So, I am running GC on a Hawei (sp?) honor6x with android 7, and it is fine most of the time, but I have noticed this with my vivoactive3, original vivoactive, and vivosmart hr, if I open GC, such as to update my weight, it almost instantly d/c the watches from the phone, and usually comes back together a few minutes or so after leaving the GC app. (It can run in the background at times, but not active) I have seen it do this on my wifes phone as well, but it typically isn't an issue with my 520. Sometimes it takes an hour to even reconnect on its own, and forcing it doesn't seem to help. (I can usually make it sync from the watch, without opening the app, but that seems like a bad answer...)
