Suunto Race 2 constantly rebooting — firmware 2.56.18, confirmed via device logs
-
@viduc @thorlap71 are you both using always on display? Which watch face?

@isazi
So far I have tested Vector Classic, Outback Adventure, Race 2 (default watch face), and lastly Modern Analog. With the exception of the Modern Analog which has run 16 hours without any crashes, all other numbered watch faces I tested have been crashing every 20-30 minutes.Here’s what can be inferred from the logs:
The bug is most likely in the shared low-power/AOD rendering component (“c-helper-lowp”) used by multiple of Suunto’s stock watch faces — specifically in the native code that looks up a glyph from the packed bitmap font asset at the randomized (x, y) position computed by aodMove(). Because the position is randomized every minute via Math.random(), only some resulting offsets are byte-misaligned, which explains why the fault is frequent but not constant, and why different watch faces (different eW/eH/tarDis parameters and different font assets) produce different crash rates without eliminating the bug. -
@elbee yes, it’s from the same email address with suunto app
Here’s the excerpt
“At the moment, we have not received any confirmed reports regarding this specific issue with firmware version 2.56.18. It is still recommended that you update your watch to the latest version. To help us investigate this further, could you please submit the device logs through the Suunto App?” -
@viduc suunto support isn’t the most professional support organization.

@isazi I have Always on display off and Raise to wake display only. I’m using Athletics watch face. I experienced another reboot a couple of hours ago.

@isazi @viduc In comparsion with yoor crashes mine reboots are less frequent. It usually occurs once 3-4 days, but it is a week old watch. Don’t know what to do really. Isazi, you are a moderator and a knowledgeable person on the issues, should I return the watch or wait for this issue to be resolved in future updates? What’s your take on this?

@Thorlap71 it is not up to me to say, I have a Race 2 but with another firmware and it never crashed on me, and I have not seen these random reboots in daily mode reported anywhere. In your case I would ask for a replacement watch and see if the behavior is different. I will forward all this info to Suunto anyway.

@isazi I was contacted after the reboot phenomenon returned on a new watch after being replaced due to the phenomenon, meaning it happened on two new watches. We downgraded the version in the hope that it was a software problem.

@Danny-poleg Before trying to get my watch replaced because of reboots, do you think I should try to revert my watch back to 2.48.16 firmware which is the only previous version available in my “Select OTA pkg”. Is this a reasonable thing to do?

@Thorlap71
Personally, I haven’t tried it. Someone I spoke to did it and I still haven’t received an update from him on whether it had any effect.
