I just noticed that there is one speaker (right of the blackview logo) that produces sound. In the manual it just labeled that one speaker and not the other one. Is it just the one that works??

I am guessing that the other opening is for the barometer / altimeter

That actually makes a lot more sense than it being a speaker. Thanks for you're reply! I'll just keep monitoring this post if anything else comes up.
