PC Connection

Hi
I received my AllCall W1 yesterday and watch runs fast but I have some questions:

  1. When I connect the watch to my PC (Windows 10 64bits) my PC don’t let me see the files of the watch. I don’t see de device in the devices manager… I can see it now but it’s very slow!!!
  2. I changed bluetooth watch name and after that I couldn’t see the watch through WiiWatch again from my phone. 
  3. What keyboard are you using?
    Regards
