Suunto Ocean update 2.51.28
-
Ok, so it’s been a few days since update, some feedback:
BUGS:
snooze alarm, wake up, wait for sleep summary to show and then dismiss alarm - somehow it freezes even longer than before
So this one is definately not fixed.watch shows notification and vibrates of incoming call, even if you answer the call.
logbook shrunkened, lost dives and activities over ~1 month old.
battery usage increased slightly (~1-3%/day) - guess this is the price of better menu performance.
ps. OxygenOS 16 + SuuntoApp 6.9.11

Just noticed this too! Hoping it is a bug as that’s not good imo.

@Dimitrios-Kanellopoulos - Is there an updated Suunto Ocean User Guide for the May 2026 software release?
-
@GS-111 I would also like to see the updated user guide. What does e.g. dynamic depth graph mean?

Hi!
I’ve been having a problem since the firmware update.
It updated automatically on its own last week. On Saturday, I went diving, and as I started my first dive, the watch restarted on its own!
After that, a message appeared saying something like “algorithm calculation error” along with a red warning icon—it wasn’t a lockout warning.
I used it on the next dive with the same warning. In the afternoon, I restarted it from the menu, and on Sunday while diving, the red error warning popped up again. The icon looked like this:

It kept giving me readings throughout the dive (deco time, etc.). I think the Tank POD’s battery is low, because the pressure would appear and disappear, and I also noticed that the altitude wasn’t correct—on land, it told me I was at -X meters.
What could have been the problem, and what can I do? Has anything like this ever happened to you?
Thanks!

After the dive and crash, sync the watch and send the logs from the app as soon as possible.
