I just checked:
Android App 1.0.38 (2214) – same as yours.
However when my firmware says 1477971088.
Whenever I try to update the firmware it says:

Image Info:
Current Build: 1477971088
New Build: 1477971088

And in the message-box it says:
Downloading latest firmware..
Successfully downloaded newer firmware file!
Unpacking firmware… Image loaded.
Ready to programm device

So it looks like there is something wrong with my update-process..??
