This smart watch doesn't show notifications on screen. it just vibrates. all my Smart watches in the past gave me on screen notifications. the notification on phone and app is turned on. it also disconnects from phone. once I turn app on then it connects. this is also annoying. I contacted seller and they want me to send a video. It's very bizarre. How can I send a video of this. I find all sellers on AliExpress ask for video regardless of what the problem is. This why I'm shopping less from AliExpress and more from Teemu. I used to always shop from AliExpress and their after sales was much better.
