Keywords, Call and SMS Message continuity problems and solutions.

Yes it worked flawless at Android 9 at my Tab S5e, then the following happened.

Both my phone and the Tab S5e got a firmware update, the Tab S5e to Android 10. At this time I tried everything to get Call and Message continuity working again. But nothing worked.

* First I removed and disconnected all phones and this tablet from my Samsung Account, I recommend that you too do that first. ( You see after for example a factory reset you get multiple accounts for a same device, so solve this first, remember your password and have your phone reachable for SMS verification for when you connect all devices again.
* Second, I assured nothing was wrong with the home router internet, by factory resetting it. A lot of work, but still didn't work.
* Third, although everything worked for perhaps an hour, it would simply stop.

Now you want to know what in my situation was the cause and actual solution:

*** When I received firmware updates, I also installed the COVID 19 app that is different from country to country, ( Holland here ). This turned out to be the cause.

At day I enable from Google Settings the COVID 19 app tracking over Bluetooth other people that you meet and see in case one has COVID 19.

But this is the solution, at evening I disable in Google Settings the COVID 19 app since I then don't meet people anymore.

It turned out that when in Google Settings the COVID 19 app tracking is enabled, the Call and SMS Message Continuity is simply not working, ( in this country Holland here at least. ).

So the COVID 19 tracking app unfortunately here was the cause, this took me weeks to figure out, I had COVID 19 app tracking over Low Energy Bluetooth simply running all the time.

Conclusion: Follow these instructions if you experience these problems with Call and SMS continuity.

I think the by Google supplied COVID 19 tracking option does something with the phone its identifier and ironically, the time it works fine is equal to the time that a device rotates Bluetooth Keys to other phones from people having the anti corona app installed.

Good luck troubleshooting if it doesn't work.

One more thing, Call and SMS continuity is in advanced settings, but it is named a little different than the English term in this forum though. And if you cannot find it you probably have Verizon firmware that doesn't have it at all.

EDIT: Update at 2020 month 11 day 28, November 28 2020

The following seemed to resolve.

I got a firmware update for Tab S5e with revision: T720XXU1CTK1
I also downloaded in google play store a program that redirects you to the latest google Play Service Framework

I would recommend to update to latest google Play Service Framework.

https://play.google.com/store/apps/details?id=com.kyumpany.playservicesupdate

That will only make you sure you have the latest google framework.

You can find it with ' Play Services Update - Update to the latest '

Then you will be getting the official latest google play service framework. Reboot all your devices. And the problem I had and probably others is no more.

It now works again as in the past.

Speculation: I do not have to disable the covid app anymore, it can run fine without the first guide mentioned things. The covid app is part of Google Play Service Framework. But I think the latest firmware update for Tab S5e might also be why it now is finally working.

This procedure took 2 months at least to be sure to be solved. Let us hope something like Covid never happens again.

Pull down the status bar, in the quick toggles you see a little phone icon, by default at the 2nd quick toggle page. Move that quick toggle to first page by rearranging the quick toggles. Every time you connect your tab s5e with wifi you have to reactivate call and message continuity with that quick toggle so you need it manually a lot. Then both calling and sms work flawless. Until you disconnect wifi. If you don't manually quick toggle after connection with wifi you will only receive missed call notice or SMS only.

It's a workaround.

Tab s5e Android 11 came over air. Call and message continuity did no longer work. Did factory reset of Tab s5e. Still didn't work with exception of SMS.

Solution turned out that in the mobile phone my Galaxy S8 something must be done.

It's called Reset Network Settings.

This is what it made it work, had to do this in my Galaxy S8.

Go to your mobile settings menu by sliding down the status bar:

After that choose Main Menu and Settings.
Navigate the list of settings tap General Management and Reset.
In the next step select Reset Network Settings.
Read the information in front of you and choose Reset Network Settings one more time.

Don't forget to setup Call and message continuity again. It should work.

This might be necessary after every firmware updates for mobile or tablet.
