If you do a "device reset" it seems to force an update, at least it did for me.
Now as for that annoying "Ok Google" showing up every time the watch face comes on - I tried the 5 searches but it is still there. SUPER annoying. Any other ideas?
I received my Motorola Quick Charge 2.0 adapter today, and though it does charge fast, I don't think the HTC update has enabled the full Quick Charge 2.0 feature.
