Hello~ I like this of the round-watches, so I bought two weeks ago in korea. I knew this google+ site, I upgraded the firmware the lastest k8 mini version. And then, I can’t use calling.
For one week, I am trying to solve this problem.
Now, I know this problem that I can’t check UMTS Mode at Bandmode Menu.
How can I select one un-selected parts in this UMTS mode menu?
I’m waiting for your godness help.
