The WiFi off seems to generally resolve problem but there's some other background issue also.
I have been running with WiFi off and no dupes at all. I periodically have issues with signal either from cell provider (5G ATT) or cable internet provider (Spectrum/TWC) which will prompt me to toggle wifi on or off on occasion.
So I turned on WiFi one evening in bed and since not using laptop, no big deal, dupes not an issue.
Next morning, get up, forgot about WiFi being on, dupes started immediately.
Thinking I know how to fix this, turned WiFi off and dupes continued for some time.
This is a purely speculative thing here but a couple of observations. This was done by sending texts to myself via phone and Your Phone app on laptop.
- With WiFi off on phone (Samsung Note 9) if I send message via phone SMS TO MYSELF, there is no bounceback message on phone or Your Phone app. It leaves the phone but never returns.
- With WiFi off on phone and I send a message via the Your Phone laptop app, I see both the outgoing and return message on both phone SMS app which is the Samsung standard app, AND the Your Phone laptop app.
It seems like the Your Phone Companion (phone) app and the Your Phone laptop app maintain some sort of connection that I am at a loss to understand what that connection is, and how it is maintained.
So, right now, I have WiFi OFF on phone, WiFi ON, on laptop, AND BLUETOOTH OFF on both phone and laptop.
How are the two connected if both WiFi and Bluetooth connections are theoretically severed?
I see this in the notification bar that you can make visible by swiping down from top of phone. It acts like a bluetooth connection but the two apps maintained their connection even after I had killed Bluetooth on both phone and laptop.
So how are the two devices connecting and staying connected without WiFi or Bluetooth?
