"Intelligent Wifi" fails to switch to cellular data when connected to WiFi device that does not provide internet

"Intelligent Wifi" is enabled  - I even enabled the labs and tried the "switch faster" option.

I have 5G for voice and internet access.

Connecting to a WiFi device that does not have internet access, makes the phone disconnect from the cellular data, so the phone is offline.  - disconnecting the WiFi restores 5G internet access.

I upgraded to Android 16 /OneUI 8 , and it has "intelligent" Wi-Fi" 8.0.0   - Same issue - until I figured it out:

This is due to this ultra-stupid approach to mis-communication:

Samsung decided to make a big  big popup :""Internet may not be available"  - really? - that was indicated in the wifi-list even before connecting.

 

It offers three choices: "Connect only this time"   Should be "Use this connection only (drop others), this time"

"Always connect"  :  Should be " "Use this connection (drop others) only this time - and add a rule so that it happens always, you can find the rule in..."

"Disconnect"  :  Should be "Disconnect the wifi device" 

Where is the fourth, and only desirable selection?  "Connect and allow traffic on this subnet" 

- well, some amateur UI designer decided that using "back" button, not selecting any of  the first three does just that.  "Leave the f-ing connection alone and keep internet connection as well" is hidden by pressing "back" 
The level of UI design stupidity is horrifying here, the network offers DHCP and a route to a very small private network, clearly not internet.  There is NO reason to offer convoluted options to break internet, when a device clearly does not offer internet.
Will Samsung read and fix this? - ever?

Maybe enable mobile data always active under developer options

Great suggestion, could be dangerous in case it ignores roaming setting, but I tried, and unfortunately, the phone still drops the 5G data connection. (I just get an Wifi with exclamation mark as the 5G symbol is removed - as before)

Maybe automate with Tasker and autonotification and turn wifi off when it comes with no internet prompt?

The most essential "Wifi Device without internet"  I try to use is to interface with the plane's ADB-S (for traffic monitoring)  - and still be able to have internet access for the "Electronmic flightbag" to recieve updates on NOTAM / METAR  weather information  and so on - so even as I am a Tasker user, disabling wifi while in the cockpit does not really solve anything :smiling-face:

You are not giving up :smiling-face:    - The phone runs a "digital flightbag" - so it provides aviation maps, frequencies , weather, NOTAM etc  (updated from cellular network) - and nearby traffic (from said ADB-S device)  - splitting it it up would add devices/clutter.  It is easier to just skip updated for one or traffic. (and just imagine the laughs it would get from a copilot with an iDevice )   :smiling-face:   
I'd love to see Samsung actually participate in solving such issues, or at least acknowledging it as say "update will be out soon"

actually, the simplest solution it to keep using the Note 20 Ultra, which did that perfectly - but it is quite a sad outcome for the latest Samsung "flagship".
