue in the background. By performing a factory reset, you cleared any temporary data and configurations on your watch that might have caused the function to malfunction, thus allowing the correct function logic to work properly.
We hope this information clearly answers your questions. We are committed to continuously optimizing product functions and user experience through firmware updates. If you encounter any further issues, please feel free to contact us for assistance.
Wishing you a pleasant day!
Best regards, -

Shouldn’t a factory reset fix things, if anything at all? For me it doesn’t make much sense.
-
After a few weeks of testing, the issue started to occur again.
The OHR sensor turns off without warning and does not turn back on until the watch is removed from the wrist or a forced restart is performed.
-
Nothing. Even after the FW update, the issue with my V2 persists, but only on my left wrist — the one with this tattoo.
It doesn’t happen with any other sensor.
Suunto, do something!!
-
@Manuel-Extreme how can Suunto do anything about your tatoo…?
I suggest you move the watch to the other arm, to the underside of the tatooed arm or higher up the wrist. -
@Egika The sensor crashes. It turns off and won’t turn back on until I remove the watch and put it back on my wrist.
This happens in particular after using the heart rate strap for an activity.It doesn’t happen with any other sports watch. It didn’t happen with the Vertical 1 either.
For this reason, I think it’s a software management issue that should be analyzed by Suunto.

I am happy 9pp user. But sometomes i want to have bigger screen, maps. I am debating v1 vs. v2. Each have their own strengths and weaknesses and mostly these are perional or based on user preferences and use cases.
The biggest thing for me is screen i think. Mip is nice since you always see all the fields but still in challenging conditions mip is hard to see as well.
My eyes are not as good anymore (no glasses yet needed) but i think AMOLED would be better screen and easy to read in any condition?What i do not like is that you have to always press button or activate screen to see all the data on screen. Also i did not yet see how screen looks on v2 when AOD is used during navigatigation - is it hard to read in that mode during navigation activity?
Most poeple are saying when they tried AMOLED they can not go back to MIP.
Thanks anyone for feedback and thougts. Have a happy and healthy 2026.
edit: i can get v1 and v2 for the same price in EU. So decision is even harder
