Did you have it working when it first arrived or was it like this out of the box on day 1?
Normally this problem starts after custom watch faces are installed and then deleted.
The easiest way to confirm and possibly fix the problem is to flash the firmware.
If you are willing to flash the firmware then I will give you a link so you can download it.
If not:
A few details please.
Can you email me details of what you have sent to Gearbest so far please?
Conversation screen shots, video and proof of purchase etc…
Gearbest will be dealing with you - not Kospet. Gearbest has a duty to provide after sales support but they are not easy to deal with.
If you can include your email address for contact so that I can try to help.
UPDATE!!!
It turns out that the watch was fine when it arrived. Problems started when apps and faces were installed and removed.
The launcher finally failed when switching between the good old Bubble and Arc style app drawer.
Firmware flash is going to fix it.
Just incase anyone else has any problem here is the firmware update without the bubble launcher.
