Hi!
I have a k9 3g watch, stock firmware, i didn’t root it, i disabled the health applocation though.
The strange thing is when i try to check inbox (inbox app from google) or hangouts on 3g, i receive a “no internet connection” message. It’s work on wifi.
On 3g i can browse, or listen spotify, so i have internet connection, except on the google related apps.
The applications are up to date.
Is anyone struggle with it?
Thank you!
