老是手表上有莫名其妙的来电 但是手机上不显示

为什么蓝牙手表老是有莫名奇妙的电话提示但是手机上没有来电提示通话记录里也没有手机手表上都没有

Watch Shortfalls

It has 6 built in watch faces. While there’s many others to choose from, only one can be installed, and that disappears in a day or two requiring reinstalling.

It does not have ECG capability although the AD says it does

The beautiful watch band needs adjusting to fit, but it appears impossible to adjust it, even though the supply the tool.

Otherwise, it’s a gorgeous watch and the provide a black band as an extra, so it’ll fit without the fancy band.

Love the watch hate the app

The watch is great but the app is terrible. Can’t customize much and can’t even delete watch faces you don’t like. Admins please update the watch and app to customize it to what we want.

Cannot connect with GPS

I am not able to connect to the GPS feature. Error reads: Please connect to APP and enable GPS location permission. I have done this, reset and performed steps again. Still will not connect.
