Where can I found what has been improved/corrected in the last firmware update (v.49?). Thanks in advance
As far as I know, they enabled data transfer via USB. So now you should be able to connect the K2 to your pc via USB and copy the videos.
You two remind me to make a log of firmware update, and it has been uploaded to firmware document.
Good idea. But you made a little mistake.
1. K2.20180925.V0.39- fixed 720p setting in App.
This bug has been fixed in V47, not V39 :-)
