whats this blue teardrop with 4 in it?

humidity in the AMS. Change the desicant.
Be aware that the AMS humidity sensor can take a couple hours to stabilize. If you just filled it the number may stabilize at a lower level.
I was told this also, but the last time I changed my desiccant it was updated in minutes. I was surprised.
It probably depends on the type and amount of desiccant you use in the AMS.
