Hey, you're right! Haha I guess they fixed it and I just hadn't tried it. Thanks!
And nope, my bad, it's not the FULL keyboard (well, it is, but not what I meant). It turns out it IS different on tablet and on phones. On the tablet, there's an Extended Layout option, and that would cause the mic to disappear on landscape on the tablet. On phones, you only get the SHOW ARROWS option, but I never tried that on phone.
Now that I've tried it again, the mic is back on Extended Layout and Landscape mode on tablet, so thanks!
