Fenix 5 - baro/alti crazy reading

old problem on new watch ?
got this new unit last friday, thats are some pics of the alti/baro sensor crazy reading, same thing happened to many f3 units. Calibration will work for less than 2 minutes, than the pressure reading start raising or fall down. Someone else with the same problem ?

How do you find this?

And I was sleeping...Aliens took me...IoI

Here the same since 6.83.

:(:(

Yup, same here. Got the watch a week ago Monday and have had same issues. Emailed Garmin yesterday about them. The only way things stay steady is if I turn things off of auto. Recalibrate all the time!. By the way, I am on FW 6.0 not on beta

I'm on 6.00 too. Recalibraon last less than 2 minutes :-(
the worst thing is that the recorder altitude during an activity is the barometric one, so the recorded total ascent from start to finish is completly wrong and useless

Now also temperature is getting crazy.......

Mine went wild yesterday. Showed my home at about 3000m (our highest mountain is about 2200m). Then went for run after calibration and evidently managed to run from +24m to -972 metres over 10 km.
reading more realistic today.

Yesterday I installed the beta then reverted to the 6.00 with total reset.
Today seems ok... let's wait and see

Same behavior also for me, using the 6.83 beta :

After a hard reset, everything is OK during 1 or 2 days max. But from the 2nd day, the altimeter randomly start to rise with no limit, whatever the calibration or not.
Then, the bug comes back every day in my case.

1st example :
At the end of the day the altimeter start to rise to the watch display limit : 20 000 meters (the rise duration is about 30 - 60 minutes)
Then I just take the watch off my wrist, and leave it alone and powered on on a table for the night.
At the morning, the altimeter was at the opposite : -26 269 meters, but with a flat graph displayed on the widget.
Then I perform a calibration, and it's OK for the all day...



2nd example :
But at the end of the same day, the altimeter rise for no reason again.
I take the watch off my wrist immediately and leave it on a table powered on.
And then, the altimeter stop immediately to rise, and begin to decrease...
After half an hour, I put my watch on my wrist again, and the the rise restart again and higher !!! (Am I a mutan or something ???)
I take it off again for the night, and surprise at the morning, everything is OK and the altimeter display the correct data (no calibration needed this morning, perhaps because I didn't let the altimeter reach the 20000 meters)


I've also notice these side effects when the bug is occurring :
- no more climbed floor is detected
- the thermometer is decreasing : around +10°C on my wrist !!!
- A full calibration doesn't stop the altimeter to rise (enter manually the altitude and the sea pressure)

I am an early owner of the F5 sapphire (since april '17) and this bug started at the end of september, start of october, with the 5.40 firmware
I've already return 2 different units to the Garmin support for this issue, but each new unit sent back by Garmin is still facing the same bug.

Meanwhile, because it's the 3rd unit in my possession, I'm not sure it's a hardware issue (or I'm very unlucky), and very disappointing for such an expensive device

Hope Garmin read all of our posts and take them into account.
For now I'm "playing" a bit with this bug to collect maximum of details, but I'm afraid I'll sent it back again to Garmin a 3rd time, and this time with asking my money back.

I was having this exact same problem for about a month. Try placing the watch in warm soapy water for 30 minutes, then re-calibrate. I saw this in the official Fenix 3 literature somewhere. I do this every couple of days and the problem has gone away.

I believe charged synthetic particles from winter clothing or other sources cause the pressure sensor to malfunction but have no definitive proof. I was doing mobility exercises on the floor where the watch would be rubbing on the carpet fibers. This is when the huge errors started. Now I take the watch off for this activity, this is when I soak it. I have been trouble free for a while now.

This may sound crazy but try it.
