Features coming soon to non-Moto360 users:
►Ability to dim the ambient screen
=better night mode + battery saving
►Screen rotates when you connect the charger
=better feedback of the fact the watch is actually charging

I have recently upgraded to Huawei Watch from my 1st gen Moto 360. The new OLED screen, the lack of light sensor, and the inferior charger prompted me to update the app.

These features are coming soon in v4.65, but if you cannot wait, or would be willing to take part in the beta testing, you can join the community at:
